View Full Version : Havasu Rorty R16 Shotgun

06-26-2008, 10:11 PM
Hi everyone! I have been working on my buggy for a few months and am finally geting around to posting it so you all can see.

I am going with the ecotec/CVT combo and power steering.
This is my first build, and am glad I found Rorty's plans they are great!

Here's a few pics of my build table and progress. Enjoy!

Nice work furtelli!

Keep up the pace and get it on the sand this year. Great choice on plans and power. Keep posting!

06-27-2008, 09:00 AM
Lookin' good! Keep it up. I am looking forward to watching your build, so keep us posted.

06-27-2008, 12:29 PM
Great start!!

Nice garage!

The best part of Havasu, besides the ďsand barĒ (For those that donít know it is like daily Mardi Gras on a lake / river) is that most of the homes have honking huge garages. Not uncommon to see a 2500 sf home with an attached 1500 sf garage. It is a RVírs toy junkies nirvana when it comes to housing options with garages / storage, etc.

Looking forward to watching the progress.

Thanks Yummi. We finished the inside a couple of years ago to start our business in it. It is a nice work area, but the floor is taking some abuse with this project.

Yes the garages here are awesome. I have a friend that has around 2500 sq ft of finished, air conditioned garage full of tools and muscle cars. It's increadible.

I got a some work done last weekend. It's looking like a car now instead of a boat.

I made the roof a little lower than the plans. I think it will look better and the smaller window opening should be safer.

06-30-2008, 08:05 AM
Looking good! Nice progress.

06-30-2008, 09:01 AM
How much shorter did you make the roof? I was thinking about that after seeing the other builds.

06-30-2008, 07:57 PM
I lowered it about 5.5 inches. I mounted my seats first to make sure I still have enough headroom.

06-30-2008, 08:08 PM
I'd like to see that profile. How much headroom remains?

06-30-2008, 08:33 PM

06-30-2008, 08:33 PM
Unless your name is Lurch![smilie=lmao.gif]

07-01-2008, 07:36 AM
After I mounted the seats I had a friend that is 6'1" come over and sit in the seat. I placed the roof 6" over his head. It wound up being about 5.5" lower.

I'll try to get some profile pics for you.

07-01-2008, 11:35 AM
Furtelli's right on with the revised roof hieght.. I'm 6'2," and if you build to the plans there's a full 12" over your helmet..

Furtelli (and all shotgun builders), Another mod to consider is to put a piece of straight tubing between the shock mount hoops across the back of the car.. it will run way above the engine and look like it belongs, and will help to keep the rear upper cage from bowing in in the event that you bottom hard on the rear suspension... my cage is bent up there and needs the mod.. maybe best to do it before it's a problem...

07-01-2008, 11:41 AM
I stretched the wheelbase to 111" and lowered the cage.Much nicer look.Rorty does a nice job but apparently likes the boxier look.

07-01-2008, 08:01 PM
Thanks for the tip Radio. I have been looking into different ways to make the rear stronger. I want it strong so I don't have belt alignment issues after I slap the tail in the dirt.

Are you the one that bought Standfast's car?

07-02-2008, 11:35 AM
Yes.. I bought Standfasts car.. you're absolutely going to love it, and your choice in drivetrain.... I've got to take the time to update Stand's build log.. over my head in work right now... haven't even had time for the car, but that should change soon... nice start on yours btw..

07-07-2008, 12:46 AM
My brother came over last weekend and helped me out with the top layer. Here are some more pics.

07-07-2008, 07:48 PM
Looking good.:cool:

If you wouldn't mind and when you get to that point of your build, would you attach a side profile pic with someone in the cockpit? I would really like to see the lower profile roll cage.

09-26-2008, 08:58 PM
I've been working on other projects lately, but now I'm back on the buggy and have an update.

The front uprights are welded.
The pass side trailing arm and jig are done.
The drive side jig is ready to weld.

I straying from the plans a little because I want the track narrower.

I repositioned the hub plate on the jig 3 inches closer to the center, but left the rest of the dimensions the same.

The trailing arm took more time than I expected, but I am happy with it.

I plan to shorten the a arms 3 inches also.

09-26-2008, 10:47 PM
Looks good.
Not sure how or if bringing the arms in 3 inches will affect the rest of the plans but
it might. Shock mounts etc. Wheel travel what not.
Anyways keep that stuff in mind as it looks like you already have a handle on all that.
Looks good hopefully you can post a little more often on your build.
Good luck with it and keep us posted.


09-27-2008, 12:25 PM
Thanks. It shouldn't change much in the rear except the axels will be shorter and that will mean less travel, but I don't think it will be a big deal.

