Forced Air Induction

Here's a little trick I'm trying out. A NACA Duct in bumper to sealed air box.

Not sure how this will work driving in the rain especially with a sealed air box

It’s not worth the hassle. I’d like to know what you think though. I’ve tried this and just didn’t see any real improvement.

I'm hoping it's just getting air from a cleaner source than the wheel well/fender liner.

Somewhat related, I remember a long time ago someone did a test on a 2002 LS1 Trans Am with the WS6 and without (keep in mind its N/A). The car had to go over 120mph for the Ram Air to add anything.

more peace of mind for me I guess when driving offroad and not sucking dirty air from the engine bay or wheel wells. Also better looking/stealthy than a snorkel

In that experiment they Probably just used a tube of some sort mounted behind the grill or in a headlight recess. I've seen some still do it that way with PVC pipe, but isn't very effective like you said... The duct that I used is 8 in across, then tapers down to 3in so it's gathering a lot more air and force feeding it.

Factory optioned WS6 vs the regular Trans Am. In order for ram air to be effective (at least for N/A gas) it has to be a completely sealed system, which it looks like yours is.

What's the gain sucking through 3" tube?

Probably nothing... But, I won't be sucking dirty air and dust an engine.

It probably would if I didn't have a second larger hole in the air box. This will have to do until I can make some sheet metal fender liners. It sure is a lot easier to work on without them though!
