Hi Everyone, Thought I'd share a few photos/videos of the buggy I built. Its an edge designed Barracuda, stretched 100mm in the engine bay. Honda VTR-SP1 Engine (they call it an RC-51 in the states), 132hp V twin. Took about 4 1/2 years to build but definitely worth it.

haha, give me a cigar. I have spent a bit of time up that way riding both dirt and road and love that part of the country, spend quite a bit of time at Eden also,have a friend with a property there on the Kiah river .

Nice! Thanks for the video. I'm very intrigued by the front suspension on these. There is huge rake and looks to be lots of camber gain on bump but not droop. Also looks to be caster gain on bump. Anybody else have any experience with this setup? I would think it would work well.

Nice mate, Are you still down that way. I see from your link to youtube you have some pretty awesome toys.

The front suspension is pretty awesome, and the beast rides like a dream. I am no suspension expert, but the interesting thing about the front A-arm is that the mounts for each arm arn't parallel. This results in an increase in caster angle (think they call that rake in the state?) as the suspension is compressed. It is also designed so that at high compression, the front wheels travel into progressively more negative camber, which is designed to help keep the buggy from digging in when landing a jump.

I am an engineer by trade, but Tony who designs the plans at the Edge has been working on buggy designs for 25 or 30 years and I trust his expertise in this far more than my own. I know he works with lots of mini buggy racers to help develop the designs, and he won't let a design out until its perfect. He's also a top bloke and whenever I have had problems he is quick to respond via email. Might be worth sifting through their forum edgebuggyforums.com to see if you can get some more info on the design of your suspension.

The non-parallel arms do indeed add caster (and stability) as the suspension compresses, but not rake.

Rake is the angle between horizontal and the plane that the arms pivot on.

Beautiful looking ride, btw. - and that engine is a work of art. The torque curve must be impressive (and wonderfully flat).

Na i live in cold old VIC but get up there a couple of times a year if i can.

Thanks K-Fab. I had only ever heard rake used to describe motorbikes before, and thought it was caster. Now i know that rake and caster are different things (always good to learn new stuff).

And oh yeah, the torque curve is insane. after about 3k revs, it just pulls right up to redline around 10k. When i first drove it it was a new experience, the nose would lift when you hit the gas and I would loose sight of the road, had to steer based on the gap in the trees (bit more pressure in the rear air shocks stopped this now). The only problem is that the bike was geared towards top speed rather than acceleration, so first gear is a little long, even with a 14t front and a 60t rear sprocket. It takes a couple of seconds to get going, but once it does, its too much fun. I really want to try for top speed, which as its geared should be about 175-180 km/h (think thats around 110 mile/h), but i think that it will be the suspension or lack of equipment between the legs that would prevent that speed, rather than the engine.

Hey great to hear you have a race under your belt , looked like a pretty cool course nice and loamy plenty of room too. Ok question time .

Were there any other minis ?

Where was it ?

How did you go?

Was it a CAMS event ?

I got more but that will do for now :D

I got more but that will do for now :D

The event was called "Superior Engineering Short Course". It was at caboolture, about 30 mins north of brisbane.

There were 8 or 9 minis on the day, racing in a class called 'superlights'. A mini took overall first for the event.

Not a CAMS event, but there was scruteneering and safety regs, but they were pretty basic - just needed a fire extinguisher and window nets/arm restraints on top of what i already had.


It was my first event, there were 6 races of 2-3 laps each. Started out about 20 seconds off the pace over about a 4 minute course. Don't know how close I got but was much faster by the end of it. They started at 30 second intervals and unfortunately i was rostered first out in every race, so coiuldn't really follow anyone which meant it took me a while to get used to the track.

I managed 5th out of the 8 minibuggies (but think 6th, 7th and 8th all failed to finish a race or two resulting in disqualification). However, I was 14th for the day out of 50 cars in total, from modified 4x4's to side by side buggies, rockcrawlers, and a bunch of other cool machines. I was really happy with the result and am still smiling. The best part was that the only problem I had all weekend was a flat tire... which i only found AFTER i got home, think theres just some dirt in the bead so should be a cheap and easy fix. Gotta love a weekend driving without any real problems.

The good news as well is that It appears my buggy is pretty fast! Managed to keep up with everyone (any slowness was driver related rather than horsepower). There was a drag race as well, Screwed up the start badly but once I had it going i hung in there pretty well.

