While your car’s engine revs, at cruise, at around 2,000 rpm, a turbo’s turbine can reach rotational speeds of more than 280,000 rpm. … Toasty Turbines: Turbos operate in extreme heat, in excess of 1050 °C in gasoline engines. Even in diesel engines they run hotter than the temperature of molten lava.
Why do turbo cars run hotter?
Turbocharged cars tend to have higher pressures and temperatures within the combustion chamber, which is why they have reduced compression ratios to compensate. If your car is modified, you can keep it reliable by running a rich mixture and using high quality, high octane fuels.
What temperature does a turbo run at?
The turbines in most current production turbochargers are suitable for continuous operation at an exhaust gas inlet temperature of 1750°F (950°C).
Do turbo engines run better in cold weather?
As air temperature increases, the density of the air, and the amount of oxygen it holds decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.
How long should you let a turbo cool down?
When you drive it gently around town, 15 seconds should be more than adequate. When you drive the car hard ie. when your husband drives it, you should let it cool for 30 to 60 seconds.
Is it bad to idle a turbo car?
Drive your car gently for the last minute or two of the drive, or let the car idle afterwards for at least 60 seconds. By letting it run. the oil will continue to circulate and cool down the turbo. … Boost leaks can cause your turbo to overspin, which leads to failure.
Do turbos spin at idle?
Turbos spin whenever the engine is running, although not fast enough at Idle to produce enough air flow to be called as “boost”.
Are turbos bad in cold weather?
The biggest concerns are speed and heat and the solution is oil. … With any moving parts, the right oil is required to ensure lubrication – when cold, that oil is “thin” enough to provide that protection. In a turbo engine it also has to remain “thick” enough at extreme high temperatures to provide the same protection.
How do you ruin a turbo?
In terms of the turbocharger, it needs a constant flow of clean, quality oil. A lack of oil (oil starvation), incorrect grade of oil or poor quality oil will lead to a build up of contaminants in the engine (oil contamination). This can cause abrasive damage to the inside of the turbo.
