The JETWORKS FLOW CONTROL VALVE
provides improved throttle response and much quicker starts by drying out your water box
at low rpm and idle sppeds. Tests have shown an average acceleration improvement of 12
feet over a non-equipped model in the first 50 feet. Allows unrestricted water flow to the
stinger for better top speed. Yet it controls the amount of water at low speeds for better
response. It also allows for an easier tuning of the carburetors. It does not interfere
with normal engine or exhaust pipe cooling and is compatible with all electronic water
In a race start situation, the
craft is under a slight load while waiting the start, water fills up the water box and
exhaust hoses. Upon sudden acceleration all of this water must be forced out quickly
before full exhaust flow can occur. During this time the craft feels a slight hesitation
and/or sluggishness, especially when the water box is mounted up front and has a rear
exhaust. Improves response through turns when the throttle is let off for a split second.
This drys out the water box while at the same time raising the water pressure slightly in
the head pipe of the exhaust. This raised water pressure allows the water injection
orifices and/or nozzles to work quicker and more effectively.
Two models are available:
The standard flow control valve is preset at 3.5p.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. Pressure can be tested with a
pop off gauge. Both models feature a positive sealing viton on metal seals with a
precision calibrated, variable rate spring. This allows for true water flow and pressure
management of multiple water lines and dedicated cooling line applications.
