Im looking to gain some HP's not sure what the best way is a jacksaft or a pulley Ive seen threads but cant remember. would like to know Im doing it correct thanks
 
The jackshaft pulley will overdrive your supercharger. They can be bought in 5 % and 10 % just like supercharger pulleys. Do you have an overdrive SC pulley?

Underdrives for the water pump, crank and alternator are also available and do not affect the operation of the SC.
 
if everything is stock on your SC, i'd say get the flowmaster cat-back, SCP 3" intake, 5% jackshaft, and some ARP underdrives.

all that should be good for at least 40hp and for about $800. or cheaper if u find some used stuff.
