Corvette Enthusiast (my favorite Vette mag) has a good article about C2 and C3 cooling systems. One of the things they touched on is electric fans. Here is their take, "What about aftermarket electric fans? Unless you get a really well-engineered dual-fan setup with a full shroud that covers the entire face of the radiator core (with pressure-relief flaps for added ram airflow at highway speed), they're a poor substitute for the factory fan setup, they don't move anywhere near the volume of air the fan/clutch system does, and they place a major electrical draw (30-40 amps) on the system at the worst time, when the alternator is at its lowest speed. The typical single round aftermarket fans that attach directly to the radiator core only draw air through the portion of the core that's enclosed within the diameter of the fan blades. the other 50 per cent of the face of the radiator core gets no airflow at all. The factory shroud ensures that air is drawn through every square inch of the core, all the way to the corners."
This is something I have believed for a long time. Electric fans aren't worth all the expense of the conversion. So why is everybody going with electric fans?
By the way, you should read the whole article - lots of good stuff.
