I get plenty of flak from "experts" who doubt my rpm readings on given engine setups - because I run the engines at 4500 ft elevation.
The claim is that I get higher readings because the air is thinner - plus -the use of a tuned exhaust is of greater advantage at higher altitude.
Frankly, I think my readings would be about the same -if I hauled the whole test setup to sea level.
Further - I think my readings would increase.
Maybe I should stick to easier questions ---
If you ever do haul the test rig to sea level, please share the results...
