The first example is right here, I expect more to follow. Please note, not insane gains OVER a 37R, but power is SIMILAR to a 37R (37R = bb T67 slizang), and torque is much higher, which is what makes this thing amazing IMHO:

"Compared to the "37R" kit that just came off the car it's up 13 whp and 80 ft lbs of torque."
Also of note, this car had the .86 turbine housing on it, and saw no power advantage over other cars with a .68 turbine housing, but spool is ~500rpms later (torque curve levels off later).
...Sorry for saying people were seeing 'modest gains' over a T67, I meant to say modest gains over a standard 35R on par with power levels of a bbT67...
