The Aerotek engine below was converted from a Subaru automobile engine and was built by Aerotek Performance Products of Lethbridge, Alberta, Canada. Aerotek developed the adaptation for builders of homebuilt, experimental aircraft requiring a 40-60hp engine. The approach taken by Aerotek was similar to what many developers have done with VW engines and some with Corvair engines; i.e., modified a four- or six-cylinder HOAE into one with two (or three) cylinders. Most Subaru conversions require reduction of propeller rpm from that of engine rpm; i.e., a Propeller Speed Reduction Unit (PSRU). The Aerotek PSRU incorporates a belt drive of the firm's own design. The information here has been compiled from the Ultralight News Report from Sun'n'Fun 1998. and from SA9/98. All of these engines are non-certificated engines for use in experimental, homebuilt aircraft.
