Wow. I think I'll pull the Eaton off my car and get about 10 of those things....
I saw something similar awhile back that said "Its flow a
massive 370cfm of air into your engine." Last time I checked, most 2 barrel carbs pull that much in by themselves.
A buddy of mine bought one just for sh*ts and giggles and couple years ago and didn't tell his wife because he didn't want her to laugh at him and yell at him for wasting 50 bucks. He said it actually made his car slower, like it restricted the airflow. He then invited me over to drink some beers and use it for target practice with his new rifle.
