To better understand the benefits of external wastegates, a simplified understanding of the operation of a wastegate is needed. To build boost pressure, the wastegate diaphram/valve
remains closed in order to direct all exhaust energy to the turbine. To maintain a given boost pressure, the wastegate (positioned upstream from the turbo) reroutes excess exhaust energy around the turbine wheel by opening its diaphram/valve. As greater exhaust output is created
from higher levels of engine performance, the stock internal wastegate actuators begin to lose
their effectiveness because the amount of exhaust flow to be bypassed is now beyond their intended operating range. As the result of exhaust flow being greater than the valves'
capacity to discharge, more exhaust flow is directed to the turbine and additional boost is
created, which is commonly referred to as boost creep. Boost spikes may also occur due to the larger volume of exhaust energy now being created.
