Glad to hear its going well, Steve.
Well, watch the temps if you kick up the go juice - a cooling system that can handle X HP may not handle X +Y HP {:>) (He said as he enlarges his smallest inlet after putting new engine in and finding it produces more HP). I think your being wise to go easy on the stock turbo - its simply not designed for this application as several have discovered. But, sounds like you are babying it so will probably do OK.
If you like the turbo - then I think going with a T04 with the right A/r is probably a good idea.
Well, hope you drop in at Lumberton whether driving or a foot.

Ed,
I don't beleive that I'm going to make the flyin.
Flying has gone exceptionally well this week. I have
flown over 4 hours in the last two days, and I plan on
getting in at least 2 more hours tomorrow, before
heading back to the Raleigh area.
I am very happy with the way that the rotary is
perfoming now. Temps are good, and it is very smooth
accross the power range. Most of my cruising around
has been at low cruise. About 4400 RPMs and proabably
about 55%=60% power. Trying to conserve both fuel and
turbo.
I'm also considering removing the turbo, as I see it
as the weakest link. I have most of what I need to
convert to a T04 turbo, but wondering if I shouldn't
just go to N/A. Still kicking it around, but probably
won't do anything untill I get the 40 hours flown off.
Just over 20 hours so far, but going strong,
especially if I can get to over 6 hours in three days.
It has been pretty bumpy up there, especially this
afternoon.

Thanks, Steve
Great to have my aircraft back in its hangar with
thunderstorm season
beginning.
Going out today to enlarge the 10 sq inch inlet left
duct opening to around
18 sq inches
Are you going to the Mid-Atlantic Flyin? Sounds
like you are getting your
time burnt off - bit by bit.
