NGF..not trying to WIN any arguement here...but your still struggling with the idea of HP and its relation to TQ. The #s for TQ and HP will correspond exactly on every single dyno graph youll ever see.

For instance every single car on the planet that makes 200 ft/lbs at 6000 rpm WILL be making 228.48 HP at that rpm. You get the HP figure from the simple equation of 200 ft/lbs x 6000 rpm / 5252 = 228.48 HP. Its as simple as that all HP figures are derived from TQ at whatever RPM its measure at.

So do this as a mental exercise. Get out an old dyno graph or print one from online of an engine you are familair with. Make it a naturally aspirated engine. Look at it....then pretend we are going to add a shot of nitrous at 5000 rpm. Yes that nitrous shot will increase the HP...but what we really have done...is increased the cylinder pressure on every compression stroke which pushes down on each crank journal which in turn increase the TQ output of the motor. So what we have done by spraying nitrous on that motor is increased the TQ. SO on our pretend motor. Calculate how much TQ you would like to shoot for at a given rpm to be increased by the shot of nitrous...and draw a new line. Then...using your new line...find the new TQ number and plug it into the eqaution of Tq x rpm/5252= HP. Do this for several spots over your usable rpm range and connect the dots for a rough estimate of you new Tq and HP lines on your graph. This will also tell you how much you will have to spray to achieve you HP goals.

I personally shoot for a flat TQ line when designing a nitrous motor.
