Recap: Stock 2jz engine, stock GS6-37BZ 6spd, Clutchmasters clutch FX400, Z4M rear axles, 3.64 Auto rear (now with Quaife), Z4 Auto driveshaft.
This power level must be abusive for the drivetrain, and I took a risk in this build not knowing what are the limits of the drivetrain (motor excluded...). I didn't think this would hold 500wheel torque / 600wheel hp for very long, but I'm impressed. (if you go by 15% drivetrain loss, that's 700bhp?)
I'm tempted to raise the boost and make another 50whp; it's that easy. Why? Because I can, because it's fun. BUT - where is the limit? Does anyone have any empirical data on anyone else who's pushed these parts further than I have? Since they're shared with other platforms, perhaps there is info out there.
I'm particularly worried about driveshaft, axles, diff and transmission.

Redneck mathz:
If the stock drivetrain is built for 200,000kms at 325hp. Wouldn't that mean you should get half the life from twice the power?
NOW TURN UP THE BOOST
