Imagine how much faster that truck could be!!! ^^^^ Not that 12.0 is bad but without being lifted with big wheels/tires.

But it's so much cooler seeing a big jacked up truck putting the smack down on a mustang, TA, camaro etc. etc.

Badass what motor, drivetrain? On twins? What kind of turbos? Trying to get a round about of where my truck should be and what I want out of mine. My setup is a 427 LSX, All Pro heads, holley hi ram ls7 intake, ID2000s with twins on 18-20lbs. I would really like to have a 10 sec truck if I can. Should make around 1100-1200 whp hopefully wishing lol.

12.0@ 112.5 1.80 60ft.
2wd 02 extended cab, single turbo pt 7675 @ 9ish psi.
This was my last outing, I have since added meth and feels like 50+ HP gain after tuning and added timing
