Dry Ice in your fuel cell? - Page 3

I think you need to back the timing up a couple of degrees with C-25, and jet up a size or two. Someone may correct me. I purchased two cool cans from a custom builder that you freeze a 16, or 24 oz. beer can filled with water, then slide it down between coils, and fill with water. Don't know if it works, but it looks cool.

Someone mentioned cool cans. We used to use them, back when my hair was still brown. I used dry ice and rubbing alky in mine when I had my Jr Stocker. If you have any water in your fuel, you will find it. Freezing it in the fuel line up once. LOL

We can't use cool cans like we used to. I was told there can not be anything in it to cool the fuel while going down the track. Only before the run. Makes that pretty useless. I guess an EFI car could run the fuel pump to circulate fuel through it and back to the fuel cell because of the return line they all use. Then dump it. Dry ice is "before the run", but I don't know that the oficials approve. As mentioned, guys I have seen doing it don't put the cap back on too quick. A fuel cel is vented, not a fuel jug.

You know something Ed, I may have been illegal using a cool can then, but no one ever said a word. But, in back to back test runs, we never really seen anything. What I did see at Bethany was if you laid bags of ice on the intake between runs, there was a much as .03 in it.

At Indy a few years ago. I saw some superstockers during class carrying fuel jugs with blankets on them. Went over and saw the moisture on the outside of the jugs.
It seemed hush/hush but I Added 2+2. Seemed like a great idea. Especially with fuel injection (injector about 3 inches from intake valve). It has to cool the incoming air. My air temp sensor is way ahead of the injector (so ambient air), so I don't know how much.

Was worth a couple hundredths on my old '56 Chevy, and the next car, 250 hp 327" '65 Chevelle. My C/SM Camaro didn't seem to care.

Not something as easily applied as dry ice. I still think the cooling of the fuel outside the car is the best option overall. Heck, just setting the fuel jug in a cooler with ice/water is a step ahead.

Here's a company I found in the back of the national dragster.

If you try it you better have your fuel cell well vented.

The rulebook says a cool can is legal in Stock and SS. It actually says, "One cool can permitted."

Wet towels, bags of ice, etc must be removed from the intake before a run, but a cool can is allowed to still have ice in it during the run. I was told to just make sure it does not leak water out of it.
