dump valve

The longevity issue is not as big as deal in respect to longevity if you are only dumping the excess boost pressure without fuel enrichment and ignition retard. The main issue is if there is over-excessive fuel then there are some serious shock waves as in the full ant-lag. The full motorsports anti-lag retards ignition to past TDC, dumps enrichment fuel and dumps alot of air around the throttle plate making large explosions that would require hearty exhaust valves and ceramic turbine parts. The dump valve only method actually helps pump cooler air through the turbo when the motor coasts with the throttle closed.
