Rob Rob, turn the boost up and you can make a lot more than 600 hp with 495 ci. I have a two liter (122 ci) engine in my shop that makes 1000 hp. Durability does not necessarily go hand in hand with boost pressures involved with this kind of power output. Another factor in making more power for a given engine size is rpm. The Orenda engine is running at 4400 rpm and thus requires a gearbox. However, move the max power rpm up and generally the max power goes up. In my opinion, this engine wants to compete with the turbo props. Craig Berland
