I was wondering if there is any options on the sc i can fix up? like can i swap out the pulleys??? and what else can i expand upon on the sc system?

sorry forgot to say its a 07 5.3L ss

 

if you are looking to get it a bit better there are always pully down grade (really upgrade tho) a intake will do a bit of something, but then with more exhaust youd need a high flow exhasust system. youll see a whole different car if you do the pulley intake and exhaust system.

 

What s/c system? You don't have a supercharger if you have the LS4. You can swap out the pullies for the other parts like the alternator, water pump, etc for underdrive pullies that pick up a small amount of power, but I don't understand what you're really asking here.

 

????????????????????????????? S/C?????????????????????? on a 5.3????????????????????
