Sport Performance Aviation LLC's Corvair 3.3L Stroker Engine Is Here!
Sport Performance Aviation LLC (SPA) announces their long anticipated Corvair 3.3L Stroker engine. The testing on this configuration has taken a milestone turn with the first engine run on 7/14/2015.
This engine configuration uses a stroked version of SPA’s custom USA made billet crankshaft installed in a machine clearanced case, pistons and connecting rods. This engine configuration also uses SPA’s 2nd Generation 5th Bearing, reconditioned cylinder heads and rear alternator combined with FlyCorvair’s conversion parts.
The 3.0L Corvair configuration, developed by Dan Weseman of SPA, is a 3000cc (190 cubic inches). This configuration is a popular power plant for aircraft such as the Sonex, Zenith and most recently SPA’s Panther. The stroker engine is 3300cc (200 cubic inches). The thrust of this configuration is to have a similar output of the 3.0L, but with a lower RPM to make more efficient use of propellers.
The unveiling of the 3.3L Corvair Stroker engine will commence on July 20th 2015 to coincide with opening day of EAA Airventure, in the North Aircraft Display area - SPA’s booth N615. An interest list signup will be available in the booth.
After EAA Airventure the Stroker engine testing will continue on a test stand and then move to a 3rd party Dynamometer for output verification. SPA expects to then re-engine their prototype Panther N515XP with this engine for flight testing. Based on testing orders will be accepted in Fall of 2015.  [ home ]
