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!

The 3.47 pulley you'll be installing on the jackshaft on the sc side is a different offset than the stock 3.2 and will stick out towards the motor approximately 1/2" which mean it won't be aligned with the sc or tensioner pulleys. You'll need to add spacers on the sc shaft and tensioner pulley to make up the difference. Assuming you already have the 9lb pulley on the jackshaft (serpentine side)l you'll be spinning the sc at close to 63000 rpm. Don't expect the oil slinger to last too long.

Boost wise, you'll also be in head lift territory. I'm not sure that just adding ARP headstuds will cure that.

Also, what fuel are you running? You'll be at a boost level where e85 may be needed.
