I looking into buying a new pulley for my 06 ss/sc...i wanna buy a 2.5 or 2.6 but i heard rumors that you cant get much smaller than a 2.7 without porting the super? is that true? PS Im getting 60# injectors and a reflash just wondering about the pulley..thanks a bunch

make sure to get cooling mods if you run smaller than a 2.9

running smaller than a 2.7 requires porting?

i just recieved my 2.79 to swap onto my stage 2 hub....will this size be safe with my stage 2 tune?

Cooling modds bro. Dont forget that... You hairblower thows alot of hot air, especially with a 2.5-2.7

X2 on the cooling mods. right now i'm running a 2.6 and the boost isn't as high as it should be and there is a slightly noticable power loss at higher rpms. with cooling mods my boost will jump and the power will stay through out the rpms. next on my mods list will be a cobra heat exchanger & dual pass. also be sure to get 2 step colder plugs.
