How Much Boost?
Hello
How much boost can a Vortech SQ-trim support? I am currently running 7 psi, like all things I WANT MORE. I am planning on building a LS2 402 and I would like to run between 12-14 psi.

I think that you will need a T-Trim or larger to run that much boost on a 402.

. More power to ya, and good luck
. Thanks for the info though. I know I had the S-trim on my 1996 383 LT4 running about 16 psi but it wasn't very efficent at all. I was getting ready to switch to a bigger blower when I sold the car.
