okay sorry my bad. honestly, i thought the outside temp made a differance.  cars are confusing  |
Of course cars make more power with cooler air, but we just calculated that the heat sheild you rigged up is only good for 1 to 2 degrees of cooler air, which when considering the variances inherrent in power output not related to air temperature, isn't enough of a temperature drop to make a useful difference versus a car without the heat shield.
Like I said, I agree that on paper you can calculate the benefit of the mod, but in real life, it's not going to do anything aside from giving you a warm fuzzy feeling that your intake is colder than it used to be.
Now, if we were talking about a normally aspirated car w/o an intercooler, this would be a totally different argument. I just don't think that the benefit on a stock STI is measurable. You're certainly not going to win a race because you added a heat shield to the intake, and that's really the only measuring stick that counts IMO.
