View Full Version : ProtoLite SS 1000-new 2 seat build

05-24-2010, 03:27 PM
Allright, time to start a build log for this one.

This is our new 2 seat design. Very similar to the 1st one , only on the 1st one we left plenty of room, in width & height.

This roll cage is about 6-8" narrower, and the top is chopped a couple of inches.

The rear engine cradle is the same as the last single seat race buggy I just finished.
New Page 1 (http://www.protodie.com/DXT%201000.htm)

We have always made them removable on our buggies, but now the single seaters, and the 2 seaters will have an identical engine cradle mounts.
The mounts are also the same for a live axle cradle, so if we build one without reverse,,,,you can always roll a new engine cradle in later,,,,with reverse.

Overall length is 120"
Width is 70-72" outside of tires
wheel base is 94 3/4"
Should weigh in at right around 1000-1050 lbs

Front travel is 18-19"
Rear is 14-15"

Fox 2.0 air shock 10" travel all the way around

This is going to be my own personal car again,,,and my Goal is to be done by July

few more,,,and the start of the real world chassis

05-24-2010, 03:39 PM
few more then back to work

Oh,,,,,,the shop may show a little messier than previous builds,,,,,,,I am on a mission.:D

05-24-2010, 03:44 PM
And to think how clean your shop is compared to mine lol.

05-24-2010, 07:16 PM
Oh there are days my shop could compete with some of the dirtiest.

Time to live on the edge & even the tan,,,,,,,,,,welding in shorts is always fun

05-24-2010, 07:17 PM
You always do nice work, i will be following the build keep the pic's coming

05-24-2010, 08:43 PM
Thanks Jerry ,,,I do my best

I got the main rear section on tonight,,,went pretty good.

The rollcage was heavy tack welded on the jig while assembled.

I went thru and welded 70% of the the tubes, so I can pull it off the jig.

Tomorrow I will pull it off & we will put it in our "twirly Jig"

(We make up names for everything)

This lets us rotate the rollcage, and lock it into position to make all the awkward welds easy.

Laser is ordered, and will be ready at the end of the week.

05-24-2010, 08:44 PM
one more

05-24-2010, 09:11 PM
Yer, an animal....Looks killer!


05-25-2010, 06:27 AM
Thanks Justin,

I decided to wait until after I get laser to pull it off the jig table.

This way I can build the engine cradle, and weld in all the mounts right on the jig.

That means I will go to steering, seat mounts, and make a few A arms instead.

Looks great, I love the look and design of your cars. Can't wait to see some video of it tearing it up!!:)

05-25-2010, 12:38 PM
Thanks alot,,,,,I am looking forward to make some video with this one.

I just got my seats, calipers, window nets, master cylinders, brake lines,,,etc,etc......

I will mount the seats 1st , then steering.

05-25-2010, 03:51 PM
looking great so far!
cant wait to see it running

05-26-2010, 09:33 PM
Allright,,,,,things are rolling good.

seats are mounted. I use 1 5/8 Unistrut, so that the seats can be adjusted,,,then locked down.
Much stronger than seat sliders, but take a few minutes to adjust.

Wilwood brake / clutch pedal assembly is in,,,gas pedal, as is the steering with a quick disconnect.

I must say,,I am very happy with the fit & feel of all the pedals, steering wheel and seat.

The other cars have been very good & comfortable, but the little things I changed from other builds makes this one feel great & fit like an almost worn out work glove,,,,perfect.

05-26-2010, 09:36 PM
few more

05-27-2010, 05:23 AM
Wow what a good and fast progress you make in a couple of days!:eek:
Great build to follow, thanks for all the pictures.. :D You already catch up my build wich now takes a year:p But you can't compare those two builds because you are a buggy guru, and i'm a buggy dummy:cool:

Have fun and good luck with your build! I will follow it with pleasure:D

05-27-2010, 05:12 PM
Thanks, for the kind words.

Every build gets faster & easier,,,for most everyone

While it looks fast, I spend MANY hours engineering & designing before the build so that when it is time ,,,all the problems are worked out, parts are sourced and I just need to grab numbers & prints and build it.

Years back,,the builds took alot longer because we were sourcing parts, designing,,,,,testing,,,,,debating,,,,changing our mind,,,sourcing parts,,,designing,,,testing,,,,the endless cycle.

