Well, that is good news, do you attribute your success to the general installation overall, or did you do something in particular (different than others) to generate this success?

Quite a number of people who've stuck with the Egg conversions are happy with them and they are working well with minimal problems. I think the people not in the actual loop think they were all a disaster which isn't the case. I can count over 15 people who correspond with me fairly regularly who have something around or over 400 hours now on them. Pretty much has just been oil changes and spline inspection/ lubrication annually. My customer in Norway likes his turbo six enough that he's doing another one for another aircraft now. People love the super smooth running, easy starting and minimal fuss when flying. You do have to have the rad setup working well but most have that licked and there are few issues in hot weather.
The Subenews forum has been invaluable as stated before to identify common problems and fixes. The people who've implemented what's been learned have generally had pretty decent service from their packages. Lazy people who don't do the spline maintenance or listen to other critical advice (like ECU programming and checking timing offset) have often had plenty of tears but I can say same the same thing for many other auto conversions I've assisted on too.

I'm sorry, but advancing the art will require at least some fundamental understanding.

I call it a dual mass flywheel because that is it's name. The second mass is the plate that has the female splines, the splined shaft, the rotating part of the gearbox and the propeller itself. The function of the thing is what we care about. I don't know if a damper is the proper term, but the springs allow the second part of the flywheel to rotate many degrees (maybe 60 degrees) from the crankshaft portion. This means that the impulses from the crankshaft cannot be transferred to the gearbox except through springs. It's like trying to hammer a nail with a spring faced hammer. It preserves the gears, bearings, and prop hub.

I haven't done anything special regarding the installation. As Ross has noted, there are plenty of successful installations. Like anything else, you don't hear much about the successes, but the problems are big news.

Yup, Dan deleted a couple of his own posts. Not sure why.

Alternative engine.... not for the lazy.
Not for those with lack of ingenuity.
Not for those without some degree of skill.
Not for those who aren't willing to continue learning.
Not for those without intense attention to detail.
How would you like a really long lesson in patience?
How about another lesson in focus?
Determination?
Faith in one's own abilities?
Can you search? Can you read?
How about networking?
Did I mention patience?
I'm getting closer though.
Maybe I too will only get 16 hours into phase 1 maybe less. I decided to go down this road-- I'm going to carefully see where it takes me.

Vans rv7. Mazda 13b turbo. Reserved---N713BT.
IF they gave a S--t here about putting my configuration in the signature it'd look something like this
Tracy's rd-1b Ec-2. (need an EM-)
Mount by Ed at tech welding.
Greddy S5 exhaust manifold
t04-b V 1.15 A/R hot side
Manual waste gate
Cold-side mount denso alternator w/ external regulator
top-mount standby alternator
Griffin cold-side mount radiator
CX Racing 30 row oil cooler
Davies-Craig EWP and controller
UHS spinner
IVO 3 bladed magnum
All fits under a Sam James holey
I spend more time over on the Lancair online flyrotary board. Though I like the functionality of this board (including the search function) I try to stay away from the drama. I was called a Troll here on this alternative engine forum-- so now I stay under the Bridge.
