Cleanex
Cleanex = Sonex/Waiex/Xenos with a Corvair Auto Conversion Engine Installation
Cleanex History – Dan Weseman built a Sonex airframe (firewall back) powered by a 3100 CC Big Boy Corvair engine, encased in a custom cowling. Dan named this feral beast “The Cleanex“, N183SX. The Cleanex first flight was on September 11th, 2005. Please find more information about the Cleanex below. Even though Dan sold his Cleanex, N183SX the summer of 2010, we offer Cleanex nose bowl, engine mounts, intakes, engine cooling baffle kits and (of course) the 5thBearing.
The goal was to find a reasonable performance alternative to the relatively expensive Jabiru 3330 engine endorsed by Sonex. While we believe the 3300 is a fine powerplant, a 15k or higher hit for an engine, compared with the investment of approximately 5k in the airframe, seemed out of proportion.
The AREO-VEE 2180 is a great engine, and is a perfect choice for the budget minded builder. However – we really wanted more power, and liked the Corvair engine for many reasons.
The FWF costs with the 3100 CC Big Boy Corvair engine was about $7,000. We spared no expense in the construction of the engine, including the increase to 3100cc, William Wynne’s oil pan, ignition, and front starter, using a certified ma3-spa carb, Fly5thBearing.com 5th Bearing,etc.
The FWF weight is estimated to be about 220 pounds, similiar to a Jabiru 3300 powered tri-gear Sonex. Power at 3200 RPM is expected to be at least 110 HP. Total aircraft performance has met that of the Sonex with the 3300 Jabiru.
