Probably somewhere between 18-21 psi of boost. You will need to get some aftermarket cooling put in place before the hot summer months come as the 185 cause the S/C to spin a good bit faster. Either go with the Supercooler from Needswings or talk to Eurocharges as they also have an aftermarket heat exchanger.
As for HP bump and such, it varies by car.
