So as many people do, we do our best thinking while driving.
While analyzing my ridiculously unacceptable pulsing throttle response, I wondered if there is such a phenomenon of pump cavitation on the turbo. Physically and logically I would say "ABSOLUTELY YES!"
I am running a Cobb stage 2 which REQUIRES a stock airbox and stock style air filter, which may be restrictive enough to create an excessive vacuum and cause the turbo to cavitate.
I could definitely understand the cyclical pulsing of high vacuum back and forth as the turbo loses its "prime".
This pulsing throttle response always occurs at moderate and steady acceleration "under boost".
Under aggressive acceleration pulsing does not occur, and I could see the turbo losing "prime" continuously which would make sense why it wouldn't cycle/pulse under extreme acceleration. I could imagine that I am still obtaining boost due to the wastegate compensating. Logically this all makes sense.
I'd love to hear logical, physics based, intelligent opinions, and real world experience on the topic. Ideas?
