    All it does is eliminate the engine driven fan

    that cools the radiator for an electric fan thats powered by an electric motor that is connected to a temp sensor that tells it when to turn on and off.

    Shep has this on his race car...he might be able to give you a ball park figure

    as underdrive pullys....use the engine more to drive the wheels and less to drive accessories like the power steering pump, alternator, fan...

    Some guy on bimmerforums has it. I think gains

    must be minimal at best since you are already spinning the water pump (doesn't the fan bolt onto the water pump shaft?). I wouldn't waste my time with this mod...

    The price is nuts -- a similar kit for the B5 S4

    is like $200. I know one of the vendors -- and by sourcing the parts for the kit in bulk -- he gets his costs down to $90 or so (the fan itself is like $12). $650 for a electric fan kit is crazy -- unless there something really sophisticated about the kit that I am missing.
