Nope.. Different car.

So with that said, I don't think it'll be a problem to see ~140+ mph.

IN 4th gear? with 4.10's

 

[DRock]

it is ome where in the 120 to like 130 range....somewhere in there.

Yes. Most people don't realize that you're not ever going to be limited by gearing in a S197. Aerodynamics are going to shut you down way sooner!

Granted I've got 3.55s but I hit about ~120-125 mph in 3rd gear!

 

[navyman8903]

I think it is 121mph with 4.10's(with my engine I can rev to 6500) I am using this calculator: Ford Mustang: Mustang Tech: Calculators & Decoders: RPM Calculator

With the values for a t3650 out of a 03-04 mach 1. From wiki, Tremec TR-3650 transmission - Wikipedia, the free encyclopedia

 

[navyman8903]

But I don't know if that is correct for a s197

 

[Marc S]

129.19 MPH at 6600 with a 26.98" tall tire.

Does anyone have numbers for an automatic?

Stock size wheels

In 4th they both have a 1:1 so with the same rear gears and wheel size they will be the same.

 

[Scott2001GT]

i would like around 116 to 120 at 6k...didn't someone say your stock tire hieght is taller then my New Edge? I have a auto with 4:10s and can do 112 at 6300 or so in 3rd with 18s on 35wall

 

[cuartza]

with 20's and 4.10's ive hit just shy of the 120 mark in 4th racing down the autobahn. pushing it, but it was done!!

 

[Rusty05]

3.55's top of 4th is around 135-140 margin.

 

[bigpappy33]

with my 4.10s i am topping out 4th around 120-125 mph.

 

[06Black5spdGT]

with my 4.10s i am topping out 4th around 120-125 mph.

I love your rims.

 

[GT33]

with my 4.10s its about 135ish not really watching it at those speeds lol> but def lower than when i had my the stock 3.55. And im on a 28.8 inch tire.

That 28.8 allows you to see the 135.

Wow - only 2 of you guys actually mentioned tire height which is VERY IMPORTANT in calculating the proper gear set-up on your car. Most of you guys should be able to see around 128-130 mph on 4.10's through 4th carrying the traps and depending on how good your train is and where you can shift at - its possible to see even higher.
