Yes exactly! Not so much about the weight but too big intercooler actually creates more turbo lag too! The reason why you often see people go to upgrade intercooler first is because that's the one they feel the improvement in power coz it makes the air intake cooler hence can make more power. On the other hand radiator sometimes is 2nd priority because they are to maintain reliability but not make extra power if the engine is still within normal temp.Depends I guess. If the cooling from earlier intercooler is insufficient, then upgrading to a larger one might be beneficial. But if cooling is already good enough, not much point to increase the size of intercooler... And you add in more weight to the front of the car.
Edit: btw tire tread becomes talking about cooling! Should talk in the other radiator tread huh?
