If you fit a 15% pulley you'll see 14-15psi, standard psi is 8-9psi. If you fit 17-19% pulley you'll see I beleive18-19psi which really is on the limit of a standard supercharger. Most poeple that want anymore boost use an uprated version, this make a different sound too.
You can pick up a nearly new supercharger on ebay for aprox £100-£150
