that's what makes these events fun. A legit 11 second car can get killed or kick ass, it depends on the gearing, powerband, and traction. Ger it for top end, you bog out of the hole. Gear it for the holeshot, you peak out before the end. It's pretty tricky to calculate. TT C5Z06s are in the 170-180 range. Over 160, aerodynamics comes into play as well. It takes a lot of power to push a car quickly from 140-170. Get a light car (I am at 2914 with cage) and you must let off throttle very carefully at 170.
