The torque curve that the GTM kit makes looks typical for a positive displacement supercharger and I'm amazed that they are getting that out of a centrifugal charger.
Oh I'm aware of the TQ characteristics with a Centrifugal SC, but was just shocked to see such results from the GTM. Personally, I think the low end TQ would be more fun to have. I mean top end HP is great and all but when you are already at 400+ HP what's another 20 over some serious TQ 500-1000 RPM sooner in the powerband. Thats just my opinion though.
