Dry Ice

[Eljssp8@aol.com]

To my beloved fellow enthusiasts:

I was wondering whether the rules allow using dry ice to help cool down the 
engine in between runs? I am thinking about putting the dry ice just at the 
entrance of the air box, and leave the engine running, while waiting on grid 
for my next run. Meanwhile, I can cool down the tires with bags of regular 
ice, one for each tire, thus eliminating the need for a sprayer.

TIA,
