There is a water to water intercooler on the SRT-6 that has its own electric pump.
It does its job, but only keeps it running about the same temp as the engine coolant, since that is what it uses to push through the intercooler in front of the radiator before it gets to the supercharger.

I have been thinking about adding a water/alcohol injection system to it, to help reduce the air intake temps which would and add some hp due to the cooler temps and the alcohol. The system would be self activated upon boost, so it would only spray when it sees a certain amount of boost.

In the SRT-4 world, people use it all the time, and actually use windshield washer fluid to spray into the intake just before the throttle body.
On the SRT-6 though, I'd probably spray it after the throttle body and supercharger...I'd put it in the "Y" pipe/pressure pipe after the supercharger, because I'm not sure it would be a good idea to spray water/alcohol into the supercharger...
