    calm down

    I believe what he is saying is that we ALL have ice chests in our pit. You know, the ones that keep our beverages cold.:rolleyes:

    thread record??

    Dave, when you first posted this thread did you think it would get this kind of response? What have you seen with cooling, or do you? or can you say??

    As of right now, this thread is seven 'views' away from being the most viewed thread in the history of the site.

    Last year's thread in regards to helmet shrouds, seat inserts and belly pans was the previous most viewed.

    Will, that statement about cooling fuel in the rule book could be arguable about it's specific application. All of the rule conditions stated in that paragraph where referenced to things that are physically attached or located within the vehicle itself. I take that to mean you cannot chill the fuel while within the confines of the vehicle itself.
    To expand that idea a little more it states you cannot pressurize the fuel tank. Does that mean that all of those vent scoops that actually pressurize the tank at speed are doing something in violation of the rule book?

    Just one that digests the rule book..........blessings...........Ron Clevenger.

    clarification

    either way, I think NHRA needs to clarify their position on this. clearly, there is some grey area there. (that's an odd sentence....)

    "Spraying of intake with any artificial spray or coolant prohibited".


    So does this mean that blower cars can no longer spray the injector with De Icer?

    i dont kknow if cooling fuel works. we've run our best numbers just dumping it in the tank. ive heard that some "a/fool koolrz" get that stuff to near slush. (that would be an awsome dairy queen flavor) if putting it near an a/c vent consists of cooling than it has not helped me. i dont think it will get cold enough. plus, it hasnot helped my performance.

    will do i get a medal for starting this thread or the breast to pin it on.

    What Chilling Fuel actually does..

    Chilling anything will have the same effect. All chilling does is allow for more molecules to be in a given volume of space. The chilling actually calms the molecules down, requiring less space for each molecule's existence. It actually makes the makeup more dense.

    It wouldn't change the concentration, just the amount needed to fill a volume. Say you fill a 10 gallon Fuel Cell is at 72 degrees, chill it to 30 degrees and it wouldn't look full anymore. As long as you don't hit the freezing point, it's a chemical property of most things that exist as a liquid(or gas) at normal temperatures. Air does the same thing, the cooler it is, the more dense it is, which would be the other effect of having chilled fuel.

    Thats why you should always fill your gas tank early in the morning, cheat the system! :)

    As far as I know, I have no opinion on the rules nor did I post any opinion, didn't mean to piss anybody off, there were just a lot of questions about what chilling fuel actually does and there was no definitive answer left as to what chilling fuel actually does, so I posted one. It's not my place to have an opinion on the rules. Shit, if it were up to me, I'd say F*&K the rules and let 'em eat! I'm sorry the rules are affecting everyone, but don't make me your whipping boy.

    As far as being here to sell just to sell clutch discs, boy I peddle those bastards hard here huh. My sales have skyrocketed since I joined. :eek:

    Have a coke and a smile and simmer the hell down.

    Question for the whole class

    Here's a simple one to start with...

    What pushes the piston down the cylinder?

    (Simplest answer possible please.)

    Flash,
    Is it.................expanding gases? Like when a gas heats up?

    What did I win? :)

    The problem is with the blown alcohol car it does not work. Since that big blower is already overfilling the intake port with air, if you put the cooler (denser) fuel in it gets rich and slows down. It's that old supersonic physics problem.
    As where the cool nitro charge on the normally aspirated motor quenches the cylinder, pulling a larger vacuum and pulling in even more oxygenating fuel and air. Then you add the greater expansion factor and you get 5-teens if you did it right.
    Can I have another pat on the head, Professor Flash?
