Wastegate do not open based on rpm. Wastegate works by vacuum/intake pressure activation. Spring setting (external wastegate determine which atm pressure to open the valve and prevent over boost. There are other ways of managing or forcefully activating the actuator by ebc or internal ecu air pump activation (some complex cars)


Wastegate is sitting at the exhaust port. It's function is to bypass the exhaust gas from flowing to the turbo and generating more boost. The part where you say it dumps air is called blow off valve. The difference in pressure for after throttle body and before throttle body will activate the valve to relieve pressure.

Damn I'm late for the party.

And for goodness sake. Turbo never activates. Electric clutched superchargers do. Turbo works on load and spool basis. Turbo spins all the time so it's always spooling. It's dimension, cfm, pressure, load, weight of the centrifugal impellers and exhaust volume plus velocity determines the rate of boost.

There is a load sensor at the transmission. It's nothing new.

tido la dares. so active at this hour. tomorrow no need to work ka?

Not my working hour but I baca everything till this hour
