The old rules of racing are being challenged as cleaner and more efficient automotive fuels find
their way to the track. Project Green, a group of researchers from the Department of Energy’s Argonne National Laboratory has found that modern fuel-injected engines powered by E-85, outperform the same engine with a carburetor and leaded racing fuel. The cleaner burning fuel injection engines have been replacing carburetors since the 80s, except on the track.
“The testing disproves two widely and firmly held beliefs in the circle track racing community: that carbureted engines are inherently more powerful than engines equipped with a fuel injection system; and that E-85, which is less expensive than leaded racing fuel, is not well-suited as a fuel for race cars”, says Forrest Jehlik, principal mechanical engineer at Argonne’s Center for Transportation Technology.
