    dyno PROOF on k&n filters....... part 2

    well here's the "proof" for you guys that were pitching a fit in my other thread. it's all in black in white, done on the same day, under the same circumstances, so believe it or not, here it is :D & by the way i can post dyno sheets if you like, but i will have to email them to someone else & have them post them :nice:

    btw -- this was done on a mustang dyno, so pay attention to gains & losses & not the actual numbers. mustang dynos read lower than dynojets, so there is nothing wrong with my car.

    please note .......car is in stock form aside from removed silencer :nice:

    here were the weather conditions.......temperature -- 63 F
    barometer -- 30.3 (104)
    humidity -- 48%

    run #1) WITH k&n -- 208.8 hp @ 5250
    244.1 tq @ 4250

    run #2) WITH k&n -- 210.7 hp @ 4750
    244.1 tq @ 4250

    run #3) STOCK -- 215.5 hp @ 4750
    246.9 tq @ 4250

    run #4) STOCK -- 217.6 hp @ 4750
    247.9 tq @ 4250

    Here are the averages...... WITH k&N -- 209.75 hp & 244.1 tq
    W/O k&n -- 216.5 hp & 247.4 tq

    There WAS a LOSS of .......6.6 hp & 3.3 tq


    so with all of that out of the way..... if you don't believe it i could care less, it's there in black & white. don't get all ****ed at me cause you possibly wasted 55 - 60 bucks just like me. also the reason i sad "possibly" is i will also do a test between the 2 air filters again next week, after my exhaust is installed, to see if the K&N gains power after my exhaust is much less restricted.
    so if you don't believe this, i doubt i could convince you the sky is blue :rolleyes:


    also....... ALL RUNS WERE DONE AT OPERATING TEMPERATURE, THERE WAS NO WARMING UP, or cooling down during the test, i put that in there because i noticed that the power just kept going up :D

    so there you all go....enjoy :D

    oh yeah, one more thing..... when we took the k&n out for the last two runs we forgot to plug the mass air back in :nonono: :bang: , so there might have been more in there somwhere :shrug: i know it wouldn't make that much of a difference, since it doesn't do that much under wide open throttle. but every little bit helps. i didn't find out unitl i got off the dyno & "tried" to drive away :rlaugh: :bang:

    LMAO@ this guy.

    Of course you will have more power without a filter. Now put in the stock filter and see what happens.

    I didn't read the last half of the other thread. The post-hoes started going crazy and I skipped it, and then it got locked. So I didn't know he was going to dyno again (hence my question above) and his original post made no mention of using the stock filter. Why not call those runs w/stock instead of w/o K&N? It would have been clear that way.

    Anyhow, back on subject - those numbers are shocking if true. Since the power just kept going up, I wonder what two more runs at the end with the K&N back on would have produced?

    Please edit your original post to make 100% clear that you tested the K&N vs. the stock paper filter. I thought you may have run with no filter also.


    Now this is getting very interesting.....
