My saying is " If the results differ from the theory, believe the results and invent a new theory" !! Math/science doesn't lie !!

That's impressive. Is it this setup?

Nice! Now you have your baseline, you can probably evaluate the IPD plenum better in the future.

Well the IPD will have to wait a little. My Porsche fund just dropped a whole lot. It would figure that after i just did the water pump with LN tstat and OE coolant (with Ahsai amazing flush write up) the left rad would decide it was at it end of life cycle. I just ordered a pair of these!

Also wanted to point out that i DID get oil temps using my Snap On scanner. I could not get it with my Torque pro app

Yes because the Snapon scanner also use Porsche specific protocol to communicate with the DME. If a scanner reports cam deviation and oil temp, it uses Porsche specific protocol. I think more scanners are capable of doing that now e.g. icarsoft scanner.

too bad it won't show ignition over rev counts. Not that i really care. Just figure it would be nice to compare as everyone always post about it.

Fabspeeds response to my asking the ID @ the MAF. "The oval part of the competition air intake is 3.6” x 3.1” "........

Is it oval shaped at the cross-section where the sensor hole is? 3.6 x 3.1 = 3.350 circumference, that's only 0.028in larger than the stock MAF housing.

A 0.028 larger than calibrated MAF housing would result in a slight "under-reporting" of the Mass air flow. So if that measurement is precise your flow numbers are plausible, if not slightly "under-stated".by 3%..very interesting !!

3.350 / 2 = 1.675rE4 = 7.87
3.322 / 2 = 1.661rE4 = 7.61
7.87 - 7.61 = 0.21 / 7.61 = 0.03 x 100 = 3%

I would believe it could be oval. The MAF is located right at the end of where the two "intakes" meet.

Is there a "divider" inside where the two intakes meet? Does it extend near the MAF sensor? I'm loving the design, and looks like the flow numbers are plausible, and the fuel trims being near 0 back that up...

They say on the web site that it interferes with SAI and engine comp. fan on the 99, that's a shame, but looking at it I can't see why it would interfere..

Just speaking from opinion i would expect to see dividers up to a point. It would be needed to help tunnel the air and not making it just a huge disturbance. I wish fabspeed would join this thread!
