how much boost can a garrett .67trim turbo make?
You can run it up to 100psi+ if you wanted to.
Not really. Boost is just a measurement of intake restriction. Psi will change from engine to engine. On my engine of 260 cubes , i can run 30 psi no problem with my gt42-76 . On rajs car he could make more than 22 psi with the exact same turbo. Cubes and head flow is what determines the boost a turbo will put out.
To answer the original question, yes his turbo will go to 12 psi without any problems.
thanks, im kind of turbo illiterate. but im learning. have you ever messed with a blow thru carb? im curious about messing with a regular holley carb and making it a blow thru. what all is different
