I put the Lee Saginaw-in-Ford-dress in the Heap, upon Josh's recommendation.  Works way  better than the 5.0 pump I had been running.  I too have a Borgeson box.  No noise, returns to center much better, slightly more effort. 

Just a note … I have a Saginaw style Borgeson pump on my R&P steering.  Borgeson sells a pressure kit #899001, so that one can match the proper pump pressure needed for their particular system.  I found that I was running too high of a pressure and needed to reduce it on my system as the steering was ‘touchy’ when slightly turning the wheels especially at highway speeds.

Good info.  I haave done that once on my KRC pump.  And, you can get a kit of different sizes from TCP.  At least I did.

On my KRC pump with TCP rack, I bought the most restrictive orifice they make.  Steering feel improved drastically.  I wish they made a more restrictive one, but I guess that would be called MANUAL STEERING.
 

I went with the saginaw style Borgeson conversion on my 65 MS about 8 years ago. Works well, had to replace the pump after last trip to Montana due to excessive heat caused from a leak driving home. I "boiled" the PS fluid yes boiled the fluid coming home near the end of the trip. I was toping off the pump after my last fill up and could hear it bubbling inside as I filled it. When I replaced the pump I found the pressure hose was so hard from the heat it was cracking apart. The new lines they sent me were longer and I was able to route them up and away from the exhaust better, first kits had them just to close to the front exhaust. I also have headers now and I  installed the Hi heat plug boots on the line just for added safety. I do find it to be a very tight driving feel. 

Raymond B, it's a lot easier to change the shims on the pump

Dumb question, but could a larger pulley help with the "over boosted" setups?

 
Trucks already have a larger pulley compared to Foxbody.

I’m no engineer, the larger pulley would only decrease the pump’s rpm’s.

The relief/bypass design pressure would still be the same.




The “piston “ with the nut and washers is from a remanufactured pump and the other one is a factory.

There appeared to be a spring/check ball inside (couldn’t disassemble either without damaging).
I believe the washers on remanufactured pump piston sets the system pressure.

Yeah I get that it's easier to shim or use restrictors, but one comment said they had used the smallest restrictor and it still felt over boosted, hence my comment. So lower RPM would not = lower pressure? Seems like it does with an oil pump...

I am running a KRC pump on My race car. KRC has a wonderful selection of pulleys and brackets and valves/orifices to get you dialed in just right. The 5.0 pump said uncle when I built the new motor with the Motorsports block and started seeing over 8000 RPM. KRC set me up with all the right pulleys brackets and spacers to succeed.

Some may not be aware.  KRC pumps also are offered in other less expensive variants than the aluminum one offered through TCP.  And, if you go to SPEEDWAY, they offer many different types of circle track pumps that are similar, and most are not expensive at all. Like $100.  And they have brackets and pulleys for Fords. I think I paid $45 for my brackets, but that was over ten tears ago.

For those not familiar with SPEEDWAY, they also offer lots of fabrication stuff like frame brackets, swedged, threaded tubes and many other specialty items.

The 9” differential in my 69 even came from them with their name cast into the housing. It cost half what I had paid for one from Strange but it is silent, unlike the Strange.  I guess that noise costs extra.
