I got this idea off of reading some other's posts. I don't think anyone has done it quite this way, so I want to get other's opinions...

I used a 3" 90-degree qwik-ell from home depot and connected to a 3" PVC. The PVC runs down below the headlight.

It seems to work fine. I haven't noticed a huge difference, but only about 5 minutes of driving time on it.
I'll post longer term results with respect to mileage asap.

Any comments??

Might want to put some kind of screen on the open end of the tube, might suck something up and clog the tube. Can really tell where it comes out, is it by the headlights? Is there good air flow there? Might want to continue the tube a little further down.

Well, you know the gap between the headlight and the bumper? That's its source of air.

So, it's not "true" ram air because the tube doesn't port straight out the front. It just pulls air from a different area, one that gets fresh, cool, air easier than the stock area.

I thought about the screen but wondered if that would hamper air flow even more?

Your not gonna flow anymore air, cause you still have the stock air filter (I assume), but you will benefit (slightly) from the cooler air. In my area, it's butterfly and bug season, so I'd be concered about sucking up all those bugs.

It will NEVER be "true" ram air, you will never be travelling fast enough. Fighter jets use ram air systems, not passenger vehicles. All you are doing is moving the inlet point to a different location. You are not getting any more air into your engine, only possibly cooler air. From looking at your setup all you are really doing is allowing your filter to become dirtier quicker.

Sorry to burst your bubble, but I'd hate to see you spend the equivalent of an aftermarket intake down at Home Depot, only to come away with almost zero results.

Well, if you can get an aftermarket for under $10, then show me where...

Anyhow, it's worth a shot.

You might see a marginal ram-air benefit if you get it in the air stream and positioned well. I think temperature wise, that's probably no different than pulling from the fender (maybe worse at idle when you pull heat from near the radiator).

The fender location probably gives a much less turbulent air source to draw from, IMO. I like your ingenuity though.

Not true. Ram air firebirds put out the same rwhp (and same weight) as their Camaro counterparts, yet run faster times at the track. Ram air is used in Indy and F1 also. More pressure ahead of the TB means more "free" pressure drop across it, means it can flow more.

The science behind inline turbine engines is a little more complex, apples and oranges.
