Hi Lynn,
I didn't realize that you kept revs above 8000 rpm for an entire race (and thus an entire season). Is this why you tell us that an engine with 9.4 rotors will hold 7400 rpm practically forever and that 7400 rpm just isn't that high for a rotary? (proven on the track under racing conditions!!!) You have been telling me this for 4 years and I still have a little trouble believing that these engines rev so effortlessly. This is sorta (Arkie word) hard to comprehend because I KNOW what will happen to my Mustang motor if it were to see 7400 rpm. It's humorous that even after learning about the forces involved and the capabilities of the rotary how hard it is to not let your thinking be constrained by the limitations of an unrelated engine type (auto and aircraft).
