'Shock cooling' more folk lore!!!!!!!!!!!!!
Chit, now I have to go and use black out on all my P&W and Wright radial engine manuals.....
Especially my manual for the C117 because there are many " Warning " notices in that outlining the danger of cylinder choking due to shock cooling.....
....we could get into reverse bearing load caused by high RPM and low manifold pressure but I won't go there now.
If shock cooling is a factor in engine life in big radial engines can someone explain why the laws of physics should be different for other air cooled piston engines?
