Has anyone tried them at all?How about with dry ice?I have had one for years but I never did a good test with it.I have put my gas cans in coolers of ice and it seems to help.I wanted to give it a try later on,I wanted to see what anybody thought on here.I want to get this thing in the 5.50's in the 1/8th when it cools off.

Thanks for the input

Later

They help, if the set up takes advantage of the denser charge.
All the class' I've ever ran didn't allow them. So I have no personal info.

yes they work..but I'd only use dry ice.. you don't want it leaking on the track..cause ya know it will. lol.

They work fine but are a PITA and not allowed in many classes. Cool gas is always better than warm gas. Back when I knew guys running stock they'd cool gas prior to a run in hot weather if they had competition or were trying to run fast as possible.

Why would such a seemingly trivial thing, be disallowed???

I totally agree. How much do they help in the heat? I might try one. I run N/A and need all the help i can get.

I was thinking about this last year. The majority of the "cool cans" out there use very small line (I think 3/8 is the largest). I was thinking of fabricating one that would work with -8 or -10 fuel line with AN fittings........ but haven't done so yet.

morroso has one with 1/2'' line, alum can cork lined with a lid.
at least they did back a few years, leaked a bit over time hence the use of dry ice is needed.

 

[Radical540]

Really? I didn't know that. Though, 1/2" would only be -8, which is pretty much too small for a 'supply' line for most....

I'm still batting around the idea of making one.

 

[hammered54]

I dont know, 1/2'' should be ok from the "can" to the carbs after all most carb set ups are -8, run a -10/12 from the tank to the can and -8 from there.

Cooling the fuel made it harder to detect "additives". First banned in Pro Stock. Cooling the fuel is definately worth some power.

L-A-M-E!!!

Radical540, are you discounting what I am posting on here?

 

[Radical540]

Not in the least....I just think the rule is outdated and lame.

Ok, that rule was implemented when people were using P02 for an oxegenator. It was easier for tech to just ban the cool can. Now there are additives specific to fuel that are being used that are even harder to detect.

I tried it on a very hot day. and you know what?? Same ET!

I had a 5 gallon aluminum fuel cell. I laid 3 bags of ice on it. The cell was ice cold. Car ran the same. In theory it seems like cold gas would create a denser charge. But I noticed nothing

I think your fuel warmed up by the time it got to the carb. I'd try it further up stream unless the 5 gal was mounted up front.

 

[RUN-NE1]

I'm thinking part of the gain is the fact you are cooling off the carb and part of the intake especially if you are using dry ice. Hell just put dry ice on the intake and carb no cool can needed. LOL

I am sure it got hot, but not for awhile. The cell was ice cold. The gas was ice cold.The engine was cooled down to ambient temp and was towed to the line. We had bags of ice on while waiting in the lanes. The fuel pump was not turned on/car was not started until we were in the burnout box. The gas entering the carb had to be ice cold. But no difference from the first pass, with no specialized cooling

Did you know Reichert was cooling the fuel in his A/Fuel dragster?
