Dose not help on a C2T. That is one of the best IC's bar none. However, Andial did increase the core size on the 1992 S2 for Porsche.

On a 930 the intercooler is not very efficient. A more efficient IC cools the air better making for a more dense mix. This gets more air and fuel into the cylinder at the same boost level.

The only significant change between an 89 930 and a 91 C2T is the intercooler. This bumped HP from somthing like 285 to 315. Yes there were other small changes like fins on the cylinders, a mapped ignition, and a relocated oil cooler.
