What's the speed of a typical 914 in 5th gear at 3,000 rpm ? My speedo have been under reporting for a while.

Jim,
That would depend on your wheel/ tire combination. I run 195/55/15's on mine and I am doing more engine RPM's at any given speed that if I were running 195/75/15's. I believe there is a tire size/MPH calculator on this site somewhere. How did the mirror joystick work out? Tom |
