TPE331-12 Cessna Caravan Upgrade

The Honeywell TPE331 turboprop engine provides up to 30 percent more power, reduces fuel burn by about four gallons an hour, has a faster throttle response, and costs as much as $40 an hour less to operate than the production motor on the Cessna Caravan. This video demonstrates the difference between the 900 horsepower (HP) TPE331-12JR engine and the 650 HP production engine from another manufacturer, care of Texas Turbines, one of Honeywell's authorized channel partners who provides engine upgrades for the Cessna Caravan.

@dxk239 Thats why they have sold so many - not! Maybe 4?

Why does no current OEM use the Honeywell engine? FOD damage. No bypass = if you kick up rocks reversing on landing, engine suffers moderate/severe damage. That's why nearly all twin turboprops with the Honeywell are high wing airplanes. (Commander, MU2, etc.) I flew a T-Commander years ago and took a small bird strike injestion. End result - 2 months downtime and $80,000 repair bill. Took 4 birds in a King Air C90 inlet - no damage to the engine, just a lot of feathers to clean out.

Check out the Blackhawk Upgrade with the -42A PT6

But what's the difference in fuel consumption between the two?

Not bad performance "For a Fixed Wing!" LOL ;)

Great filming guys, really great, some serious Horsepower there!

Have to agree its nice but it was built by a bunch of texans.The alaskan builder does it beter.
