Predict Vacuum for Brakes
Hello all,
Is it possible to determine if a power assist device such as an electric pump or hydroboost like device will be required to support a power brake system? I've installed wilwood discs on all 4 corners. I had initially considered going with a manual set up but I've had a change of heart. I would like to get away with a small power booster if possible. Cam is a Comp Cams 248/254 @ .050, 618/638 lift 112+4 LSA . Displacement 522 and 340 heads. When the motor was run in, it really had a pussy cat idle compared to what I had previously. Very smooth sounding but this is an area where I have no fundamental experience. Thank you.
