The truck is almost prepped but i dont think this truck will ever be loaded up on the trailer fully prepped. It will always be finished up on the trailer or in the des before the race haha. We are gonna try running a bmw fan with a bosch motor. A buddy is a bmw mechanic and the low speed module went out on on a fan so he gave it to us. He told us to just wire it direct for high speed and says itll last forever, so were gonna give it a shot.
Last race the truck was way smoother on valving but there was a little more that could be done. We were surprised though that even when we would run the truck for hours and then through some rough terrain at race speed (on sunday) and then instantly check the top cap temp with a laser gun, all the shocks were around the same temp. Rear bypass and coilover were between 180-195 and the front co was 200 and bypass was 150. Ive gone through and revalved all the shocks, limited the rear bumps to 2.5" travel, and dropped the bump psi from 200 to 80 (dont know why i didnt drop pressure sooner). I think this will keep our rear down more and be less likely to stuff the frontend. Ive also put more valving in the front bypass and takin some out of the coilover to avg there temps a little closer. I think the front byp runs so cold though because it has all the direct airlfow.
We finally went back to a rubber carrier bearing before the last race and ALL of our vibs went away. It drives like a regular car on the street now. Im still worried about the rear slip not slipping fast enough and pulling and pushing the trans slip in and out though.
Before last race we finally got a trans temp sensor on and found out the lines to the cooler were backwards (OOOOPPPPSSSS). Truck always drove so we never thought there was an issue, but the temp got up to 230 when we test drove out at the race. We swapped the lines and without the fan off it would stay under 180 all the time and with fan on itd never go above 150 during the race. After the line swap i had to adjust the fluid level and i looked at the fluid and it was all still bright red so i dont think it got burnt too much. Also with our old 4.30 gears, our 3rd gear would top out at 75-80mph. We have cut the wire to the trans lockup since then and put in 5.29 gears . . . . now it seems like 4th gear tops out at 82mph and it wont go into 5th WTF?!!! So we are taking others advice and putting the lockup wire on a switch and well see if the next race we can push to mid 90s or even into the 100s. I know the last 4 miles of this marked course we could hit mid 90s with the 3.4 and supercharger, so i dont doubt we can hit that again or higher if the track is close to the same (maybe it wont be).
Went through and also replaced all the heims and unis that were just flopping around without liners (like ALL the steering heims haha) and I will be cleaning up stuff here and there that was tossed together in the des.
I ended up making it a steel bash plate like i made in front of the steering box. Ive replaced the lower tube since it was destroyed at the last race (it was a 3/8 thick tube) so the new one is solid in the middle. I used the steel bash plate to tie the lower bumper into the front crossmember so nothing should move now. I only welded sections of the bash plates so they can be cut out later somewhat easily and replaced. The lower plate has vertical ribs on the topside to keep it from bending. Still gonna leave the side open for the steering and well see how it goes. I dont want a plate to cover the steering, get bent, and lock everything up.
Also made an aluminum visor
Were gonna try out some booties on our high wear heims and see if they last longer or if the booties just hold in dirt or get chewed up
And heres our overflow now. Got rid of the monster can cause rocks from other vehicles kept putting holes in it. Id like to make this much larger though and hold about 1 gallon.
