I shock heated my engines again on Sunday... This is ~ 5,800 times on the
left engine and 6,400 times on the right engine that the metal has been taken from ambient temperature (a balmy 28f degrees sunday) to some 1200-1300 degrees F internally in ~10 milliseconds... I watched with incredulous eyes as neither engine had a jug fly off, nor seized up, nor started a death rattle, nor immediately dropped compressions into the 40's... Then upon landing I reduced the throttle and watched as the EGT took some 5,000 milliseconds to to begin to decrease and the CHT's barely dropped until I was half way back to the hangar on the taxiway... I obviously shock cooled it into oblivion... denny - straight from hades... "Jay Honeck" wrote Until you can prove conclusively that shock cooling does not exist, baby the engine. That's good advice -- with any engine. --
