and anyways, you guys sound childish and stubborn when you think too hard and start excuses like the world didnt move fast enough at that moment so the dyno didnt properly record the HP...

.i know there are variables on dyno's (temp,pressure, and air) but cmon dont be so stubborn, IM TELLING YOU THIS THING IS A PIECE OF SHIT, HE LOST HP NO REASON TO ARGUE FURTHER!

You really don't understand dynos at all, do you? two dynos of the exact same make, fed the exact same variables, will read two different HP and TQ numbers. Dynos are NOT an exact tool, that's why you have to do a baseline on the dyno you are going to be using, then make the mods, then make another run on that dyno, not on some other dyno.

Also, cars DO NOT make exact HP numbers. Engines, transmissions and drivetrains are built within specs, and if you happen to get one that everything was built at the loose end of spec, and compare it to one that was built at the tight end of spec they will make different power to the wheels.

If you were to take 3 identical 325s and run them on a dyno you'd get 3 different numbers... then if you were to take those 3 cars and run them on 10 different dynos you'd probably end up with 30 differnet HP numbers... hopefully the varience between cars would be the same on each dyno, but that's not even guaranteed.

= childish and stubborn.

Until he runs his car on the same dyno with and without the intake, and with NO other changes then nothing has been proven.

IT IS TRASH

Like I said before, I'm not saying there isn't an issue with the intake. What I am saying is that it is now impossible to see what the true difference is because the condition of the car has changed from one dyno to the next.
NO ITS NOT IRRELEVANT. If there had been a difference of 20 hp, we know that the gain could not have come from just the catback, so we would know the stock intake would have played a part in the hp improvement. Thats why I said SIGNIFICANT. Of course we can't see exactly how much hp was lost due to the Fujita, but if there had been a significant difference we would at least know that the intake caused a hp loss(which is all that really matters in this discussion).

I think getting raped by a stock 325 is enough proof for any reasonable person.

you are wasting your breath honestly, all this was taken into consideration when i wrote that post, i am aware of how innacurate a dyno can actually be. Although you HAVE proved to be somewhat intelligent, its of no concern to me . you have graduated highschool my friend. congratulations.
As far as me being "childish" and stubborn" i would disagree. More like "restless" and "aggravated" with some of the people who post just to hear(or in this case see) themselves talk.

This is so funny for a technical thread...I did not know fajita is in so much demand by e90 car. Dude, you want fajita, come to texas, there are plenty of it here and they are cheap.

buy one get one free. Can I supersized a fajita?

I have came to a conclusion about intakes ( i have owned about 6 intake for all my other cars)..wheather its fujita, k&n or any other intakes is that intakes and power dont really go hand in hand.. because the power gain from these things is sooo small that if people get intake hoping for big power gains is impossible. Whether the fujita is a POS is basically an opinion of everyone. I could say that it is great and other people can say is sux but if people were hoping more power people should look in other places than intakes. Now if there was a loss of power that that would be a diffrent story..
just my 2 cents

Why I bought intakes for my previous cars:

1. Look
2. Sound
3. There is no #3
