Auto PSRU's LLC
Auto PSRU's offers builders of experimental aircraft lower cost automotive engine alternatives to expensive certified aircraft engines.
My company manufactures two Propeller Speed Reduction Units (PSRU) gear boxes that converts Chevrolet and Subaru engines for use in home built experimental aircraft. This approach for an aircraft engine not only saves the builder a lot of money but it also puts engines into aircraft that are already running on lead free fuels. My PSRU's fit engines from 100 HP to 400 HP to fit almost every kit plane on the market.
