when i had 3.73's, underdrive pulleys, prochamber, 3 chamber flows, cold air, i ran one from a dig except i didnt launch i just rolled out because i did not think he was going to go... he went and i chased so he got about half a car jump on me, by 110 mph he was about 2 and a half cars on me which is not bad considering it has 280 hp lol, also consider that i was not that good of a driver then (first stick car), his car was an auto
