i did a quick search and just found one thread on the shelby forum. someone asking about putting dry ice in the reservoir and then people saying no dont do it, its a bomb!!
but that's if you drop it in and close the cap. then the gas has no place to go/escape.
what if you were at the track. you make a pass. then go back to the pit. you leave the car running so your pump is on (or manually turn it on), circulating the fluid. you drop a chunk of dry ice in the reservoir to cool the fluid down. when the temp drops, you pull it back out. meanwhile leave the cap off so all the gas can escape, which i believe happens immediately with dry ice.
someone mentioned that it has some kind of acidic property in it which would be in the coolant but i dont know how accurate that is. i was discussing this with a friend who is an engineer and as he mentioned they put dry ice in the punch at halloween parties. its just frozen C02, which sublimates into gas. if you seal it up, it will explode. but if you leave it open so the gas can escape, then its like a punch bowl. right?
the benefit of dry ice over regular ice is not having to drag a ton of ice with you to the track and having to remove fluid from the system as you are adding to the volume when you put it in. with dry ice, it would be like dropping in a blue ice pack and then pulling it back out. no real change in volume. no siphoning coolant out. and it will cool down much quicker.
