Are these the right pulleys to up boost a bit??

Already running S1.SE fuel system etc.. + this air to air kit and blower upgrdeded with Si trim.

I've got the Tbat pulley on the front, was there something else needed on supercharger side?

Now I'm seeing something about head lift somewhere? do we do ARP headstuds to stop it or?

Cheers guys!

If you are still on a stock motor it is the rods/pistons that you need to worry about first. Once you get to 700whp you will need to address the head lift issue. Above 700whp it starts to get expensive. At 700whp you will need at least ARP L1900 or ARP625 head studs. A high quality MLS gasket will hold at that 700whp.
