Don’t need near the duration on exh as before and wanted my EVC before TDC. Old cams EVC was 2 after TDC. With a turbo exh back pressure is much higher so that has to be taken into consideration. Also a positive displacement blower needs all the cam it can get to help make top end power. Turbo does not care nearly as much.
Old was 230/242 .615/.604 115+4

You want the cam to complement the power Adder. With a positive displacement blower spec the cam for top end to make up for the shortcomings of the compressor, with a centrifugal supercharger you can get more aggressive off the bottom end as the supercharger is way more efficient on top end. Generally speaking a turbo cam will be closer to a NA Cam.
