Just wish there was a video of the Taco in a wind tunnel.

A Tacoma in a wind tunnel is no different than any other truck.

Lots of smoke bombs, leaf blower, video camera. There's your answer.

As others have said, the placement of the scoop is not in the correct spot. Although I think it can have some other function by making it another place a cai can draw fresh air from but it wouldn't have a ram effect, just another air hole and you have to do a lot of fab work under the hood to have it connect to the cai box. Even then, it would still be a waste of time and money. It's strictly for looks. You should look into a cowl hood instead.

I think I'm going to install an electric leaf blower my intake now. Throw a capacitor inline to make it more effiecient. Sound good Austin?

HAHHAA someone beat me to that idea...

shit, I'm going to do this on my POS civic now! LMFAO. I could care less If I break something.

That is soo hellarious though. If it was possible to get an efficient electric leaf blower that could put out enough cfm, I'd so do it! Just throw a large capacitor inline to keep it from drawing on the battery, insulate it and go. I have a 93 civic that would love that thing..... riiicccccceeee! Sorry, I am partially redneck if you haven't noticed.

What ever floats your boat dood...LOL...I'd be interested to see what happened.

i made my hood scoop funtional about 2 months ago. in those two months, there have been no positive or negative changes in the mileage or power. so take it from my experience, making it functional makes no defference in performance.....what it does do though is give you better water crossing ability. i've gone through some very deep water. having the air come in through the scoop allows you to see how much clearance oyu have over the water instead of guessing, as well as raising up the intake point by about 8 inches (semi-snorkle...emphasis on the "semi")

i did take a lot of time to make sure that if water did get in that it would drain it out before it got to the engine. so if you take all nessesary precautions, you'll be happy with it as i am.
here are some pics

colinb17 · 05-02-2009, 11:19 AM

fyi, i know it looks like a lot of extra distance for air to travel by routing it that way, but the blue hose is retractable, so when you close the hood, it retracts, making the distance the air travels nearly the same as stock.

brian · 05-02-2009, 11:26 AM

I knew it wouldn't take long before someone did it :P Good info!

FWIW, The way the intake is poositioned in the fender in the stock location, you can have water going over your hood, as long as you keep going. With the air comming in thru the intake, once water goes over your hood, you risk hydro lock.

Ridgerunner · 05-02-2009, 07:04 PM

To be effective, a functional scoop must be located at a high-pressure area on the bonnet. For that reason, some functional scoops are located at the rear of the bonnet, near the vehicle's cowl, where the curvature of the windscreen creates such a high-pressure zone, and may be placed so that their opening faces the windscreen (a reversed scoop).
The scoop will be most effective if it is either mounted high enough to clear the boundary layer (the slow-moving air that clings to the surface of a moving object) or if it is a "NACA duct," mounted below the surface and designed to draw the faster moving air outside of the boundary layer into the duct. A shallow scoop that is not a NACA duct may not admit a useful amount of air even if it is open.
Under the bonnet, an effective scoop must funnel air into the engine's intake in as short and direct a path as possible, preferably through a tub or channel that is insulated against underbonnet heat.
A scoop may be part of the bonnet, or may be part of the engine's air cleaner assembly, protruding through a hole cut into the bonnet. Such a scoop is called a shaker hood, because the scoop vibrates noticeably when the engine is running, especially under power
^^^^^This came from Wiki. Your non-functional hood scoop is just for show because in the center of that hood is an air dead zone.

Listen I hate fake stuff too like "nonfunctional sidepipes" and such. I think I would be totally annoyed that such a cool feature as your scoop doesn't do jack-but the stack of attributes your truck possesses sort of kills the scoop thing anyways

The only shot at real getting of air would be cowl induction, or a wide scoop right at the nose with a slight downturn(fugly) or a shaker which is direct to the throat.

You wanna trade for a non scoop???

TheTacoManChach · 05-02-2009, 07:34 PM

3. Is turned around, and moved to the base of the windshield.

Chris don't we call that a Cowl Induction hood? Not a Hood scoop?

And has anyone tried installing dry ice in their CAI?

Benefits?

In? or around the CAI? Dry ice is compressed carbon dioxide. If you put it IN your CAI, as the ice "melts" the released carbon dioxide would definitely hurt combustion. Putting it around the CAI may help cool the intake charge and may make a little more power.

matthew5olson · 07-11-2009, 08:14 PM

I was just about to hook my scoop up to the intake. What I'll do instead is have the intake for the ram air system behind the grill. And don't say there's no air getting there! I'll probably still open the hood scoop though. If its a low pressure area it should suck some of the hot air from the engine out and allow the heat to escape at idle. any thoughts
