Subject: How do i make the air colder using dry ice

    Hi as part of my final year project i am working with a team on the 
formula student SAE car. As part of the regulations we are limited to an 
air supply through a 20mm air restrictor, this is situated before the 
inlet manifold and after the throttle body. My aim is to get the incoming 
air as cold as possible (-100 degrees c) so that i can ram more air 
through the restrictor, creating a more better air/fuel mixing ratio.

So i am now looking into dry ice, i have been reading your web page and 
the sorts of things you can do with dry ice fun games, but nothing told me 
how i can make the air colder and once it has reached a certain 
temperature how do i maintain it..

It would be nice of you to get back to me or recommend any books that 
might help me with this....

Look forward to hear from you..
