K&N Oil Filter - Performance Gold?

[bobchris]

I read the test method! ??
I would say K & N pays its Marketing and Advertisment personnel more that it engineers.
Its makes perfect since while making no sense.
Typical Marketing BS

I would say you need to go back to reading class. Obviously you've never done any engineering that requires documentation of standardized testing methods that are universally accepted in the engineering design field.

Now bob lets be civil… It’s all in the interest of knowledge here.
I have done a little engineering, but not much, just 5 days a week for the last 30 years :-)
You missed my point. The K & N link is a detailed description of how there filters are tested; it makes neither comparisons nor states facts that prove it will increase HP over a flame arrestor. That is what this thread is about.

[bobchris]

Well if you don't understand that more air in equals more power out then you flunked engines 101.


And if you don't understand that a flame arrestor, as presently designed, cannot redirect air flow or create less turbulance like a K&N filter does then your not going to get it either.

All you need is your flame arrestor, a K&N flame arrestor, a vaccum, a clear tube, some string and a plastic object and some duct tape then you can build your own test rig and prove it to your bonehead self that the K&N arrestor flows more air

do you really think that a filter company wouldn't sued them for false advertizing by now if it wasn't true or are you really that thick headed to think that after twenty some odd years they have been lieing all this time and no one has challenged their claims please get a clue.

I didn’t read that anywhere on that link but OK! I will take your word on it.

If K & N says their filter is better than a flame arrestor it must be true. I mean they wouldn’t say that just to make money would they?

you call yourself an engineer and you cannot even figure out how to build and test such a simple rig to measue airflow.

Again spend a little more time reading the info on the site the info has been around for years. But again if your not very versed on airflow and how to redirect or create less turbulance then you will never get it.

bob im not a last word freak so I will let this thread die.

I think I'll end what I have started here. First of all, this thread was originally about oil filter brands.....whoopdy doo. I threw a pic in of my old boat that had one and a KN Xtreme flow top. Some of you knuckleheads know whats really up and some of you don't, i personally don't give a **** what you think.

When I originally installed the KN filter on my carb, I ran the boat 0 to top end around 10 times to get the feel of how much acceleration was there without any filter or arrestor. So then I installed the KN filter and started another hole shot or two to max speed, and I can HONESTLY tell you there is a big difference. Believe me or not, I could care less, because I know for a fact that it made an improvement. I don't need a dyno test or a stat test to prove that. I am by no means implying that it is safe to use one.

I can't believe all the haters on this thread who live and die by the numbers. You guys are pathetic. Back when I used to race RX7's, I loved beating idiots like you who needed a spreadsheet to tell them there car was fast.

Wow this one did take a bad turn. There was no intention of ruffling feathers. I personally feel (and a public forum is a place to give opinions) that K&N is a bunch of hype. If you want to use a good flowing filter then use a AEM or AFE. They are much better built and have 7 layers of media instead of 4. Lets not go to name calling. I think that we come here because we love these boats and try to help each other when we have issues. Just don't be suprised when there are differing opinions.

Actually, you dont know "for a fact" that it helped- since you dont have a shred of evidence to support your claim, all youve got is an opinion... and its one thats not supported by any logic whatsoever.

In case you hadnt noticed, there is a lot of BS floating around on the internet. Its not always easy to catch- but these numbers that some of us "live and die by" might be a little helpful in backing up (or disproving) your claim. GPS numbers, a scientific test of some sort, dyno results, or at the very least instant holeshot RPM's, etc might shed some light. Oh wait, you said it HONESTLY made a difference- nevermind, I believe you then. Yellow_Flash_Colorz:

[SuperSquirt]

I told myself I was going to quit lashing out and name calling, but you guys are cracking me up.

TRBenj, you're right about a lot of BS floating around the internet, and I am the first one to admit that I don't believe everything i hear. I can tell you're very biased and probably very old too, but if you want some proof, go out and buy a 9" or even an 11" xtreme top and hook it up to your 78' Ski Tique. Now I know its a little too much bling for that boat, and you might want to call your insurance agent before you do, but your 450 Holley will cry mercy when you start shoving 700 cfm down her throat.

Please leave the ugly comments out until you do. Thank you and have a wonderful holiday :razz:

if you think k&n is hype why have they been around so long why is it the upgrade of choice for air flow, why does it work well? if you're worried about the original $5 extra then you dont own a nautique. aem makes ok stuff. it's all relative. if you're so intrigued email one or both of the companies and tell them youd like a performance test sheet to see what's really going on. if you havent noticed by now oem stuff is not always the best. nor is aftermarket, but k&n is like a mexican. it works

[AirTool]

...., but your 450 Holley will cry mercy when you start shoving 700 cfm down her throat.

Yeah, at 6892.3 rpm if it's a 351.

Or higher, since his volumetric efficiency isn't perfect. Lets just call it 10,000.

I think winter is starting to take its toll on everyone. I think everyone needs a dose of warm sunshine.

[8122pbrainard]

Maybe someone can provide me a link to the K&N site where it shows the comparison specs between a USGC flame arrestor and one of their products. I sure can't find it!!

And the original question was????? Oh yeah, oil filters....
