We didn't build this truck, it just came in for tuning. Figured it would be neat to share as there aren't many of the SLP supercharger kits out there! SLP uses a centrifugal unit. This truck also had Kooks headers on it as well. Ended up at 453 rwhp & 461 ft/lbs tq with the factory pulley that comes from SLP (about 7lbs if I remember right).

It was hard to get a decent pic of the head unit, sorry. You can see it hiding under the piping here,

 

Nice graph. What do they dyno stock?

 

That should make a nice sleeper!

 

That's not much more than the 5.3 with a maggie/kooks headers you also posted, I'm surprised there isn't a larger gap. How is the fuel system holding up for the 6.2 with power?

 

I have a 2011 Sierra Denali AWD with a Whipple Supercharger, Dyna tech headers, free flow cats, Corsca exhaust, 4:11 gears and Jannetty Racing Tuned and it went 12.71 @ 107.97 MPH

 

Ummm ok, I guess. Thanks for sharing

 

^^^^ lmao beat me to it
