Whats different about centrifugal / impellor tyre blowers?
A centrifugal belt driven blower (sometimes called a “Hair Dryer”) is very similar to a turbocharger. Both require high engine speeds to spin an impellor up to extremely high speeds, frequently in excess of 100,000 RPM, before they generate useful manifold pressure to increase power. Compared to a Terra charger, turbochargers and impellor type blowers have poor low engine RPM efficiency. For practical purposes increased torque and power at low to medium engine RPM is more useful for a wider range of vehicle applications and service conditions.
