Hmmm that thing looks easy enough to build. Maybe I'll get on it with a few machinist friends. Throw a radiator inbetween a steel extrention of the bottom of the SC.

And then you have to get new gaskets, longer blower bolts, hoses, radiator, pump, and you have to tear the blower off to know how you have to design the core to make it fit. In the end, it will cost you almost as much as buying one from ZZP, but if you have a Series I, buying one is not an option so you would have to make a custom core. If you designed a core for these, you could probably sell it for decent money if you wanted to reproduce it for everyone. Then you could either sell a kit with everything, or just sell the core and let them get the hoses, radiator, etc.. themselves, or buy it from ZZP.

And the worst part. Extend your fuel rail.

the one the guy has just looks like an aluminum rad but thicker, and it has a wider inlet and outlet than a rad maybe 2 1/2" would that be the water cooled one i didnt see anywhere water would flow through, maybe just pull the air through the fins and cool it that way? but then again wouldnt that just be killing the idea of having a direct flow of air, would the super charger be able to suck the air in? cuz how else would it work? i dont know if im explaining this right but iv seen that setup on turbos

Oh yeah, the Series I 3800'* don't have fuel rails available for them. We have fuel rails on the GTP that don't go over the supercharger. They are the PRJ Fuel Rails that 3800Performance sells, they make it so much easier. Someone should make them for the Series 1. I don't know if those rails are different on the Series 1 then they are on the Series II or not, if not you could probably buy the PRJ'* and make them work, but they cost a little bit of money, when you can just spend a few dollars and extend yours with hose.

I guess I don't completely understand what you are saying, but the Intercoolers are air to water intercoolers not air to air, so you have to have a radiator (heat exchanger) on the front of the car to cool the water also, then you have to run the hoses and pump and everything. I don't think it is possible (well not in a way that is worth the effort) to make an air to air intercooler for Supercharged cars, unless they are Centrifical Superchargers, because you with an air to air you circulate the boosted air through a radiator on the front of the car, then run it to the engine, so you have to have air to water because the blower sits on the intake manifold.
