Ditto on Jeff's remarks.

Also, some of those guys you see with fans front and back are creating more of a problem than they're solving. The key is to get the air flowing through the core, not around it. If not properly spec'd those fans offer more of an obstruction. Most people would be better off making sure that as much of the air that comes through the grille (not exactly an issue on your car) is channeled through the core. That's what all those sealing strips around the side, top, and bottom of an OE system are for. Secondly, a good shroud around the fan, with just a small amount of clearance to the blades and coverage out to the edges of the core, will help the fan pull the air through (most of those double fan systems you've seen probably didn't have this). And then you need to give the heated air a place to escape the engine compartment. That's a big part of why the lower part of firewalls slope away, to channel the hot air out. That's a large part of why the older cars with completely, or nearly so, firewalls have the hood side louvers, or some run without hood sides. That's why the "smoothie" look has been hard on keeping the early "square" cars cool.
