All in all, I think Ron should be pretty proud. Other than the steering issue, there weren't any other mechanical issues. It wasn't fun or easy to drive. It had understeer on corner entry, mid corner, on exit and in a straight line :lol: seriously, if you weren't conscious of unwinding the wheel, the car would plow through the straights with the wheel turned until a dab of brakes or a little too much throttle made it snap. Ron worked on driving around the cars weaknesses and did really well out there, especially for his first autocross!

Generally just raising the front off the ground - open the cap on the reservoir - and running the rack lock to lock a few times is adequate bleeding... but with extra lines -- and coolers... you'd have to look for a "high" loop where maybe the air is trapped IDK.

Sounds like Ron built the perfect pro touring car based on proven recipes. :lmao:

Yep 335/285 stagger hard at work. Form over function.



Sounds like Ron did just fine.:trophy-1302:

Fix the steering issue and get some seat time in the thing. Then new rear inner hoops and a 315 tire will fix you right up.:mock:

I have power steering on the Muttstang -- and Charley doesn't on his... he's always worn out at the end of the day and mentions "me" having PS and him not. I think there's larger issues at work but WTF we're friends and I just accept his whining for what it is. HAHAHAHAHAHAHAHAHAHA

How long is the pressure hose from the pump to the rack? Make it as long as you can. What happens is that it's a rotary pump which is not constant displacement so the longer hose helps the small pressure surges that the pump creates to be come smoothed out in that longer hose. COMPRENDE?????

I was blown away at what that did to our power steering system just by making the pressure hose like 30" long if memory serves me correct.

Very cool Ron. Looks like you have graduated from the jack stand army. Welcome aboard. :thumbsup:

Now get ready for the sleepless nights trying to figure out how to improve car and driver :headspin:

Great to see you’re out there enjoying the car! The autocross video was good, but I’m looking forward to some high speed stuff to hear the 427 wound up :yes:

The car looks awesome.

Hey Ron it was nice to meet you and figure out where I had seen your car before. lol.
Congrats on the cars maiden voyage at the track and your first time auto crossing. Once you get the car all dialed in, you will really enjoy auto crossing in it. Your car turned out great.
