Re: Intercooler (fwd)or 30v A4 supercharger kit

Haudi,

I've just come up with a new vendor acronym:  "COS," or "crock . . .

The only way these marketing geniui (plural of "genius"?) can get away with
this is they must only be running a few pounds of boost. The bottom line is
that compressing air--in any fashion--heats it. A turbo might heat it a
teensy bit more than a belt-driven supercharger, but that doesn't make the
SC "cool."
