The purpose of the flow control valve is to increase bottom end response by eliminating water flow to the exhaust system and waterbox at idle and low Rpm’s. It can be installed on most system’s using the existing water supply to the pipes and/or the waterbox. The valve can be adjusted to restrict the water flow to the stingers, etc. This will help acceleration off the line and out of the corners. Tunable water is also used to control the power delivery, and / or water temperatures in the entire system. The possibilities are endless, offering a large performance gain is possible for a small investment.

Two models are available. The Standard Jetworks valve is preset at 3.5 p.s.i. and is adjustable by adding the supplied stainless steel shims to increase the spring tension. The Pro-Series valve is externally adjustable by turning the outer housing by hand.
