Message	"First trick: calculate the driveshaft rpm at 60mph. Easy. I used my 235/45-17 tires, computed the circumference and used the axle ratio of 3.69 (NA). Driveshaft rpm work out to 216." Assuming you are in 4th gear the calculation is simple. Since in 4th gear the tranny is in a 1:1 ratio with the engine all you have to do is look at the rpm @60 mph in 4th gear (about 3000 rpm) . So your driveshaft is rotating at the same exact rpm. Dunno how you got 216 :) Harry " If it dosn't make it faster, i don't care "
