"Freezing" gas and going faster...

rixrex's post on Ryan's "first time drag run" thread got me thinking. Anyone else ever make up a tank or "radiator" to cool gas on its way to the carb? Sounds like a *****in' idea.

yeah, they call 'em "cool cans"

 

Very cool...any danger running them on the street in a normal application? (no ice). Could it actually heat the gas if run without a coolant or cause stumbling because of the added distance te fuel has to travel? Thanks,

They ran cool cans for the last 40 years or so I would say

 

Might be a bit of a chance for vapor lock, due to the extra length of the fuel line. Shouldn't be a biggie though.

You can build your own or buy one outright, they do wonders on some applications, not much of anything for others. Cooling the fuel enables you to pack more of it into the air flow, so if you have a rig that tends to run lean when she's hot, it's very useful. Adding a non-metalic spacer under the carb to reduce heating of the carb itself helps as well.

Moroso sold one that was a coffee tin with cork insulation, about 3' of aluminum fuel line, and a pet**** to drain the water. they still make the nicer model that is a blue plastic with a heat exchange core in it, look up part number MOR-65125 on Summit Racing.

I ran a cool-can on a car I had that had issues with long summer trips up I-5 in central Cali. I'd drain it & fill it with ice every time I'd stop for gas, worked great. Before, with the outside temps over 110*, I'd top out at 75-80MPH with my foot on the firewall. After I could cruise at 80 at 1/2 throttle & still have some decent pull when I needed it, made a HUGE difference in power and mileage in that situation.
Never had an issue with vapor lock when I was just toolin around w/o ice in it, but I'm sure someone who has worries of that could rig a byp*** line, or at the very least use heat shielding to insulate the lines (I did this on my cold side lines to keep the gas a cool as possible before it hit the bowl).
