a have a ap1 with ap2 swap planning that turn the motor 8500 8600 rpm?

3.8" I think is good for 14 psi. Don't think you would want to run more than that without upgrading the bearings.

I think the 3.8 is good for 12-12.5?

4" is rated at 12.5 I believe. Sure hope so as that is what I just installed and getting tuned on on Monday.

According to this chart in the FAQ it looks like 4" =12.5 and 3.8" =14 psi. For 9k redline that is. So if you are talking about an AP2 then that is probably right.

at 8200 rpm a 3,5 " can do 13,5 psi
if i turn 8500 will it be ok?

japancrx90

is 400 whp is possible with 3.8 " on a 2,2 that turn 8600

gettin it

Wow, lol! i guess we will find out pretty soon. Im waiting for mase to return so that i can get my injectors, and map sensor and Aem ems installed and tuned. I have the 3.8 pulley from Vortech thinking it was 12.5. lol! But im cool with 14psi.

gettin it

And this will be on a Ap2
