Ok so I have been debating whether to use a CAI or SRI. People say that CAI's draw in "cooler" air from the outside which means more HP. Other people say that while the car is in motion air will go into the engine bay and the SRI will still get cool air. I have never seen a test showing that this is true. So I thought I would do this test myself. I am going to be measuring the air temps while the car is in motion with one of my alarm clocks. Yes my alarm clock. The alarm clock runs on batteries and came with a remote temperature sensor. (pictured below)
The remote has a 6ft wire and at the end of the wire is a sensor that measures the temp. The remote then sends the temp to my alarm clock. To check the accuracy I placed the remote on a shelf and placed the sensor next to our thermostat for an hour. In the pictures below you can see that the remote is pretty accurate, The thermostat read 70 deg and the remote read 69.8 deg. I then went back to my room and checked the clock and it showed 69.8 deg.
I'm going to do the test in the afternoon on Friday when I go to my brothers house in Indio. I will only do the test on the freeway since there will always be constant air. According to mapquest the freeway mileage is 77.2 miles. So for 38.6 miles I will measure the temp of where the CAI filter will be and for the other 38.6 miles I will move the sensor and measure the air temp where the SRI would be. I will take 4 measurements for each area. 1 every 9.65 miles, then get the avg temp. To keep the sensor from moving I will wrap the wire around a piece of wire hanger and then secure the wire hanger to my SRI and place the sensor in the area to be measured. Of course there are better and more accurate ways to test the temps but I can't test those ways. This is just to give an idea if there are differences of the temps of were the filters are while the car is in motion. Now I just have to decide where to place the sensor to measure the temp for the area of the SRI filter so please vote above. I will place the sensor in the area with the most votes.
If you have any suggestions please post them and I will see what I can do.
