Chris, Ok, I get it now. I've been reasonably polite and tried convey my point. You're obviously just screwing with me. You make one statement and then make a contrary statement right after. You have a complete other thread that contradicts what your saying here. http://www.tacomaworld.com/forum/tec...lters-mpg.html

If you have a question regarding my point, ask, I will try and answer to your satisfaction. However, you can continue on with the regular internet bulletin board crap without me.

I dont see how that contradicts what Im saying? Its about how dirty filters affect mpg, and the post I made says that even when they are pluigged to the point of failure, they dont impact mpg as one would think. Now, what Im gathering from you in this post is, that adding a K&N filter, removing the charcoal filter, and silencer, increases hp. To which I added that a member on here dyno'ed his truck with no filter, and found the gain to be within the margin of error of the dyno, thus being negligable. So, given that the deletion of the filter all together showed virtually no gain, why would a K&N filter give any at all?

I agree with both Chis's on some points each.

I have seen testing done on a Scion tC where they added a TRD "Cold air intake". Made 1 whp improvement. Basically nothing worth the money nor improvement over stock.

I have seen 1GR motors add a TRD and pic up 7-12 whp. Can't remember the torque.

Thus the improvement would be seen to come from not only the flow of the air filter, but also the design of the intake. With out there being a substantial difference between the aftermarket and the stock, there will not be much of a gain to be had.

The motor is going to pull in air. Put your hand, per say, over the throttle body (huge restiction) and you can eventually stop the from a lack of air.

On the extreme other end, remove your hand completely. It will breathe much easier and efficiently. In all actuality that is the purpose of the thottle body disk.

With that in mind, put a very dense perforated material over the throttle body. It will be, inturn, hard again for the motor to breathe. Take it away, and it will breathe freely again. Simple yes.

Now, I know that all of that seems like redundant common sense, but it is still lost to many. My eaisest example, of self, is my turbo kit.

I had a filter on that was from my days with a rear mount setup. That filter would continuously get extremely dirty. Well I had to put it on my front mount so that I could have a filter on, unitl my new one came in.

I had cleaned and cleaned that old filter. Looked good to the eye. But as soon as I did my first test drive with that filter on, versus before with no filter, my truck was immediatly sluggish compared to without a filter. Couldn't breathe well enough, to get the volume of air in fast enough, and thus my boost even came on about 500+ rpms later. Shocked me how badly the performance was with just a filter.

Needless to say, that when my new filter arrived and was installed, the truck got the performance back that was nearly identical to not having a filter on at all.

They do make a difference, but it depends on many things that vary between vehicles.

So, a restriction with a thinner volume of air will have a much greater impact than a similar restricion with a much denser volume of air.

First, let me say that I glad see the thread has not degenerated with all the "discussion".

Chris, Here is a quote from an earlier statement of yours from this thread. I like to present quotes in their entirety, it seems more fitting. But only want to discuss the bold portion.

Quote:
Originally Posted by chris4x4 View Post
What Im saying is, THere isnt any significant restriction in the intake. If the air pressure in your area is 12.5 #'s, then it will be the same in your intake. The "loss in pressure" happens behind the throttle body, as that is the single most restrictive device in the engine. Put a vacuum gauge behind the air filter, do some WOT runs, and see if the gauge even moved. Odds are, it wont. Many people are under the impresion that these engines need 14,0000 cu. ft of air going thru the intake. Think about this.....Your engine has a max CC volume of less than 42 cu. in., or about half the size of a regular drinking cup. The engine needs this amount of air 4 times, every other revolution. The OEM Filter, intake system, sound dampeners, etc., flow this very easilly. If removing, or altering the intake, resonators, or the like, improved the pumping efficiency of the engine to any degree, a very well paid engineer in Erlanger, Kentucky would have figured out how to impliment it into the production vehicle.
If you do not recognize the pressure loss across the intake system, this discussion can go no further.
The other thread has a government study, attached and referenced by you, that measures this pressure loss. They use the data to argue other points though.
In that same thread you say you have seen gains from intake changes.
"The main restriction is still teh (sic) throttle body. Gadget has tested and found the air box to be a restriction. The dyno's I have done have shown no real gains to be had, accept on the TRD and URD intakes.. (sic) And the TRD didnt give a gain anywhere close to what they claimed. IIRC, they claimed 20 hp, and I saw about 5 or 6. Regardless, MPG is affected by the speed at which you drive. A "CAI" only gives a gain at WOT."

Since you mention Gadget, he wrote earlier in this thread;
"On many engines an aftermarket intake can be a waste of money.
I can tell you this I have done extensive dyno testing on the different Toyota trucks and I can tell you for a fact you will pick up power when you get that restictive stock air filter box off of your 1GR engine.
Out of the ones I have tested, the URD makes the most power improvement. On my 2005 XRunner we picked up around 18 RWHP.
The next best of the ones I have tested is the aFe Stage 2si. On my 2006 4Runner we picked up 12 RWHP.
This was using a DynoJet Dyno."

I have to ask, how is it that these intake changes are making power improvements, no matter how significant (or insignificant)?

(too much typing)

Couple of things to add.
I do not sell aftermarket intakes or even own one.
I do not work in the auto industry in any way.
Do not make any decisions based on anonymous internet bulletin information.
I do not advocate modifing your truck in any way from it's production state.
Obey all legal requirements when owning, maintaining, and operating any motor vehicle.
Your mileage may vary.

That was in responce to the messages I have been getting since posting in this thread. Do I have any dyno test results, for web link information, my background, etc.
Even whether Chris4x4 and I are the same person staging this discussion. LOL indeed.
