my current plan is to go smaller on the SC pulley by 10% in addition to replacing the crank pulley with something about 5-7% larger which will roughly make a 3:1 ratio on the SC to crank
the slight increase in crank pulley should mean no need to change the other drives


and with just the 10% pulley on its own there's no need to uprate the injectors or fuel pump or change the tune although it probably can't go much further
