Why would I want/need a water cooled wastegate?

In road racing we can heat soak the wastegates and potentially melt the bladders if we don't have enough airflow over the wastegate. Water cooling would keep the bladder cool and also prevent the spring weakening with heat soak, opening earlier and dropping our boost levels. I've yet to damage a bladder, but I have had boost fall off over a race as everything gets really hot. Whether this is just related to increasing intake temperatures or was the wastegate, is hard to say.

^ Nicely put Trent.

This is the reason I posted this in the race car tech section of the forum, its not something that is needed for a street car.

A street driven rotary that is pushed hard usually changes the top hat color of the wastegate( if making decent power). In these cases probably a good idea to hook up the ports properly..
