Cowl induction for cold, ram air for the Si?

[soxfan143]

So where are we going with this? We need to figure out what way we want to go. Do we want a CAI with an extension on it or do we want a stock style air box that will be fed cold air from outside? Or do we want to feed air from the cowl into a stock style airbox? I still believe that the Gruppe M style induction would work the most efficiently and would take less to modify to what we want. But it would be WAAAY to expensive to buy and chop up and we don't even know if it would work because of the master cylinder. I would like the Simota air box setup just because we can use most of our stock system. But again I don't even know where to get one. So what do you guys think? I've seen alot of things we can do. I'm stll going to check out a Ford setup tomorrow at work since I wil be able to see it in real life, not on a computer screen, and figure out a way to make it work.

I sent Simota an email with a link to the 8th Civic to show them a small sampling of what's going on in the US market place. I know they only sell quanty to dealers\whse distributors etc. I asked them for specs on some products. I did see a kit they had for the euro civic(which doesn't use a MAF), I also sourced a MAF adaptor which can be incorporated. Hopefully I'll hear back or I'll have to contact one of their dealers and buy either the RSX box or Civic box and have it shipped over.
The Gruppe M box ix big $$. I really don't feel like hacking up a Gruppe M at this point.

I'm not a fan of using our stock air box and factory tubing. We need something that will be able to flow 10-20% more air volume or at least have reserve air flow.

For the best response, it is better if the filter was enclosed in an as large enclosure as possible and the intakes hosing kept short. A simple experiment to illustrate what I'm getting at would be trying breathe through a thin vs a large dia straw. Take a sharp inward breath through each stray in turn & you'll see what I mean.

Good point. The concept is good, but the area around the filter needs to be larger to enhance breathing. I posted this as an example of where I am going. Hopefully, we can find an enclosure for a cone type filter that can utilize a high pressure zone.

Right you are Peter. I am afraid that trying to adapt our present system will be an effort in futility. The issue is air volume as you aptly said. We need a box that is large enough in area to allow the filter to draw in sufficient air.

I have had the respiratory flu, so I am a little out of commission. When I get back on my feet, I am going to take a hard look at the cowl area and see about accessing the area also used for the ventilation.

Damn Flu..You need a good dose of HOT NURSE.. As soon as I get some warm air out this way the cowl gets taken apart. I'm waiting on some info like I said earlier.

you will have to cut into it, the only problem is that the air will find its way towards the back of the firewall rather than the airfilter, unless if you correct the problem by finding a way to redirect the air(plastic tube/??) but then how will it be held up...

Convex air deflector almost like a chambered muffler..

This is where I see a ram air type product going. I posted my idea in regards to this setup about 6 months ago. Is the black plastic insert for the fog light easily removed from the bumper or is it bonded to it? Ie can I remove it to modify it and/or replace it easily with a factory replacement. My idea was to cut the fog light hole out, install a ram air tube that connects to the factory airbox piping and remove the resonator and tube to the fender. At a minimum it would provide cool air into the engine if not directly connect to a future X-intake cold air box.

NitrousG35 will be sending you some pics of a ram intake I have on my car for research.... Also here is something I poted a while ago:

The expression "ram air" typicaly refers to isolated combustion air for the engine that is forced-fed from vehicle velocity(speed)If taken from a high pressure area(foglight location)any forward facing air intake should be capeable of increasing the force in the inlet system. Because the inlet is supplied at over ambient temperature, the manifold density is increase as a result. One can calculate the additional force by applying the equation

Yeah I would love to do something like this but have no idea where to begin. lol. Nice write up.. repped.

This is how we modded GlxyGry06Si's front bumper to allow more air to hit the aem cai he had.

Hey Bill,

If you come up with a design I work on a Pro/Engineer CAD system and can model up parts for you.

I'll take you up on your offer. I'd like a plastic piece that fits in the 125mm x 75mm ellipse (fog light hole) that could be epoxied in. Have it taper to an outlet that is roughly the same diameter as the pipe in this picture. I would remove the resonator box and fender tube and connect this new part to the prexisiting tube.

rough sketch:

What picture?

im thinking of making a mock-up out of plexi glass, with one hole on top of the box and another on the back. with the filter inside of the mock up plexi box.

[Excalibur]

I'm kinda sceptical to whether any of this will do anything Tom seeing as how when we cut a hole in the foglight of GlxyGry06Si's car to let more air get to the aem cai, it didn't do anything that we could feel.
Not to mention that alot of people over on fgcoupe have already done this (they didn't have the x intake though)

ya i think the best bet would be the top cowl, the shorter the intake the better.
