Higher compression pistons. Acclaim is actually turbo charged, not TNed. About 1.5gph difference at lower power settings. That's about it. Also, if Tornado Alley actually built it, it would be much higher quality setup than anything from continental. Their Cirrus setup is a work of art compared to the Continental TSIO powered Cirrus. Everything is just better thought out. Little things, like hoses, heat shields, etc, etc, etc...

Along with a pile of recurring SB and regularly worn out parts, other than that the TATI set up is OK. As a shop owner they are really good!

What parts? I'd like to know what parts of their setup wear out quicker than that of the continental setup? I bet you none if both run at the same TIT. Most Acclaims are needing a top at 500 hours if run by the book too. It's like the Bravo story all over again. At least the Cirrus cowling was designed by someone with an engineering degree.

 

If you're referring to the 50hour exhaust inspection, well, that's just a good practice for any turbo'ed bird.

My J gets a 50 hour exhaust inspection by me...important stuff...

GAMI/ tornado alley is top notch.....

If the damn government would get out of the way we could install there cardinal turbo system on our Js. Same engine. My 165kt J would be a 190kts J.....

On the TATI install on an SR22 all of the turbo support hardware, tie rods, tie rod support fitting and bushings, bolts etc. wear constantly. I've maintained Cessna turbocharged twins for more than 30 years, their system has none of these type of parts to wear out, because they actually mounted their turbo more substantially.

We have an Acclaim with almost 800 hours, with only one cylinder removal due to a bad ring, he runs it per the APS methods.

On all of our turbo aircraft we shoot for 25-30 hour oil changes with an exhaust inspection, pressure check and lubrication, its best practice for reliability.

As to cowling, since the J, Mooney has built the best cowling, stop by a Cirrus shop and check out the differences. Cirrus is thin flexible, early ones are one piece lower portions which are difficult to fit around the nose gear with out scratching some thing, later ones are two piece equally thin and are held together with a dozen 8-32 screws. Cirrus should have their cowls built at Mooney.

I was referring to cooling airflow flow. I don't care how flimsy it looks or feels. It works, it works without cowl flaps, it's lighter, too.

The TAT set up on a Cirrus is high maintenance. It eats right side wastegates due to a clevis geometry issue, it eats both exhaust manifolds due to cracking in several places, the manifolds can seize and then blow out at the forward expansion joints after only a few flight hours since last inspection, the turbo mounts wear and break, the bypass pipes leak profusely ( they use the term "jiggle-fit" to describe the normal fitment) and dump exhaust all over the engine mount and the cabin air hoses, the exhaust heat "shields" are actually heat concentrators because they focus energy back into the pipes, instead of away, like Continental does,  the intercoolers crack at the mounting bosses, the induction manifold hoses are high maintenance, the pressure regulation is very finicky and requires constant adjustment if you operate from hot to cold climates.

 

I maintain some of the highest time Cirrus TN's, including the Cirrus with the most time operating at FL250.

 

The Continental TSIO-550K uses a tiny bit more fuel but is a far superior engine, and is easier to maintain since it was purpose built, rather than grafted-on after the fact. Continental spent 5 years developing the installation for Cirrus.

 

But, I do have one kid still in college, so please, buy a TAT equipped plane today!

I see you finally bit the bullet Joe, congrats!  I knew you'd enjoy those climbs...  As to my old post with the numbers, it's somewhere here in the Modern Mooney forum but it's old...  Should have been a post around 2007 - 2009 since I sold my Acclaim in '09...  I'll look if I still have the numbers file and if I do, I'll re-post it.

 

Regards.

Roberto.
