so i went to the a local speed shop and didnt know what size pulley to buy so he talked me into a 3.33 pulley so he said he had a used one for 40 bucks. i bought it the pulley was not marked in any way and it measured 3.25. wouls this be too small of a pulley with a power pipe and v-2 vortech?

lidio. lol

and yea that is to much psi non intercooled

he said it is good for 11-12 psi. is that true?

anywone?

thats absolutely incorrect, im running a 2.87 pulley and im only making 10 psi, i have a precision intercooler so i doubt 3.33 will make 11 psi

do you have a vortech?

gears94gt

yes i have a s-2 vortech, pushing 436 hp, 462 tq, it was detuned a little to be on the safe side, some people might say its a ticking bomb but it was tuned by scott beer from deerfield beach fl, he said it can safely push 450 with no problem i just did not want to go that far.

I think every car is different. Because im running a 3.12 on a sq trim intercooled and im seeing about 10-11psi. i also run a power pipe.

so what psi would my car be at with a 3.25 pulley?
