I own a 2008 GT/CS with a full whipple H/O Intercooled supercharger kit, a borla x-pipe cat-back exhaust and the rest is pretty much stock on it. I also have 355 gears. I want to put a camshaft in it for the nice sound and for some added HP and was wondering if i needed to replace anything else on the car so nothing gets messed up for real. Also, any recommended camshafts?

 

i don't think you would need to replace
anything else....

for sound AND power, you might consider
BBR stage 1 or 2.

 

Iff you just want sound the FRPP Hot Rods will work fine but you will need to retune. Any worthwile cam for power you will need to replace valve springs, get a retune and a new set of taller gears. At that point you might want to make some phone calls and find the ideal cam for a positive displacement blower such as the Whipple.

 

whats kind of gas mileage do u think i will be lookin at after the cams? if its worse than 10 mpg dont think it worth it

 

maybe 19 highway, 14 city.....

I'd install a wideband. Running boost without a WO2 is asking for trouble.
