i have 3.73s in right now but when i supercharger my car i want something that will help my car accelerate into the boost faster. Should i put 4.10s in or just leave the 3.73s

Wait until after the supercharger install to make your decision. I would say 3:73.

I went from stock to 3.73's shortly after I installed the S/C. Some go with 4.10's but it is my opinion that for a daily driver 3.73's are the perfect combo. If you are going to spend a LOT of time at the track then 4.10's or better may be "your cup of tea".

I had 410s before the K-B and had to go down to 373s after install. Much happier now. Plus better for the highway cruising.

I've got 3.73's and love 'em. The only way i'd do 4.10's or more is if you dont plan on too much street/highway driving.

Just for reference, i'm at roughly 2.8K rpms crusing at 80mph in 5th gear.

I agree with Paul, 4.10's are probably too much gear for a blown car.

N/A it would be my choice though.

I have 3.31's in my car BTW.....

I have 3.90's in my car with a S/C set up and I love them. When crusing at 80mph I'm still under 3k rpm.

I opted for a roots blower (Allen), with them, you don't have to worry about "keeping it in boost". May be worth considering. I've been getting 27 MPG Highway lately!! Though, I have bought 3.73's to give me a little more response, just have not installed them, yet. I think 3.73 is best "all around", but OGBATMAN's 3.90 idea is certainly a good compromise as well.

I have the 3:73's and think that they are a perfect fit for the Centrifical blowers. Id be a little leary with the 4:10's, yer gonna smoke every damn gear up to 4th(lol).
