Dry Ice At Indy

[Jack McCarthy]

my fuel checked @ 54 degrees at bowling green for record run on hottest day of year so far in kentucky... with no artificial help ... just chilled fuel for several hours prior to heading to staging lanes, have well thought out cool can and insulation for lines...

has been checked as low as 48 degrees ... just use you head and manpower, save money and risks

and the temp guage was still on 100 at scales

Can you get the fuel to cold, and it creates condensation in the carbs?

[Jack McCarthy]

it doesnt help as much when outside temp is under 70 degrees
never had it slow me down !

If you hold a piece of dry ice too long, it feels like it is burning your skin. Your skin isn’t actually burning, though. What is actually happening is that the dry ice is freezing your skin. The dry ice is carbon dioxide that has been frozen at -110 °F (-79 °C). That’s why it hurts when you hold it too long, because your skin is starting to freeze from its cold. Freezing skin is a bad thing, so I recommend not letting dry ice ’burn’ you.


The reason that freezing and burning can feel the same is because touching things that are very cold can do the same thing to your cells as touching things that are very hot. The burning feeling comes from some of your skin cells being damaged and breaking open. This happens when the cells’ membranes are broken open. (You can think of the cell membrane as the wall of the cell.) If you touch something hot, some of the cell membranes are actually melted, breaking the cells open. If you touch something very cold, the water in your cells turns into ice, forming crystals that can tear through the cell membranes. In either case the result is the same - the cells are damaged. This is what you feel.

Wow that was a great explanation. Thank you

found this on NHRA's website under rule amendments for Alcohol dragster and funny cars.

“Artificial cooling and/or heating of fuel (i.e. cool cans, ice, Freon, etc.) prohibited on the car. Insulated fuel lines and fuel tanks prohibited. Artificial cooling and/or heating of fuel confined to the pit area only. The use of dry ice and/or liquid nitrogen for artificial cooling of fuel prohibited.”

Doesn't mention that under Super Stock.

It's like anything else, judicial and intelligent handling make the product safe but there will always be someone that will act just plain stupid.

Should you ban NOx at the event just because some idiot might try and sniff a bottle?

Somewhere there has to be a balance and people have to take responsibility for themselves.

Only a matter of time.

My guess something they were doing was getting out of hand.