Now many of the parts we designed and make,,so I can get them off the shelf instead of waiting a few weeks.

05-27-2010, 06:08 PM
Beautiful as usual..

Like the use of the Heim for the steering column support.

Are you going to add any sort of V or diagonal brace behind the seating area? That's the only thing that catches my eye as something for you to consider (something to resist lateral loads a bit more).

Very nice!!

05-27-2010, 06:57 PM
That is a 5/8 heims, and you have to turn the tubing down just a touch.
This lets you adjust the point if needed.

I have a bunch of tubes I am adding yet,,,,especially side bracing.

Not sure which area you are refering to, but the thing to remember is we are and have been using 1 1/2" dia tubing, and not 1 1/4"

I have taken some of the early cars for sprint car tumbles and they always prove over built.

05-27-2010, 09:27 PM
I would like to see what you come up with for a offroad stadium lite type racer.Your buggies are great i'm just curious as to how they would do on a off road track like Lake Elsinore etc...With good size jumps etc,,I have watched the video and they are very fast and I would love to drive one and it may just be me but some look a little low for an offroad track???

05-27-2010, 10:59 PM
On the roll bar, I was just looking at the area behind the seat up top.

05-28-2010, 07:09 AM
Sure,,back there.
yes I do 100% agree that would be even stronger.
If I were to add more bracing in that area, I would need to angle back further, to keep proper head clearance.

The structure with ajoining tubes as is is stronger than the data you used of just the one tube.

Not looking to debate engineering , strength & saftey, because no matter what you build, someone will tell you to build it stronger.

I am 120% confident in the strength of our designs , from hitting trees, rolling, flipping,stuffing the nose jumping,,, and hitting other cars.


Hopefully a local track will build us an off road track this year.
They are talking about it ,,,but we will see.
Bobs family raceway,,the track we race for years is closed,,,,so after this car is done,,we are going to try & push harder to get an offroad track.

The single seat travel is 15-16" front travel and 14-15" rear travel.
910lbs with a 1000cc and RPM gear box
70-72" wide and 114" long
If racing were do pick up, I could get this below 875 lbs if needed.

The 2 seat is 18-19" front travel and 14-15" rear travel.
The 1st version was 1100lbs but this new one is narrower and I expect to be a touch lighter.
70-72" wide and 120" long

We have always built to race 1st and go to the dunes 2nd so hopefully we get a new track home soon.

We have raced the single & 2 seat against each other last year, and we were supprised to see how close they are on the track.
So our goal is to race them together in 1 class that fits in a "box"
72" wide x 120" long

Most of the pictures you see are us set up for racing,,,and low is faster.
I prefer to only set up the car as high as needed for conditions.

here is a pic of one my biggest jumps caught on camera,,I only wish we had it on video that day.

05-28-2010, 07:48 AM
here is a pic of one my biggest jumps caught on camera,,I only wish we had it on video that day.

Wow, now that's some air time...[smilie=jumping.gif]

What size paddle tires do you like best for the 600 cars? I'm still trying to figure out what to use...

05-28-2010, 02:41 PM
Those were 21" dia and kinda small but worked well.

Now I am running all 25" tires on 12" wheels.
But this is with 1000cc motors and RPM gear box.

I actually find that regular dirt tires do awesome in the dunes.
Unless I am drag racing, they work great.
Half of our last video was with dirt tires on.
The section of video on the hi banked dune was with dirt tires,,,,the flatter drag strip area was with 26" ITP Dunestar paddles


06-04-2010, 10:50 PM
OK,after all these years,,,,,,,,,,,,,

somebody please tell me how to upload pics to where they are not small thumbnails.
I see plenty of great posts with full pics,,,that do not need to be "clicked"

I am finally the guy at the gas station asking for directions:o
but at least its not cause my wife made me,,,,,,,,this time

06-04-2010, 11:00 PM
Click the red circled button:

Then link to a photo that has been uploaded to another server somewhere: your own website, Picasa, Photobucket, etc.

Good Luck!


06-05-2010, 01:29 AM
Protodie, I have just read this thread and I have always liked the design of your cars. They are some of the coolest looking cars around. Just one question, it's probably been asked before, but are you going to sell plans for this or is it just for your own personal use.

06-05-2010, 07:32 AM

Thanks for the info. here is my 1st test

06-05-2010, 07:40 AM
Sweet sucess alright

Yes, I have been planning on releasing plans for others to build.

