Advancing the intake lobe on the cams to 106-108 seems to be a serious boost for the the 2500-5500 matching powerband of the PI intake. I have not found a single off the shelf cam anywhere that did this for the NPI head. It is very different from the stock NPI and PI cam specs as its about 9 degrees more advanced on the intake lobe and we are basically keeping the exhaust lobe near the same location. This also lowers the LSA which is another boost to the 2500-5500 range. I should have some more tests in a few weeks of the Stage 2 NPI cam."__________________</blockquote>
