You might be a Motorhead if…..


You might be a Motorhead if you have a piston from a 28 cylinder Pratt & Whitney R-4360 ‘Wasp Major’ radial as a coffee table ornament in your home.  Doesn’t everyone recognize tasteful interior decorating when they see it?



Above, a R-4360 piston. Forget the 5.75″ bore, this engine had a 6″ stroke to go with it, and that piston had 27 angry siblings working with it, all fed by a combination of supercharging and turbocharging.  Each piston is 156 cubic inches of displacement, the motor is seventy-one liters. This particular piston flew at Reno in the Unlimited Sea Fury “Dreadnaught”. It was a gift from a Corvair builder who was a member of the planes pit crew.  The little piston riding piggy back is a 2,850cc Corvair piston.




About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at and in more than 50 magazine articles.

    If cool was cool, that’s COOLER than cool. Press on.

    I have seen pistons like that (OK maybe smaller) used as airport ash trays when smoking was still an allowable behavior. Not the mos functional but not prone to tipping.
