Intake Pipe Connector Question
 

What is the purpose of the inline cannister looking part between the MAF and the TP? Is it important to keep that on the car or can you eliminate it?
I don't want to do anything to hurt performance. I was considering a flex hose to replace the 90 at the TP and the piece I have will reach to the MAF.
Might look....tacky, I don't know.

It is #17875

Like on most cars I belive it is to keep the intake quite.So it can be removed like most people do. And you don't have a maf you have a afm(air flow meter). Don't use a flex pipe. The idea is to make the air flow as smooth as possible. I would recommend aluminum pipe and silicone connectors. http://www.toyota-supra.info/forums/...picture538.jpg

Good deal and thanks for the picture. Very nice.

It's a helmholtz resonator... it doesn't just quiet the intake, it removes oscillations (turbulence). Removal due to ignorance is not an excuse... if you don't know, look it up... I know, hard to say as there's so much bad info on the net these days.

Figured there was something to it, so what you are saying CRE is that you should not remove it? What will removing it do to performance?

And by the way, this is looking it up for me.:dunno:

I never noticed a problem nor a decrease in preformance or mpg's. With so many people taking them out, wouldn't more people have said something. Unless there is some solid proof to keep it in i'd leave it out.

people are idiots.... I don't claim to be the exception. do some research. there's a great article out there about why Yamaha spends MILLIONS on designing their resonators. ;)

Then why does my 2zzge designed by yamaha run better with the K&N Intake with just a curved open pipe.

It most likely doesn't, you may just be imagining it in most places in the power curve. The resonator is a neutral device in some locations in the curve, like any musical instrument they're tuned for a very specific range... the weak spots.. that's where the most noise is made and as such where performance takes the biggest hit. In some systems this hit is minimal due a more efficient design of the rest of the system, staged throttle bodies and so on. There are also very different types of noise removal devices... some really are only for making things quieter and some do cause a small level of restriction... not the case here.

Here, read through the following link... last time I'm searching info for others. There is a TON of information about this topic by people far more qualified than garage motor heads who half drunkenly assume that added noise = more power.

K&N makes VERY poor filters by the way (this too is available on the net ;))... let's also cut to the chase on a couple other things while we're at it: larger diameter intake AND exhaust piping are not always a good idea (ESPECIALLY on a N/A); and a larger air filter that's sitting in a hot engine bay, sucking up air that's 20 degrees or more above the outside air temp causes BIG losses in power. You don't see a huge change in mileage because you're actually getting LESS air.


I'm done. Find your answers and think what you like it's obvious I'm not going to convince you and you're definitely not convincing me.

Cre,
I thought that asking questions and discussing possibilities was one of the benefits of a forum. I did some research but since I consider this site a research spot. I don't mind looking around for answers but what I found here was a concentrated source of info. I am new but without this forum I would have struggled much more. I don't adhere to every opinion posted, it is my responsibility to determine if the info I get is usable. The value of what each person has to say can be supported or dismissed all on the same page.
You have a huge impact on the site when it comes to solid tech help. I appreciate it. If this has become a burden or thorn in your flesh, I get it. I have similar experiences in the motorcycle industry, stupid people are out there.

If I am using the forum incorrectly I would prefer you tell me.

No dlfred, it's not you....Just really feels like lately right after someone asks a question everyone sticks their fingering in their ears. I deal with with enough of this at work that I guess I'm expending the sum of my patience there. I'm sorry about that. I'm really not trying to attack anyone, just getting grumpy about the whole "but, but, but" replies with no supporting info ever posted instead (not that that would have made any difference, I too had my fingers in my ears). I definitely shouldn't have started complaining about people not searching for the right info right away... that was a knee-jerk reaction.

I don't think any losses experienced from removing this are considerable, but I can't be sure, mine is the only N/A I've ever removed it from but the intake was already significantly modified due to the removal of the VAFM. Personally, I feel the 7M-GE is a platform which was merely *pretty good* for its time; which left the factory putting down pretty close to it's limits. I've seen enough people prove that you can't gain even 10HP with any simple mod and others prove through their own disappointment that by dumping more than a few thousand dollars into the engine you'll still end up putting down under 300HP at the wheels.... so, do whatever it takes to make you like it, just don't do it for power gains and don't believe anyone who tells you these "free power adders" actually work... they don't.

Synopsis: I AM grumpy and bitter. Resonators are not always just an audible noise control. Ar filters open in the engine bay = BAD. Big after market parts manufacturers make and sell what people buy, not always what actually performs. And I need to take a vacation.

My answer to the open filter in a hot engine bay. Atleast a start for now. And I don't know why the K&Ns get so much heat because the TRD filter I took out of my Celica seems to be made of the same wire mesh and cotton filter material.

Just because Toyota licenses the TRD name out for a product (no, Toyota doesn't actually make any TRD parts) it doesn't mean it's good for anything.

Boxed like that you're alright. A fully enclosed and insulated box would be even better but that's miles above what most people run and not "open" like i was talking about.

CRE.

You know what, I should apologize as well. I have been working with the retail public for over 30 years. This should be a place we can do some venting and/ or ranting and get away with it. As usual if I had thought my post through it may have sounded different.

Your posts speak for themselves, thanks dude.

I found a elbow and union seals that should work from Auto Zone. That will allow me to keep the rest of the intake original. I finally got to the twisty's in the mountains of NE Georgia today and now the suspension thread search begins.

I still have not found a good intake elbow other than oem. The Pep Boys hose was not the right size. I have been searching and cannot seem to locate anything. I have a NA and most of what I find is for the turbo model.

if it fits, it fits man. i mean if you're gonna take that piece off after all

It is totally my fault CRE is grumpy lately, my bad, and I apologize CRE. Some of the K&N (not mk3 supra) kits come with a heat shield to block off the engine bay from the air filter. I have been wanting to make something for mine that would do that but never got around to it, and there is not much room to do so... I seen on K&N reviews that they do not block as much dirt as they should. I put a pantie hose over mine to keep bugs and excessive junk out of it, and it works good. Same thing as an K&N Outer Ware only $59 cheaper...

should be a post in one of the faq's that list a few different air filters that were thoroughly tested w/ posted data results.. apexi rated one of the highest.
