Even Porsche seemed to see it's 930 IC was less than ideal.

The special 930SC had a larger intercooler that was the same size as the one the OEM maker built for RUF.

Then with the 91 turbo a much larger intercooler was fitted that had a more efficient BOV to.

Then there was the factory race Group B 930's that used a full bay intercooler built by Kremer for Porsche.

The stock IC might work ok for a sub 300hp street car but probably not much else. It might keep the velocity up but it is going to be more restrictive and create a pressure drop that will put the turbo at a higher pressure and lower efficiency than it could be and it is just dose not make for a great temp drop.

Usually changing the IC is good for 20 hp or so with no other changes.

It really is not worth doing much more than cleaning it unless you just like the look I suspect.
