In looking over the Superior web site, they have a new 220hp XP-400 engine designed around the basic IO-360 Angle Valve chassis that looks pretty nice. At $30,000 new, its $3-4k cheaper than the Lycoming IO-390 solutions and, if you believe the Superior mantra, a better designed engine in general. What is the real-world quality and reliability of Superior-built engines? Has anyone flown behind one of these new XP-400s? Has anyone Dyno'd the XP-400 to prove the 220hp claim? XP-400 Information: http://www.xp-360.com/index.asp?content=14 Avweb Article: http://www.avweb.com/news/motorhead/189629-1.html?type=pf Thanks for your insight!
