Behind the Firewall Engine Package for Velocity

Geared Drives completed a complete engine package for the first pusher customer, Erik Franks, in California and we are anxiously awaiting reports from Erik on the installation and his first flight! He has graciously allowed us to mention his name and to post photos of his engine package on our site.

Please feel free to email or call if you have any questions regarding the Auto PSRU's engine packages for your pusher application. The photos below are of Eriks airplane as he had just finished mounting the engine to the firewall.

The photos below were taken as it was being prepared to be removed from the engine stand used for shipping, which is why the coolant overflow tank is taped to the engine mount.


All aluminum water cooled Chevrolet LS3 engine with altitude compensating electronic fuel injection. Spur gear propeller speed reduction unit with fully automatic centrifugal clutch and flywheel assembly. Ships already assembled and test run for bolt on application to Foxtrot firewall. Custom programmed ECM and wiring harness. You add your own propeller governor, propeller, fuel pumps, and fuel regulator/filter.

NEW! We have developed a new dry sump system for the LS3 engine that allows the use of a larger radiator for more engine cooling capacity.
