We offer air superiority thru research, testing and feedback from kit manufactures 

Extreme engines are: Extremely reliable/ Extremely fuel efficient/ Extremely versatile

              "Reliability is everything in planes. Performance is only considered after reliability is assured"

Electronic fuel injection has been used on the Predator UAV since 2001. The predator program now as almost 300,000 hours of flight time. What we offer is proven technology for experimental aviation use. Our fully redundant package mirrors much of the technology found on the predator UAV.

Their is nothing better than MIL Spec

Why do I Need to Fuel Inject my experimental aircraft??

     All aircraft engine manufactures would like to put fuel injection on their engines, but  due to the liability

     and the research and design of a proper fuel injection system, most  manufactures simply don’t bother.

    Are fuel injection systems unsafe on aircrafts?

     No, this is simply not true. Look at the Exec line of helicopters; they switched back in the 1990s 

     from carburetors to a redundant fuel injection system. A proper fuel injection system is many more times

     safer than any carbureted engine, and how about Continental line of fuel injection.

   Fuel injection offers more benefits than you can imagine.

• Greater HP than carbureted engines
• Best fuel economy possible
• longer time between overhauls
• Smoother and faster throttle response
• Greater reliability with a truly redundant system (Saftey)
• Alot Greater HP at altitude

    Other reasons why Extreme Fuel Injected engines is the way to go

• Now nearly plug and play
• No playing around with carbs to get them to run right
• Single throttle body
• 50 amp alternator standard
• Rev limiter, timing control, direct port fuel injection

    More Horsepower than carburated engines

      The fuel Injection Computer:

     The fuel injection computer we use to drive our engines are the sds-4F system.  The company which develops the fuel injection  

     computer has sold thousands of these units. Below is a RV6 using a sds-4F fuel injection system to power a Subaru engine.  Racetech has

     been in business for over 15 years and has proven its self for the aviation market as a reliable fuel injection computer. Their are hundereds

     of planes flying with sds fuel injection systems. Every kind of engne from VW engine, Subaru engines, Continental engines, Lycoming

     engines, and Honda engines. The fuel injection computer was developed Aircrafts.

     Fuel and timing curves are tuned on a dyno up to their maximum potential. Ignition and fuel maps are based on load, throttle  

     position and manifold pressure. A 3D representation is shown below 

   Due to the liability, aircraft engine manufactures use CDI ignition with flat ignition curves. Aircraft engines run a set 

   Degree ignition point of 26 degrees. This flat 26 degree ignition curve means slower response the throttle movement, lower fuel   

   economy at part throttle, lower HP at part throttle, and an overall derating of aircraft engines 

Is their any other reason why my engine is derated besides ignition ?

   Yes, engines with carburated are just guessing and getting your engine to run in a range. Generally, carburetors are tuned very rich

   in order for them to not "lean out" during flight. Every JP engine is tuned to 13 air fuel at partial throttle and 12.5 for full throttle  

   The Engine control system constantly updates how much fuel to inject into the engine to keep

    your rotax running at its peak performance.

Longer time between overhauls

     Yes, I can sit here right now and tell you that you will get longer time between overhauls just by using fuel injection. Why, Well its 

     simple. Engine using carburetors instead of fuel injection run much richer than a fuel injection system using an oxygen sensor.

     Running right doesn't hurt the engine in the short term, but in the long term excessive carbon from unburned fuel causes damage to

     piston rights and also damage to valve seats. Running rich will also gunk your engine up and cause deposits which rob power.

Smoother and Faster Throttle Response

     Yes, our engines do that too. It goes back to being able to advance and retard timing. JP fuel injection systems can rev up like a race

     car. Stock engine have fast throttle response when they are operating 75% to 100% power, but below this they tend to be      

     a little laggy.
