Specialties Performance SVT F-150 Lightning & S/C Harley-Davidson F-150 Blower Crank Pulleys |
 |
One of the easiest things you can do to boost horsepower in your supercharged Lightning or Harley-Davidson F-150 is to change the blower pulley on the crankshaft. The new pulley has a larger diameter, which provides for more supercharger revolutions, and therefore . . . more boost! We installed the 9.75" pulley on our project truck, and in about an hour, our boost had risen from 8 psi to 16 psi. Add the Accufab single plate throttle body for better throttle response too, and your rig will feel like an all new truck!
