A GT500 with a KB will make between 750-800 RWHP. Put the same KB on the ZR1 with bolt ons and you will see 900+. TVS is a roots Hybrid.....better than a regular roots but still not as efficient as a twin screw. Like I said- numbers don't lie. But they are what they are. If roots is good enough for you then rock on brotha.....for many it's not which is why they upgrade to a twin screw. Seriously though, if the twin screw ISN'T the difference than why is there such a disparity between an Eaton Cobra and a KB or whipple Cobra- one makes 550 max the other makes up to 800RWHP- I can tell you it's not magic. I'd post those fancy graphs you were talking about but you already said you don't believe them.
I'm not trying to be a smart ass here- why are you so skeptical of the numbers? I know you aren't a Ford guy but they have the most recent experience with bigger blowers from the manufacturer as well as a crazy aftermarket with them. Ask some of these other Ford guys if you don't believe me or KB/Whipple. They can SHOW you the difference between the dyno numbers.
