The waste gate controls the boost coming out of a turbo by bleeding off exhaust gases/pressure to the turbo's turbine. By control the amount of gases/pressure the turbine see's, it controls the turbo's speed/pressure.
a turbo charger unlike a super charger sucks in air releasing pressure ie in the form of a waste gate. unlike a super charger a turbo does not use horse power to generate horse power. differences from gas to diesel doesnt change
Please clarify your question and include make, model, year, engine size and transmission. Are you asking about an actuator for the turbo charger? The waste gate on the turbo charger? Or for the heater vent controls?
Faulty waste gate, improperly sized turbine housing.
yes some turbos come with out a waste gate (none waste gated turbo)
Depends on where the problem is. If the problem is the wastegate acutuator (gold or rusty cylinder attached to the turbo), replace it. If the problem is the wastegate flapper assembly (arm attached to turbine housing on the turbo), pentrating oil works wonders. If that does not work, you have to replace the turbine housing.
By using a charger waste is reduced since the batteries are rechargeable and do not have to be thrown away.
turbo charger and super charger are close to the same thing just ones belt driven and other is powered by the exhaust the turbo is always spinning even at idle but most turbo on car will kick in about 1k rpm depending on how hard you push the gas pedal down will determine how fast the turbo will produce more boost (turbo's are always spinning its just the waste gate that close when the engine loses vacuum(hitting the gas harder)once it lose vacuum the valve closes keeping all the boost in the intake) i know on my supra i produce boost at 900 rpm's and will be at max 15psi boost at around 2k rpm's
to waste time
It would be a waste of time and money. You would have to make a special adapter to hook the exhaust to the manifold. On a turbo header, the exhaust hooks to the turbo and the turbo to the manifold.
It's right there mounted to the turbo itself....
this sounds alot like a turbo failure, although there could well be a leak in the pipes leading from the turbo to the intercooler, or from the intercooler to the inlet manifold. also check the intercooler for leaks. or it is the vacuum pipe that operates the waste gate on the turbo, or a seized waste gate.
Either the turbo/turbine housing is too large, the waste gate is stuck open, or the turbine fins are damaged.