The single seat plans and prints are 90% ready

This is on hold for now while we are developing the new 2 seater and some other stuff.

06-05-2010, 07:51 AM
I call dibbs on the first single seat set!!:p

06-05-2010, 10:20 AM
Thanks, it will be worth the wait. I have only been gearing up for building a buggy for about 3 or 4 years now (but life keeps getting in the way) so a little longer won't hurt. I have some plans of my own drawn up in bendtech, but I realy like the style of yours.
Is the two seater going to use atv wheels and tires as well.

06-05-2010, 09:36 PM
It will have 12" ITP bead locks on it,,,same as the single seat DXT.
4 on 110

We have hubs with 5 bolt automotive patterns on them now too.

3 patterns 5 on 4.5 5 on 4.75 and 5 on 5

so we can run what ever wheel we want.

too much $$ aluminum in a hub to set up for a wide 5 pattern though.

progress has slowed for a couple of days.
Like Stomper said, life gets in the way sometimes.

goal is to have it as a roller on wheels next week. Should not be a problem as long as my shocks show up ontime.....

it has been taking 5 weeks to get my Fox shock orders:confused:

certain parts are ordered even before tubing to make sure I get them on time.

06-08-2010, 10:29 PM
What is the size of your engine compartment, from the very front of it to the center of the rear axle. I am working on a project right now for using a sled engine with the chain case, for reverse. It will be similar to minibajamans set up but will have the chain case and rear axle built as one unit that will just bolt in for easy removal for maintenance. I am just wondering if it would fit into your frame.

06-09-2010, 07:29 PM
about 28" from center of axle to the front / or firewall

just got my shocks & new motor,,,,oh happy day:)

Hope to have it a roller tomorrow.

26 days into the build. Goal is to be done is 36 days or less:eek:

back to work, and I hope to post pics tomorrow

06-10-2010, 09:24 PM
Allright,,,,,she's a roller

19" travel front and 14" rear

06-10-2010, 10:21 PM
Are you going to make a trip out west with this?? Or at least Idaho.

06-11-2010, 06:54 AM
I sure hope so.

It takes the perfect mythical balance of time,money, enough work,,,,,but not too much work.

But I hope so

06-11-2010, 08:46 AM
Wow that thing looks amazing!:eek:


I wish I had the means, money, skills, time and space to build something like this:(

06-11-2010, 11:41 AM
I am curious? I have done some reading in the forums and have seen the debate about equal and unequal length A-arms. I have also done alot of reading in some books I bought. It is hard to tell from the pics but it looks as though you are using equal length A-arms in the front? Is that right? if so why what makes you go that route :confused:

06-11-2010, 12:03 PM
The fronts are unequal length

4.4 degrees of total camber change over 19" of travel
or 3.9 degrees from ride to comp , or bump
and .5 degrees from ride to droop

The rears are equal length, and you can get your camber gain by where you mount at the chassis

on the rear camber changes 1.8 degrees from ride to droop and 3 degrees from ride to comp, or bump

the reason I designed equal length on the rear is so that all 4 A arms are identical.
1 jig, and easy to keep spares with you when we head to the track,,,or dunes

06-11-2010, 09:15 PM
That is looking GREAT Justin. The clearance is awesome.

06-12-2010, 06:39 PM
:eek:That thing is sweet!!

very nice!

06-15-2010, 11:24 AM
Wow that has to be one of the best looking buggys out there. Nice work.

That really cool how you made the engine and rear axle a bolt on sub frame. I have been trying to figure something out so that evrything would bolt into a frame that was already there, but to do it your way would be alot easier. Do you get any flex with that system under hard use. I am assuming that your single seaters are like that also.

06-15-2010, 01:56 PM
Thanks for the kind words guys.

I 1st designed this type of engine cradle for motorcycle engines back in 2003 / 2004 on our 1st MC powered buggies.

(before that it was snowmobile engines and swing arms)

every MC engine buggy since has had this type of engine cradle.

We found a little flex in the 1st couple, mostly from some hard hits and bottoming the frame jumping,,,,,,,,which you should not do.

We changed / improved the design accordingly over the years to resolve any minor issues and continue to improve performance & ease of build.

06-15-2010, 02:52 PM
What is the thickness of your plate work for that mounting system. I was thinking of using 1/8th material to save weight but am leaning towards 3/16 instead for strength.

