Lack of power after turbo replaced


Can a turbo cause loss of power?

The concept sounds simple but turbochargers are complicated bits of kit. They have pipework that can get blocked or leak. This results in a loss of pressure and therefore power.

Does a new turbo need running in?

Installing a new turbo. Before removing the turbo, we advise you let the engine idle to operating temperature before switching off and draining the engine oil from the sump (be VERY careful as oil will be HOT). As the oil is more fluid when warm, you have a greater chance of removing as much as possible.

What to do after replacing a turbo?

After installing a new turbo, make sure to prime the unit by injecting clean engine oil into the oil feed hole and turning the rotor assembly by hand.

How long do you need to run in a new turbo?

If you don’t have an oil temperature gauge, a good time is usually a few minutes after your car has reached normal operating temperatures. This usually takes 5-10 minutes but depends on oil type and environmental conditions.

Why is my turbo not boosting?

As you know, the main cause of turbo failure is poor oil quality or no oil. But low engine oil level can be caused by the turbo too. It is common for turbo seals to leak and allow the compressor to suck up the engine oil and send it into the engine.

Can a turbo engine run without the turbo?

If you don’t have a turbo, your engine will start and run without one, but make sure the oil line is not connected to the engine.

How do you run a brand new turbo?

Nothing in a turbo needs running/breaking in, just the engine its bolted to, so if you fit a new turbo to an ‘old’ engine, go for it straight away if you want! Yep, just pull the fuel pump relay and crank for 5-10 seconds to get the oil line primed. Other than that, have at it…

How do I prepare my new turbo?

Oil next ensure the pedestal is clean and free of debris. Then reinstall the oil drain pipe then install the turbo on the pedestal and reassemble in reverse.

At what RPM do turbos kick in?

The turbo usually kicks on mine at 3K or just after. It depends on what gear and speed.

Does a new turbo need a break in period?

no break in period for a turbo.. They test the turbo by spinning it to over 100,000rpms before they send it out to you.

Can you daily drive a turbo car?

Yes, it is totally fine to daily drive a turbo car. In fact, turbocharging – at least from the perspective of many manufacturers – is more about making daily driving easier for the driver by making cars more powerful, more fuel efficient and easier to drive.

Do Turbos need to warm up?

Just as you need to warm up your engine, you need to let it cool down. Extended journeys and high speed driving creates a lot of heat in your turbocharger, and if you turn off the engine whilst it’s still hot, you can cook the oil inside, leading to unnecessary build up of carbonised oil inside your turbo.

How do I know if my turbo is working?

If you notice that your car isn’t accelerating as powerfully as it used to, or is slow to react to your input, this might be a sign that your turbo is failing. Similarly, a turbocharged car that struggles to maintain high speeds or isn’t able to reach speeds it once could may be experiencing turbo failure.

Is cold air better for turbo?

To improve overall performance, take advantage of the new midrange model that allows for the best air temperature reduction. Your turbocharger should have a cold air intake – that is, the engine should be cold before it can use gas. Make sure the turbo is offered more air by fitting a greater intake.

Do turbos spin at idle?

The turbo are always spinning when the engine is running, and will even spin down for for up to a couple of minutes after you shut the engine off.

Do you need to let your turbo cool down?

Turbocharged engines do need to cool down before they are turned off. But in nearly all driving conditions, the engine does not reach temperatures that require a deliberate cooling down period.

How long should you let your turbo cool down?

Idling the engine cools the turbo because it circulates the oil, yet does not make the turbo “work.” The amount of cooling it needs is directly related to the way you just finished driving it. When you drive it gently around town, 15 seconds should be more than adequate.
