If he is putting down 2.0 60' times what makes you think he needs more seat time? That's pretty damn good on street tires, and after the launch all one needs to do is hold down the pedal and keep the wheel straight.

Fwiw I ran a 13.2 at 109mph with a DA of 5500. I have Intake,pulley, and tune. I'd be happy with a 12.5 with a good launch at a better track
