Oil Sump

4cyl. Lycoming Maxi-Sump Cold Air Intake System is the lightest available at a system weight of 11.2 pounds. For aerobatic engine installs, we offer the optional aerobatic oil pickup, which increases the weight to 11.9 pounds. That's 9 pounds lighter than a standard Lycoming IO-360-A1A sumpintake, while offering better engine performance and vastly superior oiling in aerobatic flight conditions. Additionally, our magnesium sump design does not sacrifice any of the structural benefits that are necessary for the engine assembly. In the early 1980's the Maxi-Sump System was introduced to the world of aerobatics. Since then, many hours of dyno testing along with thousands of hours of flight testing have been accomplished. The Maxi-Sump system has been used throughout the world at the highest levels of aerobatic and racing competition.
With the introduction of the higher horsepower Lycomings to aerobatics, there came a need for lighter components and improved oiling systems to reduce engine temperatures. In recent years, the very popular 180 hp Lycoming has been replaced with the later 200 hp (360) and 210 hp (390) versions. Competitors looking for increased performance have opted for the extra 20+ hp but have paid a weight penalty to do so, approximately 25 lbs. Much of this weight increase is due to the standard intake and oil sump assembly. Recognizing this, we developed a new cast magnesium sump with a separate intake system to replace the standard Lycoming components. This magnesium sump contributes to a weight savings of approximately 9 lbs and importantly, it does not sacrifice component strength for this weight savings. Our Maxi-Sump system is designed to be used with the Christen inverted oil system in aerobatic installations.
