i bould a waterinjection for my diy engine. Compression 12,5:1 and afr about 16,2 at full throttle. I need the Water/Ethanol to cool down Pistons and Valves and to prevent knocking. It works. Without the WAES i only could drive with AFR 14 at full trottle AND take back the injection values -> roundabout 20% lesser efficency.
