Tri"!!' THERE'S NO BAD MECHrn WAY TO BE BLOWN
"Big Daddy" Don Garlits ■ had an extremely successful career in Top Fuel, using Roots style blowers with nitro methane fuel almost exclusively. Big Daddy is still at it, making exhibition passes in one of his early "Swamp Rat" diggers as recently as the Mopar Nationals.
This front engine dragster with dual blown Hemis was for sale at the Mopar Nationals last year. We're not sure if it was a replica or the real deal, but it demonstrates the common use of blowers on Hemis, in this case two of each, during the early days of drag racing.
► This diagram shows the various types of superchargers, or blowers, designed over the years. Today nearly all popular automotive superchargers are Centrifugal, Roots, or Lysholm Screw designs.
