3.08 ford racing gear set with rebuild kit.
Misc doodads.

Merry after Christmas
You're gonna put a 3.08 rear gear in your car? Are you planning on participating in the Silver State Classic ?

I now know that even a 3.55 is a little steep w/ a 4R70W....(considering that my first gear is like a 2.85:1) But when I get that thing going fast enough to consider putting it in 4th, the RPM drops down nicely to 2k.......What gear do you use currently?
 
Currently has a t5 with 3.73 gears. Engine is done making power at 5k. My power band is from 2.5-5k for most area under the curve.

With the 3.73 I need to shift into 4th well before the finish in the 1/8. I'm hoping the 3.08 will let me stay in 3rd.


First and second are crazy short with the torque I'm making, I also want to lower the highway rpm so in town Im not spinning 2.5k in 4th at 45mph, and 2.5k in 5th at 70mph.

Too big of a step IMO....3.25's or there abouts?

This is before the timing issue has been fixed
 
I used a few rpm calculators before I made the decision. 3.73 to 3.08 is about 400rpm with a 28" tire.

Then,.......Why do it?
I went to the same calculator,..and I concur. About 400 RPM. It's the difference between 1811 RPM, and 2193 at 70 MPH.

Is 1811 RPM at 70MPH even in your torque range?
 
What make the AEM so much better ?

One thing for sure is that our cars will always find something for us to stay busy with.
