At the time this was the worlds only Subaru on an RV9A using a hydraulic constant speed prop. This prototype unit has all of the same features of the original Geared Drives PSRU including its own oil reservoir, oil pump and filtration system, drive port for hydraulic prop governor, and flywheel and centrifugal clutch assembly. This airplane with the P2 prototype Geared Drives PSRU can be seen at Sun n Fun Air Show, Lakeland, FL, April 21-26, 2009. Look for the Geared Drives booth N52 for directions the aircraft location.
Aero-TV: Viking Aircraft Engines - Powerful Yet Efficient Alternatives
An Alternative Sport Powerplant Shows Great Promise... And Power
At the 2011 Sebring Sport Aviation Expo, few displays got more attention than Viking Aircraft Engines. In an industry heavily dominated by one powerplant manufacturer (and one whose prices keep heading for the stratosphere), then news of what appears to be a solid alternative engine offering sure gets everyone's interest.
The latest offering form Viking Aircraft Engines Jan Eggenfellner is the Honda-based HF-100 sport aviation powerplant. The product of an experienced engine design team in Florida, the HF-110 engine shares moving parts with the Honda fit automobile, the Honda outboard marine engine and the Honda race engine. The engine has an estimated TBO of 2000 hrs, and powerplant installation kits are either available or being prepared for Jabiru Aircraft, CH-601 XL, CH-601 HD, CH-650, CH-750, CH-701, RV-12, Storch, IBIS MAGIC 700, SeaRey, Sonex, Savannah XL, and the Morgan Aeroworks Cougar.
The fully assembled engine comes with a 40A Alternator, Dual Engine controllers, Exhaust / Muffler, Air intake, K&N Filter, Starter, Radiator, Oil cooler, fuel pumps and an Engine mounting kit for your airplane. The price is $13,000. Designer jan Eggenfellner first made a name for himself with a number of Subaru conversion projects... and is a professional pilot and aircraft mechanic. He has six years of college behind him, with degrees in Aviation Management, Flight Operations and Aviation Technology. He has been building aircraft engines since 1992 and does all the test flying himself.

Glasair 1RG Fly By 260 MPH - Subaru EG33 Motor
Father-In-Law's first flight in a Glasair aircraft powered by a Subaru Alcyone SVX EG33 six cylinder 202 cubic inch engine. He had never before experienced any "G Loads" and handled them well. Watch us make a high speed missed approach.
Geared Drives PSRU for Subaru Prototype Test Run
By popular demand, Bud Warren of Geared Drives has developed a new spur gear and centrifugal clutch PSRU for Subaru! This double reduction redrive, accomodating reduction ratios up to 3:1, is exceeding all expectations in testing. This unit, like the original, has its own oil pump, oil reservior and filtration system, but best of all allows the use of a constant speed prop (or any prop you wish) since it has a drive port for your prop governor built right in. Oil temps run cool, the unit is absolutely quiet and lighter in weight than the others. The unit mounts on a plate like Eggs. As seen here it is mounted onto a 350 Chevrolet engine (Frankenstein) and original Geared Drives back cover just as a transition to the Chevy for test running only. See our website for more information.
Geared Drives 200Z PSRU for Subaru
Test running the Geared Drives PSRU for Subaru on our test engine mule, Frankenstein. Running for eight hours this day, the oil temperature is cool enough you can wrap your hand around the oil filter and it is barely over body temperature. Swinging a 72" Hartzell two blade hydraulic prop at full pitch, the gearbox is performing perfectly and ready to take its place as a retrofit to Eggenfellners gearbox. Torsional harmonics are resolved via the Geared Drives centrifugal clutch system.
Gipson's RV-10 with Geared Drives LS1 Engine Runup
Bill Gipson of Conroe, TX runs his RV-10 with the Geared Drives PSRU and LS1 Firewall Forward Package built by Bud Warren. Notice that the engine runs great at any RPM. We are expecting fuel burn rates from this combination in the range of 7-15 GPH. With torque multplication throught the Geared Drives PSRU the performance will be astounding! Be sure and notice that there is no gear noise at all heard with this redrive, just the smooth throaty sound of a Corvette engine.