Thanks Talon, I can't wait til the next one, its in 12 weeks or something. So much to do before then, think my list of jobs just keeps growing the more I get done! Really want to move the fuel tank (its underneath the seat at the moment, don't really like sitting on 20L of petrol), put outboard rear brakes, panel in the sides, put an electric reverse in,window nets rather than wrist restraints, the list goes on and on.

I crashed. Not sure exactly what happened but the accelerator got jammed on and I took a corner wayyyyy too wide. Hit a berm of dirt side on at about 80+ kph. I got told I rolled 2-3 times, then flipped end over end and landed on the roof. I counted at least 2 rolls from the drivers seat but couldn't tell you much about it.

I'm OK which is the main thing.

Buggy basically needs everything behind the engine bay replaced, new arms, arm mounts, centre drive mounts. The steel has actually torn around where the cartridge joins the steel box section.
Needs new exhaust as both the headers and mufflers got trashed
Roof and bonnet are caved in.
New light bar (I just bought the old one too... damn!)
new roof panel
New engine bash plate
New rear suspension arms.
New seat, the mounts got torn out.


Basically, total rebuild.

I am tempted to go the semi-trailing arm (Think its also called a trailing LINK design) for the rebuild. Anyone have thoughts on this? I'll probably install an LSD at the same time just to see how it goes.



Here are some photos, it doesn't look that bad here, so I put a rule next to it so you could see how bent it was.

Thats how the back end is bent... you can see one rear upright is vertical and the other is on quite an angle. They are meant to be equal. (theres also meant to be another exhaust on the other side)

Also couldn't help posting this one of the heat before the roll. One of my mates got a photo of it upside down so i'll post that when he sends through a copy.

read this late last night, that sucks! Glad your ok. figure out what hung up first! From teh way things are tore up, i'd look long and hard to see how much twist is in the frame/cage work. A magnaflux kit wouldn't be a bad idea to check all your main tube junctures.

Hambam
07-17-2014, 03:06 AM
Thanks for the comments guys. I am not even going to look at it for another week. I am flat out at work and I know if I do 10 minutes on the buggy, it will be more like 10 hours the way I want to get stuck into it, although I might do a measure up just to see how bad it is. Magnaflux or dye is not a bad idea for the welds.

I think I figured out the problem. There is a steel tube next to the accelerator, If you push the pedal in hard, your foot is well clear of the tube. I think my foot got jammed between the pedal and the tube, so when I released it, my shoe jammed the accelerator pedal down. I was wearing sturdy leather boots so didn't feel the tube on the back of my foot as I would have done in racing boots or lesser shoes. Sounds stupid (and it probably was) but I think that must have been what happened.

Very tempted to do a semi trailing arm for the rear end, what are peoples thoughts? I'm a bit concerned with the toe change it gets through travel.

Xbird
07-17-2014, 07:37 PM
sounds like one of my very first setups (pitman arm setup) where the tie rod would pass over my right toes and trap my foot floored in a full left hand turn, not so good.

as far as the semi-setup goes, iirc, the toe change would be inclined to toe in to the inside of the turn when loading up in the corners, might help make it a bit tighter in the cornering (a bit oversteery). ?

Annnnd, here is my new rear end design. Its currently being cut at the lasercutters by a friend and he keeps messaging me photos of bits getting done. The progress is awesome but its driving me insane with only small snapshots of whats hapening. Hopefully its done by the weekend, as I am desperate to get this thing rolling again!

Looks good, but I recommend you get rid of all those holes. The cartridges have been known to crack through that area and every hole is a stress raiser.

TALON
09-04-2014, 02:04 AM
Or keep the webs as stiffeners but keep the arm mounts independent of them so they are not trying to do 2 jobs , that is when they fail .

Hambam
09-04-2014, 02:09 AM
Thanks for the input Iggsy, I was aware of the potential for cracking. The holes are so I can tune the suspension by mounting the arms in different locations. They are much wider in total than the original design, particularly the edge version which uses really narrow supports to save weight. The width of the arm mounts will stiffen everything up and hopefully reduce the risk of cracking. Also, Will seam weld the whole thing rather than stitch weld it. I did that for the last one and it was bent bad after the crash but no sign of cracking.

