hey all, i have a vortech sq trim supercharger and want to add an intercooler and a 12 psi pulley. a friend told me of a site, lethal performance. would anyone recommend there stuff? also when looking for a pulley do i look for them under 12 psi or do they go by sizes? like 3.33"? will i also need a new belt? and one more question, would it help to upgrade the plenum intake and throttle body? any info would be great guys!!! thanks for all the help.

i see some other posts and i understand that the engine setup will make the psi different so i have a stock block with a power pipe 42 lb injectors and cobra fuel pumps. so with an intercooler, and larger intake plenum and body will something like 3.12" pulley work? do they say sizes on the actual pulley? i ask cause im really not even sure what size i have on right now. thanks guys and sorry i seem so clueless. im so excited to finally have some extra money to do some upgrades!!

yep, pulleys are sold by diameter, not actually boost # because each combo will be different. A nice intercooler and smaller pulley with a tune will be a nice upgrade, along with a nice throttle body and plenum setup for sure. Dont forget you will need upgraded bypass/blowoff valve as well

Hi, 97stanger,
A Q. for you as it seems some experience you side.

I have an 04 svt 4.6 all factory. Looking for the correct pully size that would add boost.
Have heard of conversion kits, but not credible info. Any info is really appreciated.

A smaller blower pulley than what u already have, or a large crank pulley than what you have. A quick internet search will net u all the information u need as far as pulling a terminator. As common as changing socks everyday for those cars.
