Looking for input lmk . On a gear setup for my imaginary car

If it's gonna stay supercharged I would imagine 4.10's to be a little unethical seeing as the power adder is instant and you would also want the power to last somewhat through the rpm band instead of shifting every 2-4 seconds while spinning the tires. 3.73's seem manageable but I terminator owner can most likely verify. I'm just thinking like an engineer lol

I'd stay stock if you plan on doing anything to the supercharger ( port, pullies ) stock is 3.55 is im not mistaken. but again, i'd wait for a termy owner to chime in.

If anything, 3:73s.
I had them in my 03 and loved them.

My terminator swap in 97 has 4:10s. Once the swap is done ill see how it is. I heard from a few that 4:10s could be good in a termi but then again they weren't termi owners or never had any knowledge on that kind of gear in one..

I have 373 in my cobra and they are a very good gear ratio. I do have a viper 5th and 6th in my t56 so on the freewy I get great mileage. I had 3.55 and the 373s did make my car faster in 1st-4th.

I have 4.10s on mine. Ported blower, 2.76 upper and 4lb lower. Don't Fear the Gear [patriot]

This really comes down to, hows the cobra going to be driven? street? drag?

For me, I mainly street use my cobra with pulls here and there. I love my stock gears (3.55) with 5xx+rwtq.

But if I was to choose between 3.73s or 4.10s. I'd go 3.73s for the way I drive the car.

LOL at JR though!

Suprised no one has mentioned 3:90's that's the most common gear swap for cobras. 3:73 is not that big of a difference from 3.55 garantee you won't even notice it its a waste of money in my 96 cobra I went from stock to 4:30 best mod I did

2.73 yo

I'm doing 3:90s

Actually the stock 3:55 rear is bullet proof so if it's a street ride I'd leave it alone.

have 3:73's in my 03 along with built IRS, love them. went with 3:73's just in case i want to add more power down the road. making 580/515 SAE to the rear wheels currently.

for roll racing and low rpm on the freeway and gas mileage leave the stock 3.55s. Now with that bullshit out of the way, if you want to go faster at the track and on the steet put 4.10s in it. Dont even bother with 3.73 or 3.90. If the blower was not ported i would be even going up to a 4.30 gear, i dont believe in the whole twin screws dont need such a steep gear becuz they already have so much low end torque.2nd thing, never kill the gear becuz you have no traction, look into the tire and suspension always. To many times i hear this and see this rookie mistake. I recommend even 4.10 with a whipple 2.3 up to about 580rwhp considering whipple cars will have a shift point of around 6700rpm minimum and i know what they trap. Go 4.10s hands down.
