Geared Drives 200Z PSRU For Subaru

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.

Michael OBrien doing a full power run on his Eggenfellner E6 engine at KDWA for propeller trim balancing prior to 1st flight... Subaru based 6 cylinder engine is turning a Quinti/Sensenich 4 blade hollow composite c/speed electric prop.. This sube engine runs so smooth its unreal!





Eggenfellner Subaru First Start
First start of my Eggenfellner Subaru E-6 engine. This is a converted automobile engine for aircraft use and is capable of producing 200 hp. Instead of burning just expensive aviation fuel, I will be able to use the cheaper 92 Octane auto fuel, or as necessary, aviation gas. Repairs and maintenance of this engine will also be cheaper then a typical aircraft engine. Being water cooled, it will have far less vibration and will be quieter then the typical air cooled aircraft engine. It will eventually be attached to my RV-8A that I am currently building.





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.





RV 10 Run up with Geared Drives FWF engine package
Note: battery was a little low...Bill Gipson of Conroe, TX runs his engine up, cycles the prop, and shuts it down for viewers. This was immediately after taxiing around the airport and filling up with fuel. This airplane runs cool, even on taxi. Note that the centrifugal clutch starts the prop just after the engine starts and also that the prop spins to a stop upon engine shutdown.

Geared Drives-starting a Chevrolet Powered Airplane from Sun n Fun
Demonstration of how easy it is to start a Chevy powered airplane-centrifugal clutch does not engage prop fully until you rev the engine up enough to taxi so no danger of it going anywhere. (Tinted glass keeps you from seeing the helper on the brakes in right seat.)





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.





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.

Franks Bearhawk Engine Test Run
LS1 firewall forward engine package with Geared Drives spur gear PSRU built for Frank's Bearhawk airframe. Test run after 5 minutes at idle produced 145 degrees, 15 minutes 150 degrees, 20 minutes 160 degrees. When brought up to 2000 RPM the engine cooled back down to 155 degrees! We have the right cooling combination and we can make auto engines run as cool as you would like in this configuration.





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. Copyright 2011, Aero-News Network, Inc., ALL Rights Reserved.

Larry Ketterlings P-51 Engine
Geared Drives FWF engine package for P-51 at idle and run up very conservatively since we were testing ignition only and there was no prop installed. Note how smoothly the engine transitions from low RPM to higher RPM. Nice rumbling sound through the short custom Exhaust, volume increased via the collector with baffling within to provide back pressure and guard against shock cooling the valves.