Good idea Talon, but its at the laser cutters already so too late to change. Im pretty happy with it though and its stronger than the original, so ill just see how it goes.

I figured it was to play with locations, i like the idea, and you can always beef it in spots later if it presents an issue.

I have thought about it before and considered a nice chuncky billet arm mount that could be bolted on in different spots, not just for that location either , but pretty much anywhere on the suspension front and rear. No doubt it will forever reside in my sketch book as idea.

Just got sent a photo from the lasercutters... Ooohraaaa
After this is completed, the buggy will have the following new features:

Front 260mm disk brakes and 4 pot calipers (over the older 180mm disks and single pots)

Rear outboard 210mm disks with 4 pot calipers (I will get bigger ones cut later, but still want to be able to run some 12" rims on the rear as I have a few sets of tires that need wearing out)

New rear drive section with an interchangeable live axle and limited slip diff centre section. Electric reverse via a starter motor.

- New exhaust
- New fuel tank (relocating from behind the seat to behind the engine).

09-11-2014, 06:56 AM
Well F%#$%%#%%###@*@(...

Just went through all the cutting. I have to say, the edges are perfect and the quality of the cutting is great

HOWEVER,

All internal dimensions are about 0.3mm too small. This basically means that nothing will fit together as designed, all the holes for machined parts wont' fit.

I guess its my own fault. The old laser cutter used to cut so holes were -0/+0.3, so a 100mm hole would be 100.0-100.3mm and I forgot to check what the new lasercutter used for tolerances... they probably dimension under rather than over, so its 99.7 to 100.0. Anyway, its just complicated things far more than it should have. Much of it I can drill out/grind out or modify to fit, but some of it needs to be very precise and if I attack it with a file and a grinder it will ruin a lot of the precision that I went to the laser cutter for.

I'm a bit pissed off I just spent that amount of money to make life easy and now it would almost have been easier to start from scratch.

Just had to vent that. This will be a big weekend I hope.

Hambam
09-13-2014, 04:16 AM
So far the under size holes haven't been to disastrous. It was only about an hour with a grinder and a file to get this together (not welded or tacked yet), and its all a very nice fit.

Also the new rear end will have a reverse gear! I am very excited about this as it will make things a whole lot easier. Also, our racing authority (CAMS) in Australia requires a reverse gear. I still can't get this buggy registered to race in big events, but it is a really good 'practice run' for when I build my next buggy.

4 of us are going in on a group buy to get some heim joints from the states. The $130 postage (Yes, that was correct) is a killer but split four ways it works out about $30 each which isn't too bad considering heims are $11 and over here they are $30 each minimum. I'm getting a lot of spares.

For those who made comments about the new rear end potentially cracking, see what you think with the new vs old side by side. I believe my new design to be substantially stronger but would be interested to see what you think.

Some photos (because thats all anyone really cares about anyway)

Here is the starter motor with the laser cut ring gear. Its currently just cut in mild steel. If it works that will be great, but if it fries the ring gear I'll have it recut in something stronger.

She sure is bent man , looks a bit like mine after the last trip over, they sure do take a beating back there in a big crash .

New rear end looks plenty strong to do the job , it is just that a lot of holes in that area can tend to crack after time with all the cycle loads, and flexing it constantly sees in that area . Less to do with strength and more to do with fatigue if you know what i mean .

Prolly be just fine , just keep an eye on it and if it starts to go, beef it up where it needs it , simple . Debbur and a slight chamfer on those holes may help .

Build on looking forward to updates.

Gotta love Ebay... Some bloke bought a brand new UTV and after offloading it from his trailer decided he wanted a set of super agressive mud tires (which is really smart for a place thats largely been in a drought for the past 20 years).

Got his old rubber... brand new except loading and unloading it for $150, they'd be closer to $600 new from a store. Here they are in my shed... winning!

One of the guys in our club just blew two beads and rolled. I think given how much the rebuild is costing me, spending the money on beadlocks is really preventative of a more expensive rebuild in the future. Now I'm looking for good deals, haha

Hey Ham - I see you guys are going on a heim buying spree - do you already have a source?

If not, give Compton Controls (http://www.comptoncontrols.com) in Ohio a shot. Talk to Ken III and tell him that Richard sent you (and tell Angie I said hi!).

Here I was next to a supply house for rod ends for the past 8 years and didn't find out he carries them until about 4 months ago.

