Thanks fellas, for the honest replies. You guys are really full of information, brilliant forum, with brilliant people with the know how, you geeks, just kidding, thanks to all again. you saved me from making a bad mistake. Just hope that one day I can afford the proper supercharger, when one comes up of course, they are so rare and hard to get hold of. Just wish I invested in one a while back when they were going for £1800, I think from prolex, maybe wrong, it was a while back, damn.
