Custom CAI(at last)

[Katana]

Because I got bored waiting for a tuning company to produse a CAI for my car, I decided to make one of my own.

Here are some pics

Good place to get some fresh cold air! Now you need to frabricate a plate so you can block off that hot exhaust.
P.S. I like the little horns on your toyota symbol...haha!!!

[Katana]

Thanks.

I really need to find a plate cause the exhaust manifold is really burning the incoming air!

The horns on the Toyota symbol are an idea of the greek Yaris club.

Thanks for all the good remarks.

I keep thinking of a frat when he says "greek yaris club" haha

Did you happen to feel any improvements?

Looks quite nice, too bad the engine block below looks so... naked! Who'll be the first one to polish/paint their engine head?

Also, that long, lonely pipe is begging for a turbine as a friend

Οh yeah, above the 3500rpm the car really goes great now!It has gained at least 5hp!

Yeah it is very naked now...

I would like to paint it!Also, as far as a turbine is concerned, OH YES!

That actually doesn't look too bad Katana. If you can just isolate the filter from the engine bay a bit you might have something going there.

[Katana]

Well, as my friend ChinoCharles says, I think that I have not discovered the full potential of this stuff.

First of all, I don't know if you have noticed it, but there is a small hole behind the grill, in the front right part of the car.I think that it has to do with the 1.8lt model(maybe for cold air).

So, my custom intake takes in fresh cold air from that hole.I am trying to find a way to take off the hole plastic cover from the inside, so that the intake takes in great amounts of air.Certainly, I would not like to cut it, because in rainy days, it will protect the engine from water.

Finally, as ChinoCharles states, I have to figure out a way to isolate the filter from the exhaust manifold.

If you have any ideas on that, feel free to express them.

Thanks for all the posting guys!

CF shroud might work pretty well, btw, check your PM's

Is it giving you a check engine light? a friend of mine lend me one but i was getting check engine, apparently the MAF sensor was detecting too much air. How can i override this?

[ChinoCharles]

It looks like you have some frame there to work with. I saw someone do this for a CRX... he needed to isolate the filter from the manifold so he took some cardboard and began cutting and bending and marking for holes in the car until he had a general mockup of the piece required. Then just fab up a piece with some aluminum or something. I think he actually used the cardboard for a while... you know how CRX owners can be!

At first I had had this light.Maybe it had to do with the new readings that AFM/MAF sensor was reading.After 3 hours it turned off.

What engine does your friend have?Where has he put the AFM sensor?

ChinoCharles tnx for the advice.

You are not affraid to receive water on your air filte??? Cause it was located directly behind the open grille when the water is going throught!

[Katana]

Εxactly.That's why I am trying to find a way to easily install and de-install the plastic protective cover.

wait.. CAI is cold air intake right? i havne't done my researching but what does CAI do for your car? aside from sucking cooler air then the normal? and how does sucking cooler air translate to more HP? is that how it works?

[ChinoCharles]

Cooler air is more dense than warm air because on a microscopic level there is less mollecular movement of the air itself. In other words, you can cram more cold air than warm air into the same space.

The first two strokes of an internal combustion engine have to do with first taking air and fuel into the combustion chamber, then compressing this mixture right before ignition. A cold air intake does a few things to help this process along. First, it (usually) relocates your source of air further from heat-producing parts of the engine, hence the term cold air intake. Second, it (usually) cuts down the length of space in which the air has to move, thus your air hits the intake manifold at a higher speed. Both of these facts mean more air in the combustion chamber, and more air means more oxygen which means a more violent ignition... which means more HP!

Εxcellent explanation!It couldn't be better!
