How much time did you knock off your 1/4 with gears?

[96Forged281]

State what your gear ratio was and what your 1/4 time was and then what your new ratio is with new times.

Im pretty sure the 01 GT 5spd I have has 3.27s

Im thinking of going with 3.90s

10.3 in a 1/8 to 9.8 when i went from 3.08's to 3.73, then 9.8 to 9.3 when i went from 3.73's to 4.10's. Its worth every cent you will spend!

I went from 14.5 to 14.0 with a set of 4.10s. I had no other mods and was running on bald stock tires.

10.3 to 9.3 when i went from 3.08's to 4.10's Was this using nitrous?

2/10ths in the 1/8th mile alone.

I would argue that on a manual transmission, you shouldn't gain more than .1 or .2 if you can drive well. Factory gearing is certainly cabable of 2.0 and 2.1 60' times, even on street tires; yes, it takes some practice to do that. Gears simply make it easier to get good 60' times because you don't have to play with the clutch so much. In my NPI with street tires on an average track with little to no prep, I get regular 2.1s by launching between 3000 and 3500, and slipping the clutch. I've even gotten a few 2.0s.

The biggest advantage I see to changing the gearing, is to make the gearing work out as you are crossing the line. On my NPI, I have to shift to 4th just before the finish line which hurts me. If I hold 3rd, it costs me several tenths and about 3mph. I'm also leaving a couple tenths on the table shifting to 4th so late because it is at the top end of the track. I make the shift to 4th and I end up crossing the line at 4000-4200 instead of 5k where I'd like to be.

The best gears will make your 1:1 gear (4th on a 5sp) rev to 100-200rpm above your peak horsepower as you are crossing the finish line. IE, if your peak power is at 5500, then you want to cross the stripes at around 5600 in 4th.

i must not know how to drive.... i went to track about a year ago, with my 373's and all my 60' were between 2.6-2.9 and my 1/4 mile times were around 14.9-15.3's

 

[96GTstang46]

Yea maybe.... jk
Your car stock runs a 15.... and a 2.6- 2.9 60'? wow.... dump that clutch and get moving!

you should be able to get a 2.10 2.0 pretty easy...

you're not gonna hurt it Launch it!

 

[CobraRed_96_GT]

I hit 1.9X's still being NPI (except for intake). My best Et has been with a 2.0 60 - but i've hit 1.9's a an okay amount of times on 275's.

So knowing a 01 GT 5spd, just what gearing is it that will put me across the line around 55-5600?

I think I may just go with 3.73s so my gas mileage doesnt suffer too bad. I do alot of driving 65+

when i was at the track the car had : cia, udp's, o/r h and cat back, 373's and my short shifter , oh yeah and a 275 street tire with 22lbs of air.....

 

[billfisher]

i went from 9.4 to 9.15 going from 3.08 to 3.90. miles per hour stayed the same.

 

[NX281GT]

I went from a 9.4 and a 2.20 60' down to 8.8 with a 1.96 60' going from stock 3.27's to 4.10's and 315 Nittos.

 

[NX281GT]

i went from 9.4 to 9.15 going from 3.08 to 3.90. miles per hour stayed the same.

How do you like those Hoosier's? I bought a pair of Hoosier 275/50 DOT's on Draglites and front skinnys but I haven't tried em' out yet. These Nitto's work okay, I seem to do best at 20psi with a 5-7 second burnout but I'm still rolling it off at 3k and working the clutch a bit to keep traction. Have you experimented with your DOT's at all, burnouts and pressure changes?

 

[joshheat25]

Went from 14.2 to 13.7 Gear change was 3.27 to 4.10 in an auto

 

[andy13186]

I think 3rd gear with stock gears redlines at around 100-103 mph, should be perfect for a stock 1/4 mile end time

 

[Cobra123089]

red line in third with stock gears i could hit 110

 

[BurningRubber]

I only hit about 110mph in 4th before I am at the rev limiter now.

Its set at 5900, so if I ever start trapping more than that I will just raise it a few hundred RPM.
