Sky Dynamics 6 cylinder Maxi-Sump System

After more than three years in the conception, design and production, our new Maxi-Sump System for the Lycoming 6 cylinder horizontally opposed aircraft engine is now available. This system is a clean-sheet design aimed at the aerobatic and air race marketplace.

The sump uses our unique swiveling oil pickup to support longer knife-edge and vertical maneuvers.  This pickup is located in a small defined sump pocket that requires less than ½ quart of oil to regain oil pressure when going from inverted to upright. The intake plenum is mounted on the bottom of the sump and utilizes oversized stainless cylinder tubes. The tubes are heat treated in our state of the art vacuum furnace. The tubes feature o-ring flanges with double o-ring seals into the plenum housing. The injector mounting face is angled up 15 degrees to facilitate smaller, tighter cowls. For pilots not requiring an aerobatic sump, this same intake system can be mounted on a stock Lycoming updraft sump. This allows the use of the larger fuel injector for maximum air flow. More details on our 6 cylinder intake system can be seen here.

The final complement to this system is our unique 6/1 exhaust system with vacuum breather system. This is the system that is used by all the top aerobatic pilots and Red Bull race planes. Like our intake system, all critical components are vacuum heat treated for dimensional stability and longevity.

At Sky Dynamics Corporation, we are proud of our 30+ year history of supplying exhaust and engine parts to the world’s best pilots. In recent years, there have been many imitators of our parts.  We take these as compliments and we will continue to innovate to provide the aerospace industry with the best parts available.
