Water injection is an interesting subject, but its really not incredibly useful in and of itself for increasing fuel economy. It can be used along with engine modifications to increase compression ratio since it supresses detonation and allows you to maintain stoimetric air/fuel ratios. However, you better build a reliable system because if it breaks, your engine can/will be damaged.
