Does water injection work for normally aspirated cars?
Water injection can benefit NA engines, but not to the extent that it can forced induction engines. You may be able to run more timing advance on an NA engine with water injection and hence get more power. You will also benefit from the cleaning properties of water injection as it will remove carbon buildup on the pistons. In this kits current form it will not work correctly with a normally aspirated engine. This is due to the pressure switches. A future ‘stage 3’ kit it being considered which will use electronics to switch on/off the solenoid valves. This controller could be tied to either boost pressure, or throttle position for NA applications.
