I need someone to share some knowledge on water injection for a sbc w/blower setup. The manu's claim big HP gains and almost zero risk of detonation. Supposedly I could run up to 12lbs boost on a 9:1 engine w/pump gas. If this is the case and a system cost under $300.00, the hp to cost ratio gets very good and seems like they would be very popular. Perfect setup for the street beings you could (supposedly) run 12:1 on pump gas and stay out of detonation. Anybody got personal experience? Let's hear it!!
