Hey all,
just wanting some feedback to my proposed water injection setup.
the main reason for the water injection is that in summer here (ie. now) the outside temp regulary hits 40°C or more. I am only able to use 91 ron unleaded here, and at present any outside temps above 28°C i can only expect base boost (which is set at 3 psi - 2 psi lower than stock) because of apc doing its job at reducing boost because of knock. now the main problem is that i am getting knock at around 2 psi of boost... so APC cant even prevent the knock that is occuring.. hence H2O injection.
I intend on using a fuel pump of sorts (have to find a suitable one first), the 5th injector out of my old C900 GLE that is now basicaly dead, the washer resivoir, and a boost switch set to 2 psi.
the pump will run with the ignition on (having a spil valve that vents excess pressure to the resivoir), and i would use the boost switch to open the injector.
I am toying with the idea of using a FPR like the one that is used on the fuel line to regulate pressure according to boost, therefore with the higher air flow at higher boost, i can get higher water flow throgh the injector.
anyone got any suggestions on this setup?
