Look at it this way.

AC's are inefficient systems. They require more energy than they remove. Your engine uses energy to power itself, and to power the electrical system. And an engine is an inefficient system as well. The AC cant possibly produce enough cold air to feed your engine. The best you can hope for is to cool a medium over a period of tiem that can then absorb some energy. However the AC system in your car is too small to constantly, or even temporarily, cool your intake. It can cool a medium, like water, but it cant cool the air fast enough.

You arent noticing a difference because the butt dyno is very subjective, and not at all accurate. The difference is definitely there. I cant remember the exact number but there are be a difference of over 10hp based on ambient air temps. greater with turbocharged applications.

yea , i get the energy thing .. you can't outsmart the rules of the game , energy, enthalpy, entropy .... is was wild *** idea.

butt dyno .... thats funny

 

imma assume u know the basics of thermodynamics.....refridgration systems can achieve a efficiency of greater than 1...if u remember beta in the equation...heat engines are the ones that can never approach 100% efficient....anyway....even tho is it can remove more heat than needed it is still not a good idea to use this....remember people....power comes from how much air u can pump per unit time....not how cold u can lower the air temp at a given instant

 

you guys do realize that on a naturally aspirated rotary engine all these things are gonna net you like 3hp if you do them right, even methanol.

 

 

Wow, that has to be one of the drunkest posts I've made in quite a while.
Anyway, I agree that it won't really make much difference on an NA.

 

If you are serious about all this, thermoelectric plates could be used, (although electrical load at higher ambient temps) . Its been stated before, this is completely pointless. The gain is not worth the loss. 2~10 degrees of intake temp isnt worth a loss. Stated before, when running turbo, compressing air heats it up. N/a intake temps don't get hot enough to cool if you are already running CAI. If you are really worried about intake temps, just heat tape your intake piping.

 

A good many of my posts are alcohol induced. But I still like the Jato Rocket solution to this problem

 

You talking about peltier setups? Where one side gets REALLY hot and the other side gets REALLY cold... That would totally work except that you'd have to have a heatsink on the outside of your car for cooling.... or a fan or something cooling it off.. Because those things get HOT! But.. interesting idea non-the-less

Some of these operate as high as 200C, so.. on the other side, it would be pretty damn close to -100C You wouldn't have to apply much juice to reduce the air temp... you throw heat sinks on both sides, force your air intake through the cold side.. would probably drop the temp a few deg's....

 

TweakGames is right but what a *****.
