Go-Fast Trail Rig

Picked up a 95 Orvis a few weeks ago.

Already had a RE long arm kit, ACOS Bumps, Bilstein 5125's, roof mounted rack with lights and an e-fan conversion.

Will be building it as an adventure rig, with a focus on go-fast and dirt roads.

Started like this the first day i brought it home.

First thing i did was remove the roof rack. Too much wind noise, and it just made the Jep look too tall.

Apparently i bent the rear D35 beating on it out in Johnson's Valley for the MORE Night race...

Now it'll be getting an 8.8 from an Exploder with disks.

Jeep is currently at Creative Fabworks getting a light bar/nerf bar built for the front, and mounting a pair of 2.5x10" SAW's. Searching for a matching set for the rear.

Nice. Are you concerned about the extra lights up front blocking the radiator?

I would. Two 8" Hella's mounted on my front bumper raised the temp 10 degrees.

Looks nice.

Are you planning on trussing both front and rear axles? If you plan on doing go-fast stuff, I would seriously consider trussing the axles. Also remember to weld the tubes on the F8.8 to the pumpkin, that is a weak spot on them.

Does it do that on all temps/ speeds, or just during hot summer days when wheeling/ slow traffic?

I have my winch tucked almost into the radiator, blocking airflow quite a lot, and I've never had the temp creep above 220* even when wheeling hard (WOT in deep snow or mud for extended time); 99% of the time it stays constant at just about any outside temps and driving speeds @ 212*F (just like it did as stock).


I'm just wondering, since I've seen this subject pop up fairly often. Is the niner e-fan system more effective at low speeds and low engine RPMs compared to viscous fan @ low RPMs? I do know viscous fan has better CFM rating at certain RPM levels compared to e-fan at high speed, but I've never seen any comparison between the system at lower RPMs under low speed..

Yep, tubes will be welded to the pumpkin, and I'm going to be using the artec kit for the truss and bracketry. For the price, you really can't beat it. When I get around to finding one, I'll have an HP30 trussed up for the front. The jeep is not a DD by any means, so I'll probably wait to install the 8.8 until I have the hp30 ready, and just reggae then. It has 32's now, and when I step up to 33's I'll put in 4.56's

In regards to cooling, I'll be putting in an aluminum radiator soon, as the jeep has 221k on the clock, and the stock radiator is likely a ticking time bomb. It has a pretty aggressive efan, so I'm honestly not worried about low speed airflow. I'll keep an eye on temps and see how it does. I was also considering taking a hole saw to the bumper to let air in there.

Timo, glad to read your comments on temp and airflow, it's nice to get some real world feedback on that vs web-wheeling opinion.

You might even want to consider 4.88s, depending on what you're looking for power- wise. Especially if this is not a DD, go with 4.88s and 33s. I have 32s on my niner with 4.56 gears, and I love it. I'm doing 80/20 street/ wheeling, and I can't complain with too high RPMs on the highway.

I have 12 pieces of additional 2" diameter holes on my bumper lower plate to help with cooling, so that probably is helping quite a bit at low speeds. Do as much as you can to improve airflow, it never hurts

One reason for my operating temps staying good and steady is most likely due to local ambient temps. Even in the summer we very seldom exceed 80-85*F and usually hover at around 65-70*F; on the other hand even during winter @ teen temps or lower, wheeling in deep snow doing 1-5mph @ WOT for a few minutes straight will strain just about any cooling system. Airflow @ higher speeds in high ambient temps help a lot, even at highway- speed races on the desert.

That being said, I would make sure your cooling system is up to the job with the temps in SoCal. Good all- aluminum radiator and properly set-up e-fan system should do the job.

Did some small things today. Worked on a bracket for the rear dust/camp light, and we cycled the suspension to get bump placement and limit straps.

The shock will need a 90* fitting in order to tuck up where the factory shock was, so the hose guy is going to stop by the shop and see what he can do there. Hoping they'll be mounted by the end of the week.



33's tuck in nice

Here you are; just put in the notes when you order that you're 96+ and he'll correct the number of grille slots.
