Sure wouldn't want any facts to get in the way of ones imagination now would we?! 
Lets see:
Vettes are notorious for hot engine compartments, poor heat dissipation, and Overheating! Based on Pauls comments, it seems he expereince similar....to the point he thinks he has TOO MUCH cool air in his engine compartment? Maybe in colder climates there could be such a thing.
Anyway, to me there are several outstanding factors to this conversation:
1. the WOT only activation makes little sense and does make one wonder why they bothered.
2. Having the Cowl plenum open 100% with the air cleaner seal in place and sealed is going to force the air into the carb, which was the original objective.
3. IF you remove the air cleaner seal, I believe there are two benfefits; At idle heat will rise and dissipate out thorugh the open cowl vent. At speed, cold air comes in thru the cowl, and creates a vortex when combined with cold air being sucked in from the bottom. More cold air in the engine compartment = less hot hot everwhere else.
Anyway I choose to take my results for that they are, (imaginitive as you think they may be
) whether or not they work in anyone elses imaginations!

It was 28*F this morning BTW. Cold air induction is working fine.
Heck we can have a little fun here at times. I do admire Corvette enthusiasts who do more than me (I just drive) to take their engines to the max.
