PI center dumps are quieter and run at a lower RPM 8000-8200
PI end dumps make a couple more horsepower and yes they are loud. They run best at 8600 but if I remember right they were rated to run between 8400-8800 RPM.

The end dumps have a lot broader power range. They run fine from 8200-8800 rpm. The centre dumps have a narrow window....from 7900-8200max. After 8200 they fall of real badly whereas the centre dumps not so much on an overrev.
