Off-idle RPM = 2500, interesting
2000 RPM = fast idle?[/QUOTE]
My solid roller motors idle at 1200-1300, so I suppose you could consider 2000 a fast idle.
Some of these engines will not even cruise at 1800-2000 because the cams won't let them. I can't imagine trying to figure out what some of these these things do at 2500 at WOT.
