Like the subject line ask I would like to know how the brake booster reacts to a super charger that is pumping in 6 to 12 pounds boost

Please go into detail as to what is required to keep the brakes working normal under high boost applications

Thank you
Brad

Google is your friend

Something about not trying to open the throttle while pushing on the brakes and a check valve serving the booster.

been there did that Bill before I posted.
The check valve protects from boost and allows for one application
but I was looking for technical information not what just gets you by in a pinch

Probably need to talk to your SC vendor, or maybe someone who's done it will chime in.

A RL search implied that you get several tries on loss of manifold vacuum, and you can test this.
A Google search indicates that you can install a deceleration by-pass if the engine vacuum can't overcome SC pressure at deceleration.
