I was wondering if a Blow off valve meant for like a turbo say a Turbo xs RFL would work with a supercharger. And also what pulley combo do i need for 9#'s of boost with a v-1 sc trim on a 93 i am running 6 now which is what was with the kit.

What size pullies do you have on the blower/crank now???
i have what came with the kit i am running a v-1 sc-trim kit at 5-6 lbs what about the blow off valve and does anyone run a turbo timer to cool the engine down b-4 shutting it off
Still need to know the exact size blower pulley. The crank is probably the 6.87"

Also think about getting a powerpipe if you don't have one already.
SC-trim comes with 6 inch crank pulley that fit inside the stock pulley. Try a 3.00 blower pulley for 9psi. You don't need a turbo timer on a blown car. If you use a turbo blowoff valve make sure it exhaust air in the intake pipe after the mass-air/before blower.

i heard that mainly the reasone BOV wont work is because most people dont have enough vaccum to keep them closed i have 17 lbs of vaccum at idle i ordered a BOV today its a Turbo XS RFL its huge got it for 69 dollars shipped
the blow off valve will work, but you can not vent it out... you will have to vent it back in the system, like the stock one... I have a Greddy one on my car, works just fine...
