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.

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.

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.