Great people and I'll take a guess and say Ken will cut you a good price on a bunch of pieces.

Well, no progress on the build... but there has been some progress with parts. Have my new beadlocks:

And I was on gumtree the other day, and there was a titanium exhaust off a Kawasaki ZX9 for stupid cheap, so decided to go and have a look. I think it was a good buy for $50 as it will save a lot of weight, and hopefully sound pretty good. I'd prefer dual exhausts but the way I'm doing the new exhaust, 2-1-2 is going to be too difficult anyway.

EDIT:
Just put another tire on its rim. Put all the beadlock bolts in finger tight, then tightened them in 2-3 steps in a star pattern by hand. No rattle gun ever came near the wheels. 2 bolts stripped their thread. Very unhappy.

My options are to tap all the holes a size bigger. Its a big job with 64 holes but I think its the best option I checked and an M8 allen head screw fits in the countersink on the beadlock rim so I only need to modify the wheel not the beadlock ring.

The other options are to use one of those helicoil thread repair kits. It will be quicker but I have never used one before and I'm not sure how good they are.

third option I saw online was to use teflon plumbing tape to beef up the threads. I have never known of this as a trick but it could be worth a go as a quick solution. Not really a long term thing. Never heard of it and I'm a bit skeptical

Any thoughts? I'm pretty cheesed off at the moment... New toys breaking by themselves before I can break them is disappointing.

I know this has been up a while but thought I would respond anyway. I would helicoil the holes even if I made them bigger. Any bolt that gets beat like that and has to be taken out more than a couple times should be coiled.

Thanks Roy,

I think I figured the problem out... the stock bolts are a tad on the short side. They are 22mm with only 20mm threaded (and a stupid nobby bit on the end). They can take a 27mm thread without causing problems. When you go to tighten them initially, only 1-2 threads are engaged and they strip. I used longer bolts on the messed up holes and they grab just fine. I'll start by replacing all the bolts with longer ones (bought some nice stainless dome head capscrews) 25mm long (an extra 5 threads engaged before they start biting down) so hopefully that will fix and prevent further damage.

I'll let everyone know how it goes, as I still feel like drilling to bigger holes might be the right option

New rear end, pretty much all the fabrication is done, just need to paint and bolt it back together. If you look carefully you can see a starter motor in the rear end that will hopefully function as a reverse... Thats the plan anyway. The plate pivots forward and backwards to set chain tension, but it only goes about halfway back as the starter hits one of the diagonal bracing bars. I'll have to cut out the bar and run it slightly differently. The whole rear end must have been bent in the crash pretty bad - it looks crooked and it is really frustrating me, but the housing is within 1mm of centreline, and the sprocket is true to the engine which is all that matters. It just looks a bit dodgy

New exhaust, going with a 2-1 system. Not fully mounted, but I just did a quick test fire to see what she sounds like. I'm quite pleased, has a nice note. Can't wait to hear what it sounds like at 9000 rpm, :D I was able to re use the front header, but had to fabricate a new rear header and the collector. i ran out of U bends and ended up having to hack into the old dented header. It was a nightmare job but its together, and I think when I polish it up it should look pretty good.

New instalment:

I stripped the floors off, which were riveted on to do most of the rebuild. I welded a buch of lugs to the frame so I can bolt it back on rather than the rivets. Just more convenient. I thought whilst I was at it I'd do the same for the front bash plate. I stripped it off and found that the front suspension mount was bent, badly bent. Damn.

The blue box section there was as a straight edge. Prior to the crash, it would sit flush on the bar above it thats bent... shows how far out it was.

5 mins of grinding later and it was out.

I was lucky and there was not too much surrounding damage. I did have to add a doubling plate to where it attaches to the main frame, i welded it and it was just thin and flimsy, blew a few holes and thought it wasn't worth risking anything.
http://i336.photobucket.com/albums/n349/Hamish_Barracuda/20150124_131410.jpg (http://s336.photobucket.com/user/Hamish_Barracuda/media/20150124_131410.jpg.html)

I used some round bar to align the new suspension mount. Luckily the front mounts sprung back to the right alignment after I cut the bent bit out, and I only needed to replace the rear. The box I replaced has about a 3" long box telescoped inside it and the piece it joined onto. Hopefully it should make the join nice and strong.

And here is the finished result. Looks like its been replaced as its the only thing with a nice paint job on the whole buggy.

