power steering setup

[JJK]

I aligned my car this weekend with some help from local builders (this community is great) and took it out for a drive yesterday. I have +7.5 caster, -0.5 camber, and 1/8" toe in. It runs straight but requires a bit of effort to engage a turn, almost like I am driving in grooves and have to get out of them. But once I begin a turn, the steering becomes rather loose and twitchy. I think I need to dial back the caster a little but am concerned my power steering components are not mated correctly. I ordered the complete kit from FFR with power steering rack and a BPE engine from Factoryfiveengines, so assumed the PS pump and rack would be mated up. When I called BPE, they said it is a GM style pump putting out 1200 psi at 2.5 gpm. FFR tells me their PS racks are for 87-93 mustangs, and he thinks the pressure should be 800psi. I could not find the actual pressure for an 87-93 mustang rack listed anywhere, so either he is correct and I may need a proportioning valve, or he was mistaken and things are matched correctly and I need to work on the alignment again.
Can anyone confirm the pressure for an 87-93 rack? or, any other tips?
Thanks

The Saginaw pump is too much pressure for the Ford (FFR) rack. Not really sure why BPE doesn't advise when they are aware that the customer is using the engine in an FFR???? Restrictors are available from CVF Racing.

Jeff,
Thank you for confirming. Yeah, BPE setup a website called factoryfiveengines, so they know exactly where the engine is going. Disappointed this was never mentioned or accounted for, but now I know.

Sorry for hijacking this thread, but Jeff, where is this restrictor located? Does it fit in-line with the port outlet and the high-pressure line, or is it buried inside the pump body somewhere?

Asking because I'd like to see if I have a restrictor already installed

Thanks !

It's installed inline with (just below) the AN port outlet. I have successfully used the CVF pressure reducing valve.

Another option might be a PS pump from a 99 Explorer. I used this

The pic shows one w/ a reservoir but this # is for one that uses a remote reservoir. It looks to me to be a GM style pump but the pressure must be right for an FFR because I used 2 of them over about 14 years.
