    so, i want to open this back up for dicussion......
    if i wanted to purify nitro, say, seperate the alcohol, how would i do it?
    if i froze it, or got it below -25 would the alcohol rise to the top?
    would it give me 99% at the bottom where my pump picks it up?
    so, could i run as well on 94% as i did on 96% as long as i freeze it?
    could i maybe run better on 97% than i did on 98% and still the same on 96%
    as long as i worked on my 99% tune up?
    seems to me, if we all worked with the same percentage, we would have parity.....

    chillin nitro

    Nitromethane freezes at -29 degrees C, while Methanol freezes around -94 degrees C.......So yes, if you were able to chill the fuel, the alcohol would rise towards the top, and the now much-higher nitro percentage would feed you fuel pump, therefore giving you a much more potent fuel to feed your powerplant......and guess what? When you go to fuel check the fuel would seem weak, because now, the methanol and remaining nitro would be mixed thoroughly, making the "duped" officials unaware of what is going on.

    hmmmmm

    Just a question for you. Have you ever chilled your nitro or do you even use nitro?

    The fuel going in is exactly the same percentage as it is when checked after a run. Take it from someone who has tried it.

    Thanks.

    Dumb Question

    If chilling doesn't affect it in advantage, why does anyone even waste the time, effort, and resources to do it?

    how did you check your percentage at the bottom of the tank vs. the top?
    at what temp did you expirement with. -20's or +20's?

    In the freezing process, are there concerns of "water" being introduced into the mix?

    Sitting still.

    Your theory only works if the engine is not running.The fuel returning to the tank when the engine is running should mix things up in the tank.I wonder the temperature of the fuel as is passes through the fuel pump and supercharger?
    I am sure it warms up there as well?Purly speculation.Then there is the burnout and the brakes after it.Reverse and launch.All create g-forces.Mixing the theoretical tankfull of go fast.

    I do not know why someone has not pointed this out already, I am sure it would not be good TV with out some controversy... LOL
    Heck even when an AFuel car is warming up on Alky, the fuel is circulating so the theroy of having the Alky Seperated and having 100% at the hit is "BUSTED"

    not really...
    i have held my hand on the pump while it was running, it's pretty cold........
    we don't have super chargers, we all know that.
    what i am talking here is not total seperation, i know fuel gets returned,
    it obvisiouly would not flow in block ice form but, the heavy cold nitro would find its way to the bottom, you guys are missing the point.
    30 degrees.....is not cutting it, it needs to be 1 degree above sluge form. so i can sit in the lanes for 45 minutes....
    i tried to give everyone a heads up....
    if MR. Collins wont do anything, i'm gonna load my tow car up with dry ice and fuel and fill my car car up in the lanes when about the third car from me is firing up....
    i can't buy a freezer, it's a six month back order right now.
    i know you played around with this when you worked for tom Will....
    when i worked for him we didn't mess with it....
    i just have a theroy, chime in here, whats your opinion.

    tell me how someone can run as well with 10 year old stuff....
    there are lot of guys that want to know....
    we upgrade our stuff constantly...i've posted stuff here about cams and all i get is cricketts....people are talking about cams, i just don't see it here.
    i've even posted my cam here for starters....nothing...
    i've got a '40 tune up, got a lot more....
    this is all i do, i'm not the master, i've talked to the bull.........
    we lost 2% and we are going to loose the "chill factor"
    things are tough now....we want to go testing, but we don't have the cash...
    so...we test at gainsville...$5000 later...just spent $3500 on new rods pistons and cam.....$8500, is a lot to go sit in the sunshine and drink a few beers.........

    :confused:....I dont know who you are, or where you are for that matter...but where I live there are freezers aplenty. I guess I just cant see there being a great rush on freezers right now as to the stores being completely out of them all at one time?? Thats a hell of a thing to be backordered...lol...:D!

    Caution: Your mileage will vary.:)

    Case #1 -- Summer air

    Altitude 950 feet
    Air Temperature 95 degrees F
    Altimeter Setting 29.75 inches Hg
    Dew Point 74 degrees F

    Density Altitude 3995 feet
    Absolute Pressure 28.742 inches Hg
    Relative Density 88.82 %

    __________________________________
    Case 2: -- air cooled by fuel (Not real air temp)

    Altitude 950 feet
    Air Temperature -10 degrees F
    Altimeter Setting 29.75 inches Hg
    Dew Point 74 degrees F

    Density Altitude -3155 feet
    Absolute Pressure 28.742 inches Hg
    Relative Density 109.56 %

    _________________________________
    Case 3: -- 1.7:1 ratio

    Altitude 950 feet
    Air Temperature 62 degrees F
    Altimeter Setting 29.75 inches Hg
    Dew Point 74 degrees F

    Density Altitude 1941 feet
    Absolute Pressure 28.742 inches Hg
    Relative Density 94.44 %

    __________________________________
    result: -- Best guess
    5.62 increase in air inside engine
    tuned correctly = 5.62% more power.

    __________________________________
    Now the Unknowns:

    What is the intake pressure for each intake scoop from 70mph thru 280mph.
    ( need this data to build a fuel map grid base line. )
    What is the lift drag map for a 2 element wing?
    ( need this data to map tire load so as not to blow the tires off
    before the downforce and traction exceeds engine torque.)
    ( yes I have this for single and triple element wings as allowed by NHRA)
    Which front wing do you run?
    (yes front wings vary in drag by a wide margine)
    What RPM is your cam for?
    (Old school basic engine stuff, but kind of important.)
    (I can't make a 4000rpm optimum flow engine run at 5000rpm like it should.)
    (Remember at 5282rpm that horsepower = torque every time)
    (If you want to make 20% more horsepower, turn 20% more rpm)

    Painful eh?:confused:
