In the past I've ran everything from an 8.6 to a 10.12 with a Winters, that track will really fool ya, when it was a higher bank, you needed a 10.12 just to get up off/out of the turns, and 3-4 was a buggar, you really had to diamond it a lot, to get up on the front straight, then what RR and stagger you runnin, that's a big figure also, big difference between a 71-74, or a 68-69 RR. A 9.1 will keep the Rpm in a safe zone. Ya gotta start somewhere, but don't expect it to be the same gear next time. Bob
