Kind of a loaded question..... There are tons of things that play into run time. Ambient temp, humidity, fuel and nitro content, elevation, track conditions, drive train efficiency, clutch, carb inset, traction available with the correct tires installed on the car, pipe and header, and mostly how you drive it....


A fully broken in motor properly tuned for the weather and location, with the correct pipe and clutch on a car with the correct set-up, driven smoothly ( like most pro drivers) should make around 10 minutes. The same set-up with a normal person, will probably be around 8 1/2-9 minutes. All things being equal, minus the driver that is..


It would be safe to say 8-9 minutes.