I am installing a starter motor reverse to the rebuild, and I had to move a bar at the rear to give clearance to the starter. It was very unsatisfying taking something that was aligned perfectly, cutting it out and replacing it with something that looks like a halfassed job. Anyway, its functional and it has to be that way. It just annoys my perfectionist approach to buggy building. It was one of those jobs that created problems. Had to move the tube for the starter motor to fit... then had to move the radiator mounts for the tube to fit. Hopefully thats the end of it.

Good job. looks like you really banana'd the whole frame! Sucks, but you've got the right idea, as long as all the suspension mounts are square you'll be good to go. makes you cross-eyed while doing the work and second guessing all the measurements.

If the starter motor doesn't cut it for reverse, think about using a winch. A member on another forum came up with the idea (I haven't seen it tossed out before) and with the gear reduction of a 2500 lb. winch, mating a one way bearing to a sprocket hub on the engine output with another sprocket where the winch spool is seems like a pretty cheap way to get a reverse capable of putting out plenty of torque.

Hambam

Making slow progress. Only got a half day on it today, and they were those jobs that you think takes 20 minutes but ends up taking 2 hours.

The engine usually had some difficulty starting when it was hot, and with another starter motor to crank for reverse, I thought I'd better get some more amps behind the start button.

I was deciding between a Lithium and a sealed battery. I was keen for the lithium but the charger was just as much as a new battery and I am trying to be good and save money. Besides, got a really good deal on a sealed gel battery with 450 cold cranking amps. Shouldn't have any trouble kicking anything over with that in the buggy.

Mounts were a bit of a pain to get done but they are in and its solid. In retrospect I should have mounted it an inch further forward so Its not so close to the engine but its looking pretty good none the less. I'm adding an isolator switch whilst I'm at it. There should have been one originally so its good motivation to get it done.

New vs Old

Hard to see but its hiding in there somewhere. Its mounted sideways! Thats the great thing about the Gel batteries... You can mount them any way you want. I was finding it very difficult to find something that would fit anywhere but when I realised I could mount it sideways, this one fits perfectly

Its a bad pic, in reality, there is about 3-1/2" clear between the two, and given that the engine is open and not in a hot engine bay, I wasn't going to worry about exhaust wrap, particularly as I heard it eats stainless headers compared to mild steel. I'm at work but I'll get a better pic to show the clearance tonight

Bloody long week just passed. I swapped to the night shift so I had the days to work on the buggy. Recon I got 4 hours sleep a night for 4 days.

Got it to the race with no brakes, no roof panel, the wrong wheels and tyres. I had help from some amazing mates with a 5 am start and I was ready to go for the first race at 10. My parents surprised me and quickly got drafted to helping out. Mum went and got some parts and my old man helped with the brakes, nerf bar, wiring and a few other things. Literally, everyone was suiting up and I just managed to throw my suit on in time and jump in the cockpit to go.

Bad news. My head was touching the roof. After I rolled it last time I wasn't taking chances. Managed to get the seat adjusted and was tightening the last bolt when the race started.

Made heat 2 as the shakedown run so I wasn't pushing too hard.

Heat 3, the gear shift broke.

Missed heat 4, and heat 5 the new diff had a shaft come out and it ended my day. Quite a crappy weekend all in all, but thats racing for you.

Like father like son:

Feel ya pain Hambam

Did you find the cause of the drive flange exit out of the diff?
Axle too short at droop ?

I only had this happen to me once with the BMW diff I was running , But I got a little out of shape and slid the buggy side ways into a Fence Strainer post , The impact dislodged the drive flange out of the retainer clip , drove for @ 5 K's on it till I hit a small jump , as the suspension drooped it pulled the drive flange out of the side gear
I was lucky just snapped the shaft back in and I was back in the race

Hambam
03-10-2015, 01:16 PM
Thats a pain mate, but glad yours was an easy fix. I probably could have popped it back in, but I thought it wasn't worth risking more damage. I was well out of the running to win by this stage, and after months of rebuild I didn't feel like risking more damage and more tool time. I need a break, haha.

Not sure exactly of a cause. I tested it at full droop prior to driving and everything went well with no binding, and it didn't pull the axle out then.

