Some things never change- - - -they just come up with new names. In the early 1950's the dirt track race car Dad ran used a sealed 8-gallon stainless steel beer keg for a fuel tank, and air pressure to force the alcohol/peroxide fuel mix to the carburetor. They ran about 10 PSI in the tank, which was enough to last through a 25 lap main event on a 1/4 mile track.
