10,000 miles on the car. Nothing broke yet (knock on wood). About 20 11.99 passes or better. About 60 passes down the 1/4 mile all together. fixing to have to change the clutch. This is my only car. :)
I know of some gt's using the tnt kits. Nx kits are rated at the wheels but i dont know what the hell tnt kits are rated at. Ive seen a tnt 75 shot put 125 rwhp to a car and tnt 150 shot put 200rwhp to a car. Those kits are underated. And ive seen demolished engines because of it.
