I am retired and worked with reciprocating engines and compressors my entire 40 year career. Slower RPMs is always better. Your forces are increased by the square of the rotative speed. I guy in my club says if you drive an A at 35 - 40 mph they will last forever. Enjoy the ride....there is no need to drive an A over 40 mph. Why would you drive faster in a car with mechanical brakes and no protection in case of an accident? If you need to get to a destination and drive at highway speeds, take another car.
