Our engine packages offer a bolt on solution for those owners of
experimental aircraft who require a modern and more cost effective
engine solution. Our engines offer 30% better fuel economy than a
six cylinder aircraft engine.
Congratulations to Frank Braun of Yucca Valley, CA for
the successful first flight of his Bearhawk with Geared Drives LS1 FWF
engine package on March 8, 2011!
New CNC machined billet aluminum case for the BW-350 PSRU for LS Series
Chevrolet
engines, adaptable to 4.3L Ford V6, BMW V12, Big block Chevrolet, and
others.
Designed
to replace Eggenfellner's Gen X PSRU and adaptable to any engine requiring a zero offset. This double reduction 200Z
PSRU has all of the features of the BW-350...to

The Geared Drives Model 200Z PSRU, AVAILABLE NOW, resolves torsional harmonics, eliminates engine kick back and offers a sound alternative for the Subaru engine owner.
PSRU for Honda V6 and possibly a FWF engine package is possibly on the horizon...in early development stage is a brand new PSRU designed specifically for Honda V6 engines. A smaller and lighter version of our BW-350 model, this PSRU will offer all of the same features. Torsional harmonics are dampened via our own centrifugal clutch, with spur gear and CNC machined billet aluminum construction, and it's own integrated custom oil pump as with the 200Z gear box for Subaru mentioned above. Stay tuned for new developments on this project.
UPDATE: Lack of availability of a reliable and consistent source of new or remanufactured V6 Honda engines has put this project on hold for now. We have even strongly considered V6 Chevrolet, but are not able to obtain all aluminum 90̊ engines (60̊ engines are too tall) We have not given up, so stay tuned.
