Just to give you an idea of what I'm using:

46/28 = 75hp
57/33 = 125hp

An easy way to tell how much HP You're using: 100hp = 1lb in 10 seconds, or 0.1lb/sec.

I use 0.20lbs/second, which gives me 200hp. I have a timer which goes on when the bottle turns on, and I always weigh the bottle after runs at the track.

I would not trust some of those numbers. On the one hand, they're telling you that a 46 N2O jet gives you twice the HP of a 37 jet, when the 46 jet is only 53% larger in area, while on the other hand they're also saying that a 61 jet flows only 50% more than a 46 jet, yet it's 75% larger in area than the 46 jet. That's total bull.

If you really want to know for sure, put your bottle on an accurate scale, attach the nozzle to it and open her up for 10 seconds. Take the weight in pounds that it used up and multiply by 100. This will give you the actual HP you'll get with that jet and the proper fuel jet.
