these things reach peak hp at 4800 rpm at which point the early has about 105 ft/lbs while peak torque is achieved at 2800 rpm and is about 130 ft/lbs, i believe that the engine was intended to be used in this range(redline is 5400 and normally from my limited experience there is about 500 rpm of overrev designed into most engines), i tach it to 4400 every day and it handles that perfectly fine.
Yeah... 2500 to 3500 RPMs seems to be the happy place for my 22REs and 22R..... But... always ready and willing to rev up to 5,000 RPMs without complaining.
Gnarls.