Up front I expect to change the location of the shock mounts but still use the same basic design. Rorty has another car that is 3 inches narrower that uses the same front suspension componets and pick up points, so I think I will be OK. We'll see.:D

09-27-2008, 09:42 PM
Sweet, a buddy and I are going to start an R16 project soon with a turbo R1 powerplant. Funny I just moved from LHC. Awesome work.


11-19-2008, 07:57 PM
I have an update on my build.
The control arms are done and all of the goemetry seems to be correct.
I have the upper shock mounts figured out, I tweaked the design slightly for a sleeker look.
I found a low milage '04 ecotech complete with a MEFI ECU and harness.
The RPM box is on its way, and Neal at ATV racing is working on the clutch parts and jig to mount the motor.

11-20-2008, 07:22 AM
Nice work. I like what you did to the profile of the front end. How did it affect the placement of the upper shock mounts?

I am looking forward to seeing this thing rippin', so keep it up!

11-20-2008, 08:45 AM
Thanks, N8. I knew i was going to change the shock mounts because I moved the front bumper back and shortened the control arms. I figured out the upper mount placement by putting the arms in full bump position. Then I made a jig that is the same length as the colapsed length of the shock that I am going to use. This jig bolts into the lower shock mount at a 90 degree angle to the mounting points and puts the upper end where the shock mount should be. Then I bent the tube that runs frome the bottom of the windshield to the bumper so it intersects the point where the shock mounts.

I can't wait to get it in the dirt it's going to be a blast!:D

11-20-2008, 10:24 PM
Is the shock mont inside or outside? Bracing plan?

11-20-2008, 11:18 PM
The shock mount is outside, and I will follow the plans for the bracing.

12-14-2008, 12:04 AM
wish i found this thread sooner. ive been looking at that plan also.. probly be buying it pretty soon here. ciould have cut and bent two of everything as i am in havasu also :). looking good so far

12-15-2008, 01:40 PM
Thanks. I have been happy with the plans, they are very complete.
Order them and get going.:)

06-21-2009, 10:03 AM
Have been making progress on the buggy. The frame is completly welded, the RPM box is mounted and I am working on getting the motor aligned and tacked into place. Thanks to Moto1 and K-fab I used their ideas for an adjustable motor mount and a way to temporarily suspend the engine in the correct position.

06-21-2009, 10:31 AM
Nice work. The engine - RPM alignment idea looks solid. The garage must have AC . . .

06-21-2009, 10:49 PM
Wow, just found your build, that is killer! great work, your moving right along, I really like the lowered cage, do you know your over all wheel spacing, you did narrow the rear, but not the front? nice work on the motor mounting and RPM mounts, that is really time sucking.. we are plaining a lake trip to havasu, in the picking the date stage, any suggestions on when not to come?
keep us up to date on your build & great photos also..

06-22-2009, 07:03 AM
Man, Furtelli, you're you're making me look bad - that engine suspension cradle's very nice compared to the cobbled up thing I did.

The work looks really good!

Is that an ATV Racing alignment jig? I've seen a couple floating around ATV that look very similar.

06-22-2009, 07:42 AM
Thanks guys. I narrowed the front too, but not as much. Overall width will be about 84 inches.

I got the jig from Neil at ATV racing. I put the belt on without the springs in the clutches and it seems too loose - like I need to increase the spacing. Even with the driven all the way closed there is a lot of play. Neil knows what he is doing and maybe the belt will be tighter with the springs in.

K-fab how did you attach the straight edge to the motor? I am just sandwiching it in the drive clutch. I am having trouble with the motor moving a little when I tack it. Neil said alignment should be within .005 in. I still have to grind the tack welds off and reposisition again because it is not quite right.

Best time to come to Havasu is earlier in the summer before the monsoons.:)

07-25-2009, 12:14 PM
I got the exhaust figured out. I am not sure if it needs a hanger on the muffler. What does everybody think?

07-25-2009, 12:35 PM
Maybe if you hang a muffler. That looks like it will be loud.

07-25-2009, 07:40 PM
OMG! :eek:
That thing's going to be obnoxiously LOUD!

Short pipes - no low end either...
I'd be adding more tubing and a muffler.

07-25-2009, 09:58 PM
There is a muffler there. It is a 10 inch supertrap, I don't have the discs in yet. I was hoping I could adjust the back pressure and make it quieter with the discs. If it is too loud, i will have to redo it.

07-26-2009, 09:50 AM
That setup will be very loud. Hate to be the bearer of bad news...

