Only ever used with straight water and hardly used. Was on my daily stagea and barely used for a year. No tank included. 3 or 4 jets, have to check what sizes. These setups reference a map, maf or injector duty cycle to inject , meaning it can be setup and tuned to be very progressive. Can also be setup to be an off or on style setup. The valve allows much greater control of injecting, rather than other styles that vary pump speed. Varying pump speed gives a very narrow use able range of spray. Google or ask me for more info, happy to explain why I bought this. Only selling to return car to stock. No turbo action for me for a while, so I'll move this on. http://www.howertonengineering.net/aquamist-hfs-2-injection-system/ Pics available once I remove it this weekend. $475 Fairview Park SA Ben
