If you have a manual transmission (US model):
First gear has a 3.483 ratio.
The final drive is a 4.10 ratio
Stock tires are 225/50/16, so the circumference is 78.05 inches
Redline is 8,000 RPM
Sooooo. 8,000 RPM / 3.483 / 4.10 X 78.05 in. = 43724.6 in./min.
There are 63360 inches in 1 mile and 60 min per hour, soooo.
43724.6 / 63360 X 60 = 41.4 miles per hour.
If you have an automatic transmission, a different redline, or tire sizes different than stock, this will change.
HTH.

it ain't polite to dis DK, dude ( did i spell that correctly ) people have to begin someplace, whether it's riding on the bench, the road, the track, or yo mama

about 40mph in a stock 5 speed:

you can go about 72mph in 2nd which is perfect for auto-x

Judging by his screen name
All I can say is ......if you don't have the stock computer (rev limiter)
then why not just put it in 1st gear and run it on up the ole speedo till it won't go any higher and remember that number and grab another gear and keep on going till you find out the limits on all the gears. I'd sure like to know myself....just don't want to waste my motor to find out.

see how much she'll take before she goes pop, then repeat in every gear until you have a nice chart of max engine RPM per gear, just what every FD owner wants.... Do it for us man
