Default 4.10 To 3.73

I have been debating on doing the change. I have tried various calculator to see what the difference would be. They have not really helped. I know my MPH will go up but I am not sure how the ET will be effected. I am running the 1/4 in 11.037 @ 128 now. The 69ft is about 1.78 spinning, it's a 6 speed. Any ideas?

A lot of it will depend on what size tire you are running to man. I'm debating this same thing simply to give myself more gear given that I run a 275/40/17 which is roughly only 25.6 inches tall. That's pretty short. So for me it's either run atleast a 26" tire to completely finish the quarter or drop the ratio a bit.

Are you taking off in first gear or second? Are you close to hitting the rev limiter before the traps?
