yeah good call,still want something that's useable on the street,hence why im not bothering with something massive,just got back from a mates whos nearly finished his typhoon and he,s running a gt42r with a 1.22 housing which is going to be an animal on the street,my stalls only a 2800 so will try it first at the track and see how it goes,wouldnt expect to be making much boost at that stage!! thanks lee