06-15-2010, 02:56 PM
80% of all our plate work is 1/4" thick.
for sure all of the engine cradle. I design cutouts to reduce weight where I can.

a few areas of low stress are 3/16 in the build

06-16-2010, 02:09 PM
Can't wait to buy some plans for that rear end from you (wink, wink... hint, hint) :D

06-16-2010, 04:18 PM
why buy plans when you can just get the engine cradle complete, ready to bolt in,,,,,,hint,hint,,wink,,wink:D

live axle or Rpm engine cradles.
Start with a live axle cradle and 2 years later when you want reverse,,,,,unbolt the live axle cradle & bolt in the RPM cradle without having to rework your rollcage:eek:

06-16-2010, 04:24 PM
...and sell the live axle one on here to some other poor guy who is starting his own build!

06-16-2010, 09:09 PM
great idea,,,recycling at it's best:)

I like to build things myself in order to keep the costs low, but if the price is right I would consider buying a cradle. Do you make one for a GSX 750? PM me please.

06-18-2010, 08:09 AM
Daaboots,,,PM sent

work on this has slowed,,,,cause other work is busy,,,which is good.


Kirkey racing seats
G force cam lock racing harnesses


Gear shifter is on right side for this one.
I designed the shifter to go straight thru the dash / console to hide some of the linkage.
It is right off the wheel rally style, and shifts smooth.
console will be covered with aluminum later.

RPM Reverse shifter is below, right between the seats.
This is a push button locking lever shifter I designed

Radiators are mounted,,,but not shown in pics

back to work,,,,[smilie=gun_chair.g:

06-18-2010, 11:57 PM
Looking Good, keep em coming.
Smooth as usual.

Quick short post,,,with no pics,,,sorry.

Chassis and body panels are coming back from powdercoat this afternoon.

I am working,,,non-stop to get this done next week. So there will be a ton of pics later,,,,,,,just no time to upload them now

I need a vacation after this is done.

Good luck this last week and i'm also looking forward to the photo's!

You make sure that you have fun with the build.. that's also véry important!


07-15-2010, 07:14 AM
LOOOOOONG days of hard work,,,,and still going.

Finishing today,,,and dunes tomorrow for testing:)

Shop is trashed from the mad build but we will clean next week

Here are some pics of the new 2 seat ProtoLite SS1000

More pic to come in a few days,,,as I will be gone for the weekend

07-15-2010, 07:17 AM
It has been 1 1/2 years since I sold my buggy,,,,,,so I am very glad to have my own again:D

Couple more pics

The new shifting system looks awesome! How is it handling? Or haven't you ride it around the shop yet?

Have fun tomorrow!

07-18-2010, 06:15 PM
Car performed flawlessly in the dunes on Friday:D

Well worth the long hours over the last few weeks.

The panels are powder coated aluminum
Black with halographic flake,,,so it changes colors in the light

All the action photos are on someone elses camera,,,so I will post those another time.

Here are some still pics from Silver lake

That thing shreds sand!

How do you like more POWER?

07-21-2010, 12:02 PM
More power,

I don't like it,,,,,,,,,,,,,,,,,,,I LOVE IT

More torque makes all the gear ranges more usable

These tires did real good, but I will be getting some paddles down the road.

I have always liked those tires thought they would make a great track tire

07-22-2010, 07:47 PM
They are, and pretty universal in other areas too (plus they look cool)

They are quite a bit heavier than some other tires we run though.

8-10 lbs per tire heavier

I received some better action photos from last week,,,here they are







07-22-2010, 07:52 PM
OK,,,,did it wrong agian,,,only got the thumb nails

forgot to mention our 1st generation 2 seater # 31 is also rockin the sand






07-23-2010, 01:41 AM

07-23-2010, 10:26 AM
Have you ever thought about removing the red section of the 1 piece tube, extending the green tube up, and then attaching the side tubes to it? It would drop a little weight, but more importantly it would get rid of the 2 tubes being ran right against each other, that has to be a pain in the butt to weld together?

