Put simply — a wastegate prevents the boost pressure from climbing indefinitely and consequently blowing the engine.

When the boost pressure exceeds the spring value, the actuator will progressively open the wastegate, bypassing some of the exhaust gases therefore maintaining the boost pressure at the set level. Upon shutting the throttle, vacuum is created in the inlet manifold, this vacuum combined with the pressure in the intercooler pipe forces the piston to open, releasing excess boost pressure in the intake system.

Under boost with the throttle open, the blow-off valve remains shut. A typical BOV consists of an inlet and outlet port, a piston, a spring and a vacuum connection point.

With a BOV, the excess boost pressure is released, keeping the turbine spinning and thus reducing the turbo lag effect.

Without a BOV, upon shutting the throttle, the pressurised air caught between the free-spinning turbo and the shut throttle is forced back through the turbine blades, this, in turn, forces the turbine to slow down or stall.

In its resting position, a wastegate is shut, and as the boost pressure builds, force is applied to the actuator or diaphram. A BOV is usually mounted on the intercooler pipework between the turbocharger compressor and the throttle body, ideally on the throttle body side of the intercooler.

Why an External wastegate may be needed Most tuners will recommend an external wastegate for any engine producing hp or more, as running high boost through a factory internal wastegate can overpower the actuator spring, limiting maximum boost level.

A wastegate consists of an inlet and outlet port, a valve and a pressure actuator.

How a wastegate works A pressure actuator or diaphram for an external gatecontrolled by boost pressure determines whether the wastegate is open or shut. Without a BOV, the compressor surge slows the turbine down, which then takes longer to spool up again when the throttle is opened.

In its resting position, a spring holds the piston shut against the intake port. Aftermarket external wastegates feature bigger inlet and outlet ports, higher pressure springs and bigger actuator diaphragms to effectively control high boost pressure.

A perfect example of this is during on boost gear changes.
