UL muscle power. Weighing in at 220lbs installed, the 6 cylinder, all fadec, 160hp monster is here...The UL390IS. After unpacking and remembering to take deep breathes while moving in on the engine lift, I was blown away at the workmanship by ULPower. Not to mention it fits in the same footprint as an o-235 and is actually Narrower than an o-320 by 4 inches! The exhaust is sadly not going to work, however, and I am currently researching companies or people who have the skills to weld up a real nice exhaust for me. VERY excited because the DYNO sheet read 162hp right out of the box which means it's only going to get stronger :) More soon.
