Paul, Can you give me the flow rates for the Mazda yellow injectors
please?

Neil. Ungar

I don't think I have anything official.

This is from https://www.rx8club.com/series-i-tech-garage-22/fuel-injector-info-150432/page5/

------------------------------------------------------------------
more accurate data for the yellow P2/Secondary injectors:

Flow Rates:

450cc/min at 3 bar

486cc/min at 3.5 bar

524cc/min at 4 bar

[524 cubic centimeter/minute = 8.305  gallon/hour [US]]

[51.9 pounds per hour at 6.25 pound per gallon]

[At  a BSFC of .5 pounds per hp that is like 100 HP per injector A lot :-)
Full rich full power it is .65 BSFC or 80 HP per injector.
Or 320 HP about right for a p-port at 10,000 RPM :-)]

Resistance: 11.8-16.5 Ohms

Voltage: 8-15 Volts, Nominal 13.5 Volts

Amperage: 1.0 Amps

Pressure: Min. 36 PSI (2.5 bar), Max. 101 PSI (7 bar)
---------------------------------------------------------------------------------
Some electric pumps won't put out 100 PSI at these kinds of
flow rate and pressures so check your pumps.

The TTC electric boost pump pressure would drop way off to
about 50 psi when we asked it to start the TTC engine.
It would however start. Then the mechanical pump took over
and gave us 150 PSI.
