We've searched high and low and tried many different solenoid valves for fuel injection lean-out duties. This fantastic valve isn't just a re-purposed nitrous solenoid. Nitrous valves pull too much current, have tiny little 1/8" NPT ports, and don't flow nearly enough. Other similar industrial valves can't function reliably under high enough pressure to be useful or have seals/seats that are incompatible with methanol or nitromethane.

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! Also available in a normally open version for enrichment purposes.

The aluminum block is hard anodized for long life. The assembly includes a brass "pill holder" fitting that accepts Enderle screw-in bypass pills and -6AN fittings to attach a supply and return hose. Three pills (50, 55, 60) are included to get you started.

The coil can be rotated to position the non-polarity sensitive leads in any direction desired. The slots in the valve body allow bolting the 1.25" thick block to the vehicle with 1/4" screws 1 5/8" apart.

As a high-speed lean out, this valve can be activated with an RPM activated switch or timer when needed to take fuel away at the top end for best horsepower.

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 AFR is difficult to tune.

This valve comes default with gas and methanol compatible seals. If nitro safe o-rings are required, please specify in the notes section of your order.

Very soon, we'll be offering up to 4 of these valves in our very own manifold configuration!
