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.
400 HP Corvette V8 Engine in a Cessna 172 - experimental
Quiet Aviation has put the convenience, power and reliability of Detroit's
best engineering into a complete package that can be installed in a variety
of experimental aircraft. Visit www.quietaviation.com to learn more about
this unique and groundbreaking aviation technology.
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
Truyeart LS1 Engine for his RV-10 Starts for the first time!
Another Geared Drives LS1 engine package for RV-10 roars to life for the
very first time! The engine starts easily and runs at low RPM since it is
not good for it to run without the load of a propeller on it. We run it
long enough to test the systems, check for leaks, test the PSRU etc. At the
very end of the video you can see the breather on the PSRU kick over the
little bit of overage of oil as it seeks its natural level in the gearbox.
This is normal for a first run up.
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.
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
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.
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
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.
Roger Followell's Geared Drives LS1 Engine for Legendary P-51
Bud Warren starts the Geared Drives the LS1 Chevrolet firewall forward
engine package with Geared Drives PSRU prior to delivery to its owner,
Roger Followell. I heard the engine start up so I grabbed my camera...this
was the very first start and it did start first time. We are running it
gently since there is no load on the engine.
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.

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.
