Could you find the thread and post it? Was it on this forum?

Without reading it, I can't understand how it would add drag to place the exhaust in the wake of the vehicle... doesn't make sense to me without numbers to back it up.

I'm not doubting it, just questioning it, since I haven't seen their testing or results personally.

If I correctly understand the air amplifier thing, you're basically stating a form of Turbocharger, no? Uses small amount of airflow to create a much larger flow of air through induction?
