What Makes Hyper Racing's Conversion Unique?

  • The only company to offer a flat filter design, a new exciting concept that will eventually become the norm. Go to our flat filter injection page to check it out.
  • Flowed and matched nozzles insure the exact fuel amount delivered to each cylinder thanks to our in-house nozzle flow bench.
  • Stainless steel screens are used in every nozzle, to prevent blown engines caused by a stuck or restricted nozzle.
  • The under appreciated RAM airbox design adds more power on the track (not on the dyno). Forced air simulates turbo charging.
  • In-house eddy current dyno enables full testing and optimum performance engineering.
  • Professional product support provided by the expert Hyper FIT Team is just a phone call away.
  • Power Commander V tuning can be tuned anywhere, by anyone.
  • AutoTune is available. This product will tune the engine automatically on the track, while you race, in real time.

In late 2002, Hyper Racing began researching electronic fuel injection. The goal? A system that was low maintenance, offered immediate throttle response, better performance, and more consistency over carburetors and other alcohol conversion systems. After months of engineering, tooling, machining and extensive dyno testing, the alcohol fuel injection conversion for the 600cc motorcycle engine hit the racing scene.

We use the best nozzles on the market. They are positioned for the proper spray angle and to deliver the proper spray pattern for methanol fuel atomization. Although all nozzles are rated at a certain flow rate (lb/hr), each one varies slightly from the specification of the manufacturer. Our Bosh nozzles offer the best repeatability from nozzle to nozzle than other manufacturers. When the flow rate varies between nozzles, one cylinder will run richer or leaner than another cylinder decreasing performance. In all of our systems we match the flow rate of each nozzle on the in-house nozzle flow bench to maximize horsepower.

Hyper Racing's Micro/Mini Sprint Alcohol Fuel Injection System produced 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. Not to mention it smells better. The conversion involves taking your stock throttle bodies, and converting them to use methanol alcohol. Injector nozzles, connectors, and stanchions are replaced, and a custom machined fuel rail of our design with a large plenum chamber and dual feeds is incorporated. The custom fuel rail keeps the pressure constant to each nozzle and prevents pulses from affecting the supply. This alleviates problems found using the stock fuel rail on methanol. All pieces are anodized! No need to flush our system out after each race. The Power Commander (sold separately) enables the fuel map to be dialed in precisely. With adjustments available every 250 rpm’s and every 0%, 2%, 5%, 10%, 15%, 20%, 40%, 60%, 80%, and 100% throttle opening, this system can be adjusted for anything. Whether you buy the Power Commander from us or not, if we convert your injectors, you get our standard fuel map at no charge. We can also dyno your engine to develop a custom fuel map for maximum power and throttle response with our in house dyno.

Hyper FIT vs. Carburetors
The Hyper FIT Alcohol Fuel Injection System has instantaneous throttle response, better performance, and more consistency over carburetors. With electronic fuel injection the amount of fuel that goes into the engine across all rpms and all throttle positions can be precisely controlled. With carburetors only the main jet can be changed to control the fuel at full throttle across the entire rpm range. Similarly, carburetors only have the jet needle to control the amount of fuel that enters the engine at part throttle. The needle does not know the rpms of the engine or the engines need for fuel and compromises must be made. This means a sacrifice must be made at one rpm range to maximize power and response at another. Not only will peak horsepower be higher with electronic fuel injection, power at all other rpms will be better. With fuel injection, there is no need to compromise...you can have it all!

Hyper FIT vs. Gasoline
The Hyper FIT System produced at least six 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 methanol fuel is also safer and allows the engine to run cooler than gasoline.

Stainless Steel Injector Screens fit almost every injector made. Injectors come with plastic screens designed for gasoline. When used with alcohol, the plastic screen swells, restricting flow. Eliminate the potential for poor performance and damage by replacing your plastic screens with stainless steel screens.
