This is going to go further than initially planned, where originally I just wanted good stacks to aid airflow I have been perusing over some datalogs and realize, our intake setup is very lossy and leaves a lot of power on the table.
Vacuum at WOT shows there about a 1psi pressure differential between atmospheric norms and the pressure just after that throttle blades, that amounts to about 13whp on a RAMAIR and CES equipped bike if that 1 psi drop could be countered.
Initially I was thinking about a legit ramair setup that resembles the OZclaw, but working it to fit a good foam panel filter and 2" stack. While that would flow incredibly well, and certainly give the power back, it would only start to give back around 50mph, and would need about 130mph to really give full 14.69 psi at the throttle blades.
So what's better and isn't speed dependent? Ramair + Heimholtz!! RPM targeted reflected sonic wave that can force air into the chamber, and with a ramair setup we could definitely see greater than 100% VE filling at the sub 100mph area.
Still have, lots of work to do, and this intake might end up looking all kinds of crazy, but, in the end there is potential to pick up 15-18hp peak at 6k RPM, and a good bit of midrange as well. If I can nail it down, it would mean 180whp is an intake/tune/exhaust away from stock.
More to follow.
