Introducing the SteamSpeed 3-Port BCS

Tuners strongly recommend them; we recommend them.  Now we make them:  Introducing the SteamSpeed BCS (boost control solenoid aka EBCS) plug and play for all turbocharged Subaru models.

Our 3-port boost control solenoid provides super high resolution boost control to dial in much more accurate tunes vs. the old OEM 2-port solenoid.  Our BCS provides your tuner the tool need to safely dial in the correct boost levels, and achieve the best results possible.   At the heart of our BCS is a super reliable industrial valve that is more responsive, higher flowing, more durable than stock.  With our high performance BCS valve,  your turbo will spool quicker, and maintain the tightest possible boost curve.

We include everything you need in the box for plug and play install.  It mounts right to the stock location without modification with our custom made brackets, and clips right into the wiring harness.  We even include new silicon vacuum lines and bolts so no extra trips to the parts store is needed.

We have used the GrimmSpeed BCS on our cars in the past, and they have worked great.  Tuners we have worked with in the past recommend them, so we used their product as a measuring stick.

For our test, we simply swapped out the GrimmSpeed BCS and hooked in the vacuum lines in the exact same ports and swapped their connector for ours into the wiring harness.

How did it work out?  Not surprisingly, they worked basically the same since they both are based off of nearly identical MAC industrial valves.  In our testing, our higher flow barb option did out flow the GrimmSpeed BCS by about 20%.  Our standard barb option flowed exactly the same.  In fact, in our testing, the boost curves were identical with both BCS.

This is how our EBCS was hooked up to the waste gate.
