This is the latest addition to our line of extreme performance products from the Hyper FIT R&D team. It utilizes the adjustable velocity stack design as applied by Yamaha. The adjustable velocity stacks enable the velocity stacks to be long for more bottom end power and torque, then lift off to enable lots of peak horsepower on top end. Our Alcohol Fuel Injection System has instantaneous throttle response, better performance, and more consistency over carburetors and other alcohol conversion systems. This system produced three more horsepower throughout the entire power band over stock injectors on gasoline using a stock engine, and more gains are achievable using a modified engine. The alcohol is also safer and cooler than gasoline.
