this is a very cool project. i had planned on doing this last year, but after all the bugs were worked out, i the supercharger was just easier. i used to have all sorts of data on set ups like this. ill see if i can dig some up. this is pretty much the only way to do it - i just dont see the room under the hood for a traditional turbo and manifold. STS systems are turbos like this and they seem to work fine. there will be a little lag, but it wont be a deal. also, the long charge pipe running under the car acts as a little intercooler as well. i love turbos, but you cant beat the mean looks of roots
