Dirt Missile rebuild begins

[Blake Foster]

A little update after the test day.

found the Dry sump pump and a slight weep between stage 3 and 4 so we sent it back to ARE to find out why. he has not seen that in the past so he wanted to see it.
talking to Greg's friend Bruce about the Vbox camera system and he suggested using the CANBUS info from the Holley Dominator to give much more info to the vbox display and use it for more tuning!! we also are adding brake pressure input to the Holley/ Vbox so that will display as well, this should be helpful in seeing what is happening on track and could help make for quicker lap times if that is the goal................
had time to remake the belly pan parts that were all tore up from Thunderhill.

Interesting tuning observation we had 1.5deg neg camber. in the car tire wear and temp 180 ish was close but we added 1/8 shim to give almost 2 deg. and the inside tire temp went WAY 220 if i recall up and the added wear showed as well. out came the shim may go 1/2 way and add 1/16 shim if we get any more test time on it. But that was very interesting to see a small change make a big difference.

Blake, I have run into this before with a lot of dynamic (full compression) caster. If the suspension is set up for a lot of caster gain with travel, then the camber can get way up there when the wheels are turned, adding to the static camber. Just a thought, fwiw.

Edit: When I maxed out the caster (mechanical limit) on my Viper, I had to back the static camber down to -1.8 degrees from -2.6 degrees to make the tire temps happy.

Cheers

Nice to see this work out so well!

.5 degree camber adjustment to me is alot when when you get over 1.0 negative camber. If its a couple tenths off from side to side I can feel the difference on the highway.

I have a “surgical procedure” tomorrow at The Mayo to clean my liver stents out — and HOPEFULLY that restores my energy level..... IF (big IF) that works — I’ll be headed to pick it up and try to run it mid May at Thunderhill....

We shall see. It’s anybody’s guess.

That’s why I’m so pissed at Sutton — #1 because he just flat out overstated his abilities.... and knowledge.... and that cost me TIME I don’t have. I felt good last year when it was “finished”.... Now the cancer has progressed a whole year....

Endeavor to persevere. 👍

Car talk is one thing Greg, but more importantly...I pray everything goes well with your medical procedure today. GOD shall cover you with his mercy and everything will be fine.
