Turbochargers typically operate at speeds ranging from 80,000 to 200,000+ revolutions per minute (rpm). The actual speed at which a turbocharger spins will depend on a number of factors, including the engine size and design, the size of the turbocharger, and the amount of boost pressure being generated.
In general, turbochargers on smaller engines will tend to spin at lower speeds, while those on larger engines will spin faster. The turbine wheel in a turbocharger is driven by the exhaust gases produced by the engine, so the speed at which it spins will also depend on the flow rate of these gases.
The speed of a turbocharger can also be affected by the boost pressure it is generating. Higher boost pressure will generally cause the turbo to spin faster, as it requires more energy to compress the air being fed into the engine.
Overall, the speed at which a turbocharger spins can vary significantly depending on the specific circumstances in which it is being used.
