Cool can??
 

A cool can for fuel?
I see some of "my elders" still using them?
Will I see any improvement with one?

Re: Cool can??
 

I dont see them used much any more. I think its because they can leak.

Re: Cool can??
 

I asked our Div 4 Tech Director, Chuck Nelson, about those at the Tulsa LODRS race. He told me you can have one, but can't have any ice, etc, in it going down the track. Only to cool the fuel back in the pits prior to the run. Has to be gone before the run.

Don't think I need one now.

Re: Cool can??
 

I run one it's worth .04 ( i think their was a stink about dry ice a year or so ago)

Re: Cool can??
 

I don't leave home without mine .You can have ice in it in IHRA. Cool can with no ice is like no cool can at all. I ran mine once and forgot to drain water out of it and got backed off and lost my run. That was my fault and i paid for my mistake. Never had it leak with ice in it.283 was fooled when weather changed so it made it wayyy more consistent and like Greg ,it was .06 faster.

Re: Cool can??
 

I ran dry ice in my old N/S '56 Chevy back in the '70s and nobody said a word. It was worth .05 or so. I understand about the leaking with regular ice. Not sure why they would care about dry ice. If everybody can do it, what is the advantage? It doesn't drip on the track, right?

Re: Cool can??
 

With a small fuel cell there are much easier and more efficient ways to cool the fuel

Re: Cool can??
 

Ding, ding! :cool:

Re: Cool can??
 

Glen-

I have one if you want it, let me know and I'll bring it to BIR.

Please, Enlighten me.

Re: Cool can??
 

Think about this. What could you put right into your fuel cell that's very cold, yet won't pollute or dilute the fuel?

Re: Cool can??
 

Glen, what they are telling you is to drop the dry ice into your fuel cell.

Re: Cool can??
 

SHHH this is class racing everything is top secret 007 stuff.LOL

Re: Cool can??
 

Sorry, but Glen was one of the few who really helped me when I got started.

Maybe I should have just sent him a PM......

Re: Cool can??
 

Are return systems allowed on stockers? That cools the fuel ;)

Re: Cool can??
 

Try this, freeze a coke can and insert it.

Cool the Fuel. I've had my fuel down to 33 degrees in 90 degree weather
You can get quite creative. And still be totally legal. Use your imagination

Re: Cool can??
 

On some cars, the fuel tank/cell is a LONG ways frm the carburetor !

just thought I would mention...
On cool days ( when we run faster anyhow ), say under 70 degrees... cold fuel can actually ruin your tune.
The hotter the weather, the more effective the cold fuel will be.

Re: Cool can??
 

While they look cool, I am not sure how effective they would be. The only heat transfer that would take place is where the can touched the outer edge of the coil. Plus, I have never seen a soda can survive a freeze/thaw cycle very well.

As with old school cool cans, the more contact the coil has with the cooling medium, the more effective it will be. I think that is why you would see alot of the old school racers add ice and alcohol to the can. Ice and alcohol would allow heat transfer to occur to almost 100 percent of the cooling coil.

With that said, trying to cool warm fuel as it passes through a line will never be as effective as just starting with cool fuel in the tank. Which leaves you with two options: icing your fuel jug overnight and pouring it into the cell at the last minute or icing your fuel right in the cell of your car.

Re: Cool can??
 

Yes, return systems are allowed on stockers. But I don't think a return system is going to cool the fuel. While a return system may help from adding increased fuel pump heat to the fuel, I don't think it will have any cooling effect.

Re: Cool can??
 

If you are using ice, what about adding rock salt like in an ice cream maker?

Re: Cool can??
 

You guys do know a lot of tech guys read this stuff, right?

I would not put rock salt in my fuel cel. But, that's just me.

Re: Cool can??
 

Why doesn't one use smaller cooler/freezer packs instead?

Re: Cool can??
 

why cant you just drain the fuel between rounds put it in a jug and pack the jug in ice. before you go up to run put your cold fuel back in the cell.

