Too Much Horsepower

Jeff, I regularly fly my 310HP Ovation from Las Vegas to Houston. About 6 hours  or so in the air, although I like to make a leg stretch stop in Roswell. anywhere from 12-17k altitude, true in the mid 170's between 10.5 and 11.5 GPH. Great birds. I've always wondered about the Fuel efficiency of an Acclaim S - perhaps the acclaim drivers can shine some light on it. Agree with @donkaye- the 310 HP makes a big difference in the Ovation in terms of T/O and climb particularly when its hot, high and heavy.

I'm assuming that one could fly an Acclaim S in the low teens and similar settings to an ovation or does the turbo make it much more thirsty? West to east, getting into the FL's would be great, but certainly not the other way.

Typically LOP 28’/2400  at 17,000 14.8-15.1 gph at 1580 TIT. Around 200 kts

Mine are similar maybe a little north of 200, tough to beat the efficiency

So... about that "Too Much Horsepower" apostasy:

Took off from Middle Tennessee the other day with a full bag of gas and after reaching 100AGL decided to see about a Vy climb.

2000 ft/min never gets old, but the deck angle was a bit much.
