No, you won't feel 5 HP in a 130 HP sled, its less than 4% increase. He is better to go to NOS, it will still cost him $10/ride but he could use a 30 shot and get a greater effect. Besides, NOS is easy to use at a single moment in time, but race fuel and detonation will plague the motor at all times and you have to be so much more careful all the time with it (what elevation you are running, what blend of fuel to use, etc). With regular compression you can start at sea level and ride to elevation, then hit the button and climb the same hill as you can with the high comp motor in most cases. Higher compression on a stock motor will likely be the death of it. Snorider, in order to get more jam you will have to big bore, or just enjoy what you have. Higher comp generally works only on motors designed for it, which are the big bores. But you could big bore that motor probably and have it still be rock solid. you'll have to ask around and see what some others have done.
