Paul,

Does the P Port require a plenum in front of the intake runners.

The video of the RX 8 P Port with carb and vapor cloud above the carb was a
indicator of a potential hazard.

What material can be used to build the plenum with respect to fire potential
(glass composite flammability)?

Re installed the engine into the airframe and the sensors and brackets clear
everything.

Aluminum would be best. We have used fiberglass.

Paul,



Does it need to be a specific volume?

How did you measure air when you tested the MAF sensor to get the curve?

I would think that one should test the unit to determine the curve.

What was your test set up?

Joe Berki

We used Tracy's EFI and that used manifold pressure rather than MAF.

You have been on here a long time. I am sure you have these pictures :-)

BTW turn off the double line spacing on your email editor.

Paul,

I had a computer problem about a year ago and lost most of my pictures.  Let
me know if the double spacing issue has been solved.  I was following that
13b P Port on that RV8 and I believe it suffered an accident early on in
testing.  The pics that you sent are on your web site.  The other question
was what was the test set up to get the curve for the MAF sensor that is
also on your web page?  Did you use a MAP sensor in tandem to get manifold
pressure and convert it to mass flow?
Thanks Joe Berki

That was a Mustang II.
I have never used a Mas Airflow Sensor. The Motec uses the manifold pressure
and a O2 sensor and several other sensors.

Tracy used manifold pressure and intake air temp.

Paul,

Did the MAF data tables that depict air flow vs voltage on your web page
come from Ford?  I forgot it was a Mustang II.
Joe Berki

Yes.
