New Cylinders....which ones?

[sstocker31]

Thanks to all that have replied, your imput is appreciated.
I had decided on the ECI Titan jugs as my choice, it seems that most of the ones with the failures are the big bore Continentals, and not the smaller Lycoming 320's.

With everyones input though, I will take another look at the Lycoming factory jugs....

Thanks guys....

I have a IO-320 ECI built by Titan three years ago. Love the engine, break in was quick and oil consumption is 25-30 hrs per qt.

For ten years I struggled with ECI cylinders. Delamination of rings after about 300 hours, oil consumption always high. Last spring they were rebuilt again and in 60 hours, never broke in. After 50 hours of blow by I started to make metal. 10 hours later, more metal, and we pulled a jug and found a cam bad. It had been fine previously, and I blame contamination of the oil with blow by and delaminating rings.
I used the recommended oils and breaking procedures each time.
The engine has been rebuilt, cam, bearings etc, and six brand new lycoming jugs

Break in was normal, low oil consumption, and a clean belly for the first time in ten years.

Not all ECI Titan Cylinders are made the same. Here we have the ECI Titan STEEL cylinders with low oil consumption (like I have) and ECI Nickle+Carbide cylinders that use lots of oil. (or at least everyone I know that used them has had high oil consumption at some time between overhaul)

In addition to the two different cylinder barrel interior surfaces, there are also two different exterior barrels that ECI uses. Have not heard of any difference in the exterior barrel with tapered fins having issues other than the weight they save.

I am of the opinion that that the Nickle+Carbide cylinder barrels should be avoided on airplanes that are flown regularly. The only advantage may be better corrosion protection in an engine that resides in a corrosive environment and not flown regularly.

my Superior cylinders have been great from day one. break in was accomplished in the first hour, 1 qt oil used every 25-30 hours since. 380+ hours and going strong. I would definitely buy them again.

Same here.

Has anyone tried the AX 50? http://www.heavy-fuel-engines.com/wp.../ACE-AX501.pdf

I would also be keen to know what people think of these AX50 cylinders? I think the AX50 cylinders are what ACE use on their engines. On paper they look good.

Hey welcome to VAF, I was talking to Kevin Eldridge about his setup and almost went that route before I found my engine prop setup, if I had the extra money I would have went that route, I like the design and maybe after some time on his engines get logged, I might try a set. He is making some good HP #s

Forrest, how about posting the bottom line street prices you've been quoted in your research?
