Superior XP-Engines

Optimize the performance of your factory new XP-Engine with these popular options

No two homebuilt aircraft or helicopters are the same and neither are their engine requirements. So no matter which XP-Engine you are using to power your project, we offer an array of engine options that will help you create an engine that is the perfect match to the performance goals of your kit plane or helicopter.

Current upgrades and options for XP-Engines include roller lifters, cold air induction sumps, electronic ignition systems, and fuel injection systems.  

Superior Exclusive!

Cold Air Induction Sump

slide0007_image015.jpgOur lightweight, cold air induction sump is offered as an upgrade to the standard updraft sump. Crafted from aluminum and weighing three (3) pounds less than the standard sump, it features a unique design that separates the plenum and sump. This design improves engine performance by delivering a cold air charge directly into each individual cylinder.

The cold air induction sump also features a forward-facing design that is compatible with the majority of popular kit aircraft cowling air induction flow designs, greatly simplifying installation.

Superior’s cold air induction sump also offers design features that make it easy to install with an inverted oil system.
