Re. Well, I have MK hardware and it is Rotrex (KKK turbine compressor side, NO OFFENCE TO MINORITIES, IT IS THE NAME OF THE COMPRESSOR). I also have two pullies - one for 7.5 psi boost and another for 9 psi boost.

Do you mean that you are using a MK Motorsports supercharger on your 540i? Back in 1998 when they first brought out the conversion, they used a vortech supercharger. They must have changed.

Re. : With 7.5 boost on Vortech POS with 70% adiabatic efficiency and no aftercooling you can hardly get over 410 hp on pump gas.

I have seen over 420hp with no aftercooling at 6 psi on a 4.4 litre vortech supercharged car.
