Parker_Woodruff Posted May 4, 2009 Report Posted May 4, 2009 For those of you who are thinking about the IO-390, I had never heard of this mod for an extra 15hp. Any pireps? What's involved? "Horsepower Plus STC". 215 HP IO-360-A3B6D Quote
KSMooniac Posted May 4, 2009 Report Posted May 4, 2009 There has been some discussion on it already here...you might try searching up the threads. I wouldn't do it to my plane FWIW. Quote
Parker_Woodruff Posted May 4, 2009 Author Report Posted May 4, 2009 Yeah that doesn't sound too exciting to me. Quote
dlthig Posted May 4, 2009 Report Posted May 4, 2009 Parker, You may be talking about two different things. The Lycoming IO-390 is a factory engine that they are proposing an STC for the M20, C-177 and PA28Rs. It's a 200 hp replacement with a few more horses. The FWF is a mod that an aftermarket company has produced with mixed results. Some have had success, but others have not. PM Globemaster, he'll give you an earfull. Quote
Parker_Woodruff Posted May 4, 2009 Author Report Posted May 4, 2009 No I was just forwarding on the info for owners who are considering upgrading...however after finding out on another post what it involves, I won't exactly encourage looking at it! :-/ Quote
