Airaid test data

[ChevyHighPerformance]

I decided to run a little temperature test on the Airaid air box and stock (with airaid filter)

H3 mileage - ~150 miles
outside temperature 77 F
Course was about 7 miles long and the air inlet temperature (via the PCM) was measured at two points at the end of the course.

Test 1 - Airaid

max temp after red light - 118 F (hot underhood air was being sucked in)

Point A - 108 F
Point B - 100 F

Followed by idle in driveway for:

2 minutes - 120 F
3 minutes - 124 F
4 minutes 126 F

Test 2 - Airaid filter and stock air box lid

max temp after red light - 108 F

Point A - 90 F
Point B 88 F

Followed by idle in driveway for:

2 minutes - 102 F
3 minutes - 108 F
4 minutes 115 F

I didn't do any 0 - 60 MPH or dyno pulls - the mileage is too low.

Even though the Airaid breathes better, it sucks in warmer air. Every 10 F increase in air temp results in about a 1% loss in HP. I don't know if there is a net gain with the Airaid (the throttle response did feel better with the Airaid) or the impact of the warmer air on fuel economy.
