Highest flowing sbm heads?

This is a very spirited debate for the middle of October. I think we all want 800 horsepower on a 600 horsepower budget but that just isn’t possible. At least on the NA front. I think most of us joke and tease a little to rough up the crowd a little then sit back and watch the show. I know I do. There’s only a few guys on this whole website that I wouldn’t want to sit down with a have a Pepsi or an adult beverage with. So please don’t take anything I say to personal. I really don’t hate Chinese turbo’s. I really only hate their herky jerky staging procedure. Lol.
Everyone knows that and the blow-off noises are the only reason to have turbos!
