Wastegate On Intake

MoulaZ · 07-20-2018, 03:44 AM

Sounds like a nifty idea. Curious if it'll work though.

Have you considered the wastegates don't really bleed much in the grand scheme of things? The majority of exhaust gas coming out of the engine is flowing through the Turbo and that little bit of excess flow is being diverted to keep the Turbo from hitting half a billion RPM and self destructing. Even between gears or on decel, when TBs shut and engine exhaust flow drops dramatically, that's even less air the wastegates are dealing with.

Where as in an SC application on the intake side, you'd be exposing that crazy amount of flow directly to the wastegate and expecting it to stably bleed off that unwanted extra 4 PSI, even when letting off the throttle and RPM is still near redline, SC is still making stupid amounts of boost.

Maybe I'm just talking sh*t. I still love the idea, but that's the first thought that came to my mind. Sub'd.
