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.

How fast does turbo spin at idle?

After you shut the engine off, it takes 10 to 15 seconds to start again. It depends on the size of the engine and the hole it's trying to fill, but 2psi of boost is about 25,000- 30,000rpm.

Does a turbo spin all the time?

It will always spin while exhaust gas is flowing (which it always will be if the engine is running). However, it wont be spinning very quickly at low throttle openings (regardless of engine RPM) so the pressure in the in-take manifold wont be very high.

Do turbos boost at idle?

Boost pressure is usually very low at idle no load condition. Turbo is turning at lower speed due to smaller volume of exhaust going thru turbo. Your highest boost will happen at full load on engine and has the most volume going thru the turbo .

At what engine revs does turbo kick in?

Turbo starts to give the engine more power supposedly around 1760/1900 rpm. Turbo starts to give the engine more power supposedly around 1760/1900 rpm.

Does my rear turbo spin at idle

How long does it take a turbo to kick in?

WHERE DOES TURBO LAG COME IN? Turbo lag is what you feel when you're waiting for the boost to kick in. Because the turbines do take time to spool (or spin), there is some degree of turbo lag. After depressing the accelerator pedal, it takes about a second (in most modern cars) for the turbo to spool.

Can you adjust when turbo kicks in?

A turbo can't be adjusted in the way you want.

Does a turbo spool in park?

The short answer is that the engine must be under load for the turbo to spool/build boost. It will not build much if any boost in neutral or park.

How long should you idle a turbo car?

In turn, doing this for a sustained period means one will end up damaging the turbocharger, with the heat getting onto other components. To prevent this, most manufacturers recommend that at start-up, you idle the car for at least two minutes.

Why should you let a turbo idle?

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.

How do you know if your turbo kicks in?

Press gas pedal, exhaust is generated, turbo starts to spin, more air and fuel is pushed into the engine, power increases. This starts to happen right off idle and you can feel it when starting from a stop. Press the pedal and a second or two later you feel the turbo kick in.

Should you let a turbo car warm up?

Warming up a turbocharged car would heat up the engine oil as well as other powertrain components. It was also recommended that if you just drove your turbocharged car to let it run for a minute before you shut it off.

Do turbo engines need to idle before turning off?

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 free should a turbo spin?

Even journal bearing turbos should have very low friction. If you ever seen a turbo running after an engine has shut down then they can continue spinning for a good 5-6 seconds (ball bearing turbo can spin for ages).

How long does it take for a turbo to stop spinning?

35 seconds to stop spinning from idle.

Do you have to let 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.

Why is cold air good for turbos?

Replace your intercooler with a more efficient model – reducing charged air temperatures and improving overall performance. Fit a cold air intake to your engine – meaning that colder, denser air is brought into the turbocharger. Fit a larger air intake – increasing the amount of air available to your turbo.

Do turbos shorten engine life?

Turbochargers, Supercharges, and Nitrous all create higher cylinder pressures. This DOES reduce engine life ... PERIOD. Turbos and Superchargers make more heat, and heat reduces an engine's life ...

Does a turbo work in neutral?

In neutral, there's no load on the engine, so the injectors are only opened to say 10% when you floor it, whereas when you're in gear and you floor it, the injectors are opened 100%. The small amount of gas being ignited at idle isn't enough to create enough exhaust gasses to spool the turbo's.

Will a car build boost in neutral?

boost is directly in conjuction with load....you cant really build much load in neutral so there for you cant really build much boost.

Does a turbo always make boost?

The turbocharger doesn't boost the engine all the time. If you're driving moderately, the air drawn in at atmospheric pressure is enough, and the engine operates like it's naturally-aspirated. When you hit the throttle, the engine works harder and creates more exhaust pressure.

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.

Why does my turbo kick in late?

The lag comes from the time it takes the engine to create enough exhaust pressure to spin the turbo and pump compressed intake air into the engine and is longest when the engine is in a low-rpm, low-load cruising situation.

Do all turbo cars have turbo lag?

However, today things are much different. The advanced materials and designs of the turbochargers fitted to most modern engines mean that the lag is fairly minimal, to the point that the vast majority of drivers won't even notice it.

Why does a turbo only boost under load?

The only reason there is lower boost is due to the lack of enough air mass to put the turbo into efficiency range and cause it to pressurize the intake.
