I defend a guy that was thrown an insult, sure maybe with some pointed tone to my comments, but really...
I point out that others have stated that there isn't any real benefit to it, and just link 1 single discussion about it. Hell, I even say that I would bet that with some real testing equipment that YES you could probably measure some level of benefit, but in practice, you aren't going to notice enough benefit to warrant the amount of cleaning of the filter.
So you stated the exact facts that I said probably existed, but felt that a personal insult was due.
I know that some people are looking for every fraction of HP or toque boost that they can get. To them, enjoy cleaning your filters. The amount of dirt on the filter for a FWI after a mount seems like it would certainly negate any amount of performance boost (pun intended) that you would get with the fractionally cooler air after going through the supercharger. I mean damn, there is more to it than just air temp. There is also the amount of air allowed through the intake and into the TB. Breathing with your mouth open while jogging on a hot day beats out sucking air through a straw on a cool one. So none of the tests take into account real-world use and maintenance. They are done with new/clean filters. What about a test after a month of use? That would be helpful. Again, not discounting your data, just saying that for ALL of our benefit, there should be more information since most people don't clear their intake filters nearly enough, and that is even when they aren't crammed down a fenderwell.
Again, you stated the exact level of data that I said would be measurable and available. You made statistical points which are appreciated, but my statements are still true and valid. You make one single point above. HAIs reduce timing. Sure does. Is it noticeable to probably 99% of the population, probably not. That was my point when I said "it really doesn't make any noticeable difference" and "Sure, maybe with some testing equipment the FWI may give an 1/8 HP of improved performance, but that is about it. It certainly felt the exact same, and then I didn't have to clean the darn filter so stinking much."
So for those that want the hard data, look at my link above and 91parkave's data as well, and basically just decide if cleaning the filter is worth it to you since you will have to dig it out from the fender every time. If it is, then go for it. If not, you have hard data and real world usage and maintenance information at your fingertips now.
YOU make the decision. Do your research based off of your needs like I did and factor in the dirt factor into your maintenance schedule and how it will impact the slight increase in performance (detectable pretty much just using testing tools) and make up your own mind. Feel free to come back to this thread and post your findings. Just be aware that others may call your dumb, or an idiot, or say that you have no clue about it when in fact in ACTUAL USE, the difference was not noticeable to a human being for a lightly modded 00-03 series GTP. Your mileage may vary.
Good luck sports fans.
