Professional Transmission

Puerto Rico has a secret that's about to get exposed. Three of the fastest drag cars aren't racing at Pomona or Daytona, they're on a strip near San Juan. Three gems of drag racing are setting records and getting international recognition. See Sakura and Worlds Fastest Rotor Engine for the other two.

William Rojas is driving the Professional Transmission Pontiac Trans Am to wins in Puerto Rico and is now making noise in the U.S.  Rojas is the first Puerto Rican to qualify for an IHRA championship.  The purple bullet ran a remarkable 6.41 sec. ET at 217.48 mph.  If that wasn't good enough, Rojas managed to lower that ET to 6.37 while competing on tracks in the U.S.  The car uses AMSOIL Synthetic 10W-40 Oil in the engine and AMSOIL transmission fluid.
