always faster

Doing a custom blower cam so i will install a stock size PP sfi damper.Car will be turning 6700rpm or more if it can handle it.Setup in sig.

With 11:1 cr i dont wanna pass the 9-10 psi mark so...

3.6 or 3.8 pulley ???


Also still need answer in my other thread:

stryderss

well if your running a stock size crank pulley and running 11-1 a 3.6 will net you about 10psi

^^^^^. He knows because he just got done doing it.

Keep in mind camshafts will affect boost level any thing that affects the engines VE will.

So to the OP if your engine happens to be a little more efficient or less efficient than stryderss' engine combo then you may make a little more or a little less than he does at which point, I'd compare blower impeller speed at that time. (Assuming you are running a stock size crank pulley)

Already got a 3.6 on the blower.

Since i was ordering a big bubba bov upgrade kit, i also ordered a 3.8 and will begin the dyno with this one and see what it does.If im not happy with the 3.8 i will have the 3.6 in backup

Thanks
