I plan to seal the 1" gap between the radiator and supercooler this month. A racer at the track this weekend told me it cooled his IAT's further and gained him 10 hp. That's a good enough endorsement for me to pull the nose and try it. Here's how mine looks. The picture is large so you can zoom if necessary. You can see the damage from the rocks but don't freak completely, a lot of what you see is goo from the blue tape from the track day on sunday. I'm on the stock I/C pump.
