That is why the transient response between shifts is so good, once they get up to speed they stay spinning.

Rau and Shep are running turbos quite a bit bigger than a T67, their stuff doesn't spool that fast but it doesn't matter since they rev past 10,000RPMs.

They also make dual ball-bearing T67s now for not a huge amount more than the cost of a non-bb T67.

As far as not having to use nitrous has more to do with how high the stall convertor is setup in the car.
