Can you have a wastegate without a turbo?
Thanks! You won’t be able to control boost, and you’ll over-spin the turbo. Basically, without a wastegate that turbo will become a nice Christmas mantle piece decoration.
Can you move a turbo actuator by hand?
They do move, but are very hard to do by hand, usually if you have a pair of pliers then you can shift them, BUT, they should move, so if yours is siezed then you’ll be down on power… try moving it back and forth and applying some WD40 to free it up a bit.
What happens with no wastegate?
With no wastegate the turbine is even more of a restriction at higher rpms and boost levels so 30psi with a welded wastegate could be no better than 25psi in a normal setup.
How does the wastegate actuator work on a turbo?
Then this rod is connected to another rod which goes to the turbo’s wastegate. The spring inside the actuator, in it’s resting state, is pushing the diaphragm as far as it can go, which in turn is pushing the connecting rod as far as it can go, which in turn is pushing the wastegate itself on the turbo closed.
Why is my wastegate actuator softening over time?
The return spring on the actuator arm can soften over time so you never develop full boost (the wastegate is always bleeding air from the turbo), there should be an amount of pre-load on the actuator spring.
Where does the vacuum go in a turbo diesel?
Quick question on TURBO DIESEL wastegates: I know the wastegate opens and closes to control boost. I know that the vacuum line goes to the control solenoid which opens or closes to put vacuum (or not) on the actuator which then opens and closes the wastegate.
How does the wastegate work on a car?
It’s a valve that is controlled by an electronic solenoid that allows engine vacuum into the unit to make it open up, and in turn open the turbo’s wastegate to bleed off excessive boost, and hence not allow massive boost pressure to build up and destroy the engine.
