The early torque is certainly the *everything* killer. Stock rods, transmission, clutch, etc. I'm currently limiting power output on the low end to protect my transmission or it would probably make 1200ft/lbs peak.

Right, I also hope the Carrillo's will hold it in time.
In the other hand, what a great feeling enjoying early torque!
When I test drive friend's F12 or Lambos (N/A) they feel slowww...

1200ft/jbs
What about your turbos? (size, flowing rate)

I'll be posting about the turbos pretty soon but they are 65lbs/minute of airflow each.

Ok, mines are rated 57lbs/mn.
For reliability boost target is "only" 1.65-70Bar (24psi), reached at 5200rpm with 1.4Bar (20psi) at 4000rpm and 1Bar (14 psi) at 3000rpm by cold weather (<10°C).

For such torque you may run at least 30psi?

Yeah around 30. I am watching turbo shaft speed more than boost though. I'm not really sure how high it was when I was running the car this weekend, I need to look at the logs.
