I took my plane outside today after 4 months of being inside doing the
finishing.  It is now ready to be primed, and the weather is good, so I took
everything outside to work on it.  It had been 4 months since I had last
started the rotary, and it hadn't been started since I plumbed the turbo
into the intake system, so I was anxious to see how that was going to work
out.

The engine started after about 2 revolutions, and though a little rough to
start, smoothed out nicely.  The mixture gauge shows it's a little on the
rich side, but I hadn't done much tuning on the EC2, since the turbo was
connected up to the intake yet.  I'm going to have to read Tracy's
instructions again on how to do it, so that I get it running a little
leaner.  It's so rich that the control seems to have little effect.

At ant rate, I ran the engine 2 or three times, topping off the coolant each
time.  On the third run, I ran it up to 3500, for a few seconds, and then
back down (it's idling about 2000 rpms).  The next run up, I ran it up to
4000, and with the brakes locked, the tires started sliding in the grass.
WOW, does the turbo add power !  I'll run it some more tomorrow, but I'll
take it to the driveway, which is asphalt before running up too many RPM's

I can't wait to fly this thing.  It seems to have more power than I imagined
it would, and it should scoot down the runway pretty good.

Congratulations Steve. Looks like you are getting close to first flight.

Looks like Steve's engine is the second engine to run with our intake manifold.

Steve,
Do you still have the oil cooler mounted horizontally near the firewall? I'm not sure you will get enough airflow through it oriented like that.
