Today I was able to put my 2011 NON-PP SHO on the Dyno today. I've got some quick notes/points I want everyone to understand before continuing my experience. (All mods are in my sig and up to date)
1. I was on a DynoTech by Dynamics AWD Dyno at Turn-In Concepts in Cincinnati, OH (www.turninconcepts.com). They specialize in Subaru primarily.
2. I used a freshly cleaned and oiled AirAid intake and the MDesign intake (which is about 2-3 weeks old?)
3. Each run started in 4th gear, and then around 2000-2300 RPM the car was W.O.T. The only reason was because if you hammer it in 4th going not too fast... the car down shifts into 3rd. But from the looks of, the graph is fine. The Hood was fully shut also!!!!
4. Each run was data logged (using torries SHO data log config file) so I have some numbers to back up my findings on temperatures and such. I am MORE than willing to provide anyone with the logs I have to see the differences.
5. When this was published, I had not spoken to anyone, not MDesign, not Torrie, no one. I want all of this to be my own words before anyone has any opinions or thoughts.
6. I will admit, my heart is broken by the dyno of course... but this testing was to help out MDesigns and to prove the difference between his set-up and the AirAid setup. (if i were to add 15% of my max run, it puts me at 340hp, that makes me happy inside... lol)
SOOOOOOO to the meat and potatoes of everything!!!!!!!
MDesign Intake
I started out with the MDesign CAI on first. I had 3 runs. (Torque was not displayed, but you can see the very small changes on the graph)
Numbers as follows:
-294.6hp (Run Not Graphed)
-293.6hp (Torque around 342)
-298.3hp (Torque around 348)
Tuner’s thoughts – Any way to possibly make the filter larger, could help with more flow. (Not too sure if this is possible, what calculations were based off of, ect. I’m just throwing this out there for everyone.)
The Dyno graphs I was provided for the MDesign were the 2 most uniform graphs with no hiccups or anything. I assure you though; they all looked almost exactly alike.
AirAid Intake
Next up was the AirAid Intake. I swapped the Airaid intake in and did 4 pulls with it, 3 of which you will see Dyno graphs for.
The first run was fairly cool temperature wise. So the last 3 is what matter most in my eyes (Real world scenario). Numbers as follows:
-292.8hp (Torque around 348)
-292.2hp (Torque around 352)
-301.8hp (Torque around 350)
Now seeing how the 2 intakes match up, I received a graph of the highest pull from each intake. Note, 3hp difference… in my eyes they’re equal
TEMPERATURES
But what I feel that is most important would be the temperatures I saw. If you check out the OPEN ZIPPED FOLDER TO VIEW MY LOGS AND THE GRAPHS FOR THIS SECTION You can see that in intake temps were virtually 100% consistent throughout the entire run on the MDesign vs the AirAid… But…. Look at the “Charged Air Temps” The charged air reaches 55+/- *C (or 131* F) on both intakes! (note, for AirAid, view pulls 2, 3, and 4 due to the first pull, the engine was quite cold compared to the other 3) You can see how the airaid (NOT MODIFIED, INSTALLED PER INSTRUCTIONS PROVIDED WITH THE KIT) soaks heat like no one’s business where the MDesign does exactly what it is supposed to do.
I’m also beginning to think that the Intake Temperatures were higher on the MDesign intake due to the location of the sensor vs AirAid sensor location. The MDesign location is much closer to the engine where all the heat comes from.
Conclusion
I see no HUGE gain on the MDesign intake vs AirAid intake other than looks. Airflow seems to be better than the AirAid or the stock intake based on how air physically flows. Me personally… If you have not purchased an intake, just save the $$. Although, while getting an oil change recently, the tech saw my intake and took like a quadruple look then looked and me funny. Needless to say, he probably fell in love with the design of the MDesign intake.
I will add though. For customer service I will say “MDesign > AirAid” all day when it comes to support.
