How Fast Do Turbos Spin

The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) — that’s about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high.

How does a turbo spin so fast?

It uses the exhaust gas to drive a turbine. This spins an air compressor that pushes extra air (and oxygen) into the cylinders, allowing them to burn more fuel each second. That’s why a turbocharged car can produce more power (which is another way of saying “more energy per second”).

How fast do turbos 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.
