CHRGDUP Denali
 

Been on here a while and haven't posted much so here is my official build thread.

Truck is a 2008 GMC Sierra Denali 2wd 6.2l/6l80e. Bought it stock a few years back and have gone back and forth with plans for it. I original lifted it (I know, lifted 2wd :bang: ) but eventually put it back down and put money towards supercharging it. Truck is currently bone stock (yes, no headers, cai, etc.) with a supercharger. Magnuson TVS1900, only upgrade I've done for it is the fuel pump, I used a flex fuel pump. Runs great but of course I have future plans for supporting mods. I will update as mods continue. Goal is to have truck for daily driving and towing that will put a beating on camaros, mustangs, etc ... which I have somewhat already accomplished. stay tuned.

Nice truck! What kind of power did it make with just the supercharger on the 6.2?

thanks! I haven't dyno'd it. I went to the strip yesterday to get a clue of where it's at and ran 12.98 @ 104.87.

Damn....I need a blower, nice time!

thanks and you definitely do! I never want to drive another vehicle without boost.

How much does she weigh?

google says curb weight is around 5200

You should have around 500 rwhp horsepower.

yea I was thinking mid 400s. I think I'll definitely be at 500 when I do supporting mods. exhaust stock manifolds are choking this blower. cam, vvt delete, ported ls3 TB, headers, injectors etc are on the list.

I think you'd be surprised how little the exhaust manifolds itself matter. It's more about getting the air into the supercharger and through the cylinder heads. There is a reason why CTS-V's, Corvettes and Camaro's made the power they do with cast steel manifolds.
