Somewhere I read that cruising RPM should be near or below the torque peak of the engine. This produces the best engine efficiency. Most of our engines produce their best torque under 3000 rpm and probably closer to 2500. So, if Casper cruises along at 2100 to 2500 rpm that's probably ideal !! Armand Some one slap me if I'm not remembering this correctly. _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
