Here's my Dyno Chart, you can read at the bottom what nitrous can do.. allbeit for only 8 seconds at a time. But hey, thats long enough to make a modded raptor and most 250R's cry.

Stock Piston
Stage One HotCam
FCR Carb with a 142 Jet.
15HP Boondocker kit.

You can also see this chart on the Boondockers.com website.

The top graph is HP, Notice that is peaks out at about 6,000 RPM, then begins to drop off slowly.

middle graph is fuel Mixture (note the FULL RICH spike right at the start... this is an un-modded FCR carb) The note at the bottom show how mant turns out I have the mixture screw on the nitrous system... the further out, the LEANER it becomes. 3 turns was just abour right. I was able to run the bike in a slightly-rich state to keep it safe.

the botom is torque.. max is at 4000 RPM.


Also, note the temperatures at the bottom... it was over 100 degrees this day!
