All I can do is speculate as I haven't tested the two on a sr16. But I think the two will be almost equal until 7.5k ish then the N1 will take over, the regular 16 will start to drop after 8.2ish. And the N1 will keep maiking power up at 8.5 and on. I think the higher quality and better the header is the bigger of a difference you will have betwen the two profiles. The N1 will have a larger, better power band as it will hold power longer...
Edit lol. Don't kno why I thought u were talking about on a 1.6 motor. Just drop the rpm refrences and the same is pretty much true. My expierence is that the sr16 cams are awesome and will do just as good, but will drop off a bit sooner. But once you have a good header you can take more advantage of the N1s. Still the 16 cam is great, Idont think ppl understand how good it is. They just assume the N1 is sooo much better