07-23-2010, 10:52 AM
Wow, she sure likes to spit sand out the back end:D looks like fun. Now for the important question, WHEN ARE THE PLANS AVAILABLE?:rolleyes:

07-23-2010, 01:28 PM
Thanks for your input,
That part is actually pretty easy though.
Set height in the jig with the lower hoop, then set upper hoop on top, clamp & weld the inside.
Every cross tube or hoop is scribed with a center line also, to which I make sure all the center lines match by laser.
We have been building this 2 hoop design since our 1st snomobile powered buggies, and has been on every buggy,,so I may keep it the same.

plans are on hold indefinitley,,,which is a shame because I have the single seat plans about ready for release.
I will make a final decision by the end of the year hopefully.
Lawyers highly do not recomend......:(
A few short answers why,,,,

Product quality control, and our company name attached.
Liability,,,,without quality control.

Copywrite protection of the plans.
I see other plans copied, traded ,changed, and parts reproduced at production volumes for sale by people other than the original designer.

It could be good for everybody elese,,,but bad for us which is a bummer.

for these concerns, the cheapest alternative we can offer would be a rolling chassis, for the home builder to complete.
Then they can finish in their own time frame & according to their budget.
Parts will all interchange & fit, because they are jig built from the same jig.

07-23-2010, 10:06 PM
Sorry to hear that:(
BTW I like the double tube in the back. It's different and it's your trademark. I would keep it too!

07-23-2010, 11:49 PM
Wow now that looks awesome! Great photo shoot!

Nice you did an amazing job. Sweet!

07-24-2010, 08:42 AM
Thanks Guys

Stomper, yes I agree with keeping our style / signature design.

They are differnet than most,,some like,,,,,some like not

I do appreciate the input though

07-25-2010, 01:45 PM
[QUOTE=ProtoDie;194340]They are, and pretty universal in other areas too (plus they look cool)

is some of that weight in the rims as well? or are you just talking tire weight?

07-26-2010, 06:23 AM
Just tires.
I checked my notes for actual and it is a little less.

rear tires are 8 lbs heavier, and fronts are 5 lbs heavier

This is with the same wheels

total differnce of the 4 tires is 26 lbs to the car

08-01-2010, 02:37 PM
Heading to Silver Lake this coming Wednesday :)

Family day,,,can't wait.

My kids have never been to the sand dunes ,,,ever.
So this should be pretty fun taking them thru the dunes for the 1st time in the new 2 seater.

Brother and his family,,,and a couple of others are meeting up for a day at the beach/^^^^dunes

I like to go mid week when it is not so busy.

If anybody is going to be there,,,look us up

Hope to get e little more video and pics...........or I may just enjoy the day.

Dabiggs is letting me try some 26" scat trac paddles on the car to see how they work,,and if I like them,,,,very cool Thanks Dabiggs

08-01-2010, 09:20 PM
Great looking pair of machines, fantastic work, Have fun with the family.

08-02-2010, 07:09 AM
I was up there on Friday afternoon and was a Kind of suprised at how many people were there...it did thin out a little bit later on towards the evening though. Even saw a few MC powered machines up there...

No problem on the use of the paddles Jody.....can't wait to see how they work on your machine! I just checked with my boss, and he let me have Wednesday off, so it looks like my son and I will be up there also.[smilie=ecstatic.gi:

Absolutley awesome day in the dunes last Wednesday.

Mid 80's slightly overcast and Lake Michigan was in the mid 70's

Buggy had zero issues or problems .
It was worked hard all day and I was pushing the limits [smilie=ecstatic.gi:

I took at least 12 different people for rides thru out the day,,,and some got 2-3 rides.

I burned thru 3 tanks of fuel

Paddle tires I borrowed from dbiggs were great.

They are 26" dia scat trak taller hallers with 20 paddles.

I need to get me a set of these.

We were having too much fun to get an action photos though:(
But that's OK,,,it was a great day and the kids loved it.

08-06-2010, 08:44 AM
Glad your kids had fun! I had an awesome day up there with my son as well, think he had perma-grin all day long...

I have to say your machine looks even better in person!! And looked rather mean with those paddles on there ;)

Thanks again for the ride...and showing what pushing the limits means... :eek:...lol...I had a blast!

08-26-2010, 09:10 PM
Your paddles are awesome,,,,,and I will be getting some just like them.

Went thru a few tanks of gas with the buggy in the dunes again,,,,,,,what a blast.

Wife & kids love having a 2 seater now.

The sand drag strip was flat enough to hit 5th gear,,wide open:eek:

We were screamin,,,,,and then we did it 20 more times:D

pics are kinda blurry, but we were lifting the front a lot thru out the day.

