Questions for centrifugal blower guys

Yeah, I was just thinking a brick of an intercooler up front might heat things up a bit, though the car doesn't seem to be having too much trouble as is. I figured I would probably end up buying a blower carb instead of messing with what I have, so could I expect it to be sealed up good or would I still have to think about checking it out? I know some about the water and meth injection, though it would be nice to not have to worry about keeping a tank full since the car would see a lot of street time and only occasional strip runs so it would be nice to have the benefit of an intercooler all the time.
