Expensive and useless, 3,000 RPM at 60 MPH ( that would be an estimate ) it would be like driving in 4 th gear in a 5 speed or 3rd in an automatic. It would be ballsy, I will tell you that. I had 4:11 in a stick shift car once . I can't imagine 4:44. I know guys that ran 4:56 in their cars. Top end was like 95 MPH . What is the point. Can't imagine what the MPG would be