Car handled awesome, and only had to adjust the chain once thru out the day,,,,took less than 2 minutes with the engine cradle set up.

08-26-2010, 09:50 PM
hi new to the mini buggy world, bought the plans for the cheetah and moving along pretty good. would ya happen to have any tips on the rear center carrier.

08-27-2010, 06:56 AM
Welcome to MBN and the the madness

Did the Cheetah plans recomend a drive train, or give instructions where to buy?

I am not familiar with how the rear is set up on the Cheetah,,but I can show you what we do, and has worked for years.

Here is a link to the live axle we use
The ProtoDie 930 C (http://www.protodie.com/930%20center%20drive%20kit.htm)

This can be welded right to the chassis, and add a tensioner.

We weld it into a removable engine cradle on our buggies.
Then the chain tensioner is a rigid mounted, yet adjustable idler sprocket.
With dual arms in the rear, we need this idler sprocket to direct the chain around the A arm mounts and into the sprocket cover.
When the chain starts to get loose, we shim it up more with washers, and tighten back down.

I will attach some pics showing this in our engine cradle set up.
This engine cradle has the same mounts as the one using the RPM reverse gear box. So engine cradles coule be swapped out for reverse down the road.

08-27-2010, 06:50 PM
ya the cheetah calls for pretty much the same thing that you use on the buggies from your site. way cool buggies man. im just so new and inexperienced that i dont know if your saft would work for my application. my plans show how i can make the shaft and its a 40 tooth spline for using 091 to 930 drive flanges.

08-27-2010, 07:10 PM
Ours are set up for 930's also.
You should start a build thread on your cheetah build.

Not sure if one has been done here yet,,,(could be wrong)
But post pics of your build and if you have any questions,,post them and many will help you with the solution,
That is what MBN is about.
Looking forward to seeing more of your build

08-28-2010, 03:44 PM
thanks for the info. ill try that.

09-04-2010, 05:57 PM
Hey Nice Build planing on making one myself.

just wondering if you have any plans or software you can give me a link to as im new to the mechanical world and cand do any of it my self [smilie=wink.gif] [smilie=bs_help.gif].

I Dont have much spare cash but i picked up two 1800cc car engines ($150 for two) and wonder if they would be good for one of this type of buggy [smilie=ecstatic.gi: or is that just overkill [smilie=thumbs_down: A friend of mine is trying to sell me a 250cc quad and he says that a quad is everything you need wheels, breaks, two of the A arm shock absorbers an engine and pretty much but at $850 its a bit overpriced for a 250cc [smilie=gun_bash.gi:.

Please help I apreciate it

09-05-2010, 12:51 PM
Thanks Henry,

We use all motor cycle engines, so I can't really advise on the car engines.

As far as the quad,,,others have used quad parts on a budget.

It may depend on how big or heavy you build as a buggy can be 4 times a heavy as a quad,,,and if it is a 2 seater,,then there is also more weight.

IMO: quad parts are for quads and would not hold up to the abuse of how I drive

I tend to build heavy duty and personally would not trust quad parts,,,,at 80 plus mph

09-07-2010, 07:54 PM
Well tried to embed a youtube video,,,,,could not get it to work.

so here is a link


or try here,,,but it takes a while to load


just some clips put together of the new 2 seater,,,but nothin too crazy.

Video was shot 1st thing in the day,,,,,,crazy came later and then of course we were not video taping,,,oh well

09-07-2010, 08:02 PM
Huh,,,,,now it worked

09-07-2010, 08:16 PM
Told you those tires threw the sand!! :D

09-08-2010, 10:48 AM
Ya you sure did:)

Let me know if you still want to come out to the shop and I will have them ready.
Other wise I can bring them back to also.

I appreciate you letting me use them

09-08-2010, 11:46 AM
Yeah, I would really like to stop out there and see the shop yet...been a busy few weeks here. I will try to make it down there middle of next week (Wednesday or Thursday) to grab them.

