Buggy build - project 'simplicity'.

Buggy build - project 'simplicity'.
I am starting a buggy build for the 2010 KOH race. A full buggy is, IMHO, all that can survive the punishment of that race.

My YJ is going to be used for the qualifier in Colorado this Fall, a hill-climb.

Team TNT has been sponsored by Clayton Offroad and by Pitbull Tires, and some local businesses as well.

We are currently building a new engine just for this project, a 4.7L inline six stroker.

Clayton needs specs before they can start building our arms.

Here are the excel files for our suspension, completed. Feel free to download and critique. It is based of off my SniYJ, which works well:

The biggest factor in this build is simplicity. Here is the chassis I am using for inspiration:

I like the 'inspiration' cage, good choice.

Simplicity eh? Whats simpler than the number 1? Have you considered 1 link suspension designs?
I have too many projects

Actually zero is simpler - one is unity and the building block of all the basic functions.

Simplicity:

- Hydraulic automatic transmission, no computer.
- Jeep 4.7L stroker running on Propane with an HEI distributor - one wire, no computer.
- Single ended hydro ram for steering, mounted behind diff with keyed Reid knuckles and arms.
- Dana 60/Dana 70 diffs. Minimal bling, maximum brute.
- FOA coil-overs and air bumps.
- Atlas 2 t-case, 32 spline outputs.
- Engine mounted at point where only one spare driveshaft is needed.
- Gauges = trans heat, engine heat, oil pressure, voltage. Thats all.

Re: Buggy build - project 'simplicity'.
A true master doesn't need to look at a tach, the beutiful sounds of the engine revs are music to the ears. :wink:

All I ever do with mine is look at it and say "wow that wasn't good"

This has the recipe for a really reliable race rig, and quick to troubleshoot/repair also!

I have my choice of all the Pitbull tire line-up.

I am leaning towards the 42" Rockers - but with tires this big I may need to turbo the engine.

Don't forget, you're gonna have a bit less weight with a tube chassis = better horsepower to weight ratio. :wink:

Re: Buggy build - project 'simplicity'.
Tonight I used my 1985 CJ-7 forklift to move the Dana 60 and 70 into their new spot:

[Image: buggy3.JPG]

I found out all the information on the differentials here, this link lists EVERY Dana differential ever made:

http://www2.dana.com/pdf/X510-9.PDF

The front 60 (ID# 610295) is from a 1988-91 Chevy V-30 SRW 1 ton truck.

The rear 70 (ID# 603695) is from a 1979 Dodge D-300/400 truck. It is the HD, or heavy duty version, and has 35 spline shafts.

The plans for the diffs are as follows:

Front: Detroit No-Spin, 1480 yoke, 5.38 gears, Yukon inner and 35 spline outer shafts with Superjoints, 3/4 ton brakes, Dedenbear outer knuckles, Parts Mike springless 5 bolt arms, PSC single ended ram for full-hydro, Poly drive flanges, GLO cover.

Rear: Yukon 35 spline shafts, steel spool, 5.38 gears, 3/4 ton brakes, GLO diff cover.

Are you going to weld it - I don't think anyone is making a D70 spool at this time. Just curious to see if my knowledge base is slipping. Mrgreen

If one is not available, I will run a Detroit - they are cheap - my year of 70 has a split carrier.

Will this thing ever see any pavement? Will it ever have any additional weight besides itself? I seriously doubt it.
