Quick numbers question not covered in the chassis manual. I'm looking at installing either a 9" slimline booster/ master cylinder (900psi, 1200 psi max) ..or a 8" dual diaphragm booster/master cylinder (1000 psi/1400 psi max) (Both from Master Power Brakes) Both are good, but I'm wondering how these numbers compare to a properly operating 11" original-style booster. I like the idea of a smaller, more ergonomic unit, ommission of the hold-off valve as it is incorporated into the MP combo valve, and it's all great quality stuff......but I do not want to compromise too much in the way of braking... and I'm not sure what the pressure would be on the 11" unit for comparison purposes. Thanks..again!
