It looks like a good idea, my only question though is where will the heat go? Sure you can blow air around your engine bay all you want, but if its got no where to escape it won't help much.
At least on the CX7, the engine bay retains heat very well.... TOO well. After a driving home with IAT's in the 120-150F range (engine bay temp) it will seriously take 4+ hours to cool down to a reasonable temp if you park in a garage and leave the hood closed.
isnt a bad idea if it works...
I had dual puller fans on my MR2.
They were a bit on the loudside, but functional!
That's HOT!
