Can someone compute the rpm's for me for the stock 3.31 gears with the stock 17" wheels? I would like to get the rpm's at:
1) 50
2) 60
3) 70
4) 80 mph

I'll be ****ed if my speedo is not reading way too high and I'm just trying to do a quick check based on rpm on what it should be reading. Next step would be timing it at 1 mile, gps, etc.. but thought this would be a simple check.

 

Here you go... file in the tire size and gear ratio: http://www.2005stang.com/gallery/alb...M_vs_Speed.xls
