Hi I was wondering has anyone experimented with any type of headwork on a jackson racing supercharged car? If so what kind of gains have you seen? I am leaning towards a DPR Stage 6 package

 

A mild polish and maybe some porting too would be beneficial with forced induction. However longer duration cams may very well be counterproductive. With longer duration cams, the valve overlap is greater. This is desirable on an NA motor, but not normally on FI. During the overlap period you would loose boost and therefore power.
