So much of what is discussed here has so little to do with how many of us actually use our engines. I'd like to see data for building strong every day work horses that pull from a dead stop to highway speed( 70-75) never going over 4000 rpm and crusing between 2,000 and 2,500. These are actually wide RPM ranges and could be held closer with gearing. My interests are more about drivers than racers.
