We offer no BS Just the Facts

We offer Overhauled engines and offer the only Fuel Injection Kits

We also do Custom CNC Fabrication and We can Fuel Inject any Engine

    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.

    Aren't 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. How about Continental line of fuel injection.

   Fuel injection offers more benefits than you can imagine.

• Greater HP than carburated engines average of 25%
• Best fuel economy possible with your set up period up to 50%
• 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 JP Fuel Injected engines is the way to go

• Bolts on within an hour
• No playing around with carbs to get them to run right
• Single throttle body or dual throttle body set up
• 50 amp alternator standard rotax's 1200$ option
• 4 point modular powder coated engine mounts

    More Horsepower than carburated engines

      The fuel Injection Computer:

     The fuel injection computer we use to drive our military 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 Map                                                                                     ignition Map   

     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 14.0 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.

Best fuel economy possible period!

     Yes all JP fuel injected motors are guaranteed to have the highest fuel economy possible safely. JP fuel injected rotax's use 

     wideband oxygen sensor for feedback under partial throttle. The engine control unit (ECU) constantly adjusts how much fuel to put in

     the engine in order to maintain a 14.0 air fuel ratio. This is the same way auto manufacturers like Honda get much more per a  

     gallon

     of fuel. This is one reason why we can boast at JP associates that we can get up to 50% more fuel economy from you same engine.

     Why, because it is 100% true and can be shown on a dyno. Typically you are not going to gain 50% in fuel economy unless your set

     up is turned extremely rich, but 20-30% is typical

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.

Greater reliability with a truly redundant system (Saftey)

     Stock  engines are not redundant. Only JP Associates offer a fully redundant system. Stock engines are not

     redundant.  In fact, no other manufacture is fully redundant. They are only redundant in their ignition set up, but what happens if a

     problem arises with the carburetors? Yes, you do have two of them, but they are driving separate cylinders. The answer is your

     engine still fails and you fall out of the sky. When you buy a redundant system from JP Associates, you buy 2 of every fuel and

     ignition component. If you have a problem with either fuel delivery or ignition, simply switch over to the secondary computer. Buyer

     also  can plumb their secondary system into a small full cell and gel cell for added security to guarantee you get on the ground

     safely.  No matter if your fuel and battery fails on your primary computer and your run out of gas, You can be assured you can get

      on the ground safely.
