Lycoming vs Titan engines
Hi all
Currently I am doing a lot of study on my next aircraft and am leaning toward the rv4. Has anyone fitted the Titan 320 or 340 stroker to the rv4 and if so have you experienced any problems eg cowls? As an engineer I've cut my teeth on certified lycomings and believe there is a lot of potential and areas for improvements. My preferred engine for the 4 is a worked io320 eg port and polish, emags, 10:1 comp, nice exhaust, Sam James cowls with high flow filter etc and the Titan comes with a lot of these goodies if needed! Any help would be great!
James

James,
ECI's new assembled Titan stroker motors are quite a value. I think the 340 is the perfect choice. Our team just started installing some of these motors. Your choice of custom accessories, colors, and the power to weight is compelling. It will fit no problem in your RV-4. Holler if you have any questions.

James & Kahuna, I'm very interested in the Titan O-340 also. I've got an O-320 presently that purrs like a kitten and I'd be foolish to change. However, my druthers would be to have an O-360 and I daydream a lot.
As a practical matter though, if and when I really needed an engine, I'd be better off to switch to the O-340 or a 170+ hp O-320. I have a James Holy Cowl and I don't want to re-do it. I could conceivably just switch to one of the other engines and not have to modify the cowl.
Mel Asberry has a 175/177 hp O-320 engine in his -6 that he's real happy with. You might want to search his posts for more comments regarding that engine.
I subscribe to having as many horses as you practically can, even if you don't always use them.
Please keep us posted on what you do James.
Cheers,

I am also building an RV-4 and I am thinking in engine installation.
I almost decided for an IO-320 because of weight of IO-360 and associated propeller.
Now I see that the IXO-360 which Titan sells is lighter than Lycoming stock.
ECI states its weight is 254 lbs. without accessories.
Who really knows the actual weight difference with the Lyco IO-360?
And how much is the price?

Performance Engine Life
As an observer only as i dont have the plane building experience of you guys, I have a couple of questions.
1. How would the io 340 go in an RV 3 ?, mini rocket i think.
2. What sort of engine life are the guys that soup up engines and run 10.1 pistons with the head work and cam shafts etc getting. Do they still run out 2000 hours ?.

I have 850 hrs. on my O-320 with 9.5:1 compression. So far my compression and oil consumption remain the same.
I run a 3-blade Catto prop and don't "push" the engine. I typically cruise at 60% power.

Guys, about what is the cost of an eci strokes? I am getting closer now and starting to look around for an engine, still leaning to a new one.
Thanks

Barrett Engines - excellent value
Everyone looking at engines should look at Barrett Precision Engines - they will build you anything you want and there are a lot of added value items included. Check their website: http://www.bpaengines.com/site.html
And then give Rhonda and Allen a call - they are great people!
And I'm not sponsored by them or related! I just got a great, custom engine at a very fair price!

Thanks for the info and insight. I know some of the earlier eci's had problems with ring delaminating. Paul dye experienced that, but I think that has been resolved. Eci does look like a good value as do others. A lycoming just seems a bit higher in price for the same. Of course engines are my weak spot without having as much experience with them. My mission is low maintenance and high tbo, not really highest power.
