I have read and re-read my 09 NHRA rule book and cannot find where it says dry ice is illegal. I also went to nhra.com and the only reference I could find to dry ice with a search concerned alcohol cars.

From general regs, page 250:
“Fuel/Air: Any method of artificially cooling or heating fuel prohibited
(i.e. cool cans,Freon,wet rags, etc), except as noted in Class
Requirements. Cool cans, wet towels, etc. are permitted in Super
Stock, Stock,Super Comp, Super Gas, Super Street, and E.T.
Classes. Wet towels, rags, ice, etc. must be removed before vehicle
leaves staging area. Ambient-temperature air only; Cooling or
otherwise changing the conditions of the intake air is prohibited.
Spraying the intake with any artificial spray or coolant prohibited.”

From stock regs, page 105, under fuel system:
“All fuel system components (regulators, cool cans, etc) must be installed
not less than 6 inches in front of firewall.”

In fact, the only place in the rules or amendments the words “DRY ICE” are used in under the Alcohol section:

"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"

Now, Just a few weeks ago, I questioned how Garlits got into stock without grade points and several other members on here pointed out he is a past champ, and that is how it works, and I was happy to gain that knowledge. It will come as no surprise to anyone who frequents this forum that I consider the DeFranks as friends. I DO NOT participate in their racetrack activities, so I don’t begin to pretend I know what they do or do not do in prepping their cars for a round of racing. I also have no stock or super stock vehicle competing, nor will I anytime soon, as it is beyond my reach time and money wise. So I really do not have a dog in this fight, except from a definitions point of view, just as in the Garlits example above. I am a huge stock/superstock fan, and use this forum to follow racing, especially Indy, and appreciate the coverage and pics from Patsy Hill, as it is the closest thing to being there. But if an NHRA official was notified and didn't see any reason to intervene, it would seem the "east coast" rulebook has the same lack of wording concerning dry ice as my "west coast" rulebook.

all you folks at Indy, keep racing and having fun, wish I was there!
