12 Second Crew Cab 4x4 Hits the Dyno!

[vettelovralexand]

Results: 515 hp and 487 lb-ft only pulling to 6k! (dynojet dyno)

Mods: Roush TVS1900 with 10% overdrive lower pulley, 219/234 BTR specd cam, PRC stage 1 LS6 heads w BTR platinum springs with Ti retainers, Kooks 1 7/8 headers with catless y pipe, factory NNBS flex fuel pump, and 6.2 flex fuel injectors. Tuned for 93 octane by Blackbear performance

 

They started to fall off because we were running a lot of times back to back. The truck's stock 60k all terrains couldnt hook on the dyno at all. Wound up with 600 lb in the bed and double strapped with 25 psi in the tires to make the pulls we got.

 

Here is a video from the highest power run at Hoosier Street Cars in Lafayette, IN:

Damn everyone is taking their vehicles there. Just had 2 friends have cam work done and another one going there.

 

Mike Norris in indy (Plainfield) also had a dyno if you don't want to travel as far

It was an event that one of my friends was involved in, and I wasn't busy so I drove up and made my 3 pulls. I ended up with the highest of the day by about 7 hp over a 5.7 GTO with headers, cam, and 125 shot of nitrous.

 

The dyno operator was really impressed considering it was a truck on all factory drivetrain/wheels/tires making a 3rd gear pull instead of 4th.
