Exhaust+CAI=Results? I've got an opinion.

Alot of butthurt in this thread ,

 

Drive it like you stole it, in gain range 100% of the time.

 

Haha Christian, we're old.

 

Well I wasn't going to say anything... but since you brought it up..

 

LOL.

 

My God man! I remember when I first rode my buddy's R1. I couldn't believe those engines didn't redline until like 13000 RPM. Even Dodge Vipers redline at like 8500. But this guy has his Tacoma motor so well balanced and polished that he can rev in excess of 45000 RPMs. I'm impressed. That's like 8 times the stock redline.

 

No, but I just bought a lifetime supply of Ensure. Figured I might as well start drinking it now...

 

Whipper you've got a great amount of perseverance. I never got "butt hurt" lol obviously there are things I am not deeply knowledged in. I honestly don't care and haven't ever since you opened your mouth. I like my parts they are fun. I mean let's think about this, I don't even know you so I really could care less about what you have to say. Sure your knowledge is greater when it comes to trucks but everybody has their preference of knowledge. I hope you and your Taco enjoy hundreds of thousands of miles together I'm going to enjoy mine.

 

That's what I said I was gonna do

 

But if I breath through a garbage can I'll still get 1-3 MPG better right?

 

Yet when actual tests are done using EPA fuel test cycles that are extremely accurate at measuring differences in fuel use they find zero improvement with free flowing vs clogged intakes for mpg.

Did the same for the same reason and would do it again.

 

OP. Too many people on Tacomaworld disregard improvements, unless they are for off road. Lol. Filters don't increase or decrease flow or MPG. Despite the fact that there is recorded proofs of difference. Whether by individuals of established facilities.

If you really want to get to the bottom of it for yourself, you have to do something extreme. Far spectrum say between clean and dirty.

I know for a fact that the filter on my car has been proven to make the boost threshold on my truck delay over 500 rpms. Also, tested on a car it has caused a loss in two mpg. (That was from stock, to the filter, then to a new filter of the same kind, but clean and it picked up a back up the mpg lost but the car was able to accelerate more quickly after the new filter. ) < So it didn't actually gain any mpg over stock, but was per drivers words able accelerate faster, which means a gain in hp.

And alas, it is now on my car. I have noticed a two MPG loss as well. But until I get a new filter to replace it, it will have to do, as the factory stuff was falling apart misserably.

The point is, that this particular filter had become so dirty and clogged, while it was used for my rear mount tuebo kit, despite three or four cleanings, it still does not flow well enough to allow easy of breathing for the engines. Whether boosted or not. There is a definite flow restriction. Compare it to breathing through a pillow, versus a sheet. The same physics still apply. It's a fucking clogged filter. It can't flow well.

That would be on the far opposite end from clean and free flowing. Versus a test of something nominally dirty.

Funny thing about that whole air filter spill, is that you never see someone debate anything about the differences between a free flowing fuel filter and one that is not free flowing. Whether it be clogged, to fine micron filtration, or what not. Although the same principles apply there.

So. Either take off your intake/exhaust and then do before and after dynos, or look up Southwest Research out of San Antonio, and get lost in all of their amazing data for cars and trucks of all makes and models.

 

There is a simple saying that would best describe this in ohms law. "energy will follow the path of least resistance." This saying is true for many, many things. If there is a restriction point (in this case clean vs dirty not filter materiel) , it is harder to overcome. Simple fact.

 

Path of least resistance isn't part of ohm's law.

But in the case of mpg, the path of most resistence is the restriction through the throttle plate, not the air filter.
