When I purchased my 200speedster Naturally Aspirated (310HP), I ran against a Super Charged(430HP) model identical to mine. We had exactly the same boat load, fuel and conditions running side by side. The only difference was at speeds of about 52+. The Super Charged model walked ahead...didn't run, but walked ahead of me. We played for about 45 minutes and the Super Charged model used 2x's as much fuel...at 91 octane. After we were done playing, the big comment was he wished he saved the extra money and got the 310 HP. Less maintenance too.
