Nobody is bashing your idea, its just cooling a 600HP rotary and cooling a 600 HP piston motor are TWO different things entirely.

The rotary has no wasted stroke, and generates WAY more heat.

 

Mazda went with a smaller cooling system in the FD to save space/weight/etc and look what happened

oh and I've never had a problem with the stock N/A cooling system. Even taching 5000+ for 25 minutes at a time it never goes over 210.

 

Im sure mazda thought about this and must have found that using a larger radiator, that wouldn't fit verticle and only at an angle would be the only optimal way for cooling the engine.

 

Yea, but is that EVO a drag only car? If it is it only has to cool for a few seconds of running, then it gets shut down and can cool off. Maybe it'd be ok just for the strip, but not on the street.
