George,

I suspect that is a typo.  We will see when Dennis responds.

Dennis,

 I am trying to follow this thread without knowledge of the mentioned injectors, so could you tell me what color are the 540cc injectors and are they Mazda injectors?

TIA

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.
