American Rotary Engine /Auto PSRU’s
We’re combining these two very separate companies under one heading because they join to offer a Mazda 13B rotary engine conversion package. American Rotary builds the Wankel engines while Auto PSRU’s makes the propeller gearbox. Their long-standing offering is a 200-hp firewall-forward fitment for the RV-7.
We’ve already introduced Auto PSRU’s in this guide under our Inline and V Four-Stroke heading; American Rotary Engine is the aviation sidebar to Atkins Rotary, a hot-rod shop up to their necks in modifying and supporting Mazda Wankels for auto racers.
