Re: 3rd gear?!?!

Welcome to the world of being underpowered. Haha.
Slap a steeper gear in there and it'll help a lot.

He's talking about a 3.73 or 4.10 gear

Edit: it's cole so he's talking about a 4.10 gear . I don't think he knows what a 3.73 is lol

But then again I only have cai and 78mm tb/p and my car pulls like raped mule in third...

Haha. What is this "3.73" you speak of? :p

I was referring to the gear ratio in the rear differential, OP. The steeper the gear the faster the acceleration. Stock GTs of our years come with a 3.27 gear ratio which is a decent driving gear for MPGs but it falls on its face in third gear and above. Steeper gears like 3.73, 3.90, and 4.10 provide much greater acceleration at the cost of a little less drive ability and mpgs. Gear ratio is essentially the relation between how many times the driveshaft rotates per every one revolution of the rear tires. So a 3.73 gear means te driveshaft will turn roughly 3 and 3/4 times for every one rear tire rotation. The more the driveshaft turns per tire revolution, the higher work is being done by the system therefore less energy used to accelerate. Less energy means more is applied overall so it acts as if you just added 50rwhp to your car(at least it did with my 4.10s).


Now that's a way to cure your "dud" acceleration.

If your car is not accelerating because there is an actual problem you may want to check for vacuum leaks and/or clutch slippage.

Yeah that's what I wanted new gears but idk what I want to go with either 3.73 or 4.10, I use my car for dd so I think 3.73 would be best right?

Haha, check both the links in my signature. They both talk pretty extensively on gears.

if you want my opinion then 4.10s are awesome. You only turn roughly 100-200rpm more than 3.73s and only 400-500 more than stock 3.27s. You lose roughly 1-3mpgHWY and typically don't lose any city mpg and can actually get better mpg in some cases.

I'm always going to be pro 4.10. That being said I have not driven with 3.73s so I can't comment. But like I said; check out the two gear links in my thread and make your own call.
