Guest Modified17 Posted September 14, 2012 Report Share Posted September 14, 2012 Looking To race here on the 22nd. Just wanted to ask what will be a good final gear to run there? Crate or claim motor? And what rpm do you want your claim motor to turn? I have the same question. Need to know what gear to run in a sportmod. I would like to pull up there, but don't want to go just to run last....Playing around guessing at gear set up. It's a 6 Hour pull for me. RPM Range 6400-7400 Link to comment Share on other sites More sharing options...
gen11 Posted September 14, 2012 Report Share Posted September 14, 2012 My math tells me a final ratio in the 6.25 range for 7000 rpm. I got a B. lol I did get an A in geometry though. Anywhere from 6.0 to 6.30 should be competitive. Make sure you guys give me a thank you wave if you start passing me. note: That ratio is for claim motors. 602 crate ain't gonna like it.

DonJuan Posted September 14, 2012 Report Share Posted September 14, 2012 I agree. I have only run Thunderhill once and it was with a 6.22 final ratio. I was turning 6800 RPM at the end of the straights. Link to comment Share on other sites More sharing options...
