In a petrol car the turbo will most likely spool out of control until either it or your engine malfunctions, usually the engine's head gasket ('s). In a diesel engine it could go either way. Some are vacuum controlled and some are electronically controlled. If electronically controlled it will not produce boost. If vacuum controlled, normally the turbo will only produce a few extra lbs of boost, if any.
I guess you could, but what would it do. A wastegate controls the amount of boost and with no turbo there is no boost to control.
You shouldn't. The wastegate eliminates the extra boost when it's not needed.
There already is a wastegate in turbo diesel engines, most all turbo (petrol/diesel) engines for that matter. The purpose of a wastegate is to give the exhaust gasses a passage to flow that doesn't spool the turbo over the desired psi. The 2 most common wastegate designs are: 1. a series veins that surround the exhaust wheel of the turbo and pivot to open and close off the pathway to the exhaust wheel. 2. a swinging plug that opens a hole at peak boost and allows exhaust gasses to pass whithout spinning the turbo any further.
Integral part of turbo.
Depends on how the ECU controls the turbo. If the ECU never lets the wastegate open, the turbo may overspin, which will damage it. On Audi/VW cars, a bad tune can cause an overlean condition, which melts the wastegate flapper door. This will cause your turbo to not boost.
modifying or installing an adjustable wastegate.
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.
Only true way is to pop the hood and see if it has a turbo on it or not. To tell by sound just listen for a "psshhhh" sound after the gas is let off, that's the wastegate dumping the extra pressure built up by the turbo. There is another sound it makes but kind of hard to describe that in text. But the wastegate dumping of pressure is a sure bet its a turbo. Or if the owner has the badge work shaved so you can tell what it is...it also could be a VR6 with a supercharger / Turbo set up. Only real way is to pop the hood and look for the turbo on the back of the engine on the exhaust manifold or look for a boost gauge on the dash cluster.
A turbo wastegate solenoid is an electromechanical component used in turbocharged engines to control the opening and closing of the wastegate, which regulates exhaust flow to the turbocharger. By managing boost pressure, the solenoid helps maintain optimal engine performance and efficiency. When the boost pressure reaches a predetermined level, the solenoid signals the wastegate to open, diverting exhaust gases away from the turbocharger to prevent overboost and potential engine damage.
Yes, you can replace a wastegate turbo with a non-wastegate turbo, but it requires careful consideration. Non-wastegate turbos rely on external methods to manage boost pressure, so you'll need to implement a separate boost control system to prevent overboosting. Additionally, compatibility with your engine and exhaust system must be ensured for optimal performance. Overall, it's a more complex setup that may not be suitable for all applications.
if the turbo is the factory equipped turbo and not an aftermarket/performance turbo, your wastegate solenoid may be malfunctioning or you may have a vacuum leak somewhere. Your turbo's wastegate actuator is run off vacuum, and it controls boost. If the actuator never actuates, the turbo will make way too much boost.If it is a performance/upgrade turbo, surge is caused by poor turbocharger design. You have to send the turbo to a turbo shop to fix the surge issuehelp@coloradoturbo.com
It screws into the turbocharger. Look for wires running to the turbo.