I do know that I tweaked the air shocks prior to the race it failed, raised the ride height. I'm guessing that it ran with more droop, and hence it has a lot to do with why it happened. Your probably right about the axle length. I will go through it all tomorrow, and really look at the good side still on the buggy to see if there is some reason I can find as to why it happened, so I can stop it from happening again.

Good points. I'm getting some stuff lasercut so I was just going to throw it in with the quote. They charge $5 per new part so I learned a few batches ago that if you're doing one-off parts they get expensive quickly. I'm going to put all the parts to this one in one file and join them with a few 5mm wide 'sprues'. cutting disk and 10 minutes should have it in its parts in no time. Going off previous orders, I doubt it will cost more than $80 for the whole thing to be cut... Could be quite wrong, but who knows.

I have tabbed the whole thing so it slots together like a jigsaw, and a few tack welds should hold the whole thing together for final welding.

I'm getting about 100 tabs cut to mount some body pannels on so the more you get the cheaper it becomes. hopefully it won't be too bad.

That clutch/brake pedal you found was a good deal. Wilwood make great stuff too! Very tempting...

I am indeed going the brake bias setup. The tabs on the top bolt on so you can flip the tube, raising the bias bar by 10mm. Should allow some adjustment in brake pressure and pedal travel without changing the master cylinders. Hoping I don't need to change much but I figured for the sake of a few bolts and a bit more CAD time it was worth it for the flexibility

Haha, that was the plan. My fab skills suck now that I realise how good lasercutting is. And for lots of parts, its well worth the price. The local laser guy with this order charged about 50 cents per weld on tab... I got 100, you can never have too many. the best part was that they are all identical, If you can't drill a hole though it, you can trace around, and centre the hole on another tab to drill the hole exactly where it should be. Worked wonders when I did the floor plate.

Heres a test one with a rivnut inserted. Pretty pleased how they came out... now to weld a 50 or 60 to the buggy for pannels... Joy. I have a pretty kickass paint job in my head though, just deciding which obnoxiously loud colour I'm going with. Fluro green, or road cone orange.

Thats a great idea for panel tabs. Fast, cheap, and effective. Wish I'd thought of it before getting this stuff cut.

I always thought laser was out of my reach, but I put a quote in for a few things that I absolutely couldn't make, and they were very reasonable. Since then, I do a couple of orders a year. Difficulty is in waiting for enough parts to build up to get it all cut... Usually I'm an impatient person.

Nice work, amazing how much stuff gets in the way of the shifter ... Why didn't you JUST weld a tube through your oil tank and give it a straight shot? :D:rolleyes::D

Fuel tank... And i was seriously considering it at one point, hahaha

Got it all hooked up and back together over the weekend. I finally got round to doing some panelling too... Its bright. Perhaps too bright, but then again I do like to make myself known in a crowd:

A member at our club has a cuda in what looks to be the very same color . I t looks pretty good .

When do you go for a drive / race ? Keen to hear what you think of the shifter over the cable , although i think i know the answer .

Kubota red Talon. Good thing is its cheap and standardised so I can get it at most tractor dealers australia wide, and also in rattle cans. Makes touch ups and repairs nice and easy.

Have a race on saturday/sunday, so hopefully it goes well. I was able to leave the old cable in so that if its a disaster I can swap it back to the old system in a few minutes.

Problem is that everything else is untested so I"m hoping that i survive the weekend OK.

Thanks K Fab. I think there are about 6 of us in my division. Short course race, laps about 2km. Usually run a few laps per heat, hopefully get 10-12 heats in over saturday and sunday.

Historically, if you finish all races, you will place, and I really want some silverware. Just have to hope all the changes and repairs hold up for this one!

Race report:

So to start off with, there IS footage, BUT, it turns out my new $18 cameras only work when they are fully charged, and where a bit tempremental (its what you get for not paying for a full price gopro). I'll upload it later on over the week.


In our class "superlites", there were 6 buggies.

