Bleh... The website says nothing and shows nothing about their product. There is no close-up shot, cut-away, or detailed product picture. There is no "how it works" section. It says it is "featured" in five magazines (crappy ones at that) but still doesn't say what is said about them. In my opinion, it is just the same marine exhaust fan you see all over Ebay for a few bucks. You really need one good powerful fan to make an increase in intake pressure in a 3-4" diameter device. The "dyno test" on the page only shows one dyno run. It doesn't show a before and after. There's no way to tell the supposed increase in power.
Someone took a classic Ebay scam and made a legit (looking) website to sell the products. Any competant marketer would have far much more information on their product than this one on a far better website.
Waste of money if you ask me. Sure it may increase a few ponies, but not $100 worth
