Fuel "cool can"
 

I'm sure this has probably been beat to death previously. Has anyone ever done a back to back comparison on using a cool can versus not using one ? Does anyone even make one these days, as I know Moroso has stopped production. Thanks in advance

Re: Fuel "cool can"
 

Canton still makes one but its a little pricey. Over $200 but it does look like a nice.

Its cooler/denser air that makes the HP.

back when dad was driving the car, he was trying to set the ihra record and had I said hey lets try some ice in the cool cans.he said sure go ahead and pour it in... He went on out on the 2nd pass and beat his previous pass by a .10 ;)

Re: Fuel "cool can"
 

Depends how big a electric pump is bypassing fuel which heats up the fuel.

When I had my '56, I was an aircraft technician. I had our sheet metal shop make me a box, mounted next to the front of the radiator. Was about 6" x 12", (not round) with a -6 an fitting (with an -6 an cap)TIG welded on, drained water right through the factory radiator drain hole. Used aluminum tubing, transfers heat better, top flap/lid was on hinges, with aircraft latches to hold it shut. Testing with it bypassed, or full of ice, fuel lines sweating at the carbs, was a solid 8 hun quicker cold. At Fuel Check, near the scales, those old Carter WCFB float bowls would feel cold, and sweating.
People can repeat "only air temp matters", it's another thing Jere Stahl told me to do, and he was correct. I am not the only person having the same experience with that.
I know a fast Pro Stock car that cools fuel before pouring it in the car, and icing the fuel cell.
That was my experience. Right or wrong.

Re: Fuel "cool can"
 

Ed you absolutely correct on this!

Re: Fuel "cool can"
 

I guess this rule pretty much made cool cans obsolete.

General Regulations Section 21, page 5

Fuel/Air:
Any method of artificially cooling or heating fuel prohibited (i.e., cool cans,
Freon, wet rags, etc.), except as noted in Class Requirements. Cool cans,
wet towels, etc. are permitted in Super Stock, Stock, Super Comp, Super
Gas, Super Street, and E.T. classes. Wet towels, rags, ice, etc. must be
removed before vehicle leaves staging area. Coolers, chillers, etc., where
permitted by class requirements, are prohibited outside of the
competitor’s pit. Ambient-temperature air only; cooling or otherwise
changing the conditions of the intake air is prohibited. Spraying of intake
with any artificial spray or coolant prohibited.

Not obsolete, the way I read it.

Re: Fuel "cool can"
 

Rick I think the cool can must be empty before leaving the staging lanes.

Re: Fuel "cool can"
 

I read that as saying the external cooling, ice packs and towels laying on the engine must be removed. I remenber seeing the ziplock bag in the staging lanes with ice meling in them..

Re: Fuel "cool can"
 

Trust me, you can still run a cool can....OR, Throw 3 pieces of dry ice in the fuel cell in the staging lanes and call it a day....Ed Wright, THANK YOU for your reply , heard through the grapevine your jr. Stocker was bad AZZ....

Re: Fuel "cool can"
 

Are there guys cooling fuel before adding to the fuel cell? Illegal? No cool can but cooler fuel?

Re: Fuel "cool can"
 

If you come to Indy and watch class elims you can see what goes on....

Re: Fuel "cool can"
 

Personally, unless you can't make the index or running a heads up race, it's a waste of time. That's what the dial in is for, the more complicated it's made, the more chance of mistakes. Have it there if needed like all the other little tricks.

Re: Fuel "cool can"
 

Personally never seen anybody do any of that for anything but class or heads up.

Re: Fuel "cool can"
 

Didn't the Emmons boys dump dry ice in the fuel cell last year before the heads up with Mr Larry somewhere?

Re: Fuel "cool can"
 

They do not want any water in the staging lanes. Most use ice before the staging lanes.
Go to Indy, watch what goes on just before the end of the staging lanes. Last time there, they parked me on the left side, maybe 50' before the end of the staging lanes. Lots of guys storing their chillers, ice & sprayers by my motor home. I felt very fortunate when the gentleman parked me there.
Dry Ice is all most will take up there. Last time there I had bags of crushed dry ice on my Intake. Ron Terrel still handed me my ***.

Re: Fuel "cool can"
 

Other than a cool can, I was taught to dump 5 or 10 gallons of water through the system (In the upper hose, and out the therm housing, no stat), of a hot engine. (That was good until I got to the semi's and final's and they started rushing me.) It was a heads up or record thing, but I stubbornly did it even bracket racing, lol. That practice was also disallowed, I think mostly, also because of the water that could drip off the engine while staging, etc.

Re: Fuel "cool can"
 

Just thinking out loud with the last part of this rule. Wouldn't cooling the hood or any party of the air that doesn't have fuel in it be illegal? Cooling the intake would be a grey area as your changing the air temperature or are you cooling the fuel?

Re: Fuel "cool can"
 

Cooling the manifold cools the air going into the engine.

Re: Fuel "cool can"
 

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.

Re: Fuel "cool can"
 

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.

Re: Fuel "cool can"
 

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

Re: Fuel "cool can"
 

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

Re: Fuel "cool can"
 

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

Re: Fuel "cool can"
 

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?

Re: Fuel "cool can"
 

Where are you thinking of putting the cool can?

Re: Fuel "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.

Re: Fuel "cool can"
 

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

Re: Fuel "cool can"
 

I meant where would you physically mount the cool can?

Re: Fuel "cool can"
 

in the trunk next to the cell. and the pump. we don't run stock but we do run a local NA heads up class and if its really worth .08 its not that much hassle for the et.
