RAM Air idea... Comments
I am about to do this, but I wanted people opinions first b/c im not the best at engines, but I understand the basics.
I have seen everyone doing the RAM AIR by putting ducting at the bottom of the front bumper light and into the air box, but this always seems really complicated and as if it doesnt pick up enough air. the best one I have seen done is the one at the bottom of this page:

But I have an idea by using "sleepy-eyes" for ram air.
Sleepy eyes cant let air get to the engine better unless you actually cut a hole behind the headlight. The headlight actually sits in a small steel box of its own, it doesnt have any real way to get air to the engine from what ive looked at on mine, but maybe you could cut a hole in it and instead of running the tube down from the fog light, you could cut a hole behind the headlight and run the tube behind the headlight and into the box. Then when you had sleepy-eyes on, it would cause a ram air effect...
I would love comments on this before I do it, it seems like it would be ALOT of air being pushed in to me...

the idea should work... i know that there is more airflow over the headlights in sleepy eye mode than when they are closed... my headlight actually moved up and down when moving at high speeds... cutting the hole in in the radiator core support would allow you a straight shot at that air... so long as you made some kind of scoop to gather that air in and direct it to your air filter... in essance ram air...
i would mock up some kind of scoop with cardboard and then cover it with vaseline and fiberglass over the cardboard to get it in the shape and location you need it to be... as long as you keep it straight then it should all work out... take lots of pics of the progress... i would like to see how well it turns out...

Ram Air Hoods and such are nothing more than fancy Cold Air Intakes. Ram Air setups cannot pressurize air in their current form.
I don't personally remember the math, but there is a page out there somewhere that uses it to explain the reason why Ram Air actually doesn't work.
You would have to radically redesign Ram Air for it to work, not to mention, given the best possible intake configuration you would need to be traveling at supersonic speeds to see any measureable increase in air pressure.
Ram Air does get you cooler, more dense air, wich is always good, but it is not any better than a good CAI will get you. Plus you introduce increased drag, without a justified performance gain to account for the increased drag.
Ram Air is not bad, and if you have one there is no reason to run out and switch to something else, but there is not special "Ram Air" effect that gives you some magical performance jump that you cant get out of a quality CAI setup.

Ram air will cause drag in the QMT, but if your objective is to cram air together to make it denser and colder I don't see anything wrong with that...... But you will have to hit speeds higher than 70 MPH in order to see a difference in the power band.
At the same time once the air moves to the TB it already begins atomizing at hotter tempratures making it less dense anyways.
It will become a toss up.
Honestly I don't know why people focus on the cold air theory, which to real world conditions isn't that effective for what you pay for.
Honestly I would focus on keeping the engine cooler using synthetic oils, oil cooler kits"adding 2 more quarts of oil". Dropping the engine temp will signicantly raise HP. It will also drop coolant tempratures.
Also look for better coolant pump methods such as an electric water pump that constantly flows coolant at any RPM, or even an electric radiator fan. Also think of using an aluminum radiator it will disapate heat from the engine 3X faster than your average OEM steel radiator.......
Doing these types of modifications drop the temprature to the head and intakemani ultimately keeping air denser until mixed in the compression stroke with fuel......
