Features VINTAGE SPRINT CAR PIC THREAD, 1965 and older only please.

  1. If that car once had a V-8, it wasn't a V8-60. It's a sprint car which would have had the bigger 85hp V8.

  3. Well that's a damn shame. I ran my midget there many times with WRA. Perfect size and shape dirt oval. It will be missed. :(

    Jets are actually sized for the max fuel requirements at WOT, which are even richer than the numbers 28dreyer quoted, which are the ratios for a stoichiometric mixture. WOT mixtures need to be even richer than that. For example, on gasoline if the stoich ratio is 14.7:1 the leanest fuel for best torque (LBT) will be around 11.5 - 12.5:1 or so, depending on factors such as manifolding and fuel delivery design.
    Here's a couple of handy charts that you can use to get a relative idea of the amount of different fuels required, and the heating value of each.

    BTW, check out the stoich values for nitro!
    1.7:1
    And in a T/F motor the mixture could get as rich as 1.1:1 to prevent a meltdown. Reminds me of the comment a fellow drag racer said to me, "Sonny, if you see the flames disappear from the headers during a run the engine is going lean. DUCK!"

    Just to be clear, I did not author the paper which shows the racing fuel data.

    I love this, any chance of getting a higher resolution scan... Please. My old eyes are having a bit of a problem.

    I came across this picture in a "girls posing with cars" thread somewhere and really liked the car pictured. I got lost in the 845-pages of Sprint Cars, so decided to just post the pic and see if anyone has any information on it.
    Thanks all ...
