Fuel "cool can" - Page 3

Cooling the manifold cools the air going into the engine.

You are sitting in the pits on a summer day. Averaging temps 85* to 95*. Pit surface, blacktop, stone or concrete, has to be 100*+. Your factory tank, filled with gas, absorbing that heat or a fuel cell that's in your trunk. Metal fuel line about 18 + inches from that same ground. Now all that warm gasoline has to flow thru that small coil of tubing and you expect that gasoline to cool down to what temp? Hot cast iron intake and hot engine compartment, that's a lot of heat to overcome plus the gas temp itself by a small cool can. Iced down intake and carb is probably worth more in performance can luke warm fuel. An engineering friend is going to investigate it this summer. I'll post the results.

Your thinking the fuel won't cool down, traveling through the tubing in the cool can?
Cold sweaty carbs might show different? Mine were sweaty & cool to the touch.

An engineer/author has investigated it, David Vizard. After trying it on his own racecar, he recommends it.

Since water runs through my intake, I'm cooling the water, don't know what you other guys are cooling. lol

Outside of the Intake runners, where the air passes into the cylinder heads. Different part of the manifold than where water passes through.

i brought this subject up to my dad and if you do have a large pump like we use a magnafuel 500 that regens alot of fuel would it be effective to put the cool can in the line returning fuel to the cell from the pump and chill the fuel in the cell say if you had a 3 to 5 gallon cell?? also we run on ethanol which uses more 30% more volume would that increase the effects of running a cool can or do you think it would work at all?

Where are you thinking of putting the cool can?

in the bypass line running back to the cell from the pump. so it would be dumping cooled fuel back in the cell.

I really don’t seem to understand unless you were running stock and have a heads up why bother at all????
A lot of hassle for so little gain. and you would have to continue to keep all the variables as close as possible to be consistent not really worth the effort
