How fast exactly is redline in 4th and 5th gear?

[TurbLu]

Hey guys,

At redline(7.5k) in 4th gear with a 5spd how fast are we exactly going as my cluster is the analog one and it only goes to 110. Also what about redline in 5th gear?

i think its about 115ish.... put it this way, you hit the speed limiter in 4th gear b4 u hit the rev limiter (speed limiter is about 113-117mph)

supposedly top of 5th (without limiter) is about 180 ish depending on what gears your car is running

to find out exact numbers get your rolling diameter from the tires and gear ratios for the rear diff and the two gears you are wondering about and put the information into this http://www.mustang123.com/calculators/Top_Speed_Calculator.asp

In 5th, w/ stock gearing, I believe top speed would be 157 mph.

tire size affects gearing as well
