I thought Tone has a smaller pulley? The Aquamist system looks cleaner but I don't think it has that control box. Maybe mount it in the center console storeage bin under the arm rest. It looks like it's just something you program once or twice and forget about. I was thinking about water/alcohol injection yesterday, and I think one could run such a system and not have to run high octane fuel. The engine compression is low enough and the boost is low enough so I don't think it would be a problem running regular. The water injection system would be insurance at WOT or near WOT.