09-08-2010, 01:13 PM
Sounds good

11-30-2010, 10:25 AM
love the cars and your products. i am looking at using a set of your front hub set ups to modify my ridge runner when i get back from deployment next fall. but i am also wanting to get into racing. right now the front runner is a Polaris rzr. how do your buggies hold up to motocross type tracks? are they built for open hi speed sweeping tracks? How well do they hold up to desert abuse and mx style driving. I drive hard and aggressive.i would something like your buggy if it would hold up. What made you decide to go with fox air shocks? i have them on my RR and hate them. Far to soft for the aggressive driving and jumping i do. I have finally given up on trying to make them work for me. Now i just run them as is. They are fine for medium pace driving and slow technical stuff. But i prefer to drive it foot to the floor and hang on. bouncing in the dunes after jumping is a normal occurrence. So i am gonna switch to coil over shocks when i get home. just curious if you have tried them or why you choose fox air shocks. thanks for your time and keep the AWSOME work. i would trade my RR for your 2 seater any day especially since my buggy only sees dunes primarily any more. the occasional desert ride. but any more when it is hot in the summer i am on the lake.

11-30-2010, 01:27 PM
Thanks for the kind words,

When it comes to tracks,,,it is quite dependant on how the jumps are set up.

If they are short approaches set up for quads & motorcyles then buggies will all tend to nose dive.
The approach should be 1 1/2 to 2 times the wheel base of the buggy to not kick the rear end up in the air.

Now, given the proper jump, they fly quite nice, and land real smooth


We are very happy with Fox 2.0 air shox when tuned properly.

Factory settings are 40/60 and we run 90/110 and max out the oil.
This is much more stable for our setup.

I still like how quickly I can change a setup at the track with air shox.

If I do switch over some day,,,I am looking at the 2.0 air shox with coil overs,,,,,,,,,,This way I can still make slight quick changes .

My #17 Protolite SS1000 is tearing up the dunes of Qatar now.

Customer sent me some pics,,,thought I would share





01-12-2011, 09:40 AM
Nice pics.. wow so very cool..
Great info about the shocks also.. good to know for those of us thinking of using them.

01-12-2011, 10:43 AM
Cool pics Protodie!

Congratulations on your buggy and business success.

01-12-2011, 11:44 AM
Great photos! What a nice machine. Any issues with the RPM and the chain?

01-12-2011, 12:15 PM
Nice Roost!

Sell a fleet of those Jody!

01-12-2011, 12:46 PM
Running nobbies too!! Daymn

01-12-2011, 02:16 PM
Thanks Guys.

Ya, knobbies work just fine in the dunes and let you do more sideways action and turn tighter.

Paddles are better for lifting the front end and getting there a little quicker.

RPM gearbox,,,,no problems,,,they have been working great.

Chain,,,,,no failures, but they do stretch quicker, and run hotter than our live axle set up.
I am running 530 drag bike chain

Last summer I would adjust the chain twice during a day at the dunes because of stretching.

a fleet :eek:

wait,,,,,how many is a fleet?,,,6? :)

They do typically stop stretching after they go a few days yes??

01-13-2011, 06:26 AM
Yes, they seem to stretch less after awhile.

Chain lube is a huge factor in heat & stretch,,,so keep your chains well lubed,,,,,often.

01-28-2011, 07:10 PM
I recieved some pics today from the International Motor Show in Doha Qatar.
I was going to fly out there for this,,,but other production work (non-buggy) got in the way :(
Would have been nice,,,cause it's cold here in Michigan





01-28-2011, 07:20 PM
Very nice! Wish you could have been there. Is the phone ringing with orders?

01-28-2011, 08:56 PM
Hey were all planning to run the MAORA series are you guys going to run?

01-29-2011, 07:47 AM
the phone is not off the hook yet:) we will see...

Nut, I would love to make those races,,,,,,,but we will have to see what winding road life brings us down this summer and if I can.

01-29-2011, 08:39 AM
Those are the shows to be at. My dealer spent like 200k on his booth for the Abu Dhabi show a few years ago, that's like a snickers bar for them though, lol.

I'm sure you'll make some sales from it............

01-29-2011, 09:00 AM
toot toot.

01-29-2011, 09:19 AM
I remember that, very cool display.

My dealer did not spend $200K on the booth though [smilie=alright.gif] :)

Yoshi, have you shipped quite a few over there now?

01-29-2011, 09:27 AM
I remember that, very cool display.

Yoshi, have you shipped quite a few over there now?

That was the big international show and the cost was both the booth and the attendance fee. Most of the shows aren't like that and there is no reason to spend that kind of money on majority of the other shows.

