Default T56 nitrous questions.

I'm considering spraying my 408 M6 car. I've never used nitrous before but I'm curious as to how a few things will work. I understand the window switch wot switch etc but since I'm leaving off a 2 step (foot on the floor) how will that work if I'm injecting nitrous at wot. Do I need to wire something into the clutch or just be careful not to leave off the 2 step at complete wot. Also power shifting. How will that small window of time between shifts where the car isn't under load effect the engine. I only plan on a 150-200 shot to get the car into the 9s and I'm on stock head bolts. Will that be safe. Car is making 571/522 on motor. Thanks

I am in the same predicament with the two step. But you can use a window switch and set it a few hundred rpm lower than when you will shift it. That way you can wot shift with out spraying

If your using a signal wire from the clutch to activate you 2 step you can use the same wire to trigger a relay to interrupt the nitrous. You could interrupt wot, rpm, arming wires. Personally I'd go with rpm I think that way the system stays powered up and is just waiting for the trigger again. With wot input depending if its a rising or falling voltage system I think with falling it would keep spraying because it would be seeing 0v.
