These have to be backed up by hard testing on a test track.

Just googled it, it does look a good core compared to the rest!
I agree with the quick dyno sweep, imo they are a waste of time even for power runs...they need to be held so air temps rise and give a true reading and for info like AFR/Inlet temp/Detonation (if at all).
Subaru intercoolers have a denso core which is also pretty damn good, no idea if it can be bought or what though...A friend has had 8 subaru IC's welded together to form one err huge IC, can't wait to see how it performs but it should be good!

you'd measure inlet and outlet temps, hold it flat on as much boost as you can/are going to run (id imagine) and see how much it actually lowers temp flat out, obviously you're trying to get as close to ambient temp as possible, the closer it is the better.
