WOW Those adjust on the fly swaybars are slick. Some of the rock racers in ultra 4 racing use a lever actuated swaybar. it allows the driver to disengage the swaybar on their machines when they leave the highspeed desert race section of the course and enter the slower technical rock sections...

solid ball joints/suspension joints are going to make a little more noise. clicking and such is normal. dont spend too much time fighting it. make sure nothing is loose and that the joints are healthy and call it a day.

louvers could look cool out back. get a lot of cool air on that 600hp beast...

In the world of rockcrawlers/rock racing (only world i know) overheating is a constant thorn. Ultra 4 race cars (rock racers) have powerful v8s (mine is underpowered by current standards at 500hp) that find themselves working really hard in a car that is often moving really slow. Motors and...

That reasoning makes sense and car builds like these are a kind of big kid science projects where Ideas are tested. …But this EWP idea smells potentially like over engineering. I would hope that the combo of a proper radiator and a proper pair of fans would keep these cars cool even on hot days...

Id test the car first before adding the pump. if I used an EWP id get rid of the mechanical pump

i had some doubts about these little lithium batteries until i started using them. When My Ultra 4 car was built I had the builder install a pair of odyssey metal cased Gell batteries. After a couple of years of bashing the race car in the desert and on the rocks the gell batteries had some...

I’m using the sump welded onto the side of the tank as designed by Earl. In this case the Hydromet fits exactly into the bottom of the sump. Instead of securing the edges with those glued on devices I secured the Hydromat a little differently. In this case there is an Aluminum line going from...

A little bit of a dilemma with this shifter cable arrangement. This car originally came with the OEM shifter assembly and the associated cables. Now that I have the upgraded shifter these cables don’t seem to work. I suspect they don’t have enough throw. I measure only about 1 1/2 inches of...

Yeah the handbrake was a bit of a challenge and I have doubts to its efficacy. I think if I had to do it over again I would’ve used one of those electric caliper kits now available from Wildwood I finished the bulk of the oiling job. I did go ahead and abandon the parallel oil coolers routing...

The way it’s set up now the seat is centered with the steering wheel

I think I figured out the E brake for now. Took a little more tweaking than I would’ve liked. The system seems to squeeze the calipers pretty well but I’ll have to test it on the street I really do like these tillet seats. But I’m only five 8 and 170 pounds. I bought a few sets of brackets...

Well that’s what I came up with for the fuel pump and filter assembly. Used those isolation bushings on the fuel pump so hopefully it will send less vibration into the cab. I will runner manual cable to the fuel filter/valve so that I can shut off the fuel from inside the cab I tried to put the...

Working on a mock up for the fuel system. Question for those gurus making these things-Is there any reason why I couldn’t place the fuel pressure regulator on the same plate or does the fuel pressure regulator need to be up higher? As in does the fuel pressure regulator need to be up above the...

The oil system is about all done I am mocking up the fuel system now. I’m trying to put everything on one aluminum plate that I can easily remove and take to the workbench for future maintenance When needed.

Slow and steady. Getting stuff done between job and family. Decided to go with one of these lithium ion batteries. This is a 720 amp battery and it’s the same one I use on my LS three rock racer. Made this little bracket with the band saw

i too appreciate the seat research. i baught some different brackets also (sparco, etc). But as experiment Im thinking custom is the way to go. Its a shame someone doesn't sell brackets like the ones you just made,,,

I guesstimated that i needed 2 coolers based on cooler recommendations from the Pegasus racing website. Although i dont plan to track the car hardcore, im trying to build a "race car" to a standard for which i have no experience. In my mind im commited to 2 coolers for the oil. i was getting...