As far as on the return side I noticed that the fuel in my fuel injected bracket car would get really warm in late rounds. I figure its pulling heat through the alum rails bolted to the aluminum intake. Since nobody makes a cool can cabable of being used in a high pressure system I put one on the return side. Save your money on this idea as it did not even come close to cooling the fuel fast enough to make a differnce.

Re: Cool can??
 

Ed, I think he meant adding salt to the ice in a cool can, not fuel cell.

I realize tech guys read this. Are you saying cooling your fuel is illegal?

The rule book says:
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. 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

Cooling your fuel has been going on forever. And every time NHRA checks your fuel they are also taking a temperature reading on it. If you are any good at it, the fuel is still going to be cold when you do a fuel test, unless you stand there warming your sample.

Re: Cool can??
 

I'm sure that is what he mean, Dean. Should have added a smiley.

I'm not sure what they would think about dry ice. May not care. I would't want to find out the hard way they don't like it.

They looked at a friend's car & fuel system here at the Tulsa LODRS race because it checked too cold. He had not done anything, evidently a mistake or the thermometer was wrong at the fuel check desk.

Re: Cool can??
 

Fuel check valve before going through the cool can and it will not be cold at fuel check.

Re: Cool can??
 

Cool cans no! The vapor pressure of our racing VP is @ 700 degrees f. I can make our manifold an induction heater and possibly vaporize the gasoline to the threshold of a real atomized gas....that is the trick...competition eliminate and pro stock guys should have had they cubic money hands on this a long time ago..I know if I had cubic money like some of these guys you'd have to kill me...I'm talking Hagan industries to the Nth power....can you say out side of the box?

Re: Cool can??
 

Danny, the point I was trying to make was that I believe it IS ok to have your fuel check cold.

The rules specifically state that cool cans are ok, in no less than two places in the rule book. If you are allowed cool cans, how can you not be allowed to present a cold fuel sample? And honestly, on most days, by the time you take the sample, walk over and stand in line with the cup in your hand, the fuel has warmed quite alot anyway.

Re: Cool can??
 

I'm sure I'll get a lot of S**T for this but I don't owe this to anyone I discovered it on my own.
You take Dry Ice and put it directly in a 5 gallon fuel jug with about 3 gallons of gas. Small chunks, no cap as they disapeer you ad more till it gets to the temperature you want.
I though you stock superstock racers would have figured this out yourselves.
I guess it doesn't cost much so it goes below the radar.

Re: Cool can??
 

Question...does it work? I mean real performance on et slip?

Re: Cool can??
 

Buy a little dry ice and try it.

Re: Cool can??
 

You guys need to try that on your car. Get back to us with how fast it is, OK?

Re: Cool can??
 

Art, a lot of guys do that, and have for close to thirty years that I know of.

Re: Cool can??
 

Sure sounds easy to do...

Re: Cool can??
 

What is the temp to shot for?

Re: Cool can??
 

First, I am a bracket racer not a stocker so don't have to play by all your rules.

I run a cool can (acually a small cooler with a heater core in it and yes i did check for any flow restrictions ;) ) on my return line right before my cell.

Did the math and mounting it up front , the cooled fuel only lasts about 100 feet down the track, after that it is traveling too fast for any real heat exchange.

Did more math, with a 8 gallon cell, if I run just the fuel pump (car off) I will get one complete exchange every 3 minutes.

Run it for 3 minutes in the pits, all fuel get cooler, then driving to the staging lane takes atleast 3 minutes, another exchange,cooler yet. Then staging etc , you get the point.

A side benefit of running it threw the system/return is everything acts like a heat (cold?) sink gets cold, fuel lines, fittings, reg, carb.

I raced 2 races, one was great air etc with no cooler. The other was brutal 165 degree track temp in thin air. Everyone else was off by 2 tenths, no B.S. , I was a tenth almost 2 quicker.

Take it for what you will.
