Fuel temperatures

[FED 387]

NHRA currently bans any artificial method of cooling fuel in "most" classes now---some exceptions are the ET/Super and bracket categories---so that means no chillers/cool cans/aerosol sprays/ice cubes etc if ya can artificially cool it below the ambient temperature it is not legal--my understanding of the rules---comp

Is this right? I still see lots of class cars with cool cans. I took mine off last year when I was running K, trying to get to minimum. I had plans of reinstalling it this winter. I never recall seeing it in the rulebook.......

From the 2012 NHRA rulebook: Stock Cars: Section 10A, page 4 under FUEL SYSTEM- "One cool can permitted. All fuel system components (regulators, cool cans, etc.) must be installed not less than 6 inches in front of firewall."

Super Stock section says "One cool can permitted." also.

I would think cool cans and things like icing the intake would either A) only work if you do it every pass, or B) only work if your set up was not right in the first place. I an looking for a bracket car type of fix. Run it the coolest way possible as often as I can. I run one to two jet sizes rich all year. My engine smokes on start up in the hot summer I'm so heavy on fuel, but the motor stays consistant. I know if I ever end up in heads up race ill need to rejet , but I am thinking, if my fuel was cooler then maybe I could go down in jet size and still be at the same air fuel mixture.

Wade, our tech director told me, about a year ago, I could have a cool can, but I had better not get caught with anything in it during a run. Could use it in the pits, then need to empty it before running.

If fuel temps are not important then why are the Alky classes limited to a certain fuel temp and why does every PS team chill their fuel? The alky fuel team I do work for has a freezer in their trailer. They keep more than Chicken Pot pie & TV dinners in it. DuH!
