Regardless of where you start with bottle pressure and if the bottle is full I've seen at least a 50 PSI pressure loss by the time the run is completed and I'm back in the pits turning the valve off. It subsequently drops more each pass even at peak pressure when you leave the line. Thats part of the reason some some folks use double bottles to help equalize the pressure. However, as the bottles empty its harder to get the pressure stabilized and you will see it gradually in ET as well, therefore the power is droppping.
Whatever the case, a 200 shot generally from what I've seen does not equate to 200 HP at the wheels. At the motor, maybe. I'm speaking from experience and with a dry shot. I've seen Wet systems put out more power to the wheels but even on dyno's I haven't seen them put that power to the wheels either.
Now a built car, with high dollar wet Port injected system maybe. Again, I'd have to see it and in back to back runs at that on a dyno to prove it.
I'd have to check and see if I still have an old Dyno sheet around with mine.
