has anybody tried slapping on a radiator fan on the back of their intercooler and have it running all the time wit the car on???? i just saw a pic of it and it never hit me like it would work.

 

When you do the math, even a high-cfm fan will be virtually useless after you hit 30mph. Since you don't put any energy into the fmic at idle, there's not much need for flow at that speed, and the speeds at which you do produce boost, you're already flowing much more than a couple of very high-amp/cfm fans can.
