Powersteering

I am finding it to be too sensitive for my driving style.

That seems to be a standard concern with his conversion.

That being the case, have you spoken with Steve about this? Perhaps he has designed a work-around change?

I have not looked into it but there are internals to the power steering which can reduce the force tuning the feedback to what you like.

I am putting power steering on mine but the raq came from a smaller car. There is actually a lot to getting all the geometry correct. There is a lot more to it then simply swapping a raq. I should be painting the car in Fem or march so the final install won't be till this spring.

I actually think that you can install an adjustable pressure reduction valve in the pump out put line. That would reduce the sensitivity and enable you to set it to where you like it.

I don't think that you need anything fancy. An industrial valve should work. Maybe Ron here can help you pick one out?

I talked to Steve today and he sells a valve that goes in the hardlines up at the rack for $120ish. Then I will need to make new hardlines and some AN fittings but says this will solve my problems.

Correct about the valve. Since the rack and pump should be matched but few are on a conversion such as the Pantera, a flow reducer valve is needed. Speedway Motors sells one specifically designed for the unholy street-rod combination of a Ford Pinto rack (needs 3 gpm) and a GM pump (puts out 4 gpm). When Gary Hall began doing a few conversions like this in the '80s and was unsatisfied with the results, I mentioned using a needle valve to find the flow rate that gave some power assist without over- or under-boosting. Remember you're dealing with up to 1000 psi, so use premium fittings!

The setup on my car is from Steve. He says that it is twitchy on flat side cars and real good on wide cars. The valve is one he uses on the kit for my car but somehow it didnt make it on mine when he did it.

There were two kits. Wide body. Stock body. Stock body gets the valve. You have the wrong one OR you have the first one and the valve wasn't in the kit yet.

Either way, problem solved.

My guess, I think this valve is going to be like the Corvette/Shelby adjustable (competition) rear brake proportioning valve. That's a $120 valve and is a Borg Warner piece.

That one is adjustable with two wrenches on it.

There is another one from Tilton I think that has a knurled knob on it so that you can adjust it without the wrenches.
