25MM Dual Piston BOV Blow off Turbo for Audi A4 S4,for Golf,for Jetta 25 PSI

Turbo relief valve:

The turbocharger doesn't stop working!As a result of inertia, the turbocharger continues to rotate at a speed of more than 100, 000 RPM.
Basic introduction of turbo relief valve:

When driving a turbocharged vehicle, when the accelerator pedal accelerates, the throttle opens and the engine increases with the increase of speed."Voice, high temperature and high pressure exhaust gas from engine energy promote the exhaust turbine rotating, when reaching the turbocharger speed at work (that is, make the turbine rotation for more than 100000 revolutions per minute), the turbocharger to the surrounding air is compressed, the engine air inflow increase and improve the dynamic performance of engine.
But when we are receiving, decrease the throttle opening until in the closed state of idle speed, that is to say, do not need engine air intake, or if air flow in the inlet pipe will be stuck at the choke.Now as you can imagine, this still continue to be continuously compressed air into the intake pipe, if this part of the high pressure air in the intake pipe can't be discharged in time, will make the intake pipe pressure rise rapidly, acceleration drag hysteresis, not free in light and heavy damage or may cause throttle intake pipe burst.

At this point, a discharge device is required to be added to the inlet pipe to remove excess pressure from the compressed air in the pipe.In fact, the relief valve is installed on the inlet pipe to control the pressure pressure.The opening of the relief valve is controlled by the electromagnetic coil operated by ECU (electronic control unit).The ECU will be judged according to the pressure of the turbocharged outlet, and once the pressure exceeds the critical value, the electromagnetic coil can be energized or out of control, thus opening or closing the relief valve.
