CAI 'cavity venting' - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

themossman · 10-28-2009, 06:34 PM

I would be interested in opinions on 'venting' air into the cavity(regardless of manufacturer). It appears most of the products shield the area where the OEM box and a little vent to the front grill...thoughts?

I removed my washer fluid bottle in hopes to get a little more air in there....but I haven't noticed any change.

Hey Mossman, I have done this on my car. I have a LMR CAI like you. I cut a 3" hole in the side of the plastic shield thats behind the lower grill and ran a flex 3'" tube up into the CAI cavity. It fits in between the washer bottle and plastic fenderwell. I believe it is getting cooler air in there, especially at speed but I have no proof of that. I think it would work as well as the air scoop that ADM is offering for thier CAI. I could get you some pics if you want, my car is in for the year.

I would be Interested in seeing some pics?

Thanks.

Our scoop does just this-No need to design,we already did all the leg work!

Do you have any pictures of the unit so I can get an idea?

Thanks...

Yep, the ADM scoop is perfect for pulling air in through the lower grille and up into the sealed airbox. It really opens things up! I am really happy w/ it.

In order for air to move from one place to another there must be a change in atmospheric pressure.

The laws of Physics show that High Pressure always seeks Low Pressure.

On the intake stroke of and engine a Low Pressure Area is created, and the atmospheric pressure we live in rushes in to fill the void.

This Low pressure area builds all the way to the filter where Low pressure Meets High pressure.

So If you can imagine an Ora of Low pressure area around the filter.

Anything we can do to remove obstacles for air to move to fill the low pressure area the better.

Now Turbulence is a whole other Obstacle for air to move around, and we can't easily see turbulence so Only scientists with the right equipment can help us with that.

One thing we Can Not do is Force air to move, to an area with equal pressure, it is quite stubborn and only reacts to pressure changes.

The best we can hope for is Cool, Clean, Non Turbulent air, to fill the low pressure area created by the piston.

Best be careful Ted, There are a lot of facts and "myth busting" material in this post. Could get you in hot water.

Keep up the good work. I've been doing this stuff a long time, but I've learned a lot from you here

I try and try and try but I just can't change the Laws of Physics, NOPE can't even bend them a little.

So, if I'm interpreting this correctly...the goal then would be to maintain pressure around filter without creating turbulence?

If that's accurate...then I would think that routing air into the box might cause more problems that it solves... ???

Again we can't see turbulence

I don't know that you can manipulate Pressure, but you can clear a path for the air to enter the area around the filter.

The Filter is your Low Pressure Area, the High Pressure is going to take the Path of Least resistance.

This is why the CAI with gaps around the air boxes had increases in IATs, air is going to rush in from everywhere it can.

Sealing the Box from Engine compartment Air, then Providing a Path for OUTSIDE air to enter the box is the ultimate goal.

Ted.

wrek · 10-30-2009, 07:43 AM

You also need to keep in mind how much air the engine sucks in when at speed and make sure your intake path is large enough to accommodate this amount of air.

Gotcha....

What I would really like to see, since I have an SS/RS and the 'fog lights' are worthless DRLs, would be a product that replaces the fog lights with plumbing to cool the brakes and, on the drivers side, the air box cavity.
