I am thinking about buying a powerdyne supercharger for a 94 gt mustang that was upgraded to a BD-11a. At 8psi what size injectors do i need and what size fuel pump. Do i need a MSD timing retard too?
If your set on getting that powerdyne then I would say that you could get away with your stock 19lb injectors as long as you had a good intank pump (at least a 190lph version if not bigger) and possibly a pusher pump (like a vortech). If the powerdyne comes with an fmu then use it as well.
Put it this way...you can never really get too big of a fuel system.
