Where an engine makes it's peak torque is dependant on how it is tuned. If it is tuned for high performance it makes it's torque high in the rev range. If it is tuned for reliability and drivability then it makes the torque much lower.
Response & Question
Brad said that his engine is tuned for an aircraft application, not automotive. He has tuned this engine to deliver torque low in teh rev range. This equates to good fuel economy.

The engine size and efficiency effects the torque. And as far as peak torque goes, the Hayabusa makes more.
Response & Question
Brad's engine has not been designed for peak torque, it is designed for economy. Therefore Revetec engine is more effecient becuase its torque is reached at an earlier RPM.

You see there is a negative to making torque low in the rev range, and that is that you need to select a taller gear to run at the same speed. And torque is effected by gear ratio's, therefore the issue gets confused.
Response & Question
How do diesel engines deal with thsi problem then? They have torque low in the rev range yet they manage to get away with it doent they. But they dont do it with an engine that weights less and is smaller in size.
Now, I am looking at this as a casual observer reading the facts and Pneumatic based on what you have said I cant really see your point?
Brad, what is your response on this?
