Reduced rotating mass WILL show gains on acceleration pulls.
For a better picture of what the over-pipe and header are gaining, they should have dyno'd them after the cat-back, then added the pulley after. So we still don't know out of the second gains how much is from reduced rotating mass cutting losses and how much is the header and overpipe making power. However in June they said they saw 6-7 from the header, but no graph at the time.
I don't think we'll get any better than this from them.
It's sad that it's been dragged out to 4 threads, when all it would've taken was a "Holy shit we forgot the flywheel and pulley were still on!!! Pull the dynosheet and edit the first page!"
when I brought up the potential in the first thread.
Be more careful in the future.
