    How affective is changing intake temperatures?

    My question is,

    How helpful is a large decrease in intake air temperature?

    And also what affects does cooler air have on your performance?

    Also what else does cooler intake temperature help?

    Basically what I am asking is. Say you have a stock intake box. than you switch to a cold air. Which sucks are from outside of the engine bay more efficiently than a OEM box. How great of a affect does this have one you Engine?

    I have searched this and I have a good understanding of what im going to be doing but I would like some more insight on this topic.

    I already have a short ram on my car. I am not searching for the reason of buying one. Just general research for my knowledge.

    I thank anyone that gives useful insight/knowledge ahead of time
    Thank you,
    Steve (bucky)

    Cold air is more dense, therefore it increases hp. I've read that for every 10 degrees you drop the intake temp, you gain roughly 1 hp

      Ten to one is average, I believe. Humidity and altitude also play a part. If you watch guys at the track, you'll see them putting bags of ice on their intakes and top mount intercoolers right up until they're next.

        its a fight

        some say,
        too cold is bad, too heat is worse

        heatwrap header, plastic CAI, coolant bypass, lower t-stat vent hood will proably drop a few degrees

        removing the t-stat is not an option

          Yeah im working on this project and I know the tubing I have designed and made will definitely decrease temperatures. But the problem comes with the filter part. No matter what it's going to be a fight to get that to stop grabbing hot air.

            cai is probably the best way. Or if you run your ac all the tim run a intake tube into your car LOL super cold air!
            What makes me laugh about forums, is that no matter how much you try to help someone, they dont take the advice. Go ahead and do it the hard way.

            You got to respect what you drive, and appreciate what you have, making the best of what you got. and if that means putting CAI, HID's, a phat stereo system, and a idiot in the drivers seat...then so be it!

              I believe I remember reading something similar to this. I think they somehow ran a some duct work from like an ac vent to the intake tube for colder air.

                I did a study in my van with and without a CAI setup. The temps were lower but not that much lower than engine bay temperature area.

                but its better than nothing, I didnt have any airflow going into the area inside the bumper so thats probably what would help

                  Well for a project I am working on a intake tube that will reduce air temperature. But it will be very minuscule compared to what it will be once I figure out a way to actually have it drawing in cooler air

                      I also remember reading in a magazine back in the day, this guy did a test on intake tubes. He had one he spent a couple hundred dollars on, I believe it was an AEM, did some runs at the track, then he had one that he spent a total of less than 5 dollars on, it consisted of some PVC pipe and a 2 liter Mt. Dew bottle, the one that was less than 5 dollars showed more gains than the expensive one
