Hi Paul,
Hope you and your spouse had a great vacation in the warmth of that
island paradise while the rest of us froze our bippies off. Welcome, back.
Just wanted to let you know that I got the leaking coolant seal replaced
and have nearly completed the break-in run-up of the engine. On the second
day of the break-in I am very ecstatic to report that I achieved a static
RPM of a solid 5600 rpm! with my 68x72 prop (same type prop as Tracy Crook).
The old engine could do no better than 5100 with the old intake manifold and
might have hit 5250 with the new intake on the old engine before it crapped
out. But, the 91 Turbo II block and new intake manifold appear to really
like each other.
The engine increased past the 5000 rpm point as if then engine was
finding it easier to accelerate once it reach 5000 and I am guessing it
might be the dynamic charging starting to take effect. Indeed, I stopped
pushing the throttle in when it hit 5600 rpm (couldn't stand the thrill),
but it felt like it easily had another 50 to 100 rpm left in it. I have not
been back out to run up the engine due to the nasty weather and other
commitments. Hopefully, after Christmas you will bring back some warmth
from your vacation and I can get my annual completed and get this thing in
the air.
Best Regards
Ed Anderson
We sure did Ed. Thanks.
