wow, good to have someone else so knowledgeable on board

Vortex MAF sensors sound quite complicated, but it does sound like they will not slowly get less accurate over time.

Keep us posted on progress!

Parted out Scion xA intake: $35 overnighted via FedEX
"Ugly Betty" ghettotake: $65 on Visa debit card
Seeing Baskin post on a Yaris forum: Priceless.

There are some things in the world Hitler would find funny.
This is one of them.

Bump for interest!!!

Betty 2.0 begins tonight! We've got pipe, plate and a coupler for the TB!

Chino... How much will it be?

[FR] Sébastien Loeb · 03-08-2007, 02:44 PM

when buliding an intake with many pieces and tubes combain together, the air flow will not flow as free as an intake that is build with just one or two tubes together such as most of the aftermarket intake kits ( TRD, AEM, ect...) therefore you are better off getting an aftermarket intake kit to get the most air flow out of it.

Lets just say in a group buy situation you're looking at about 80-100 bucks shipped with no filters... maybe even less if we can get 15 or 20 people in on it. We still haven't sourced all necessary parts, so it'll be a few days before we know for sure...

Shut your face Loeb!

No, you're right... the smoother the pipe, the better the flow. However, the finished version will have two couplers, and only one will be funtional in air flow... two pipes, one with the MAF adapter, and two couplers, one for the throttle body and one for the 2" to 3" flare... other than that, straight aluminized steel pipe. I told you... that was just the mockup! If you want to spend 150 extra bucks (at least) to avoid one little coupler, be my guest! But please, spare me a lecture on the basics.

jdubau55 · 03-08-2007, 04:27 PM

Its all on how you pieced it together. As long as the "steps" were placed right. Say the first connection in inside and the second outside. Then the air never encounters a "lip" to flow over.

Even with the connection from In to Out, the air flow still does not flow as free as a one piece pipe, also the In to Out connection limits the air flow due to the tube being narrow down more and more as you connect it from In to Out.

CASTREX · 03-09-2007, 11:09 AM

Is Chino making an intake for a Ferrari or something?

Mr. Loeb is totally right guys! With all those parts you will be loosing maybe 10%-15% of the power that a fancy intake can give you due to flow inefficiency.

Supposing a 4-5 hp gain, a 15% loss will be 0.6 - 0.75 hp.

So..... 0.75 hp Vs. $150 saving. What do you think???

Good luck with your business Chino!

Too bad I already have one of the fancy intakes... otherwise I will be sending you my cash for sure.

Thanks for the kind words CASTREX.

If it makes you guys feel any better, I finally have my appointment at the dyno this Sunday. The regional Mustang Dyno tech is coming in to make sure this time around our readings are accurate. I am not even going to bother dynoing the Megan header again. The goal is by Sunday we want to have the production prototype finished and on the car so we can get accurate readings. The mockup that is on there now would read out at a tad less power due to the 1/4" wall sitting in the piping right now. I'll take lots of pictures.

blake111887 · 03-09-2007, 01:16 PM

cool, hope the dyno testing goes well, i still think that when you have the product all finished and done with its going to be something to brag about, i mean tlike you said this is a mock up product not the real deal so if you get the project on the way then i think that this will be a performance part a lot of yaris owners will want to have.

ChinoCharles · 03-09-2007, 01:33 PM

I have a LOT of help. I can't weld, CNC machine, use a drill press... I'm wrenchtarded. You guys saw how well the header install went.

There are a lot of people here involved in this project... you'd be amazed how the old-school tuners light up when you tell them you want to put spray in a 1.5 L econobox, or when you tell them you have a working prototype of a possible production intake. Even Chris... he's all the way in New Jersey but I couldn't have done this without him.

Don't thank me, thank them... and yourselves for that matter. The feedback we're getting is encouraging to say the least. Exciting is more like it... and it seems every problem I come across, you guys have an answer. Even some of the ones I'm not aware of yet (like the FPR in the tank) are brought to my attention without me even asking.

You guys kick ass. If I can get a cheap intake built with a little help from my friends, its the least I could do.

PetersRedYaris · 03-09-2007, 06:00 PM

What about ONLY making a piece to mount the m.a.f.? By keeping all the origional rubber hoses present, one could remove the entire plastic airbox, mount the m.a.f. in this new short piece of pipe, and put a filter on that. It would be short, it would have good flow, and it would be EXTREMELY simple to produce. I only ask this because I would like to keep that small rubber hose where it is and have no second "tiny filter".

Oh yeah, good work Chino!!!

jdubau55 · 03-09-2007, 06:47 PM

The steps arent something a lil silicon gel applied to the joint to make it a smooth transition wouldnt take care of. Also, as long as the last piece is the same size as the TB opening it wont really matter. When you decrease the size it increases the pressure as well. Im no fluids engineer, but maybe a slightly larger at one end going to slightly smaller at the other would make a better intake? In anyway the amount lost from this system pieced together like it is will never be noticed. Even on a dyno the difference would probably go un-noticed.

Great job with this CC. I like seeing people that don't just go out and buy what is the "best" but rather DIY and get good results. You get more satifaction that way.

That is more or less what I have, but there's not really enough space due to the length of that first piece of tubing.

ChinoCharles · 03-09-2007, 10:08 PM

There seems to be a misunderstanding regarding the smoothness of the interior of our proposed production intake. Let me clarify.

This intake kit will include a 2" to 2" coupler, a length of mandrel-bent 2" pipe with a welded MAF mount, a 2" to 3" coupler, a VERY short length of 3" tubing that will not be visible in the system, and a filter... and the necessary clamps. Now, think about this... the first joint is on the throttle body. You have 2" pipe coupled to 2" pipe with a 2" coupler. Smooth. Second joint is 2" pipe to 3" pipe, but the coupler is cone-shaped so the airflow coming into your 2" pipe still isn't hitting a flat surface (in relation to airflow). Everything is SMOOTH. The version on there isn't and it still works like a damn charm, so I have every reason to believe the next version will be that much better! Seriously, I feel bad for you guys that you can't sit in my car for a minute and hear that engine. I've had quite a tough time keeping my foot off the floor.

I WISH I HAD A FUCKING DIGITAL CAMCORDER! Anyone in Ohio willing to hook a video up for me?

Sure, we could manufacture the plates and sell them, but then what? You guys are talking about using silicon adhesive on your permanent intakes? I can't condone this shit!

All kidding aside, the real reason is this... OK, so I make the plate and weld it in and we sell them. That is 75% of the work right there... you're going to pay 75% of the price. All you're getting over that is couplings (which are cheap as hell), hose clamps (which are also cheap as hell), a length of 3" pipe (cheap) and a filter. This is why I don't see any reason to just sell the MAF plate. Leaving the filter out... that is definitely going to be an option. I guess we will probably sell the MAF tubing also, but understand you're going to be paying close to what it would cost for the whole she-bang. 75% of the research, time, effort, work, bought parts and tools... have been associated with that little length of pipe.
