The only thing related to this I have heard of is having intake components in a freezer prior to a race. Of course it's obvious they wouldn't stay cold very long...but I've never tried anything of the sort.

 

i know a lot of people who before they go drag racing or driftng, they put bags of ice on thier intercoolers before they go, and then after, it helps ****load, as the cooler the air the better you have.. its really good for small blips around strips and stuff.

 

unless you are running a seroiusly built or boosted motor that puts out a lot of heat... you arent going to really see any gains

 

hmm a special made intake filter cone..that u can hide dry ice so u can have dry ice in ur intake..and dry ice wont melt that fast...and it goes straight from soild to gas....so...hmm...more hp?!!

 

Actually to go along with what pearl said above me, a friend of mine had his short ram intake sitting over a bucket, can't remember what it was, filled with dry ice, don't know if it helped that much but he kept filling that thing up every time to make sure

 

i saw a test someone did by putting a thermometer on or in the air filter which you could read the tempurature from in the car and with a cold air intake the intake temp was pretty much the same as the outside temp, like 2-3 degrees hotter only, and the air coming in actually got colder than the outside temp when you were driving faster, but with a short ram the temp. was like 20-30 degrees hotter at a stop and then it didn't get to the same temp as the outside air until 35 i think and then got a little bit colder than the outside air at 65. all of this was on a celica gts so it might be a little diffrent for a lancer, so it seems that for drag racing a cold air intake should actually make a diffrence over a short ram but once your moving a short rams about the same. but if you had a car with a really hot running engine the cold air might soak up more heat when you were sitting still.

 

Honestly i think it would only help at the start of the run because once your up to speed the air will be moveing so fast through the engin compartment that ice or dry ice, or freezeing stuff won't help much, most of the cold air ice would provide would just be blown away and the little that did go down the pipes wouldn't make that big an effect, it could though *shrug*

 

well instead of dry ice you could get the ultimate in intake air cooling gas--nitrous oxide, but thats a little more difficult to set up and expensive. also i remebered i saw a new product that was in r and d stages using compressed oxygen or just compressed air maybe, i don't remeber exatcly and it was blown into the intake to cool the air a lot, it was a similar setup to nitrous with a small scuba tank type of thing and some special injectors and they said it wouldn't be as effective as nitrous but it would be safer and the compressed air or o2 is a lot cheaper than no2.

 

correction the dry ice is to be on the outside of the box or around the intake pipe itself...here's a top view cut of what the box should be like...so i stand ocrrected the CO2 will end up messing up the car...i did a search on www.ask.com and a good amount of articles popped up from people using this technique ranging from old school v8 drag to Formula Cars...from what i read the dry ice can cool the air upto -75c.

 

i wouldn't expect massive amounts of hp out of this...nore would i spend time or money building this...its a cool idea...but with the money spent buying dry ice all the time and building that..your better off buying a CAI.

 

about 2% per ten degree defferential is a close approximation of the gains from changes in air density. Be careful not to get droplets of water though as they do no good when the strike the rapidly spining parts in your turbo.

Yes cool humid air is a good thing as the added moisture evaporates, then converts to steam. This tends to retard combustion there by preventing detonation by absorbing heat energy that could otherwise cause pre-ignition.
