Using a quick tooth count of those spur gears in the photos the blower looks to be running at engine speed. That blower looks to to be a bigger brother of the Godfrey Mk 22 cabin blower I fitted to an A7 racer some years ago, that needed to be run at 1.3 x engine speed to achieve 8 lbs of gauge boost.
