Does anybody know a reason why the expelled water from a Procharger intercooler could not/should not be re-introduced to the engine...?

I currently have the outlet of the intercooler going overboard but thought it might be a good idea to route it somewhere into the water jacket at the rear of the engine...??

Or am I hitting the pipe too hard...???

Seems like you would not want to add any restriction on the outlet side of the cooler, this would restrict thru-flow and make it less effective.
