ATI ,if you get 10# on a 9 4to1 compression motor, what would the boost be on a 10 to1 compression motor.

As far as motor goes it's the H&C that'll affect boost, bigger cam (w/in limit of a blower cam) and better flowing heads will drop boost but power should go up

It doesnt mean it will go kabooooooom, it just means that the tuning has to be dead on. If you get any Knock your engine will most likely end its life.
Higher compression, higher boost, less safety margin.
There are a few guys here in colorado that are running 10-12lbs of boost on 10.5:1 and even one guy has 12:1 compression and is running around 10lbs of boost. He has had his setup going on two years with 20k miles and no problems. It might be the altitude not sure, or maybe he just has one built motor
