I think he's trying to mention air velocity as compared to ????.

I really can't make out what he means.... other than its absolute...

See, I told chews is that the Squeak key comes clean with the basics. Say, I draw through a Marlboro and that has a filter. Say I suck on a Camel, how much draw in velocity will one exceed more than the other?

OK, In engine RT (reaction time), how much faster did the engine spin with a filter or without a filter is do not ask the slur pee machine.

i think that he's asking if the engine will rev faster with no filter V. paper filter V. k&n filter. i think...

I read somewhere that k&n filters do flow but at the expence of filtering, they don't filter as well as others? I personally use accel cool blue filters.

That's the myth behind it. As per the example I showed. If it can allow so much air flow, then what else is getting through?

I believe the Kool Blue filters are the same oil-soaked cotton gauze concept.

They increase air flow at the sacrifice of retention. There are a number of ways to increase retention, they decided to use oil as a media to trap particles flowing through to increase retention value.

Is it as good as a stock paper filter? I dunno, i'd have to test on my equipment. (which is not possible due to the oil used contaminating my equipment)

and if you read somewhere in the K&N filter instructions it says it filters better the more dust. dirt and crap has been sucked into it.

My question is, what size particles are allowable? Is it worth the extra protection that the paper filters offer, or are the smaller particles trapped in the oil or blown out with the exhaust at no mechanical cost?

Also, I have one of Summit's cotton gauze conical filters and it doesn't require a filter oil. Is there a difference in its filter media, or is it just letting all sorts of crap through?

Think creole and skip every other word and you can almost understand him.

Which is the reason I'm not fascinated with them. I don't like getting oil on the maf.

Preferably nothing is really allowable, but that won't happen. The filters I design and test filter down to 1 micron (sometimes smaller), and depending on the customer, we are allowed 1 particle to pass for every BILLION particles thrown at the filter.

I seriously doubt engine manufacturers are that strict, but i don't know what is too big for an engine. I would assume huge ass partciles and sand and small birds are what you'd want to keep out, but tiny dust particles more than likely will flow into the engine and out harmlessly. In fact, most particles that small would more than likely be harmless.

I don't know this for a fact, so don't quote me on it. I know my specs i need to meet for my filters, and i would love to do a paper filter vs K&N retention test comparison. I can measure the number of particles that gets through AND tell you what size they are....however..i can't do it unfortunately.

Why don't you test a K&N without filter oil on it? It would be a worst-case-scenario thing.

I just can't. It's not worth the risk.
