Dennis is running Siemens 540cc injectors as his secondary's. They are Bosch type and will not fit the mazda block or fuel rail. He relocated his renesis secondary's to the primary position in the block.

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.
