I saw this "spiralmax" (www.spiralmax.com) thingy which says it adds between 0-35hp and 32% increase in gas mileage. It basically looks like propellors in the intake. Does anyone use this thing and if so, does it really work? Their website has lots of testimonials and even dyno numbers, but I want to hear it from you guys...thanks.
