Intercoolers make no noise, and the intake does not make noise either. Turboes and superchargers make noise when spooling up, which can be characterized as a whine on a roots-type s/c, or on a centrifical s/c or turbo, it's more of a high-pitched whoosh. If you're thinking of a "pfft" sound, that is from a Blow-Off Valve, which bleeds off air pressure when shifting so the turbo doesn't slow down.
