Re: broken piston
I would check the fuel pump to make sure it is up to spec. If the motor did lean out when the nitrous was applied, Then that would be a severe case of detonation happening.

Re: broken piston
Forgetting all the safety stuff that is so popular today, even with a full manual control system you should be fine as long as:
1) Your N/A + Nitrous levels don't add up to more than your engine is designed to handle,
2) Your fuel system is such that you have sufficient volume AND pressure, plus of course enough octane, and;
3) You don't get into detonation.

Re: broken piston
I would check the fuel solonoid. It's possible that it may have closed (lost connection, or bad noid, or cloged, or stuck closed) Yor FPSS would not have any way of knowing something like that was wrong. It is very strange, like the other guys said it's not really alot of nitrous and it should not have killed the motor. I ran a 200 shot on a 85K bottom end and nothing went wrong with it (it was only 4 passes but I still did it).

Re: broken piston
It was a brand new kit when I bought it last summer. Why wouldn't the FPSS shut everything down if the fuel noid was not working? I thought that is part of what it's purpose was.

Pull some timing and add higher octance gas when spraying in the future. I am not the best on diagnosing what happened to you previous motor. good luck
But that's just me, others don't feel it's necessary.
