i can make up all my own pulleys at work thats fine ... I an running a mid range can to suit a supercharger so i'll try 1:1

I ran an s/c 14 at 1:1 on an A14 (With a lumpy cam) and it made 11psi.
I ran An s/c14 at 1:1 on an A15 (with a lumpy cam) and it made 7psi
I ran an s/c14 at 1:1 on an A14 (iwtrh a stock cam) and it made 14.7psi

do bear in mind that my boost guage is/was a piece of crap.

I can get you a bolt on and go A series billet front pulley with blower pulley for $250. (plus postage) The whole thing is modular, so it's no trouble to change the blower pulley. my engineer can make a blower pulley may diameter you want.

hey mate
im running a sc14 on my l18 built by datsport not sure of the pulley size though but could measure if you want
its running about 11 pound of boost
your best bet would be to give baz at datsport a ring what he doesnt know about supercharging datto engines aint worth knowing

im up to buying pulleys for my project but before i go ahead i would like to know what ratio/size pulleys you are running and what boost you get for this set up. also state what engine you have

thanks in advance
