Dyno Guesses & Bench Racing Forum - my cousin thinks hes sick in his 650i bmw he wants to run

To be honest im kinda scared he says he launchs real good with the m suspension and its pretty quick all the way up but i dunno my TA got some balls for just having LTs and duals on a stock stall....what u guys think it will be a good 1

The 650i can run mid-high 12s from the factory. I think he will win.
