we'll see then. so i'm not saying that everyone should start writing letters or rip theirs out.....yet
, i'm just trying to be as exact in this as possible & account for every little thing & provide completely accurate results for you guys to decifer & pass your own judgement on Ruckus46Gt said:ok ready....maybe you have some freak car that doesnt respond to a dyno. If what you are saying is true then the people at k&n, pro 5.0 mag, muscle mustangs and every other person who has done research on the gains were wrong. It must have been some godly given hp after the switch happened and they dynoed it. These new cars have computers. They need to adjust to some things and changing your air filter requires the computer to adjust because you are sending more air in. When you did your dyno's did you think about check if your car was running um lets say lean or rich or anything? It probely didnt adjust to the filter and then you took it out after a short while and put the stock in which it was used to so the numbers look better
Ruckus46Gt said:anyone else see that the story keeps on changing?
the numbers are there in back & white, you can believe it or not. it makes no difference to me. so just go back & bury your head in the ground & not listen to anything & believe the earth is flat
NasaGT said:Well, if you are going to dyno again, how about starting with stock filter and then switching to K&N?
that's actually what i planned on doing. i didn't bother to re-install the k&n since it lost hp, pretty handily. so i will do it in that order next week forpit2000gt said:I have seen a care make no changes and make three pulls that were + and -5 hp of the baseline pull. Same day , same car , no changes, all within 45 minutes. Why did this happen???
K&N filters ahve proven to flow better than stock and that is good enough for me. Are you saying easier flow will cut HP? maybe I should stick a sock in the TB to give me more tq and HP.![]()

You have to add length to the intake. That means you have to buy an intake and put your filter in the fenderwell. Go buy an intake and do the same tests, and those results will be different.
but if you put the filter in the fenderwell with a intake & a 90 degree bend like most, then it makes you run on the rich side. not that this has anything to do with what we are talking about, or am i missing something

You have another guy saying you should clean it and re-appling the K&N juice. It is a brand new filter, right out of a brand new box, right off the shelf, why should it need to be cleaned and oiled to perform as advertised
