Cowl induction for cold, ram air for the Si?

[mattsbobo]

Can't wait to see the progression on this one Nitrous.

I tried to rep you but, "You must spread...". You know the drill.

I've been working on this too over the last few weeks too and am goingg along the same lines. However, I've found that you don't need to cut the firewall to get cool high pressure air. There is a metal panel just below the plastic wiper cowl, just cut through this piece & you will have access to the vent holes in the cowl.

*EDIT* Bill, I reread your post & now see you already have the same idea as I

It is a great idea, but I'm not sure if the cowl area on our car would be pressurized as much as with older cars due to the design of the parts near the base of the windshield. The plastic cowl sits almost flush with the hood with vents on its front side. The back side of the cowl dips down before coming into contact with the windshield and would be the best place to have air enter however, there are no vents on that side.

You would still get cold air thanks to the vents on the front side of the cowl, but the cowl itself would be more pressurized if there were vents on the back side of the cowl.

If you were in Arizona you could open extra holes at the back, but where I am snow will block those shut.

some great ideas nitrous! keep us updated

Vision makes a cold air vent for the EP3 and RSX. I wonder if the RSX could be fit to FA's & FG2's?

See, if this community puts its collective heads together, we can come up with something on our own. There is a wealth of information on this forum and there are some brilliant people here as well. If we will study these issues that confront us, I know we can come up with some solutions.

Bro, can you post a link or a pic? People need to visualize these things. If there is already something out there that we can adapt, all the better.

Man, I love you. This is exactly the kind of piece I was thinking of.

[F-1 Si]

I think this is the right piece just the wrong price.. I'd be willing to bet something like this can be sourced from a race web page much cheaper. I think what your looking for is generally used in brake ducting. Not that dryer hose material more like a molded plastic.

here are some

NACA Ducts

this one could work in our cowl

their would still need to be an induction box for the filter to sit in.

[NitrousG35]

Here are three classic ways that have been used to bring cold, ram air into a motor. All use high pressure zones.

1968 Hurst Olds with bumper scoops ducted to the air cleaner assembly:





NHRA Pro Stock car with high mounted hood scoop:



Picture of where high pressure area is on a Civic:

Right. There will need to be a box fashioned that will enclose the filter element. At the end of the box, a circle will be made with a round duct fitting. This would then connect to the duct on the firewall via some tubing used for brakes or cold air packages.

Peter, I love you twice. Man, this is great. Obviously you are an F1 guy because they are into the engineering of a car outside the box. Repped +

[F-1 Si]

It really wouldn't be too hard to mock up a "u" shaped enclosure for the K&N Typhoon using their heatshield and then ducting it to the underside of the cowl.

true but i think a whole box would be the best bet, since i would be closer to air tight.

Thanks Man.....I think K&N wanted to keep the MSRP below 300. Adding an enclosure would of brought it to the 400 mark.

Looks like it's time to buy the K&N. I'm not big on "barking intakes" so the enclosure idea makes alot of sense in terms of performance and stealth factor....
