Assuming the gear ratio is the same and nothing was wrong with the 8... the 9 WILL make your car slower NOT faster. It weighs more and introduces more parasitic loss.blue66tang said:Since you just switched to a 9" not to long ago, did your car slow down in the 1/4 mile. I just put a 9" in mine. I am hopeing to break into the 12s this summer( i said that last year, but i wasnt able to go once.) My current best so far is a 13.4 with 2.2 60'.
