How Quicker with 4:10 Gears ?

[CAJUN C4]

Approx. ET improvement when going from 3:45's to 4:10's. No other Modifications.

4:10 gears are pretty low. Thats 1/4 mile stuff alright.My question would be how is this going to effect highway driving? Rpm's at 70 MPH?

I know it caused some issues with the older cars I have owned.

May not be a problem with newer cars.

It dropped my Trans ratios by 15%
1st = 3.16 (2.68)
2nd = 2.12 (1.80)
3rd = 1.52 (1.29)
4th = 1.18 (1.0)
5th = .89 (0.75)
6th = .59 (0.50)

At 75 MPH I'm at 2,000 RPM in 6th. I still get 27-30 MPG at 70 MPH.(Depending on Wind Direction)
I was just wondering what it did for ET vs Stock

You now have a traction problem due to the increased 1st gear torque so you would need DR's to optimise traction.
Depends were you are in the rev range crossing the finish line as well ; you may be in the bottom of 4th instead of top of 3rd