I haven't shipped a lot over there, I have 3 on the way there though. My rails are more expensive, you have a more affordable product and the smaller vehicles are blowing up right now (which is why my dealer is ordering SXS's from me now) so I would expect your sales to be better than for me. I wish you luck, there is definitely the market to make good money. Is that your first rail over there making a debut, or have they been there for a little bit?

01-29-2011, 09:43 AM
Sorry if mentioning what he spent came across as bragging. I meant it to show the kind of money they spend in that region as something to look forward to, not comparing my dealers booth to the size of yours.

They are 2 completly different shows and require different booths. I'm sure your guy could just as easily do something similar if he were showing at a bigger event....

01-29-2011, 10:31 AM
The booth is just to draw you there, it is the quality, craftsmanship, attention to detail that go into the buggys that will sell them. Well, the price too, but like you said, it is a drop in the barrell (pun intended) to them. Great job!!


01-29-2011, 10:31 AM
Nope ,,,,did not sound like bragging to me,but how crazy the difference in $$ is over there compared to the states.

I have 2 over there now,,,a single seater & 2 seater.
Both 1000cc with RPM gear boxes.

One was there last June,,,,,,in time for the intense heat testing,,,which it passed.
2nd got over there in December.

Thanks for the good wishes

02-01-2011, 11:42 AM
Hey ProtoDie, congrats on the oversea display!

02-01-2011, 01:01 PM
ProtoDie (http://www.minibuggy.net/forum/members/protodie.html) - Question?

I was looking at your website, and I wasn't finding pricing on your buggys. Am I not finding the right page? Or is it quoted per customer?

I'm currious because I've been wanting to build a 2 seat buggy for a while. But my current living situation doesn't give me a garage that I can build and weld a whole frame. I'd like to do the majority of the work myself, but starting with a frame and a few other parts that have already had the engineering done would send me a long way into the project.

02-01-2011, 02:08 PM
Here is a link to rolling chassis's

Rolling Chassis Kits (http://ptlracing.com/index.php?option=com_content&view=article&id=8&Itemid=16)

Here is a link to complete buggies
Protolite Buggies (http://ptlracing.com/index.php?option=com_content&view=article&id=7&Itemid=15)

Prices vary from level of completion and options, motor sizes, reverse or live axle.

Complete single seater ranges from $22,000 to 28,000

Complete 2 seater ranges from $24,000 to $30,000

The #17 SS1000 is an example of 1000 cc with reverse and would be $28,300.

02-02-2011, 08:39 AM
Congrats man thats awesome to have interest from Qatar I hope it does extremely well for you, you build a sick machine. Yoshi is right the smaller buggies are getting very popular

02-02-2011, 10:58 AM
Thanks DR,
I could use some warmth and sand right now.
Been out plowing the shop & drive ways all morning with the John Deere.
2ft of snow and 3-4 ft drifts :confused:

We are snowed in from the road and I snapped a hydraulic line on the tractor clearing it..................but it is not cleared out yet........so I can not go get a replacement line[smilie=alright.gif]

Oh well , back to work

02-02-2011, 11:06 AM
Wow just dont eat the brown snow cones...lol 15w40 doesnt taste to good..lol I've got the same thing here in T.O but we use a Cat 950e to clean, less passes lol

02-02-2011, 06:39 PM
Got it fixed & finished,,,,and yes hydraulic snowcones,,,,,no good

02-03-2011, 09:24 AM
Oh no.. sucks about the tractor.. man I better not say how I spent my weekend at Glamis in the 78 degree temps and loving it.. Oh I mean.. ooops... :p;)

Very cool about your buggies making it into the show and they looked great to me.. wow that back photo board is awesome and the buggies look great.. I think that's so cool and I also wish you the best and hope you make some good sells from it.
Congrats and good luck!

Yoshi, thats just crazy about the show and money your cars were in.. it looked awesome though.. wow actually very impressive. I wish you the best also.

04-03-2018, 03:01 PM
Ok, so we all lost build thread pics

I'm going to add a bunch of lost SS 1000 assembly pics to this thread

[smilie=drool.gif][smilie=ecstatic.gi:A true work of art in it's own right!

Almost to good to get dirty. Almost. [smilie=wink.gif]

Thankyou for the epic eye candy. Makes my build look rather crappy. LOL

04-04-2018, 02:36 PM
Thanks guys, hard to believe this build was 7 years ago
