Right now, testing of 15% 1n 10% is happening. Hp gains vs hp loss driving the blower are being evaluated as well as fuel/air ratios.
As far as production goes, any size can be made.
My guess i the bsic package would be a hub and one pulley, size of your choice. Extra pulleys, like a stock size, would be optional.
to change your pulley, once the hub is fitted and the blower installed, you need to release the belt tension and remove the pulley-to-hub screws, a tight, but do-able operation.
