Also, some questions regarding your testing methodology:
1) What are the timed runs? Like Run 1 at 6pm and Run 2 @ 6:10pm? What's the spacing?
2) Where is the air fan? How do you position it to simulate - approximate - real world air conditions?
3) How did you reset the ECU? Did you test stock after each of the new intakes? When we did a dyno run of the Mazda3 intake, we found that the first run was the best, but the subsequent runs were heat soaked due to close spacing of the runs - within 5 minutes of each other.
4) What gear were you in? or was this an Auto?
5) Do you have any subjective "sound" results?

2) the fan was placed infront of the car and is about a 35mph fan that is 3 feet in diameter.
3) First we used a code scanner to see if there were any codes thrown during the previous test. we then pulled the ECU Fuses for 5 minutes or so while we exchanged the intakes.
4) stick and in 4th gear.
5) uh no but there is some blood on the finder i left from my left hand where i was trying to get a pipe through. want me to take a picture of that for you?
6) if your interested in sending us an intake to compare to the Injen we will be more than happy. Will I go through doing another test like a round 2 not untill my hand heals from the cut issue. But send it and we will return it when we see how it stacks up.

Already on it.
Much appreciated GSC. Very nice work.

OK could someone explain HOW and WHY the SR version of the injen performed so much worse that it's CAI sister.
The only difference is a foot of curvey pipe.
How in technical terms could this affect the A/F mix, how could it affect the MAF.
Surely once the air reaches the SR position in the pipe it's the same air doing the same thing. It's just airflow in a pipe, right.
It doesn't make any physics sense, atleast not to me.

I mean ( I'm no car expert) but the more I think about this the more I think it's a flawed test. And I love you guys so don't take this the wrong way.
My understanding was that you needed a fair amount of drive time for the Ecu to adjust to the changes A/F levels and the Maf readings. It's not going to get that from a 10 minute cruise.
In essence what you are testing here is which intake can the ecu work with best with little or no 'learning'.
Or have I missed something?

I can tell you that coming from the WRX and Evo forums:
Injen intakes are generally good. They provide close to stock A/F.
K&N intakes are always terrible for A/F. They do no R/D it seems.
Weapon R has not been tested much
