Dennis,
I don’t think that doubling thing is supposed to happen
except for the fuel flow thru the other set of injectors. I certainly
could be wrong tho. I don’t know what would happen to mine above 7500 rpm
because I couldn’t get there if I threw it off a cliff!
:>)
You lost me with the 540 CC secondaries thing at the
bottom. Did you mean 840 CC?? Your intake was similar to mine.
What did you do to change it?
What is full static power?

I agree that my Renesis engine was only
producing about 70-80 HP on the small red primaries. When I run only on
the primaries with the secondaries off and the
cold start line
grounded my EM-2 tach RPM doubles - 4000 RPM shows up as
8000! My fuel flow numbers and HP numbers appear also to be
doubled!! The 140 HP probably was actually 70 HP!
However - when I operate with the primaries off and the secondaries on the RPM and other data is not
doubled!! Somewhere above 7500 RPM the RPM number on the EM-2 goes
to Zero (0). Is this due to the rev. limiter
Tracy may have
included? If so - does it control engine speed by disabling the
secondaries?
After the fatality several years ago because an apparent
injector may have been disabled by foreign matter, I was determined to have duel
injectors and ignition for each rotor. This morning I replaced the Renesis
red 295 cc primary injectors with blue Renesis 495 cc injectors.
When
running with the secondaries on (540 cc I believe) and the
primaries off I get full static power. Because I've changed
intake and injectors I will need some time to calibrate fuel flow before I can
accurately report static fuel flow numbers.
