I have a pump like this; I used it for a naturally aspirated engine, which I installed a turbocharger on myself.
After installing the turbo, the engine became noticeably more powerful.
I noticed this after installing a 2007 Transit rear axle with a 1:3.31 reduction on my '90 Transit.
Without a turbo on this axle, the car doesn't want to move at all.
But with a pump and a turbo corrector, the engine produces high torque at relatively high RPMs—over 2000.
With a standard pump and a hydraulic corrector, after tightening the hydraulic corrector screw, the engine produces high torque at lower RPMs—around 1500—and pulls great from idle.
If you have an Otosan pump, install it and don't hesitate.
However, after replacing the pump, you'll need to adjust the pump to achieve maximum engine efficiency.
