Thanks Stephen...
150 HP range is a realistic number, and it's what I'm hoping for.
I would love to see any dyno plots you might have??
This project started with a ZX-14R header and 1 slip-on, later changed to a ZX-14 Header and 2 slip-on's (w/valve).
That led to idea of opening the left port "only" when I needed the extra exhaust flow...
Gary, a stepper motor and ECU control was discussed on page 1 -3 of this discussion.
Because of complexity, I opted to try a manual operation first.
{to see if controlling flow thru the left aside does anything} {ie; Dyno runs}
Most folks think it is a waste of time..... But, {because I'm hard headed} I'm still trying to get it built...
Grant your a lot more knowledgeable than I about operation of a waste gate etc.
I think my valve is basically a poor mans waste gate. {??}
NOTE: One {close} side of the valve will be drilled to lessen the surface area on that side.
Pressure/flow against the other {open} side of the valve will allow it to open.
{I think the differential pressure will do the work, because of the difference in surface area}
A weak spring will control the opening pressure / set point.
I hope........
Ride safe, Ted <Mad Scientist Grin>
