Dry Ice in your fuel cell?
 

This question was inspired by a conversation a group of racers had yesterday. I know none of you guys have tried this but I'm sure you have a friend that knows a friend that has. What was the results? Did it pass fuel check with no problem? What temp was it at fuel check? What did they think it was worth ET wise? Barry

Since dry ice is frozen carbon dioxide, wouldn't it mix with the fuel to a certain extent and basically do the opposite of what oxygenated fuel does?

Chemistry wasn't a strong subject in school so I'm not sure how these items would actually interact. Seems like temperture consistency might be an issue too, not to mention a potentially "sweaty" fuel cell.

I would never do this, but know a guy that knows a guy that has.

He says it passed fuel check just fine. I hear his fuel cel did sweat. I hear the lady at fuel check did take a second, suprised look at fuel temp. Below ambient might cause a problem. Long enough line at the scales and fuel check (Like class at Indy) might bring the temp back up enough to not cause a problem. Understand, I just heard this. He told me this guy he knows, that knows this guy, says he holds the plastic fuel sample cup real tight in his hand to warm it back up some.

You can hear all kinds of stuff.

I wouldn't want to get caught doing it.

I was in Columbus a few years back and the guy pitted next to me and saw him put it in before class but didn't pay attention to the outcome. I never heard of it before until I saw it.

See no real problem with it, but why not just cool your fuel in the pits then pour into the cell before a run? There obviously is no issue with cooling fuel as cool cans are allowed.

I know guys with small freezers in thier trailers, just big enough for a fuel jug.
Half an hour in the staging lanes make that one moot.

Betting even with the time lapse there would still be a difference...how much would have to be measured.

What benefits are seen with Cool Cans?
Does it reduce Cool Down issues?

Re: Dry Ice in your fuel cell?
 

I havent seen one in use in years Dan, but they were common in the 60's/70's.

Rich I would image there would be a big temp difference between cooling the fuel at your pits and putting dry ice into the tank. I haven't raced much in the last several years but a 2 years ago I was at Indy and the stocker parked next to me was playing with dry ice. I had to laugh because it was at least 100 out and they had gloves on. They were new to the stocker game and had a newer car. They must have thought I had no clue as to what they were doing. I walked over into their pit area and they reached into their cooler as to pull out a cold beer out. I forgot what I said exactly but it was something like dry ice will keep your beer real cold. LOL Although I have heard of a few West Coast teams playing with it at Indy these guys were from my Div. Division 1.
