50, 85, 100, 120?

Here's 2 charts, one from NOS, one from some site I found a few months ago. Both of these are for dry.

NOS Manual

N20_______Approx HP.
32________50
34________60
36________70
47________85
63________120


Other Site:

N20_______Approx HP.
34________40
37________50
38________60
41________70
44________80


Here is my estimation, based on some interpolation of the numbers from both sources and the shot 12sec used for his 120hp, from 40 to 150 hp, based on a best fit. The curve may start to deviate on the top end a bit. I plan to move up through these ranges as long as I can continue to tune the car to maintain the a/f ratio.

Jet_HP
34__40
36__50
38__60
41__70
44__80
48__90
52__100
57__110
63__120
68__130
74__140
81__150

The ratings should be similar for various engine sizes. A specific amount of nitrous and the corresponding amount of gasoline should produce similar amounts of hp no matter how many cylinders or displacement of those cylinders, when it is introduced via a single jet in the intake stream. As long as the correct ratio is maintained and the mixture is fired completely.
