Mark, is the difference in the MFI pump timing between the rsr pumps and the standard street pumps solely related to the space cams or is it a combination of things? In other words if someone puts an rsr space cam in an early 911s MFI injection pump like 1970, would that change the MFI pump timing from s to rsr or it more related to the cam in the engine.
It seems that it could get complicated if one modifies an S space cam or has a custom one made to match a GE-60. In that case is there a way to calculate the MFI timing or would you try standard S setting first?
