Keeping intake air cooler without rerouting intake.
I think I now know how to cool the air off in the summer time
without rerouting anything.
I will work on it and post it when I get the results.
Keep in mind this has to be low maintenance and low hassle so I am not using ice .
I may be able to keep the intake air as cool or cooler than the outside ambient temp.

Interesting, what's your plan or is it a secret?
I thought about cutting a vent into the hood and make it sort of like a ram-air, but decided that defacing the car would probably not be worth the power increase.

Well, then this is obviously an active system if it can make the air cooler than ambient. If it isn't ice, I'm betting it's some sort of Peltier device. If that's the case, you might as well give up right now. Peltier devices are too inefficient for these purposes. They'll suck down a lot of power and provide VERY minimal cooling capabilities at the expense of increasing underhood temps more than they cool off the intake air (mere fractions of a degree, if that, when running even at idle).

1) Dissolving water into the air
2) Electric cooling of some sort.
3) Compressing air somehow
Electric/compressor cooling of any sort always results in a loss. Driving any compressor or peltier cooler would put such a strain on the battery/alternator, that any gains from denser air would be more than lost by the alternator.
So... I'm predicting that this project will fall *way* short of bringing the air temperature down below ambient, unless it involves traditional water spraying. (Not to be a party pooper - just being a bit realistic here)
A really funny thing like this happened in real life. A mate of mine thought it'd be a great idea to reroute his air intake from his 3.0L v6 Magna engine through the airconditioner first. He figured that the few kilowatts he might lose from the compressor being on, would be made up by the 20 degree drop in temp or so.
I tried and tried to talk him out of it, but he went ahead with it. I thought it was just plain not going to work, since you can expect a 7-10kw drain from a compressor, and if you're lucky a 1.5% gain from a 20 degree drop, but the end result suprised us both (Now that I've seen it it doesn't surpise me)
The A/C system was such a restriction on the air intake, that when he revved much past idle, the engine would just stall and a Check Engine Light would turn on. The A/C Simply couldn't supply much more than a gentle breeze, even on full!
