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 Thank you, some data to backup science and logic :P. If it made a significant difference people would be running A/C cooled heat exchangers to their fuel lines, and OEs wouldn't bother with plastic intakes (yes I know it can be cheaper but cooler air is actually one of the primary goals).

J.Rob Same experience here. I don't think cold fuel does much of anything. It makes it slightly more dense and a little less likely to vaporize. If those things add power then that is a clue about AFR and perhaps octane or the type of fuel that your are using. Cold air makes power and cold intakes make power. Insulating the intake with wood spacers can add power. Building a turkey pan around the intake and filling it with ice will add power, intercoolers add power, etc.

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? You missed the part where i mentioned i was about out of fuel

Hey B3, you live in Kalamazoo, what ever happened to Mr. P-body, did he pass away? My memory is fuzzy on that Mike lives over on the other side of the state. But he is fine, last i spoke with him. He and his wife winter down in South Texas, pretty sure they are down there right now. Talked with him back last fall, was wondering how he was doing myself
