Cons: Purchase price (4000-4400)

Required battery voltage to operate. On a typical18Ah battery the engine will continue to run 30-60minutes after the ECU failing.

Recomended to be used on Odyssey batteries andnot Li-Po, Li-Fe as the lithium batteris shut down ata higher voltage than lead batteries

Installation time, typically 4-10 days depending onthe amount of hours put down each day

Pros: Pressurized fuel system (35-45psi) No risk of vapor

lock (Fuel return system)

Eliminate risk of carb icing

No need for carburetor maintenance andsyncronization

Optimized combustion

Automatic lean system (altitude/temperature etc)

Reduce consumption by 10-20%

Less vibrations due to only one throttle body

Typically 1-3Kg weight savings (depends on kit andinstallation)

Manual mixture option (+/- 50% lean/rich)

ECU will continue to run even with failing sensors asa redundancy feature.

Unlimitid TBOCan be moved over to new engine.Replace pumps every 5 years, 300

During 2000Hrs you can save ~ 18.000 on MOGASwhen decreasing fuel consumtion from 18l/hr to13l/hr. Another 2500-3000 on carburetormaintenance parts during 2000hrs.

Fuel injection is a old and proven

technology throgh the automitive

industry and not through

motorcycles, boat engines and

aircraft engines. Its technology that

will outperform carburetors in everypossible aspect.

How to convert to EFI First of all you must concider what

disposable space you have available in you

engine compartment

Simply remove old parts and install new

parts according to the installation manual

Test run the engine on groun and monitor

EGT temperatures and preferably with a

wideband O2 gauge as well

Make corrections and adjustments if

needed in the ECU controller by pressing

+/- in the RPM/FUEL menu

Turbo conversion of engines is not

something new. It was first done in 1885

Some history: Allready in 1885 Gottlieb Daimler patented a newtechnique which included using a gear driven airpump which boosted a piston

engine.

The more known turbo chager as we know it today was first invented by the

Swiss man called Alfred Bchiin 1905 who then patented the first exhaust gasdriven turbo charger. Turbo charging an engine will not only increase power

and torque but on aircrafts also maintain or boost power at higher altitudes.

Our standard system typically delivers 32 MAP in FL100 and 28 in FL145.

The way a turbo works Internal wastegate Eksternal wastegate

How the various turbo chargers work

A turbo charger contains a turbine wheel and a compressor wheel. The hot

exhaust gas drives the turbine which is attached to a turbins shaft which

drives a compressor wheel on the cold-end. The compressor wheelcompresses air and forces it into the engine make a greater combustion

explotion, which again produces more power. Simple, yet efficent technology.


16/19

VVTVariable Vane Technology is a relativly new technology which based on our experience is the

best option available for aircraft engines. It has several airfoils places in a circle around the exhaust

turbine which changes the angle of attach which again controlls the speed of the exhaust gas over the

turbine and then again the boost level. It is also self-contained with life-time turbine oil which

lubricates and cools the turbo. Thereby it does not required oil from the engine. Weight, only 4,5Kg

Principal and how a VVT turbo works


17/19

Pros Cons

1. Normalized MAP pressure and even

increased power from sealevel and

up.

2. Reduced take-off distance.3. Drastically increased rate of climb.

4. Increased cruising speed.

5. Enables high altitude flighs.

6. In conjunction with carburetors it

eliminates the risk of carburetor icing

due to the pre-heated intake air.

1. Increased weight, typically 4.5-6Kg

2. Increased fuel consumption as you

increase power.

3. Requires some space under thecowling. Fabrication of exhaust and

muffler requires some work.

4. Slightly increased temperature under

the cowling.

Big Bore KitsWe deliver Big Bore Kits machined from high dencity billett aluminum. They come in 1403cc 8.5:1 turbo.

1484cc 11:1. 1603cc 11:1. 1693cc 11:1. They are billit and not casted which gives higher material

dencity. They have 14 cooling fins over stock 9 fins and they are plated with Nikasil, Silicone and Carbid.

Pistons are forged light weight JE race pistons all balanced to +/- 0.5 grams
