The fuel was not pre-cooled and when you finished a heat, the cooler had to be re-filled with Dry Ice. At Depue that year, I won "C" & was 4th in "D", but we couldn't find any dry ice. We just used regular ice, which probably had little effect.
Interesting. I specifically remember someone using it at Winona, MN one year at the Nationals (maybe with a Crescent 500cc ?).
