But with me trapping 120mph with my horrible launch and 60ft I'm probably making a little more power than the pistons and rods can handle.
Its hard to tell what kind of boost I was running I'd say around 14-15psi.. I had my boost controller set to 55 duty cycle.. Obviosly too high. I was trying to turn it up to 11 like in Spinal Tap.
The bad part is that I was so worried about getting my car off the track and getting a tow that I forgot to get my timeslip for that third run. Just my luck would be if I ran an 11.9 and don't even know it. I ran a 12.1 the run before and then turned the boost up a little.

Depends on when the engine really let go, if you had your datalogger running you could see exactly where. You will also have to see if it was too much power or you had pre-ignition, so spark plugs first.
Mine runs only 8 PSI at peak torque where the max cylinder pressure is, then goes to 13 at max RPM. If I remember correctly, Turbo's will hit max speed at the peak torque so it might have also spiked the PSI. Engine tear down will tell the story.
