Can they be used im putting a powerdyne BD11A on my 87 GT right now it has U/D pullies will it work or do i need to go back to stock stuff and where can i get the Alt and Water pump pullies?...
will it work.. yes... will it make boost... not really. your crank pulley to blower pulley ratio is going to be screwed up.
Junkyard is where id be getting the pulleys
big stock crank pulley vs little blower pulley spins the blower faster
small crank pulley vs same blower pulley = spins slower
will it work.. yes... will it make boost... not really. your crank pulley to blower pulley ratio is going to be screwed up.

huh? It's a seperate belt for my blower, alt and wp have their own and having underdrives on them have no effect on boost. Crank pulley is the one that comes with the blower. Correct me if I don't understand what you are saying
Does the BD11a use only 1 serpentine belt?
if its a one serp setup a smaller crank pulley would slow everything down including the blower but if the blower has its own pulley set and belt than it wont matter as long as the blower crank pulley will still bolt to the aftermarket crank pulley on your motor.
