At WaterThunder Performance we have been continuously
testing and improving our Fuel injection systems! In years past we stayed away from
electronic fuel injection because to be honest 90% of the aftermarket stuff was
junk! Stand alone EFI.’S were not very robust or reliable with limited tuning ability!
After working hand and hand with a leading EFI manufacture together we have developed
a very robust, reliable and extremely user friendly system. The belief fuel injection
is not reliable as a carburetor in today’s world is urban legend! Those who have
owned carbureted vehicles, know very few if any carburetors ever make it to 100,000
miles with out needing a major carburetor rebuild.
In today’s world it is demanded
and expected for fuel injection motors to run 150,000 to 200,000 miles with out
any problems. This is why all our major EFI components are OEM manufactured products.
Parts like fuel injectors, fuel rails, O2 sensors and fuel pumps. Honestly who has
more money then G.M or Ford to test and develop EFI parts at competitive prices.
The aftermarket industry has a fraction of the R&D budget General Motors has! At
WaterThunder Performance we tested our fuel injection system over and over in the
field, on the dyno and on our own test boat! We offer three levels of Fuel Injected.
motors starting from 500HP to 550HP and even 600HP! Nothing else has throttle response
and low end torque like a fuel injected motor! There are five very distinct advantages
to fuel injection, throttle response, low end torque, fuel economy, no engine run
on and adjustability to a specific RPM or load!
When WaterThunder Performance begun testing electronic fuel injection on our personal
boats. We realized the complete lack of service and technical support offered by most
manufactures and their vendors, neither offered any tech support after the sale. Any
problems encountered would only be resolved by us in house. Any upgrades or changes
took months if they even happened at all. At one point I had a manufacture asking me
how to resolve their various crank input signal problems. This was unacceptable from
a business stand point so we teamed up with a leading EFI programer and manufacture
and worked with them to Taylor fit their system to our needs. After months of testing
on several different type of airboats we started offering these 100% complete EFI systems.
The result is a 100% true turn key Fuel injection motor with no tuning or adjusting need
by the consumer. I’m an old school carburetor guy so I had to learn it all myself, so
we utilized a relay box and numbered all connections and if that wasn’t simple enough
we also supply a full description of all connections and components with pictures. A
leading airboat manufacture installed one of our 550HP fuel injected motors in one of
their boats and because of the easy to follow instructions and everything being test run,
tunned and clearly labeled they never needed to call us for any technical assistance.
That truly is 100% turn key! We truly offer 100% tech support but it is rarely needed!
We also offer any upgrades or improved tune up’s at no extra cost! Unlike some vendors
who charge $300 an hour to just open their lap tops.
Another advantage with a WaterThunder
Performance F.I. motor is our ability to meet your changing needs! If you modify
your combination or change gear ratios, hulls or even a prop. Chances are we have
tested and tunned for it already so we can adjust your fuel system and ignition
curve to accommodate your needs. Another feature we offer is a second program or
(map) enabling you to run low octane fuel or fulfill other special needs. This need
became apparent a few day’s after Katrina. When 93 octane fuel became hard if not
impossible to find! After this catastrophe we developed and installed bad gas provisions
for various government agency’s enabling them to run rescue boats on low octane
fuel. This second map can be programed for a multitude of uses such as frogging,
towing, low octane fuel or even Ethanol. If throttle response, torque and tune ability
is something you demand look into one of our WaterThunder Performance fuel injected
motors!
