Where to find reasonably cheap supercharger pulleys?

Hey John here. I'm running a C4B with a Whipple supercharger at 15psi. I wanna lower it down to about 12, does any1 have any info on where abouts I could find reasonably priced pulleys?

Thanks mate, surprised on how much gear and the pulleys they got. Going to order 61 mm pully for $97should do the job

Is there any way to tell what size injectors I've got now, because I'm using 32ltrs per 100km and getting very dear to run. Im thinking smaller pully and smaller injectors should help, what do you think? I think it's running 42 pounds injectors. And will I need to retune the car. I think it was set up for E85 not sure I bought the car with no information about what was done to motor. Need help any info would be greatly appreciated. Cheers John

And will I need to retune the car.

Yes. With usage like that already sounds like the tune isn't that great anyway.

If it was set up for E85 without a flex sensor (which I doubt it will have if it's still using the stock VX ECU) then the car wouldn't run on straight petrol.
