UPDATE: Knock on wood, running strong. I've logged:
- 47 total 20-25min track sessions (about 16hrs of 'racing')
- 6000miles on the setup
- Not a single launch, not a single drift, not a single clutch drop, not a single burnout. Not willing to add extra stress.
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.
