Team NAXJA/Petty Cash Racing stock class KOH XJ build

The nose tires on a V-22 are 250 psi. I'm not talking about 235/75/15's. The portable nitrogen cylinder we use has 3000 psi in it.

Do you think I would make that suggestion without knowing what I was talking about?

Many people do just that these days Josh, and he doesn't know who you are. Don't let it get under your skin.
 
LOL, we are on a 4x4 site and you mentioned tires. Reasonable people who don't know you tend to assume vehicle tires, which is why I said "Not sure what all is in your tire servicing kits"

I see so many people saying such unbelievably retarded things in tech discussions these days that it's painful, which is why I wanted to make sure everyone knew the kinda pressure we're talking about. If you'd seen some of the discussions I've been involved in lately you'd understand completely I'm sure. pEple R duM. I'm glad you're not.
 
Back on 4643.


Did SFR motor mounts, block mounts, and trans mount.

Motor mounts went right in, easy fit. Not much to report there. Dallas did the install himself, since we're race prepping at his shop, and I think he enjoyed the fact everything fit like it was supposed to - even on this piece of crap car.

It's sad to note that I've had them sitting here long enough that he's gone through several batches of the new plated design, while mine are still painted.

The trans mount was going to be quite a bit trickier, as the Atlas t-case is taller than the 231/242 and hit the floor before it would bolt up. Alas, Dallas had accounted for this and built a plate to drop the mount in the crossmember.

A couple of cuts, and this dropped right in place.

For some time, we have been over articulating the rod end on the draglink. Looking at specs on misalignment spacers, I noticed all 7/8 rod end setups seem to be around 32*-34*.

However, when you step up to 1" rod ends, the numbers are closer to 64*. That works for us..

This is much better.

At full droop, a lot of room left to work with.

The Mark III 4643 Pottenger Power Plant (tm) has been awesome, but also somewhat of a problem - as we went a little .. ahem, overboard, in building the motor. It comes on hard around 4000 RPM and pulls until you're afraid to break the tachometer and back off. A lot of fun, and really even pretty practical for KOH, but on the short course it can be hard to keep the rev's up in the tight twisty's.

After talking with Russ for a while, we decided to advance the cam and bring the curve down a ways.

Its tight, but you can just do it without having to break the cooling system open at all.

Russ has gotten this 4.0 thing down pretty tight. Our old timing set was adjustable, but this new one has 9 positions and lets you get extreme - also, its stronger, and weighs less at the same time.

Didn't feel like we needed many pictures of this process, but swapped in some fresh springs. We run a custom variation of Deavers G80 Bronco leaf. Massive travel without ever inverting the spring.

What mods were required to run these? Off the shelf leafs or custom?

Using stock front mount. Axle moves back 2" or so. Build new rear shackle mount into rear bumper.

Could probably build new front mount, keep the factory rear with a custom shackle and keep stock axle location.

every time I drag my shackles down a rock, or back into them I with more and more I had done mine like this instead of just hanging them off the bottom. maybe someday I'll re-do what I did.
