I received an email from Cirrus this afternoon announcing the SR22T. Any word if TCM is working on a TSIO-550 as an aftermarket upgrade for Bonanzas?

So, this is the TCM TSIO-550K.

I can't imagine why anyone would want it, if it were available as a retrofit for a Bonanza.

The TA Turbo setup has better economy, is faster, and is a proven design.

There's a reason people take the B36TC and have the TCM turbocharged engine out only to put in a TA Turbo engine.

It says it's a Tornado Alley Turbo IO550.

I thought it was going to be TCM's factory TN set up.

The video clip on aero-news.net says Cirrus is going to offer both TAT and Continental's turbo at the same price point.

The Continental TN is rated at 315 HP and they reduce the RPMs to 2500 to lower noise. They claim the new motor is significantly smoother and they have integrated the Garmin Perspective to establish easy LOP settings.

They demonstrated 186 knots at 10,500' with a FF of 17.5 GPH.

That's how fast I go in my Bo at 10,000.

Yea, my Baron is about the same slow speed at 10K.... so I start the second engine if I want to go faster..... <g>

The TSIO-550K probably will be limited to 65% power for LOP ops.

Here's the deal:

TAT TN Cirrus = faster, cooler, less fuel. What's not to like?

TCM TSIO-550 Cirrus = slower, hotter, more fuel. What's to like?

If anyone cares, TCM is not giving out the truth about this engine and what it will be able to do at their booth at the Cirrus Convention.

I kinda wondered because the speed demonstrated didn't blow me away. Cut the preformance to 65% to save heat isn't any amazing feat, and the video showed they still had pretty high temps.

The Cirrus crowd is attracted to simplicity, which is where this package shows well. It's easier to market, but I think we (here at BT) tend to be a lot more of a techcically driven crowd and is willing look deeper at specifics.

I just hope TCM doesn't play the warranty game with the TAT application.

Cirrus changed the nosewheel linkage on the SR22T to give extra cooling under the cowling. It's not very attractive, but obviously necessary.

It would be interesting if TAT would tell us just how many B36TC owners have actually converted their long wing, factory TC to a TN version. I doubt there is more than a handful. Everyone seems so quick to bash the factory turbo installation but most of the actual 36TC owners I have spoken with are pretty happy with the installation and performance. The ABS article and reviews on the 36TC planes a couple of summers ago seems to reiterate my point.

I think TN is a great way to make a NA plane better. I can't see how it adds $100k value to the factory TC installation. Where is the ROI in that?
