i heard the k&n filter actually makes you lose 2-3 hp over stock filter now would the holley powershot make you lose hp over stock air filter? i heard i should get a hi flow air filter with my slp lid and ssra, which filter should i get that wouldnt make me lose any power at all? i know its only a few but i dont wanna lose any lol

 

A paper filter is cheap insurance, I'd stay with that if I were you unless you like to say you've got a K & N.

I've heard people say the K & N needs to be dirty to flow air better and doesn't flow air better when it's clean. I do not understand that at all.

 

eh, the Holly and K&N supposedly only flow a little bit better than a paperfilter. I real advantage to them is that they are reusable. Personally, i have a Holly in my car, it gets cleaned everyonce in a while. I guess i still have it cause i dont' like saying i have all this other crap and then there's my paper filter (most won't understand). Only difference i've heard between the two is that the K&N doesn't fit as well and needs a gasket to seal the lid correctly. When you clean em, the biggest thing is to make sure you don't over oil the filter. The MAF sensor goes wiggy when there is oil all over it.

 

Actually they flow better clean but filter better the dirtier they get.

2-3 hp is nothing that you'd ever feel or miss. Get a filter to filter. Its that simple. An air filter is NOT a performance mod.

 

 

i agree a filter itself is not a [erformance mod, i also agree i wouldnt miss 2-3 hp but if you add each mnod up and say just get the cheap one you will only lose 2-3 hp , you wont notice, well do that with 4 mods and your talking about 8-12 hp, alot different lol

 

Can you guys explain why you'd lose HP with a K&N and whatever else? I thought I had it figured out why it was BETTER than a regular paper element...help a brotha out?

 

Very simple.

The better something filters the more restrictive it will be and the more something flow the less it will filter.

Ya, the 2-3 hp will add up over several mods, but its a friggin air filter! Its designed to do what? Filter air. Get a stainless mesh filter and gain even more power over the paper filter, but when your car is blowing blue smoke and mine isn't, I'll still take the 2-3 hp loss. To me the object of an air filter is to protect the engine.

I wouldn't consider the K&N as the "cheap" option either.

 

ok... here is what I have so far..

panel vs panel = paper over cotton gauze, paper will not filter as good but will flow more...


Panel vs cone = cone filters increase the surface area therefore while they are more restrictive they will still allow more total air in..

I have spoken to some ferrari guys that have done some tests and found to get over 10rwhp with just their swap from panel to cone..

LT1 guys also see this.. but this also stems from the fact that its just not a filter change but an intake system change...

I personally enjoy showing people my paper filter because its more impressive to even those who dont know better to be fast and still on paper..

 

Hey psychocabbage how many times have you answered this question in the past month? I plan on going to the track this weekend and getting some back to back comparisons of my own.

 

See....you are going by the logic...if it filters more, it must have smaller 'holes' am I right? I'm not in anyway saying you are all wrong since, apparently, you guys have tested it. But I thought it was cotton had bigger 'holes' which flowed more air, but flitered less. Thats where the oil comes in, not only makin the filter look pretty, it had an opposing charge to the dirt running through it, therefore 'sucking' dirt away. Thats what I thought it was...apparently I was wrong? I dno...o well....

 

He's done dyno tests comparing paper cotton oiled and no filter and found the paper to give the most power.

 

I have no idea.. .but I didnt want to be "paged" again.. hehe
Cant have everyone thinking I am slacking... I plan on doing a couple more tests.. I keep over thinking but feel that it will help lead to no more wasted thought on the matter..


My variables are the learning computer.. Does it learn over time or can it read off of the MAF and instantly be "tuned".. I am leaning towards the second scenario just because the MAF is such a finicky thing that it can make and kill power at will or so it seems..

My next test will include me driving around with an aftermarket filter for 1 week (doing deliveries and usual driving) then getting to a dyno and doing the tests all over again to see what the dyno says.. IF it shows the same exact data yet again, then I will stand behind my numbers forever.. if not.. then the "learning" of the computer would be something that would have to be taken into account on every dyno test of every product.


I am trying to get a new driver hired so I can get out of the restaurant here and there..
