Grimmspeed Boost Controller Solenoids

The GrimmSpeed Boost Control Solenoid is designed to work with your factory computer (requires tuning). It will not reduce the life of your factory computer because it is designed to draw the same ammount of power as the factory BCS but flows better and reacts faster. It plugs in and requires no splicing or soldering of resistors. With the included bracket you can bolt it in, plug in the connector, and start tuning for fast boost response, increased boost pressure and free up lots of power. Planning on returning the car to stock? Just reverse installation.

Why run an Electronic BCS over a Manual Boost Controller? A MBC allows you to run higher than stock boost levels by preventing the wastegate from opening at its rated pressure. It does a great job at this but if boost is available under the MBC setting it will give you that full boost. So for instance, you set your MBC to 18psi because from 3000-6000rpm thats what you want. But then say you get detonation with 18psi when you are at 7000rpm unless you are below 16psi. With a MBC, you do not have this control so you are forced to run 16psi through the entire rev range. With an electronic boost controller you could run 18psi from 3000-6000 and 16psi at 7000rpm because you can tune the boost map in the ECU which will allow you to run the maximum amount of boost at every given rpm. This gives you more power throughout the range and better control. Revolutionizing the boost solenoid market, they have created model specific install brackets that allow you to directly fit the Boost Solenoid into your car for a factory fit. No more Zip-tying! They give you the factory fitment you have been waiting for.

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

Also new to the boost solenoid market, they 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!

Features:
  • Get into Boost Much Quicker (Flows 10% more than the competition)
  • Plug and Play into OEM Harness (no splicing wire like other BCS!)
  • Factory Fit with clean install
  • Works Safely with Factory ECU (custom coil to match ECU)
  • Nickel Plated Fittings as this is Built To Last (not the easily breakable plastic fittings!)
  • Easy to Install and Very Easy to Tune
  • The Only Direct Bolt-IN BCS on the market
  • Users can use AN fittings with the solenoid.
  • MAC Valve has completely custom made the valve for them (only MAC valve on the market to be custom made for automotive tuning use).
  • Specifically designed by GrimmSpeed to work safely with the factory ECU (requires tuning) and to reliably handle the vibrations and temperatures of your engine bay!
  • The only direct bolt in design on the market. Direct bolt in mounting bracket and hardware included! (specify which model before ordering)
  • 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)

Tuner's comments on our Boost Solenoid
  • AWD Tuning:
    "The GS 3-port BCS 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. "


  • 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. 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."
