Correction on first 20 minutes. It is NOT at a constant rpm. The RPM should be constantly varied to prevent any abnormal wear patterns and to insure everything is lubed properly. The first 20 minutes breaks in the cam and in a properly machined engine a lot of the rings. The first wot finishes it off. On a race engine this is usually done on the dyno so when it goes into the car its GO time.
