The power steering issue I'd be looking at -- belt slippage.... or air entrapment...

That sounds like a full day Ron.

Nice you have a job you can go back to and get some rest.

I'm wondering if there is some air that just doesn't want to get out. Or, its possible that the pump isn't properly matched to the rack. The DSE racks like to see 1400psi pressures at (I believe) around 3.2 gallons per minute. Having the flow rating, but not the pressure might be responsible for the irregularity.

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 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!

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

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

Sounds like Ron did just fine.

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.

Matt -- You may be on to something there with the flow and pressure. I've seen plenty of guys running GM pumps with Ford racks and then complain that they're steering is too light... well DOH! A simple orifice change and it's bada bing bada boom!


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.


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

Back on the grid!

Can always count on you two for a positive poke

I experienced a similar problem on the DSE rack on the Chevelle we just finished.

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.

I tried to look at your pictures to see how long the pressure hose might be but after going back 10 pages and not finding any actual pictures of the car or engine I gave up.
