There were also GO 480 versions and GSIO 480 versions. I've heard all kinds of scary stories from people who have not actually owned and flown the GIO series of Lycomings, and then I've heard from a few folks who have flown behind them who really like them for smoothness, quietness, etc. I'd be quite comfortable owning and flying a GO 480, but I'd be really interested in talking to someone who as actually flown behind GSIO 480s or GSIO 540s about their experiences and any idiosyncrasies related to the supercharged versions.

Over the years our list has hosted great discussion on the pros and cons of these and other Commander engines...particularly relating to 'caring' for geared engines. Maybe it is time to re-visit those days with the 'promise' that no mention of sumps occur!

I can tell you that it is one powerful machine! The times on my engines are 350 hours and 10 hours on the props. When I fire the engines up I can hear a little clanging going on due to the props but after it is warmed up and about 1200 RPM the props are loaded and you don `t hear anything from the gears. My oil consumption is running about a third to half quart an hour. It seems to be coming from the breather tube and not burning any at all. I think maybe I `ll try an air/oil seperator. I have had nothing but a good experience with the engines thus far. I also have an Aztec with IO-540 (250 HP) and I have flown that airplane to TBO 2,000 hrs. and have only changed out two cylinders. It is a GREAT engine with no bad habbits! Hope this helps.

Even engines that have been sitting idel for many years come back to life and perfrome great. Here is the skinny. The GSO 480 is a GERAT ENGINE!!! they almos alwas make or exceed TBO (1400hr). They are very smooth and very strong running. I drive a 1967 SS 427 El Camino (among other old muscle cars) and the Commander will out run most of them on T.O. The engines have pressure carbs (think throttle body F.I.) These are very depedibal and relatively inexpensive to overhaul. Now for the bad news. The geared, supercharged engines can be hurt by miss handling them. If properly flown, no problem, fly them like their direct drive brethren, big problem. Learning to properly fly them is no real issue, but does require a bit of training and discipline. I have no real experience with the IGSO 540 but have heard little good about them. I am aware of several premature failures and they seem to seldom make their TBO (only 1200hr). jb ************************************** See what's free at http://www.aol.com. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message commander-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Commander-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/commander-list Browse Digests http://www.matronics.com/digest/commander-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
