Message	I found a calc and entered the following: Final Gear Ratio: 3.692 Auto Trans 4th Gear Ratio: 0.694 Tire size of 275/35/18 @ 7000rpm I get a speed of 208mph @ 6400rpm I get 190mph Does this match your calculations? One thing I do not understand, with factory wheels, the car in the other thread *should* have been going closer to 170mph at the RPM shown for 5th gear. I don't get this stuff!
