Gears

1997COBRA · 01-03-2006, 05:20 AM

i'm a daily driver but want to spice of my acceleration but not lose too much on gas, any suggestion on the types of gears or gas mileage specs? are 4.10s too much?

thanks guys

I have 3.73's and I get anywhere from 24-27 mpg on the highway...as long as I stay off the throttle!

If you want milage. go to 3:55's for S/C applications or 3:73's for a little more help. 4:10's will kill your milage.

Yeah, but 4.10's sure feels good when you hammer it

Yea they do!!!! On my way right now to pick up some 4:30's for phoenix!

If ya Got the pocket book for the fuel, then go with 4:10's, If your a Broke bum like Most, go with 3:55's.

when I am in the boost I think I only get 8 mpg...

And when I am just cursing I think it is around 10. Because I idle at 40-psi fuel press and when you get on it shoots up to 80.

Its that damn boost-a-pump.

I would agree with Joe (bluethunder) that if you have the money 4:10 are the way to go, and if you don’t then 3:55 aren’t bad either. Good luck.

03-04 Cobras come with 3:55 gears.

oh my God...i feel dumber for trying to read that...thanks aaron.

how do you know what your mpg is when you are in boost? and you only get 10 mpg on a regular basis? your car has major issues. i got 24mpg driving to San Antonio w/ the a/c on and the cruise set at around 80-85mph.

Gears.....I'm getting some 4.10s put in when I redo my rear end in the Cobra.

cmon guys, lets keep it on topic.

cobrapace94 · 01-03-2006, 01:30 PM

I have 3.73 in my 5.0 (rev limitor a lot lower then the 4.6 mod motor) & I think they are perfect. My mileage did not change at all, except when playing around a lot. Since the supercharge I have picked up a set of 3.55's. If I had a mod motor I would go with 4.10's. That is unless you do a lot of highway driving, then 3.73's.

They are averages,

When I get in the boost a lot I only get 150 miles on a tank.

And when I don’t I get 200 miles on a tank.

Those are the numbers that I get most of the time

I changed my first post if i makes you happy.

ok, 170 miles/tank is about 13-14 mpg. 230 miles/tank is about 18 mpg (roughly).

i would go w/ 3.73 gears...those are a good gear for street use IMO. i like the stock 3.55 gears that i have though

Sorry, it sould be 150 in boost and 200 not in boost i was not paying attention.

I got 230 when i was braking in the motor with the rpms at 2000-2500 all the time.

Remember he has a non boosted 97 Cobra, not a 03\04.
