Boy, that's a lot nicer than the AJ Savage Lycoming (now part of Honeywell) used when I worked at Lycoming Stratford. The test engineer who was responsible for the ALF-502 flight tests on the AJ told me stories of the Lycoming's flight test manager adding TEL to gasoline to get the 100/130 up to 115/145. Last I knew, the AJ was donated to a museum.
