I just read through the intake portion for the 2v... And saw something that is blasphemy. Sean Hyland states: 4-5 HP for a 1 inch throttle body spacer. Is there any validity to this, or should I chuck this book in the trash? Because the world over 99% call them paper weights...and Sean Hyland put they work in his book. Not jumping out to buy one. But plain as day on pages 44-45 he says they do actually add some power. Sorry for my late night rambling, but if there is any truth in his words, that shatters a lot of criticism.
