Scott,
After its installed, right click on any picture and
select resize picture. It will allow you to select what size you want - I
usually select the smallest for attaching to email.
Hope this helps,

Dave;
Sorry to hear about the
Turbo...
I ran my engine again today after working on air guidance
for the oil and radiator outlets.
I'm running a Turbonetics symetrical TO-4
turbine with Inconel turbine wheel. It has a 60-1 compressor, P trim and .61
A/R. I hope it will withstand the heat.
Greg Richter was using the
same when he had a 13b in his cozy. I talked to him one day (so long ago) and
he reccomended it, so that's what I got. I suggested some model of waste gate
and blow off valve, but he said to forget about it unless operating it
indicated a need.
I built up the exhaust manifold from two 2.5" .060
wall 321ss elbows curved up to the turbo flange in a short fat 'Y' to hold the
turbo close to the engine. Then I welded in 2" to 1.75" nozzles in the engine
flange ehaust ports to keep the exhaust blast away from the flange welds to
the 2.5" tubes that support the turbo weight. I added two 1/2" ss straps
between the flang tops for 'suspenders'.
So far I have only run up to
about 3500 rpm because I don't trust myself or the strap tying the tailwheel
spring to a cedar tree. My highest exhaust temp is already over 1200 F.
I'm
using a CATTO 2 blade left hand equivalent for a 180 Hp O-360 prop. We figure
it will be right for the test flights and absorb 200 Hp @ 2900 RPM. Any more
power would be risky for the RD-1A gearbox, so I have not added an intercooler
yet either.
I'm waiting for the summer air show season to get over before I
send the ECM and EM to Tracy to figure out why they dont talk to each
other...He's bound to be busy now, and I can still run my engine to test
cooling and other issues, what ever they may turn up to be.
I tried to post
pictures of my turbo setup on the FLYROTARY list, but they didn't go thru. How
do I reduce the size of picture to file the file limit?
Oh, and you
can upgrade my file on your rotary roster to 'ground
running'.
Regards;
Scott
PS I would like to suggest that all of you
post something about your ROTARY project on YOUTUBE and add FLYROTARY to the
title or keyword list, then we can all quickly identify video posted by one of
"our own".
