Help with Gears, 4.10's not cutting it w/Turbo
#41

When I was first getting started and only running about 5-6lbs or so I went FROM 3.42's TO 4.10's. Had factory 20's 31.5" I believe and a 10.5" vig that would brake stall to 2800ish. I dropped from 9.54 to 8.90 just with the gear swap from one week to the next with the same weather conditions. I know it doesnt make sense but that is exactly what happened. I was only building about 2.5-3psi at the line though. It woke the damn thing up.

Try and find someone with some 31-32" tall tires you can swap on just for a test drive. That will effectively change your gear ratio and allow you to see somewhat what it would be like with a gear change.
