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

going to try avoiding bad weather:badidea: Initial testing felt pretty good!

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

I am on the fence on this one. :thankyou2:

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.:ft:

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.

Is going down in size gonna restrict the incoming air?

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!

Nice work but your engine shouldn't suck dirty air or dust if you have an effective air filter. At off road speeds you certainly won't benefit from any ram-air effect.
And it will be critical that you do avoid bad weather, because it won't be the rain, you'll have a problem with. It will be tire splash when you go try puddles and possible submersion if you have to drive thru deep water. If either should happen, you'll hydrolock the engine.
Honestly, the wheel well, fender area is a cleaner and drier place to draw air from. So long as you have a quality filter, any dust that blows into the engine compartment, will not get into the engine.

The Straight Scoop: Exploring the Science Behind Hood Scoop Design - OnAllCylinders
0.0000176 x air speed in mph² = ram pressure increase in pounds per square inch (psi).
“If you plug in the numbers, you’ll find an increase in inlet air pressure of .142 psi at 90 miles-per-hour. Standard atmospheric pressure is 14.7 psi, so this represents an increase of just under 1 percent. If the air/fuel ratio is adjusted to compensate for the increased pressure, there should be a corresponding 1-percent increase in horsepower. For a 1,200-horsepower Pro Stock engine, that’s a gain of 12 horsepower. Hood scoop pressurization increases dramatically at faster speeds: It’s 2 percent at approximately 130 miles-per-hour, and 3 percent at 158 miles-per-hour. At the magical 200 mile-per-hour mark, the theoretical pressure increase is .704 psi, or 4.8 percent. That equals 56 “free” horsepower.”
I think you should add a lamp shade to your bumper OP!!!

Damn!
Ive been looking everywhere for my laundry vent hose!
Found it!
In theory, you'll get better flow from.....

^ that info is similar to what I was referring to earlier. Thanks for sharing that. It also doesnt take into account aerodynamic drag from the added scoops (thinking drag cars, not trucks) and whether or not the 1-2% in hp would overcome the increase in drag.
