General Production Information:
GrimmSpeed introduces the most complete and easy to use 3-Port Electronic Boost Solenoid available on the market. Our aftermarket boost controller allows you to raise the OEM boost levels in a quick and efficient manner. If you try to raise the boost on the weak OEM boost solenoid it will start to become unpredictable and unable to maintain proper and safe boost levels. Using our solenoid you are able to spool

 

your turbo quicker and maintain a rock solid boost level. We have made our solenoid to withstand 120psi, way more than any Subaru will see.

Revolutionizing the Subaru boost solenoid market, we have created model specific install brackets that allow you to directly fit our Boost Solenoid into your Subaru for a factory fit. No more Zip-tying! We give you the factory fitment you have been waiting for.

Staying with the OEM fitment theme, our Boost Solenoid uses a Subaru style wiring harness so you can simply unplug your OEM solenoid and plug ours in. No more cutting the oem wiring and crimping wires together!

Also new to the Subaru boost solenoid market, we have used ultra low-profile hose fittings to keep the unit as small and clean as possible. The hose fittings are nickel plated brass so you don't have to worry about them snapping off like the plastic hose fittings!

Full Features:

  • Direct plug and play into oem wiring.
  • MAC Valve has completely custom made the valve for us(only MAC valve on the market to be custom made for automotive tuning use).
  • Users can use AN fittings with the solenoid.
  • Mounting bracket so its a direct bolt on into factory location.
  • Low-profile brass hose fittings(small in size so its compact, no chance of breaking fittings like the plastic ones our competitors use).
  • Specifically designed by GrimmSpeed to work safely with the factory Subaru ECU (requires tuning) and to reliably handle the vibrations and temperatures of your engine bay!
  • The only direct “bolt in” design for all Subaru models. Direct bolt in mounting bracket and hardware included! (specify which model before ordering)
  • Includes plug and play harness, no wire splicing required and easy to return to stock.
  • Allows you to raise the factory boost levels with adding more response and more control.
  • Allows you to get full boost sooner.
  • Faster response and greater flow than any other valve out there. (by more than 10%!)
  • Nickel plated brass fittings. (unlike the competitors failure prone plastic fittings)



This BCS will handle all your boost control needs no matter what your power goals are.

Easy for your shop or tuner to tune! (Engine tune is required!)

Tuner's comments on our Boost Solenoid
AWD Tuning:
"The GS 3 port boost control solenoid provides rapid boost response while maintaining the ability to make acute adjustments via turbo dynamics. While many other boost control solenoids react to adjustments too fast which can make them difficult to control with as much finesse as the stock bleed system. This solenoid can make micro-adjustments at the edge of target boost not only providing better spool, but overall more control. Additionally, the solenoid is plug n' play so you do not have to splice into the wiring harness for it's installation. "

Bullwinkle Tuning:
"The GrimmSpeed BCS is a compact, well designed unit. Its design as a 3-port solenoid provides better boost control then the stock bleed-type style. The unit is easy to tune for, as it behaves like many of the other 3-port solenoids already on the market.

Often, this enables a tuner to cut mapped wastegate duty cycles in half. This change in WGDC gives a tuner more granularity when tuning, and can yield much improved boost curves. In addition, the 3-port design often significantly improves spool.

Lastly, the GrimmSpeed BCS is almost silent when acting in the engine bay, unlike some of it's competitors. A great product, one I would recommend."
