    Why do you need an intercooler for a supercharger?

    Increased thermal efficiency (i.e increased power output, reduced knock sensitivity, etc.) - just like the OEM LSA and LS9 engines - factory superchargers, with factory intercoolers.

    I understand what an intercooler does and why you'd need one with a turbo as the turbo heat soaks the intake charge. Cooling cold air seems futile to me lol.

    That is just it - the air stream coming out of a supercharger is not as cool as the air going into it. Ever notice how the 80 gallon tank on the compressor in your shop can get very hot to the touch when using multiple air tools ? It is not soaking up any heat from anything - mechanically compressing air causes its temperature to increase.
