One of our well-informed members developed the following and sent it to Bob Stone who asked me to post it here for him. (Bob doesn't use a computer)
"Master cylinder booster combinations and theoretical pressure"
1. Force available from vacuum booster Dave Lenzi panic stop 1,473 lbs.
2. Force available from Hydroboost 1.56" piston diameter and 1,350 PSI steering pressure 2,579
Vacuum Bob Stone
Booster Hydroboost
1.25" master cylinder 1,198 PSI 2,098 PSI
34 mm master cylinder 1,048 PSI 1,835 PSI
37 mm master cylinder 852 PSI 1,549 PSI
40 mm master cylinder 761 PSI 1,332 PSI
The Hydroboost force does not include additional force that can be applied by the pedal.
