Turbo cannot be turned off when in use because it is a forced induction that makes use of exhaust gases to work. You cannot manually switch off a turbo, but a wastegate valve device regulates it.
The turbocharger cannot be switched when you like using any manual method. Instead, the turbo is responsive to the throttle. So how much boost the turbo gives depends on how hard the driver hits the throttle. Knowing that the throttle cannot switch off the turbo system is essential.
The turbo system is only regulated using the wastegate valve. It works by controlling the amount of exhaust gas that goes into the turbines. Once the exhaust going into the turbines becomes excess, and the pressure in the turbo system becomes too much, the wastegate valve will open up and divert these gases away from the turbines.
However, this does not automatically stop the turbine from working. It could reduce the level at which it is working.
Personally, I have not disconnected my turbo with my Honda Civic, but i have had a failed turbo system and once tried to bypass it. I would say it did not give me the best result at that time. I experienced a bad fuel economy and my engine boost was very poor.
Can You Disconnect Turbo?
You cannot disconnect a turbo. It is a great misconception to think that you can. You cannot disconnect the turbo system because the system is an integral part of the exhaust and induction system.
The turbo system is not just any part of your vehicle that you can do without disconnecting or uninstalling. It is attached to the car’s exhaust system because exhaust gases power it. Disconnecting the turbo will mean disconnecting an integral part of the exhaust system.
If you do manage to remove or install the turbo system, you might hate your vehicle. You can expect to have a much lower horsepower generated by the engine, more fuel consumption, and many more problems that will make your vehicle a living hell to drive.
If your turbo is failing or has failed, it is not advisable to go for a disconnection. Better still, repair the turbo system. Also, if you have a failed turbo system and do not manage it, you are just a step ahead of engine failure. The failed engine parts can drop into the system quickly and damage many parts of your engine.
How Do You Bypass a Turbocharger?
It is possible to bypass a turbocharger by changing your intake manifold and intake pipe, but it takes a lot of work, and you may require mechanical knowledge.
To bypass a turbocharger, you must get an intake pipe that can go past the turbocharger and connect them to the intake manifold directly. Typically, the intake pipe is meant to be connected to the turbocharger. To bypass the turbo, you need to use a longer intake pipe.
Also, you will need to replace it with a manifold one that can accommodate the changes you will be making. Not all vehicles will need a change in the manifold. Then you will need to remove any form of coolant lines that are going into the turbo.
You will need a new downpipe connecting the manifold and running down to the catalytic converter. After these new parts have been connected, you will need to also get a new computer for a vehicle that will not search for your turbo.
After doing all these, you may have successfully bypassed the turbo system.
Can a Turbo Engine Run Without the Turbo?
It is possible to run your turbo engine without a turbo, but this is extremely difficult to do and will be expensive. You will have to rework your engine to be able to achieve this.
It is possible to run your engine without a turbo, but it could be hazardous to the engine’s health. If the issue with the turbo is related to oil or internal components, then engine failure is imminent.
Running a turbocharged engine without the turbo is like having a broken vehicle. It will perform poorly. The engine boost will be poor, as well as the fuel economy. You will also experience a lot of problems before eventual engine failure.
To achieve a turbo engine working without a turbo system, you will have to rework the engine and the exhaust system if the turbo is removed. The turbo system is attached to the exhaust system and removing the turbo means creating a vast and vital space that needs to be filled up.
When the turbo is removed, you will need to replace many parts in the vehicle, and this part needs to be custom-made to fill in the space created by the turbo. You will need custom-made exhaust parts and an intake system. Making or creating these parts will cost a lot.
You will also have to have a custom engine tuning because it relies heavily on the turbocharger, and removing it will drastically reduce the engine’s efficiency. It does not stop there; you will probably need a different fuel injector and have to plug the coolant and oil lines initially connected to the turbo.
Doing this will cost you an insane amount of money. It would be best if you just repaired the turbo system.
Q: Are Turbos Hard on Engines?
Turbos are not hard on the engine and are entirely safe to use. They will not cause any damage to the engine system as long as they are working perfectly. The problem your engine may have with a turbo system is when the turbo begins to fail, and your engine is heading for a big problem.
Q: How Long Do Turbo Engines Last?
Turbo is made to last for a long time, at least as long as the vehicle will last. However, many factors could cause turbo engines to have problems. Some of the problems may include how they are built, the way they are used, and the maintenance culture of the person using the engine. All these determine how long the turbo engine will last.
Q: Do Turbos Use More Gas?
Turbo engines are built to be fuel efficient and are an excellent way to reduce gas costs. The turbo helps increase the air going into the combustion chamber, which creates more combustion, and less fuel creates the same combustion.
Q: Do Turbos Shorten Engine Life?
Turbos are entirely healthy to use as long as they are in good working conditions. It is a healthy way to give your engine a better boost. The health of your engine depends on many other factors, which include maintenance of the engine.
