aircraft guys generally only spin them up to ~3000rpm.

For reference my EG swapped impreza runs 3200rpm on the highway for hours with no problems. Stock cooling on the motor, but a griffin radiator.

Also, the aircraft guys are under less load, and they are pushing less air through the motor usually (due to altitude and whatnot). So the engines should run cooler.

Also, the crank and cam pulleys are nearly identical to the EJ equivalent.
