With Bob Stone's hydroboost kit using a 40mm master cylinder we were able to get 1,400 psi brake pressure. The limiting factor seemed to be available
pressure from the steering pump. PSC sells a new Saginaw style pump made by Delphi that is supposed to output 1,650 psi. The PSC pump I installed did
not quite do that until the relief part of the flow valve got tweaked. After that we were able to get 1,600 psi brake pressure with Sue on the pedal.
We have Manny's reaction arms on the rear and were not able to drag any tire on concrete at 1,400 psi so more pressure should be more brake. Calipers
are 80mm front and mid with 66mm Kelsey Hayes park brake on the rear.
