Looking for a simple and affordable way to create and manage multiple stages of water methanol injection here it is. Our two stage mechanical switch controller assembly allows users the ability to individually control when each solenoid opens through the use of separate adjustable boost pressure switches.

Since the introduction and use of water methanol injection systems in the automotive industry. The oldest and most tried and proven way of controlling water methanol injection systems on forced induction applications has been through the use of adjustable boost pressure switches. Universal by design. Our three stage system can be fitted to any type of forced induction application (turbo, centrifugal, positive displacement both gas and diesel applications) and is perfectly suited for both street and race enthusiasts.

Features Include:

• Adjustable pressure switches
• Billet manifold assembly
• Normally open contacts
• Made from billet brass
• 1/8-27 NPT male port 
• .250" spade terminals 
• Small compact design
• Polarity can be reversed
• Voltage input 12-16 VDC
• Piston diaphragm design 
• 1/8" allen screw adjustment
• Can withstand up to 1200 psi
• Repeatability +/- 3% of set point
• Temperature range -20 F to 205 F
• Dimensions 2.20" long by 1.0" wide
• Dependable long life (1 million cycles)

Special Notes:

• Polarity does not matter, switch can be wired both ways
• Switch must be used with a relay
