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.

Huh!! you lost me at A) lol

[Ian Hill]

well, you always here of guys doing all kinds of stuff to their car for the headsup passes. i understand the light weight oil, but to all of a sudden start cooling the fuel, or intake would drastically change the fuel density therefore the need for a jet change...

also, B Aceves - you any relation to Mike Aceves from Hollister California? was a good friend i haven't heard from in about 6-8 years...at the time he was very much into drag cars and drag slot cars. i was going to visit California and stay with him, but it never panned out.

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!

[Ed Wright]

It is important. About everybody I know cools their fuel if they have a tough heads-up coming up. Chuck Nelson said not to chill it during a run. I used to use dry ice in the cool can on my '56 Chevy Jr Stocker. I don't have one now, I chill it before like Chuck said to. I have seen the fuel check take a second, kinda puzzled, look at my fuel temp at fuel check, they have never said anything. If they do look at the car, there is nothing to see. I have seen small freezers in trailers, just about right for a fuel jug. I don't have room for one. You shoulda walked through the staging lanes before SS class at Indy. LOL
