I just read the nitrous article in the new ***boat. Did anyone catch the paragraph that said to match your impeller to the engines hp with the nitrous. It stated that nitrous would require on cut larger impeller. Im not understanding that. It has always been my understanding that you want to cut your impeller to allow the engine to run at its peak hp. If this is done right, when you add nitrous it will just allow the engine to spin it even faster. Why would you want to go to a larger impeller?
