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.

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.





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.





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.

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.

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.

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.
