Dyno testing of the MMR CAI is complete and the results are dissapointing to say the least. ALL DYNO PULLS WERE DONE ON STOCK TUNING. Airfuel measurements were taken post cat with a wideband.
Hot off the street with the stock airbox the car made 365.69/345.39 SAE, stock tuning. Backup pull 5 minutes later 366.31/346.72.
23 minutes later after installing the MMR CAI..... 375.60/337.30 but those hp numbers are misleading. When you see the graph you will understand why. The car is down on power thruout the entire pull and there is a spike at the very top that gives that max hp number. Tq is incredibly down with this intake the entire pull.
Backup MMR CAI pull 5 minutes later 370.54/329.05 with the exact same spike and down on tq. The backup pull to that one is identical.
Spent 5 minutes putting the stock airbox back on and got.... 368.53/350.57 and the spike was gone plus torque was back up 20.
Its a nice fit and finish CAI but they obviously built it with CA emissions in mind because I had one extra fitting at the metal elbow that needed to be capped off (no cap included or mention of that in the one sheet instructions). Also there is no hardware or instructions to secure the heatsheild to the fender and it does not pull air from the stock airbox feed tube. Overall I would rate it a 3 out of 10 only because it looks nice but does not perform anywhere near as advertised.
Some youtube video's will accompany this information later.
I have attached the graphs with as much information on them as possible. Now its on to the next product to test and to continue our WMS Custom tuning that we started immediatly after the CAI test today with some very promising results that will be posted later.
Thanks,
JJ
