Can I put a Rotapower Engine in my car?
The current model is not intended for use in automotive applications. 3.5. The page listing Rotapower Engine Performance Advantages states “power output/weight greater than 2 HP/lb.,” yet the gasoline engine comparison lists the 150 HP Rotapower engine with a weight of 135 lbs. Why? We have achieved 2.5 HP/lb. in the lab with our special high performance model. The 150 HP version is a de-rated marine engine. This number is close to that for a production engine — in an application for long life.
