A number of reasons, once been to drags once, my car is a a manual, I was in full street trim with street tyres at 36 psi etc, the wagon on that day was 1908 kg with me etc. Don't look at the time, look at the MPH I got, 120 mph, good for a low-mid 11 with traction. I no longer have 350 rwkw, have to update my website. I now have a 427 (7 litre) with a small cam making 320 rwkw, but a mountain more torque every where, 860-915 nm across the entire rev range.
