I was out in the Mustang Sunday night having some fun driving around with a guy from my unit. He kept asking me what the car tops out at. It was around 1am and there was noone on the freeway, I mean like a ghost town, not to mention we were far away from the city. I decided to see how far she could go. Ive had it to the 145 MPH speedo limit several times, but noticed it was still pulling very well and still had plenty of RPM left. Anyway, to make a long story short, I kept my foot in it until the engine redlined at 6k in 5th gear. I was wondering if anyone knew what this equates to in speed.

Heres the variables:

5th Gear ( Which I believe is 0.68 )
6,000 RPM's
4:10 Gears
Stock 18" Wheels and Tires ( P235/50ZR18 )

Much thanks!

 

174 using one calculator i have....

 

175.77 @ 6k RPM by 1 calculator which shows 5th on a manual as 0.675
181.66 @ 6250 PRM by another listing 0.68.

 

3 ...2....1... here come the " you should not be driving " comments.. lol

hammeron what calculator u using ? I wanted to compute something similar as well.

 

I wonder what the stock tires are rated at as far as speed.

 

I also got 174.

RPM - 6000
Rear Gear - 4.10
Trans Gear - 0.68
Tire Diameter - 27.25

 

Just think if you had 2.59 gears you'd go 275 MPH...LOL!

 

this one, save it to your pc then
rename it to have .xls file extension.

 

I hope you changed 5th gear from the 0.75

Even the auto is 0.71

 

You should NOT be driving!!! This is terrible!

I SHOULD HAVE BEEN DRIVING!

ROFL

Dude, that is truly awesome!