4x hayabusa powered Barracuda's (one a double seater)
1x R1 powered Barracuda
and me... the VTR-SP1 Barracuda

It had been raining for a couple of days, so the track was pretty muddy. There were other classes that included the polaris/canam ATV's, as well as 4x4's. We were the only buggy class. There was also a race between fords and holden RWD's road cars (for the americans out there, holdens are an aussie car brand... mostly rebranded GM's, but there is an aussie designed and made saloon called a commodore. Also, the Holden Monaro got rebadged in the states as the pontiac GTO... thats right, its an aussie design)

Unfortunately the double seater blew his engine in the first race. Literally, there is a big hole in the side and conrod pieces on the engine bay floor. Ouch


I could hang in with everyone but had a lot of trouble finding the acceleration to overtake. This is where having 40-70 less hp than the other guys really showed. It was muddy and unforgiving. Had to take the lines with the most traction, but if you pushed a bit too hard you would just push out wide in the mud, loose traction, and a few seconds. Good fun but was getting a bit annoying by the end of the day.

Still, managed to keep my own. It was raining lightly and intermittently all day and the track got rutted up pretty bad. It was doing havoc with all our class. Of the remaining buggies, everyone without a beadlock blew at least one bead on the first day. Glad to have my beadlocks on saturday. The guy who was putting down the fastest times went over a jump and broke his steering wheel of.... the wheel snapped off the spokes. We couldn't believe it. Shows how important quality parts are.

By the end of saturday only me and one other had managed to finish all races. He had blown a bead halfway through the last lap and pushed on. Got him the finish, but added a minute or so to his time. Left it open to me so long as I didn't screw up.

Here is the buggy at the end of the first day:

Sunday, all I had to do was hold on and finish to keep the lead, and thats what I did. It was stupidly muddy though. The suspension sagged over 2" from the weight of all the mud that got stuck to its side.

4 races on sunday, and after the first 2, I noticed one of my rear tires was flat. Turns out the beadlock ring had worked loose. two bolts were stripped, and after I fixed it... did it again in race 3. Now has 4 constructive stripped threads, so will need some repairs. Made driving in foot deep mud with one good drive wheel a demanding task.

Managed to hold on, even with this over your helmet visor:

So the result overall....

I won! Woo hoooo. First race meet win, I'm very happy.

I'll post some more pics and video later, but right now, I'm spent and its bed time

Nice job Ham , gotta be happy with that .

How were your times compared to the other classes ?


Not sure about the times... they haven't been released (yeah, I agree, sounds a bit weird), and I wasn't measuring them. Last round a good time was 1:30/lap, but they changed the course so there is a U bend in the rear straight, and there was a lot of mud, so I think I was over 2 mins on average.

Last round, the buggy class would have been the fastest class on average, but there were a few racing 4x4 builds that were slightly quicker. I think the one that won it was a King of the Hammers buggy imported from the states, heard it was well over the $200,000 mark to get it to where it was.... so pretty good that our cheap little bike powered buggies managed to put some of the more expensive builds to shame.

This week though, no one had traction, so I wouldn't be surprised if we were a bit slower than the 4x4's. I'll let you know when I know more.

Heres a tease. you-toob is taking hours to upload everything, but there are only about 4 good vids anyway.

https://youtu.be/1sHLCuHINgU

**EDIT**
Got another vid uploaded. good bit starts at about 3 mins so may as well skip to there
https://youtu.be/ITENuHz501c

Pretty funny on the run in the link above. It was so wet no one knew what was hapenning. One of the guys thought he had a flat and pulled over to ask a marshal if he had "rolled a bead".... apparently yelling "rolled" and pointing at the back tire is a bad idea on a racetrack, so a red flag was pulled and we had to rerun the race. Whole thing took so long that it killed my camera battery and didn't end up getting much more footage other than this. The front camera was pretty much mudded over after the first straight too, so not much there either.



How was the new shifter ?

Challenging. It shifts way better! but I swapped the way it was shifting, used to be back was down, forward was up... now its the other way. I knew I was doing it when I made the linkage. I did it on purpose as it always felt wrong the old way. I kept changing the wrong direction though (usually when I wanted to down shift) and it was a bit frustrating. Very happy with the shifts though. Its like butter compared to the old one.

Wish the weather gods got that news over the weekend. At least it kept the dust down. Mind you, had to drive with the visor up a few times and copped some mud to the eye. Still very red and painful. Worth it though :D

Yea some of the autocross rounds we have done it is hard to knock off the fast 4WD cars, especially on those gravel AC tracks .

Good to hear , i thought you would like it .
My first car was the same forward was up shift , just kinda made more sense [ to me anyway ] just slap it forward with the open hand . So i am kind of stuck with it now , i would struggle if i jumped ship . I know a lot of guys prefer it the way you have yours.

