Can’t you set it to a higher
rpm?? 8K is not supposed to hurt the Renesis with the lighter rotors,
etc.

Tracy's rev limiter works. Problem is staying away from it on
take-off with the MT electric prop.

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.
