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
Thanks for the real world response !!!!
