Man go to work and 2 pages go by..
Yes I did re adjust my ratios(I have been racing for a while)But on that note I did not change the final drive ratio: IE. The "old" pullys with a monster stock i was in the 7.15 range,with the 1.77's I was in the 7.15 range.I race parking lot type tracks/asphalt.So rollout is not used..at least by me for rubber tires.On the 19 winds,depending upon the "type" of motor I was gearing in the 5.9 to 6.25 final range.
