you can't compare different cars,,,some run better than others,, last week 4 of us went to a 1/4 mile track,, two roadsters both with 181 pulley and the same tune, same intake, one ran 12.5 the other ran 12.7 they got about 5 runs each all about the same for each car,, and we also had two coupes there , both with SC pulley and tune,, one car ran 12.6 5 times in a row and the other car ran 12.2 for 5 runs ,, so you need to test the pullys on the same car and hopefuly the same day, good luck,, jim
