We have an amazing YouTube series that goes in depth about what we do, why we do it, how we do it and more. If you really want to know more, we do urge you to watch them and follow the series “Viking Talks”

Some other videos that go deeper into talking about what we do.

Why we choose OEM built, tested and proven engines over building outdated technology from decades old replacement parts.

Selling used engines has always seemed to be a controversial topic, it is time to dig a little deeper into the reasons we offer both used and new. Lets start by clarifying what used is.

We start with the most up to date year engines with super low mileage, derived from fender benders across the US. When customers want the information about where there engine core came from and how many miles it had - we have all that documentation readily available to show.

Companies like Honda and Mitsubishi have spent millions of dollars refining and testing. We don’t claim that we can outsmart either company when it comes to the design of any internal running component of these engines. We don't change vital engine parameters around and claim we have different models. The compression, etc. is all stock. Every part is OEM Honda / Mitsubishi, nothing is new aftermarket from unknown origins.

Our Business Model and Why it's Important

Viking uses the absolute latest available engine technology for their aircraft engine conversion. No 1990’s new blocks or hand assembly just exactly the technology you would expect from buying a modern showroom car.

Here at Viking, we spend every waking moment thinking about torsion dampers, radiator efficiency, power to weight ratios, and all sorts of things related to engines and flying machines, we love what we do and never think of it as work. We are in it for the love of aviation, flying and all things undiscovered. We built the first Zenith Cruzer and the first customer Zenith Super Duty. We install our engines and fly them all over the US

Why Choose Viking?

• You are getting PROVEN results, with customers who have hundreds of hours on their aircraft. Check out our forum and website and see for yourself.

• Always ready to ship - next day, no waiting 6 or more months to receive your engine and a full FWF kit.

• Viking is always available to assist you in your installations, flights and problem solving along the way. Most of all to see you fly successfully and be happy with the results.

• Viking continues to be the most affordable engine option without sacrificing quality or performance with engines at $9,995.00.

A lot of new companies will state compatibility and longevity numbers with no real flight hours and evidence that it does more than just "fit" Do your homework, talk to real customers, and be safe in your decisions. 

FAQ & More information

Internal Friction Reduction Technology
Viking engines with world class “Internal Friction Reduction” engine technology.
As a leading provider of engines to the Experimental Aircraft builder community, it is important for us to convey to our existing and future engine owners, what exactly they own, or are about to own if purchasing a Viking Aircraft Engine.

The Viking engines generally cost half the amount compared with other brands, there is sometimes a misnomer that you somehow end up with an inferior engine. Nothing could be further from the truth. The reduced cost is simply due to that the Viking engines are based on the latest mass-produced Honda car engines.

Internal Engine Friction Reduction Technology

What does the technology consist of?

The outer skirts of the Viking lightweight aluminum pistons feature a low-friction coating applied in a unique pattern. The result is reduced overall friction as the pistons move within the cylinder bores.

Plateau honing further lowers the friction level between the pistons and the cylinders by creating an ultra-smooth surface. Plateau honing is a 2-stage machining process that uses two grinding processes instead of the more conventional single honing process. This also enhances the long-term wear characteristics of the Viking engines.
Low viscosity oil (0W-20) further reduces friction.
A special 2-stage oil pump relief valve reduces friction when maximum oil pressure is not needed.
Low-friction oil seals in the engine and Viking propeller speed reduction unit.
Special low-drag piston ring design, yet high compression.
Low-friction cam chain
Each journal on the forged-steel crankshaft is micro-polished to reduce internal friction.
Lightweight crankshaft.

Viking cylinder bores are offset by 6.0 mm from the crankshaft to help reduce piston-sliding friction. This gives the connecting rods a more favorable angle during each power stroke, which reduces side loading on the pistons and, in turn, improves efficiency.

Viking engines have their exhaust manifold cast directly into the aluminum alloy cylinder head, bringing the engine up to normal operating temperature quicker, reducing internal friction and increasing engine life.

Engines have a lightweight cylinder head that is made of pressure-cast aluminum alloy. A silent chain drives dual overhead cams and four valves per cylinder for a low friction cam system.

Viking DOHC 16-valve engines uses an advanced valve-control system to combine high power output with high fuel efficiency. The system combines Electronic Variable Timing Control, which continuously adjusts the intake camshaft phase and Lift Electronic Control which changes the lift profile, further reducing valve friction during cruising operations.

Why do the Viking models have this advanced internal friction reduction technology?
There is no secret that Viking did not invent this technology. We just believe that those that linger behind with air cooling and low volume engine production, will never know the benefits of having it. We use the technology because it is already available in the engines we convert for aircraft.

What benefits does this technology have for aircraft?

Those that have not experienced the power, torque AND fuel efficiency of the Viking 130 engine will have a hard time with this one. Let me say that again: Power, torque AND efficiency, all from one engine.

You will hear things like: airplane engines operate at a constant RPM and all these modern features don’t matter.

Well, that’s where it all falls apart. Of course aircraft engines operate at different power and RPM. In fact, almost more so than in a car. In an airplane we want maximum power for takeoff, a powerful climb, a fast cruise, a maximum endurance cruise and a smooth idle.

Why is it that none of the competitor engines have this technology?

Because it is not possible to design / implement this at an affordable price unless you have made 18,000,000 cars since 1947.
