This 12VDC valve boasts 3500 PSI operating pressure, 11 GPM flow (@50 PSI pressure drop), -8 female ports and draws less than 1.7A. It is simply the best we've ever seen for this kind of duty. Perfect as a high-speed lean out, stage valve, or "converter helper", this fantastic valve can do it all.
The lightweight aluminum valve body is hard anodized for long life. Assembly includes a brass pill plug, button head plugs in one of the IN and OUT ports, and -6 male fittings for attaching your hoses. This body accepts standard Enderle screw-in bypass pills which are not included but RBS can supply at an additional cost if the racer chooses. The coil can be rotated to position the non-polarity sensitive leads in any direction desired. The thru holes in the valve body allow bolting the valve to the vehicle with 1/4" socket head cap screws (not supplied).
What's a "Converter helper"? When a fuel injected motor is on a rev limiter, the motor cools down severely since a large quantity of fuel is not being burned.
This valve can be wired to the transbrake circuit so that when the transbrake is set, the valve opens and keeps the motor hot, lean and mean while on the rev limiter. When the transbrake is released, the valve closes and the system goes back to full rich for the launch. Amazing improvements in 60' times can result on supercharged or naturally aspirated applications. Typically, removing 2 to 3% of the normal fuel required by the motor is a good place to start, removing up to 5% in some cases.
Solenoid valves are also used on clutch cars triggered by a clutch switch and are referred to as a "stage valve". When revving the motor prior to launch (while the car is staged), the valve keeps the motor from loading-up while under no load and at partial throttle where the air fuel ratio is difficult to tune. This valve comes with gas and methanol compatible seals. Racer must specify nitromethane if that is the fuel of choice to be used with the valve.
This valve is supplied with plain 16" wire leads for connection to your vehicle. RBS offers a couple of standard connection options at additional cost which the racer can check out under part number #395-0013 Molex or #395-0014 Deutsch.
