That is not necessarily correct but application/configuration dependant. Side to side is more efficient than front to back. Front to back is easier to package on a 930 due to throttle and turbo position. It is also more costly to do the cross cut side to side than the perpendicular cut front to back.

There are many books on this subject and many proven designs. If you are not using A/C and have room for a full bay intercooler it will obviously have a greater cooling capacity than a half bay intercooler. Front to back side to side makes no matter if you can make up the difference with surface area and size. This is not a race car.
