That being said, most people who supercharge the E46 330 also find that the clutch held up pretty well. I'm new to the Z4M world, but I suspect the VT2-500 kit is making more torque that the forced induction kits produce on the 330.

our box is of getrag origin but is indeed the same one found in the 3.0l z4 with slightly different internals, the part numbers are different, the z4m has the exact same clutch however as the e46 m3 with a lower spline count in the middl centre piece.... the m3 clutch is a good unit..... in vt2 spec the highest Tq ive seen from these centri blown cars is still pretty low, thats one of the reasons i went for the ess kit as power delivery is stock just a few notches up the graph.... ill go with the HPF clutch thats in development WHEN mine breaks, its a matter of time really.
thanks for chiming in... always nice to have new knowledge on the board.
