Ever used Dry Ice to cool your car?

Just curious if anyone ever used dry ice to cool their car near the radiator or intake...in 02 when I lived in St Louis a few people were using it on their inter coolers for their subarus

I know on my dad's old race chevelle he had a little can that he looped the fuel line through and would put dry ice inside the can.. I'm not sure if it would work the same with F/I though?

Most of the time this method is used for boosted cars.
Cool the intake charge as best as possible on those hot days.

Never tried it on my N/A car though.

It would be a temp. fix.

As soon as you got in line with the car running...it would jump back up to heat.

IN every day use it won't do you a bit of good. Its an old racing trick to quickly cool the motor down after a run to keep heat soak to a minimum. The thing with dry ice that you have to really careful about thermal shock as the drastic differances in temps could have catastrophic results.

I have done this before on my old Grand prix supercharger....its not a good idea...theres a thing called vapor lock...and its somthing you want to stay away from... trust me. dont understand? heres the deffinition,

When gasoline overheats and boils inside the Fuel line,Throttle body, intake or fuel pump of a hot engine, it ceases to flow. This can cause stalling or hard starting. This is called vapor lock, and it usually happens during hot weather. If a hot engine won't start, all you can do is let it sit and cool off. You should check the cooling system to see if anything is causing the engine to run unusually hot
which actually makes no sense if you want to cool your car from a cruise or w/e.
It is an old racing trick, but ill tell you from experiance, its not good for the block to cool and heat up like that. I cracked it and then it becomes a stupid idea.
