Question What Gears do you Turbo Stang Owners run???

I was wondering what other turbo stang owners, modular motors 4.6L SOHC & DOHC are running for differential gears?

*What gears are you using and why?
*Have you driven the car with them?
*& If you could do it again what gears would you go with?

Im currently running 3.73 and Im thinking they might be over kill.

My car has Plenty of TQ in the mid-range and I think it might be able maximizing it by having taller gear maybe a 3.55 or 3.27, It would keep the car in a better power range for longer, Ride the TQ-Band. I think 3.73 might be to much.

I was thinking Im might need to go lower Because:

1.) Generally Its a necessity for a blower car to have gears to get the motor into upper RPM band because thats where the boost is, But seeing as Im turboed I do not have to worry about that particular situation. (Full Boost 3300RPM).

2.) A Turbo needs load to create boost and shorter gears make it harder for the engine to get a load (IE) harder to get boost.

3.) Gears multiply TQ and seeing as Im making more than a SC Cobra I do not need to worry about the gear multiply effect.

For racing or automatic tranny= 2.55

For street w/ T5= 3.27

For Road/economy= 3.08

The 3.27's are probably the ideal all around. I use stock 3.08s on my Cobra and don't plan to change them.

I have 3.08s, they work fine with the turbo, but they are a ****ty gear for stop and go driving, and 5th gear is pointless unless I'm cruising 70mph+.

You dont need gear with the turbo.

I think 3.55s are optimal with a t5 or tremec, because it lets you cross the traps at a good RPM in 4th.

for C4/auto, I'd keep whatever stock gears you have.

Why, care to elaborate?

The lowest I would consider going is back to the stock 3.27.
Im kind of hesitant though, Im trying to decieding between 3.27 or 3.55.

Im currently running through the traps @ Almost Redline which most HARDCORE Owners would say is perfect but Its a street car first and a strip car 2nd.

I'm using 3.55 because my car came with em. I'm running the stock all-season tires that saleen uses, 265/35-18 Pirelli P7000. I lose traction in 1st, sometimes in 2nd, and somtimes in 3rd depending on the road and how I shift. I think with better tires, the 3.55s would be perfect for my application. Personally, I wouldn't go any higher than 3.55 since I already have traction issues and my car is a daily commuter

IMO the losing traction argument isn't that great. I have 3.08s and lose traction easily in 3rd gear with the street setup thats netted me 1.80 60 foot. You aint gonna have street traction with any gear.

The reason I don't like 3.08s for stop and go driving... they just arn't the right gear for the car. Only reason they're in mustangs is for fuel economy purposes. From a stop, you have to feather the clutch too much, if you are putzing through a parking lot, the car will jerk unless your foots on the clutch. Plus 5th gear sucks once you have heads/intake since the power bands high. On my car anything less then like 70 feels like the rpms to low to be in 5th. So its just an akward rear gear. I think 3.55s are a good compromise, and have enough range to trap 120s comfortably in 4th.

Just curious, what tires are you running and how much power are you putting to the ground?

I'm running the factory 3.27's.....can't really justify swapping to 3.55's, but if I was going to get gears, they would be 3.55's. 3.73's are a bit much for the 2v - but might be acceptable for the additional rpm's you can pull with the 4v.

I'm running 3.27 in a pushrod twin turbo set-up. I cut a 1.66 on Drag Radials.

Two turbos and a carb...

Vegastang made some good points regarding the 3.08s. I have them in a 95 Cobra and havn't really noticed the things he mentioned, but then the Cobra is optimized for low-mid range torque- perhaps the GTs are different in that respect. The only problem I noticed is that 5th gear is not the best for mountain cruising- at least that was not the case before the twin turbos went in. On the other hand, the 3.08s and overdrive have been very good for freeway and high speed use- they provide good mileage and minimal wear on the drivetrain. I generally get ~330 miles per tank normally, better on long trips.

Just keep in mind that turbos need to work to produce boost- I believe the tall gears help to bring boost earlier and prevent unwanted tire spin to some extent. If you are going to use tall tires, get 3.55s, otherwise go to 3.27s.

The important thing is to consider how fast your engine normally runs most of the time and when your turbo boost comes on. The 3.08s give me 2200-2300 rpms at cruise (80 mph), I get full boost at 2300-2400, so the combo works well without having to shift down for a quick burst of torque. If the boost didn't happen until 2800, 3.55s would be preferable.

Im running 4.10 gears which i put in when the car was stock. Car is an auto so NA the car needs at least this gear. With the turbo however im waiting till i change my rear before i swap them out for probably 3.55 or maybe even back to stock 3.27's. I tell you what though my car is a daily driven car, Im in NYC so no stranger to traffic and bad driving conditions and the 4.10's when your not mashing the gas pedal arent that bad. I drive it everyday without any real problems. I have 555R's in the rear. Dont know exact hp numbers yet, dyno this weekend, but the car feels real stong when i get on it.

2turboz: i have tfs heads/track heat intake, so my powerband is alot higher then stock. when i had stock stuff, this problems wasn't as noticable, like you said the low ends not bad stock.

sizz: my car was probably making ~370rwhp, I have 245 nittos on 16inch wheels. yes it broke tires loose in 3rd gear with 3.08s with stock heads/cam/intake. part of this is because in vegas theres not much rain, so the roads are greasier.

2turboz makes a good point, the 3.08s will get you into boost faster because of the higher load.

my main point is that on my car, 5th gear is akward. if you do alot of highway driving with no hills at 70+ than theyre prob fine.
