Do you think the Kinsler nozzles would work in the RX8 intake

manifold

injector holes or do they have to be in the main air stream? Karibian


I think they have to be in the air stream.

Paul Lamar ...No rotor no motor.

Perhaps an e-mail or call to them would be beneficial.
They have been very good at problem solving for our
race engines, without a sales pitch. Every system sent
to them for rework and calibration, has come back so
well set up that we hardly turned a screw upon installing.

Karibian,

I would suggest downloading the catalog and looking at the various
nozzles shapes and sizes they offer. If you can find a shape and
size similar to the EFI nozzle on the RX8 engine, I don't see why it
should not work.

The key thing is that it should spray fuel into the runner the same
way the stock nozzle does -- not spray it onto the runner wall
because it's too short or whatever.

The other thing is how you will thread it in. It may not be the same
size hole or thread. If the existing hole is smaller you may be able
to enlarge it and rethread it so the Kinsler nozzle will fit.

Regards,

Gordon.

Gordon,

If the nozzle is constantly spraying then at low idling speeds some fuel is
getting sucked out with the exhaust during over lap.   I can imagine that at
higher speeds this is not happening perhaps as much if at all.   What do you
think the BSFC will be compared to EFI in light of the fact Mazda choose the
later in Lemans.  They were concerned to get the best BSFC since it is an
endurance race.  Mistral and Tracy both say that timing of the injection is
critical for good BSFC.

In either case I want the injector right on the housings so maybe this isn't
an issue.  I am trying to design a way I could test both systems using the
same injector boss.
