I am interested in putting a switchable system in the car, whereby by switching a solenoid a valve will effectively 'turn off' the BOV. Why - as my HKS SSQV is hidden behind the bumper, if i am stopped by cops then i can switch off the BOV avoiding defect.
Some basics on BOVs:
BOV is triggered by a boost feed from the inlet manifold, when idling or accelerating, the pressure on both sides of the throttle are equal, therefore the BOV remains closed. When there is boost and the throttle is snapped shut, there is vacuum in the intake manifold vs. boost on the turbo side, therefore the BOV opens.
So, if I can install a vacuum hose that always sees turbo side pressure, and have the BOV feed to be switchable between the inlet manifold side and turbo side vacuum hose pressures, then when
1. it sees the intake manifold pressure it will operate
2. it sees the turbo side pressure it will remain closed at all times.
My questions are:
1. is this actually possible (switchable in cabin)
2. where would i take the turbo side vacuum hose from?
3. does anyone know if i can get a switchable valve ie. a t-piece that can be electronically switched so it is possible to switch between the inlet manifold side and the turbo side pressure hoses?
4. does anyone actually understand what i am talking about?!?!
Thanks, and I hope that is clear!!
