Think of them as an extra set of fuel injectors -- except it would be a mix of water and alcohol. Also, you will want injectors that atomize the mix as much as possible -- even fuel can cause wetting and pool inside the IM if the atomization is poor (and especially when running cold). But, this is my whole point: If you need WI at 0 boost (i.e., atmospheric pressure) and part throttle/low load, but NOT under high load, WOT or near-WOT, you should play with the existing tune first and not invest the money, time and effort in adding an entire secondary fueling/cooling system... Moreover, high humidity will actually quench det -- it's water, highly atomized, and it displaces air... high pressure, high oxygen, high heat (which also increases pressure) are the potential problems -- but if you are knocking at part throttle and not at WOT, its a weird tuning foible that can be addressed with your existing tuning software. I'm telling you, the problem is either the tune (and if so, likely a problem on throttle tip-in, due either to too much spark advance, less than ideal valve timing or overlap, or a lean condition, causing a miss) or you aren't knocking. Datalog, see what is happening, under what conditions and where and use that as your guide.