Looks great man! Especially since the shifter is now moving the proper way! If you ever get the chance to drive a serious road car, you'll quickly see why you push forward to downshift. With the braking and acceleration forces they can generate, you definitely want the shifter to move in the way of the g forces.

Super fast road cars aside , my original thinking [flawed as it may be ] was to put more emphasis on fast up shifts , ie hand off the wheel and and hit it forward all in one movement without even needing to actually grab it .

Reaching forward and actually grabing it and pull back for an upshift is two distinct actions for an upward gear change. That was the theory anyway .

You need to actually worry about putting your shifter on the correct side of the car for a start .:D

Spent the day today stripping the beadlocks, drilling the 16 holes in each wheel out to M8 from M6. Tapped with taper then plug tap, and drilled the beadlock rings out. After stripping the threads on the beadlocks once, I didn't want to take chances, so I threaded all the holes by hand. Long bloody job but its done now, and I'm happy with the result. Just gotta wait for the right bolts to arrive in the mail.

Any advice for assembly? I was going with blue loctite and not sure about running a spring washer.

Just anti seize them and torque to 12-14 inch pounds. Not sure what Newton meters that is.
No need for loctite.

06-27-2015, 08:41 PM
I forgot to add that I always run a flat washer under the bolt head.
I run a pattern too, using a 1/4 drive Makita impact. Zip bolt down to a couple of quick ratchet noises, skip two bolts, zip next down. Run that pattern until the beadlock is fairly tight. Then go in with the little torque wrench and finish, running same pattern. Usually takes three rounds to get it torqued properly.

Do enough of the darned things and you'll get a feel for the impact amount. Drops the torque wrench time down significantly..

Hambam
06-27-2015, 10:49 PM
Thanks guys. I was going to go with the helicoils, but opted to drill every hole out to a bigger size instead of repairing just a few. There wasn't a whole lot of meat around the holes in the rim and I didn't want to go drilling a bigger hole to fit a helicoil. I figured it would be stronger this way.

The heads of the bolts are recessed into the beadlock ring. A socket head screw fits perfectly in there, but not sure if theres room for a washer. Might have to hit the beadlock rim with an end mill and open up the holes to fit a washer down.

I'll tighten them in the order you suggest K fab. Think thats why i ended up stripping the threads in the first place

Keenserts are the way to go. Stronger than helicoils and if you damage one just drill it out and replace it.
Only problem is m5 requires an m8 tapped hole and a m6 requires a m10 tapped hole.

I looked at the keenserts. They are pretty awesome. They also cost a hell of a lot. I really wanted all the bolts on all the wheels to be the same, so just drilled them all out to M8. It took about 2 hours/wheel to drill and tap the 16 holes on each rim. but now they bolt up well and I feel they are a lot stronger.

The V2 is an awesome engine, Very happy with it!

I haven't got the reverse installed at the moment. I had problems with the rear end and stripped it. Never installed reverse afterwards - its a job for a rainy day.

Hey, just had a quick look through this thread and it is all looking good, loved the race report you did with an awesome outcome! i also have a Barracuda, but still in the trial phase. having major problems with the chain, if you could have a look at my thread and possibly voice any ideas that may help me that would be great!

Basically i am running a heavy duty drag chain but still managing to bend pins, we manged to get it running without stretching on a 17 tooth and 60 tooth sprockets. but i found this very boggy through the gearing, tried a 15 tooth on the front as i couldnt get the 16 on and was back to bending the pins again.

any help appreciated thanks Matt

SO i finally caught up with a few of the other local boys now I've moved interstate. Work has been killing me this year and every weekend off I've had I have had someone getting married and weddings.

Anyway, we had a test day at the local offroad racing track. This track is awesome, more of a tight technical track than a high speed run, and it had been raining all night so it kept the dust well controlled. Didn't get out of second for most of it
I had some video, but it was corrupted and didn't save. Joys of a $40 fake gopro.

Simon (also on the forum) managed to get some great shots (hope you don't mind that I ripped them from facebook)

So then my fun ended. I was pushing wide into a corner trying to come out shallow. I was concentrating on the narrow line, looked ahead and it was too late. Boom. Tree. The tree won. No magic tales, I screwed up good. My fault. stupid.
Damage report so far is:
Tie rod steering box arm
Upper suspension mount
Upper and lower suspension arms
Air shock.
