I'd definately consider water injection for the emergency overboost
situation, but I don't think I would use it as a knock control device.
The intercooler will most likely be in the left side intake duct
thing. (might use a water mist a-la sti intercooler mister to lower
temps even more)

btw... have you been to the bar in sf called zeitgeist?, just curious.
