Regarding your problem, obviously the coolant flow through the intercooler is not doing the job so something is wrong there. Your old CM30 pump may have been faulty and then when you replaced it with the new CM30 pump maybe (as Jim suggested) you wired it backward and the pump is running backward. That would fit your symptoms . . .

When you get it sorted out, I would suggest installing the separate intercooler resevoir tank (as referenced in the links below). You'' be able to see the coolant pumping through that clear hose and removing the reservoir cap see it spitting into the reservoir tank. You'll KNOW that your intercooler pump is working properly.
