Ok guys,

My 04 GT at 80mph I'm running at 3k RPM. What gears do you think I have? I got the car used back in Nov. I'm goingto put a Supercharger on it. I like to know if I need to change the gears too.

Thanks

Thats a great question...but in what gear? 4th?

I'd like to know as well, since I bought my car used as well. I'll run a little test tomorrow.

Duu, my bad!! It's a auto with O/D on. So 4th.

lol, 5th. I am pretty sure that I have stock gears and mine is at 2k at 70mph in 5th gear, not sure about 80 so I cant help you too much.

You more than likely have 4.11's if you're running 80mph at 3K in od.

Damn, you provided all the info to make me look stupid while I was typing my post

So when I get the Supercharger do you think I'll need to change the gears?

That's a question that will get you all kinds of opinions. I think 4.11's are fine with F/I cars. I'm running 3.73's and I'm not going to change them when I go F/I.

I't will be fine.

Humm, I rost the tires now, its going to be bad when I get it put on. I was thinking of going down some.

I'm not a car guy I raced Super Bikes for 5 years. I know all about bikes, but 4 weels not so much.[sm=sigh.gif]
