That is interesting about the cold gas but a bit counterintuitive. Did it work? Engines don't burn liquid gasoline. They burn vapors emitted from liquid gasoline. I'd think cold gas = less vapor = a lean burn. Maybe good for for MPG but I'm not sure about horsepower. It would also cause the engine to run hotter than it should which also reduce power output.

I would believe in everyday driving if you get better combustion, I would think you would get some better mpg.

Never said engines ran on liquid gas.....
Reducing fuel temperature will get you a denser air-fuel mixture though the carburetor. Cool, dense fuel will increase horsepower. More horse power better time at the 1/4 mile. All I'm saying there are ways to increase hp and mpg because they have been proven. Not saying big increses like some company states but there is some. Do I ran a cool can in my truck....no for I don't take it to the strip. If I did I would consider it. back then we made these but now buy them from any speed shop online. If you have a 1/4 mile track in your area go talk to some of the guys in the pit and ask them. They tell ya some of their tricks and then some.

i am from those days and what you could do back then does not work now. we didn't have to deal with the electronics of today.

OK let's clear the air here folks.. about cool cans.. biggest use was to keep vapor locak at bay.. hot summer day at the drag strip.. Ed Hamberger who was the national record holder for ever actually built an intake manifold that held dry ice to cool the fuel.. as far as CIA's as long as you are asking the air to be introduced from the engine compartment then "Cold Air Intake" not so much. Chrysler's dyno work in the 70's said you must introduce cold air from the outside at sufficent force to help atomize the fuel mixture..anyone of the folks selling CIA's that can lay claim to proven DYNO charts post 'em up

I have the Mopar performance CAI and it was a waste of money. Lots of noise and lost some bottom end HP!!
