Hi everyone.. i own a 2006 gmc sierra 2500hd crewcab, i recently ordered this cam http://www.compcams.com/Cam_Specs/Ca...csid=1096&sb=2 + valve springs + borla headers.
my car right now generates 276hp at the wheels with just an intake and ecu tuning so can anyone predict how much hp ill get from the headers , cam and springs ?

 

+50rwhp shouldn't be hard to get acheive I'll think your mods will put you at a solid 330rwhp.

 

Borla makes headers? What are they, shorties? If so, I would pass on those unless you're in CA and don't have a choice.

330 RWHP sounds a little ambitious to me, I'd think that the cam might be worth 30-40 at the crank with the right tuning...maybe 315 at the wheels? If the headers are shorties, I'd say another 10-15 at the crank...not sure, I'm not the best at guessing HP numbers...

 

yeah they make headers but its hard to find... what do u mean by CA?

 

CA= CALIFORNIA, he was referring to u using shorties if you were in cali based on there emissions laws. you wouldnt be able to use long tube in CA. i do believe.

 

i am saying 300 on a honest dyno, a "enhanced" dyno will be 315ish...

 

You are correct sir
