310HP Conversion?

[Playinmechanic]

I am looking into the 310HP conversion for my 97 ovation.  From what I am told/researched the conversion consist of cranking up the fuel and govenor and adding a three bladed prop.  The stc for this conversion seems to be very pricey.  Already having the three bladed prop up front, I am curious as to weather it really matters as to which one.  Also whos all out there doing these conversions.  I would like to look at all of my options, and possibly which other ones may be out there. Thanks

It is on the pricey side, but in my opinion, worth every penny in the performance increase you see, although on an Ovation is not as dramatic as on the Eagle.  It is my understanding that if you have already the 3 blade prop, the cost is about $8,000 less than the full job I had done, but can't confirm that.   I know no other mod option for the Ovation either.  You'll get a bump to 2700 rpm unrestricted, a new tach, and of course higher fuel flows, but my oprational experience is 195-197 TAS between 9-11K ft., with ff of 16.5 gph 100F ROP.  Not bad for scooting along in that speed neighborhood...

Forgot to mention...  185 TAS @ FL170 with 12.8 gph!!   I know most folks here don't like wearing oxigen, but is easy to get used to it after a few flights.   If you keep a cruise climb of 120kts IAS constant, you'll still see no less than 400 fpm climb rate at those levels.

Another good mod to go along with the 310hp is the addition of long range tanks (130 gals total). You will have 2,000nm range at 175kts. It makes a heck of plane to go non-stop anywhere in the US and abroad.

So what does the conversion cost if you have a three blade prop on an Ovation ?

Thanks for the info guys.  Lucky for me I already have the long range tanks.  As for the conversion I need to do some more research.  I've heard of guys out there having their motors cranked up with out spending the money on the stc, granted you don't get the paper work and the log book entries, your pocket book feels a little better in the end.  Has anyone else heard of this?

I'm going to do the 310 conversion on my Acclaim.  Will let you know how it goes...
