Phoenix Power Products Cylinders on a Lycoming IO-540

Are you looking to rebuild a Lycoming, and you’re hungry for power? Pause here and take a look at what Phoenix Power Products of Menomonee Falls, Wisconsin, has brought to AirVenture. The company has created a cylinder just for Experimentals that encompasses several critical changes, including a new combustion chamber with a “squish” area, which is essentially a very small pocket where compressed air in the cylinder is accelerated briefly, promoting complete combustion and lessening the chances for detonation. Coincidentally the squish area also serves to reduce fuel consumption and improve power output.

According to the company, the new cylinder sports a modified port design in a D shape that eliminates port swirl in the intake runner. The intake valve is an Inconel alloy, while the seat and guide are Beryllium free copper alloy. The exhaust valve is a Nimonic 90 alloy. The barrel of the cylinder is an AMS-6382 forging hardened, and the head fits standard rocker arms and shafts. Pistons and rings are included and you can order the complete assembly in a range of compression ratios including 10:1, 9:1 or a custom one.

Barrett Precision Engines is working with the company to produce a 330 horsepower version of the narrow deck Lycoming IO-540 sporting these cylinders and Barrett’s cold air intake technology.
