Wow - that would almost make the B4 into a stunt machine, I would think.
Is that what you have been riding with? I'll bet it's torquey.
I have not played with my gearing at all.... yet. I posted about this here a couple months ago. At least for Pocono, which is a very tight track (mostly 2nd gear), I'm going to try gearing UP very slightly by going to a stock SVS 44T rear with the stock 14 in front. The problem was if I carried good speed onto the backstraight, I'd hit the rev limiter at the end in 3rd. The entry and exit turns are both 2nd gear turns so to go up to 4th, I'd be shifting 4 times (2 up and 2 back down) on a short straightaway. I'm hoping a few extra teeth will let me stay in 3rd (with more speed, obviously.). I might be totally full of BS but sprocket swaps aren't that hard.
I'll be interested to hear what others are doing.
