    the old setup had the turbo feeding the supercharger which blew the seals on the turbo cause it was basically pushing against a brickwall. it was also rusting badly, wiring was a mess, v-clamp was leaking...

    Ahhh. That kinda answers my next question as to why I was looking at two airfilters. I understand the s/c is on a clutch, but which one is being fed boost now? If the s/c is breathing through a filter and the turbo is also, at what point and how is boost from one system "switched over" or merged with the other?

    it is based off of the vw system....the sc is feeding the turbo and the fitler by the turbo has a one way valve inside the piping so.....

    when the turbo starts trying to pull more air than the sc is feeding it, the one way valve opens and lets in fresh air. right now im talking to my sponsor about getting the NST pulley kit so that the sc pushes even more boost. basically, the sc is taking care of turbo lag

    Ahh ok. So the s/c is more of an auxillary unit to the turbo rather than having one compressor feeding the other all the time. Whereas the old setup was a compound boost system. Were/are you using a anti-surge turbo compressor housing on the previous setup?

    well the sc will be going all the time, it will just have the fresh air to help it when it isn't enough. as for the anti-surge housing, i have heard mixed reviews of them so i stayed away from them. i wasn't really sure about it
