3rd gear 7at question
 

Is there anything i can do to rev out 3rd gear more on the 7AT? Once tuned, I might raise the rev limiter to 8k if it still makes power. Right now, third goes to 80 and I was looking for about 90-95. I havent seen any FD's that go below 3.3(stock 7AT) and suprisingly google was no help. PS idas about my 7th

thanks

Why?

And you don't want to raise the limiter if you intend on going past 7500 often. The oil pump will die and if you're on a turn you'll likely oil starve

In my 5.0 I went from 3.73 to 3.31 to stay in the power band longer down the 1/4...even with then % decrease in acceleration I managed much better ET and trap. Guy were either doing 3.31 or 4.10. 4th in this 7AT is weak....

An extra 500RPM's isn't going to get you 15mph in that gear. I'd leave it alone if I were you :twocents:

I agree, anyone heard of any FD?

the current ratios for 1-2 arent too bad

My third touches 95 :/

you can try a 3.90 FD, Some guys go 4.08's but I think 3.90's for us auto guys. I'm trying to change both on mine. Still looking for a set for the front

95?? Thats great! Whats your final drive? My 3rd tops at 80... Crap

I agree the FD on the AT is lacking in the upper gears. I believe 4th is 1:1, which leaves 5-7 as three overdrives.

The 4.08 redefines the performance of our cars. I have tons of power and torque through all seven gears now. Upgrading the diff is a pricey mod, but a game changer in terms of power availability.

I don't track my car (or drive it daily) but my guess would be that I could get through the quarter in 4th or even 5th gear with all the available power the car offers.

no, 1:1 is still the 5th gear.

my FD is 3.36 :( . Looking to go 3.90's but need to find fronts as well. Just saw that my front diff is a F160A, What the hell is that ! If I can find if the older Skylines use this maybe I can find gears. :)

I can see how 4.0 would help out in 7 speeds, by any chance do you know what your 1-2-3 gears top out at?

I wish my 3rd toped out like yours... Is the same 7at as in the g?

No 7AT back then, just the 5AT.

Yes it is, but I'm not stock :)

Ahh ok thanks

So if we have the same motor and tranny and you have shorter gears, how are you reving 3rd to 95?:confused:

It's called getting Tuned. :-)

For what said, making more power :driving:. I'm trapping 105 MPH at track. 3800 LBS AWD sedan :)

oh i know all about tuning, but hes bolt ons...not built (from the sig anyway)....if at 7500k my 3rd is at 80....then how does a tune mechanically overide the physics of gearing? He would have to be redlining at like 10k plus.....UNLESS im missing something....LOL im confused

when I was making 380rwhp and when i was making 445rwhp my 3rd gear always toped out at what my final drive allowed

Power has no impact on gearing/speed. All it's going to do it accelerate you there faster.

I'm making 510whp over the 262whp when it was stock and all my gears/speed are identical to the day I drove it off the lot. Unless you change FD gearing or RPMs it'll be the same for every one else.

Yup thats excatly what im saying...
