put the dry ice in a sealed baggie??? might be hard to handle, liquid nitrogen for cooking???, might be able to do the same with regular ice, never thought of it

The carbon dioxide gas has to go somewhere.

does dry ice evaporate or turn into water?

Huh? A cool can is like a chemistry or distillation still, coiled fuel line within a can that allows water or dry ice to cool it, there is no mixing of fuel with anything.

I ran one on the street back in the early 80’s. A Moroso, the fuel line is coiled around the circumference of the can. Regular ice melts way too fast. Dry ice is what you want. Walmart sells dry ice.

Engine masters did a dyno test on cold intakes, cold fuel & it picked up power with very cold fuel

I have heard of bracket racers going through a gallon and a half of fuel in one run. There is no way all that fuel is burning. What type of fuel?

That includes warming it up in the morning, driving it to the lanes and back, plus the run. Obviously less than a gallon to go A to B. Based on memory, maybe 3/4 of a gallon from the trailer, to the lanes, down the track and back to the trailer. Maybe. Granted, I wasn't moving a huge amount of air, making big power or using a big carb,

If the results don't match the theory, change the theory.

i use to count on around a 1/2 gallon per 1/4-mile run bracket racing in SO CA with both race gas and pump gas with the Duster. My current E85 bracket car uses around 3 gallons to warm it up doing 3 laps in the morning in the pits and drive it back after 3 1/8 mile pass at Madras, OR This car is hard to get heat and keep heat in the motor using E85 hence the extensive warming up each morning before racing it  All my other cars got hot a lot quicker on gasoline than this car does, even though it is making a lot more power than the gas motors did

I have to ask a question here.
The colder a liquid is, the more heat it takes to evaporate it. Liquid fuel doesn't burn, only vaporized fuel burns.
If you send cold fuel to the carb, it seems to me you would have to run a richer mixture just to get the same amount of vaporized fuel, to burn.
What happened to the rest of the liquid, unburned fuel ?
This is a different argument from having colder intake AIR, which is already vaporized.
If the cold fuel particles don't or can't absorb enough heat in the few milliseconds it takes to travel from the carb discharge tube to the cylinder,
it won't burn. And it doesn't necessarily all evaporate in the intake stroke, or even in the compression stroke.
I have heard of bracket racers going through a gallon and a half of fuel in one run. There is no way all that fuel is burning. In a race application, you don't want fuel vaporizing in the intake. The vaporized fuel displaces oxygen. You want just enough vaporization to start the combustion process. Here is an article about carb boosters, but later goes on to explain cold intakes vs warm. https://www.motortrend.com/how-to/0511phr-carburetor-boosters-tech/

I've seen that EM episode, you have to take these things with a large grain of salt guys FB is a smart guy but these tests hardly control all the variables etc and are only representative of their one test setup (in this case a BBC with huge heads, a huge intake and relatively short runners). Colder air makes more power, less heat transfer through the intake tract to the air, makes more power. Cold fuel may also play a part, but saying a cooler intake makes no difference is a bit misleading IMO despite what they 'saw' in the episode.

I've literally tried this backwards and forwards on the dyno. I've packed the float bowls entirely with snow and put the fuel can out in the snow in the back of my dyno cell to no advantage. Packing the intake with snow can and will add up to 50ft/lbs at the hit but ,Cold fuel does not make power Cold air does. It does however affect the AFR--which way is up for you guys to debate. Your car went quicker because of 1000's of different variables including the possibility of the cold fuel making the AFR slightly richer/leaner. I wouldn't lose any sleep over it. J.Rob

If the car was on the trailer outside....... wouldn’t the fuel in the cell be the same temp as the fuel in the can?
