By no meas is the 3.7 a big torquey motor, but it does offer good torque down low and the gearing puts it in the meat of that torque pretty quick. So, to maintain a level of traction and control the centrifugal is the way to go in my book.

You are right and I happen to like the way a centrifugal S/C makes power. But in most cases in a stop light to stop light situation positive displacement blowers win.
I guess it all comes down to what you are going for. Sometimes the lack of tractability is what is fun. I like having a car that can get squirly in 3rd or 4th on the highway, it doesn't make for good times around the track but it does make for good entertainment.
Actually the thing about the GTM S/C I like the most is the use of the Rotrex. It seems like it might be a good balance between the two.