I run a Super-Trap spark arrestor with about a dozen discs on it after the Magna Flow mooffalata and it's still louder than I'd like it to be.

07-26-2009, 10:34 AM
Same with me. Twelve discs and hearing protection needed.

Your pipe looks good though!

07-26-2009, 12:25 PM
There is packing that goes in the supertrapp as well as the discs. If I cut it down to 6 discs will it make much difference?

I can try to reroute the exhaust and squeeze in a muffler and then out the supertrapp.

I don't want it too loud. What style or size muffler is most effective at cutting noise?

07-26-2009, 03:10 PM
Mine has packing too and the Supertrapp just isn't effective at managing noise.

Borla for a Corvette would look good and recuce noise. Shame to lose that purdy trap though.

08-12-2011, 08:20 PM
YO Furtelli?

08-12-2011, 10:04 PM
Hey Bull. I'm still here. Been slowly chipping away on the buggy. Starting to see the light at the end of the tunnel:) I'll have to get some pics up for ya.

08-12-2011, 11:22 PM
See Bull.... This is the Where are they now type of thing I was talking about.

08-13-2011, 02:48 AM
Ya you better post some updated pics soon or Im going to drive out there and find you the next time I visit my sister in law in Havasu and look at it in person..

08-13-2011, 05:03 AM
Yeah, for sure. You have to be getting close.

I'm thinking Havasu would be a possible vacation home spot for my waning years. That or somewhere else in the vicinity. Not Cali though. Nevada or Arizona and Nevada preferred because of taxes.

08-13-2011, 02:35 PM
I lived In Lake Havasu for a few years.... Lots of fun and from all over town... the water is 20 minutes away MAX... Great restaurants. Must have a boat<<< (sucks with out one)
We used to work early mornings... and fish the rest of the day... Awesome place and well during the spring time and fall.
Too bad it only has 2 seasons..... Warm and Gosh Damm HOTT!

08-13-2011, 04:56 PM
Project is looking good! More pics please![smilie=jumping.gif]

08-15-2011, 01:07 AM
here are a few pics.

08-15-2011, 03:49 PM
The car is looking great. The Eco and CVT should be lots and lots of fun. Builds like this are quite inspiring.

08-16-2011, 09:37 AM
Thanks Gene. If any of you guys are come to Havasu give me a shout, It would be cool to meet up.

08-16-2011, 11:56 AM
Thanks Gene. If any of you guys are come to Havasu give me a shout, It would be cool to meet up.

I will take you up on that when I do make it up there....

08-07-2013, 05:42 AM
What ever happened to this build? Did the builder complete the buggy?

08-07-2013, 06:49 AM
What ever happened to this build? Did the builder complete the buggy?

I am still wonderin where Gene got lost[smilie=dunno.gif] I hope the natives didnt get him [smilie=whistle.gif]

08-07-2013, 03:43 PM
It's alive!

I'm working on getting some pics up but am having trouble resizing them.

No more time now. I'll try again later.

08-07-2013, 03:53 PM
Nice! Look forward to some Pics!

08-07-2013, 03:56 PM
Furtelli,great to see you still at it.

Is that VCT on the floor?

I'm going to do that in my new shop.

08-07-2013, 10:46 PM

08-07-2013, 10:54 PM

08-07-2013, 11:07 PM
I really like the side profile of this buggy. Did you do an overall weight when completed? Did you do any engine mods or running stock engine and stock ECU?

08-07-2013, 11:14 PM
Finished weight is around 1800 lbs. The engine is stock except for the header.

08-08-2013, 01:10 AM
Nice! Now when do we get to see the video?

08-08-2013, 06:33 AM
Your buggy looks great .. Like others have said that side shot is a mean one :cool:

08-09-2013, 07:32 AM
ABSOLUTLEY AWESOME!!!!!![smilie=rockout3.gi:

08-09-2013, 11:59 PM

08-10-2013, 10:01 AM
Great work man, probably my favorite buggy EVAH!!!

08-10-2013, 10:32 AM
So how do you like it?
Handle good?
Jump good?
Any issues future builders could look for?(Other than Rorty selling his company)

08-11-2013, 08:51 PM
I like it a lot. It handles good. I am inpressed with how smooth it rides.

I didn't have any issues during building, but I did make changes on the front bumper and the tubes that connect the bumper to the dash area. I also lowered the roof and redesigned the rear shock mounts so I could run the bypass shocks.

10-13-2014, 09:57 PM
could you elaborate on the changes you made? i am looking into building this exact buggy and would like to know what kind of things to look out for and how to plan for it?
