MAZDASPEED 3 Dynos: Stock vs MAZDASPEED Cold Air Intake

[Speedy3]

MAZDASPEED 3 Stock vs MAZDASPEED Cold Air Intake - 3rd Gear
MAZDASPEED CAI Cost $325.00

Dynojet Research Dynos were run on 2 different days. Dyno with MAZDASPEED CAI was run on 3-5-07 and Dyno with stock airbox was run on 3-6-07. Yes, I had to take off the MS CAI and re-install the stock hardware! Actually, I'm still stuck with the stock HW cause I don't have time to change it.

Dynojet Research Dyno on MAZDASPEED 3 in Stock Configuration

Atmospheric Pressure=29.80 in-Hg

2 Large Cooling Fans placed 5 ft. from front of car

Dynojet Research Dyno on MAZDASPEED 3 with MAZDASPEED CAI

Results:
10.14% HP (24.2 HP)
10.28% Torque (24.8 ft-lbs)

Averages:
3/5/2007 with CAI-Dynojet
HP:263.2

HP RPM:5575.0

Remember, this is at the wheels, not at the crank like Mazda uses in their 263 HP, 280 ft-lbs of torque.

Thanks for taking the time to do a comparative dyno! That is one sweet result. You just can't beat that for $310. I'm ordering now...

sheesh.

Thanks all. I just wanted to know myself what my car stands at now, being modded. It has noticeably more pull while accelerating.

If you apply the gains there to the Mazda quoted numbers, you get:

HP: 1.1014*263 = 289.7 HP
Torque: 1.1028*280 = 308.8 ft-lbs

Yes, thanks again for posting. I also have the MS CAI dealer installed when I purchased the car.
