R-2800 Engine Starting and Running on 100SF

On September 27th and 28th, 2011, engine tests were conducted on Swift’s 100SF aviation gasoline by Anderson Aeromotive in Grangeville, Idaho, in a Pratt & Whitney R2800 Double Wasp radial engine.  This video shows one of the starts and short runs on 100SF.

Initial test results show that 100SF was able to provide full power to the engine, which was only previously attainable by using the original 115/145 purple avgas.
