Why not mount a fan inside the "cooler scoop"? My SC never overheats when I'm moving, but when I'm stuck in traffic the cooler scoop is havin' a siesta.
As for the cool collar, I can't afford the loss of power. You see the cool collar dissipates the heat into the engine compartment where the air is superheated and expands before intake. This hot, lazy air produces less combustion in the cylinder. I have calculated a net decrease of around 0.03 HP (at the crank).
