Gears question Hey guys I am finishing up my nitrous outlet plate system, accompanied with full bolt ons and a YANK SS3600. My 94Z has an A4 and I am curious what you guys think I should use for a gear ratio. I am torn between 3.73's or 4.10's. The car is purely a toy/drag car and I am worried that with 4.10s on a 26in tire I will need to shift into 4th right before the 1/4 mile which would be slowing me down. I would like to trap between 110-115 area. Any thoughts/suggestions?
What's your redline? Stock?
I'm going to assume you have a redline ~5700rpm for the heck of it here.
1.) 3.73's, 26" tall tire, top of 3rd = ~119mph
2.) 4.10's, 26" tall tire, top of 3rd = ~107mph
If I am correct assuming your redline is in or around 5700rpm, the 3.73's look like the hot ticket between the two.

Yes as far as I am aware the redline is stock, also I dont think of it to be wise to move it up due to the 150 shot I will be spraying. I am hoping for traction on a 26in drag radial with the bigger stall.

3.73s/3600 stall/DRs/Nitrous/and viking drag shocks will make for a pretty quick car. 3.73s are just right for an auto car IMO.

I was hoping the 4.10s would work out but the more and more I read up on other relatively same set ups as mine, they trap around 110-115 which would put me right in 4th just before the traps. I'm trying to stay in my power band as much as possible.
