if you look at area under the curve the power diffrence is huge. I know you guys have a rev limit at 8600 RPMs and you guys shift at 8500 RPMs so I can only imagine the power diffrence to be very very large up there.

What is the set up on the motor?

Mods?

Exhaust?

Who did the porting and how was it done?

Peace

The cam switch point on the ITBs is way to lowat 4800 RPMs. It should be 5300 RPMs


The same thing for the N1 cams, you have it set at 4800 RPMs, it should be 5700 RPMs.


Can some one fill in what the power band would like like if the switch point were made at these points.

I agree the cam switch points seem to be all wrong. I think 5,700 rpm for both setups looks to be best though if I could be so bold as to disagree with you Dre on your first recommendation. I don't know what the N1 cam low lobes look like on a dyno sheet though (pure low lobe without switching ever), so I could be out in left field.
