The company is using Honda L15-series and Mitsubishi car engines for their conversion to an aircraft application. You may buy them new from Honda but most customers opt for used engines that have been used in cars for less than six months or 5000 miles. After they leave the Viking factory assembly line they can be considered as a rebuilt/new aircraft engine.
The result of this hard work is an engine with the latest technology for the lowest price available. The fuel economy is world class; the power to weight ratio is superb. The quality of the engines is as good as Honda gets it and to ensure reliability, Viking performs dynometer testing combined with thousands of hours of in flight testing.
Honda / Mitsubishi is manufacturing these engines in thousands per year (unlike other aircraft engine manufacturers) with enough parts readily available and, more importantly: for a reasonable price. This guarantees the customer benefits from the absolute latest in engine technology for the best price.
The Viking 130 is as close to a Honda Fit (called Jazz in some parts of the world) car engine as possible, retaining all of its modern features. The cooling system is filled with Evans liquid cooling under a very low pressure system and the engines are usually run at 66% of the maximum rated RPM as designed by Honda.
One of the main advantages of this engine is its low weight to power ratio compared to other engines in the market today. The fuel injection system is a GDI, gasoline direct injection. This is much like the system used in a diesel engine where fuel is injected directly into the combustion chamber. Normal gasoline fuel injection systems inject fuel just before the intake port, Rotax iS and ULPower are a good example of engines using this principle.
For those of you flying with the Viking 110 (see image above) we have the engine installation manual available.
The company Zenith Super Duty is faster than any other flying at 126 kts / 154 mph TAS @ 8500 ft DA. It also has the shortest takeoff roll of any CruZer. In fact, the airplane is so powerful; it can takeoff much shorter than a full fledged CH-750 STOL airplane.
Listed below are some of the advantages of a Viking aircraft engine:
All of this results in an unbelievably smooth running engine, your passengers, airframe and avionics will love you for that!
Viking engines are used and flown in a large number of aircraft ranging from Just Aircraft, Cessna, Rans, Vans RV-12 to the Zenith Aircraft CH650 and CruZer to name but a few.
Viking will help you install your engine at your location! This is a service which is rather unheard of in the experimental aircraft community. This shows the commitment the company has toward its customers: its not about crating and shipping an engine as quickly as possible, but full support to get you flying with it!
The latest addition to the range of engines by Viking is the V90 built with a Mitsubishi 1.2 liter, fuel port injected (not direct), three cylinder 90 hp model with a variable camshaft for the intake valves. Electrical power generation is done with a genuine Nippon-Denso 40 amp alternator. This V90 is a less expensive alternative to the Rotax 912 series engine and built with modern technology. See image to the right.
There are four derivatives of Viking engines at the moment. Below an overview with the specifications, for current pricing and availability we refer you to the Viking company website.
|Engine Model||Drive Type||Horsepower||Weight|
|V90 (1.2 L - 3 cyl.)||Geared||90 hp / 67 kW||159 lbs / 72 kg|
|V90T (1.2 L - 3 cyl. Turbo)||Geared||100 hp / 75 kW||164 lbs / 75 kg|
|V130 (1.5 L)||Geared||130 hp / 97 kW||220 lbs / 100 kg|
|V150 (1.8 L)||Geared||150 hp / 112 kW||~225 lbs / 103 kg|
|V195T (2.0 L Turbo, Accord)||Geared||195 hp / 145 kW||~290 lbs / 131 kg|
All engines can run on 100LL AVgas or Mogas, use 0W20 viscosity lubricating oil, Mobile One 75W90 Synthetic gear oil, and the coolant is from Evans NPG Plus (waterless) under 4 psi of pressure.
Comparing the Viking 90 with its competitors Rotax 912 (80 hp) and the 912iS (100 hp) we see a huge advantage with the Viking 90 engine power and torque wise, see this power/ torque graph.
For a power/ torque comparison of a Viking 130 to an ULPower UL350iS, see this image of the V130 power curve.
The initial Viking turbo engine was based on the 1.5 Liter Gasoline Direct Injection Civic engine capable of 174 hp. To get an idea of the technologies used in this Honda engine, have a look at the next video: Honda Turbo 1.5 L engine animation. As of 2018, Viking also uses the 2.0 Turbo Honda Accord engine with a power output of 190+ hp.
2019 saw the introduction of a turbo charger on the Viking 90, increasing its power to 100 hp. Turbo boost is a mere 2 lbs thus an intercooler is not needed. Click the next link to see a running Viking 90 Turbo engine.
Jan 2021: Introduction of the Viking 150 engine based on the Honda HRV with 150 bhp, takeoff at 5800 RPM and cruise at 5000 RPM, port injected (no GDI, just a little less efficient) and only a slight weight increase of about 5 lbs. Also, this is a brand new no mileage engine. Viking expects to have the first engine flying in February.
Especially developed for the experimental aircraft market, Viking has a range of fuel system components available like header tanks, filters and pumps to suit the Viking, Rotax and ULpower fuel injected engines. The electrical system is simplicity itself, click here for the latest electrical diagram.
