Pulley is set for 10 psi based on a stock setup. If you want more I have a pulley that is 15% reduction and should give about 13 psi (based on my current JCW mini cooper Setup). What do you have for turbo parts?

ON a miata? BS. the stock Mini M45 pulley is 65.5MM and crank is 140MM
even with the 62.5MM nose pulley and 150mm Crank pulley you wont hit much past 8.5psi AND you will be overclocking the SC in the upper RPM band while getting some belt slip...
Might be different on a MINI.

On a mini ..... I'm pulling 13 psi (peak) on a stock sized crank pulley (lightened) and a 15% under drive pulley. I have 03 JCW mini S I also have a bigger intercooler and a cold air intake and Detroit bypass value installed along with JCW head and exhaust. No belt slip here
