I'd like to see real-world tests run at no more than 4000 rpms or so.
Why? Why not run the engine up to where the engine makes it's rated power? People really need to get over their fright of high RPM's. If they don't like high RPM then the only alternative is a supercharged engine where it gets it's air in early or a diesel engine.
The problem with modern computer control engines is they can pull power out at any time they want.
These high power hot rod engines have a very low duty cycle. Sure, they make big HP but then they will pull power to keep from melting down.
