Grimm speed boost solenoid install

The WRX offers a unique change of pace, as the factory 2-port solenoid is mounted directly to the plastic turbo inlet and interfaces with an o-ringed feature, rather than a vacuum hose, but, if you're running an aftermarket turbo setup, you may no longer be utilizing the factory turbo inlet.

This product includes the solenoid with fittings and connector, as well as a universal mounting bracket, rather than the machined adaptor required by the factory turbo inlet. We've also left the wiring harness longer to facilitate a number of different mounting locations, depending on your turbo setup.

The advantages of a 3-port boost control system vs. The 3-port systems works by interrupting the boost signal traveling from the turbo to the wastegate. The factory configuration simply 'bleeds' the signal from between the turbo and wastegate, which creates a system that is a bit less complex, but reacts more slowly and with less precision. The chart above shows two boost plots. The 'before' is our WRX, dyno tuned by a third party protuner. This is safer for your car and easier for your tuner.

With tens of thousands on vehicles across the world, tuners trust it and our customers love it. Because this upgraded solenoid affects the way that your vehicle controls boost that's the point!

It is not recommended that you drive the car in a way that builds boost without doing so. 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. 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 rpm thats what you want.

But then say you get detonation with 18psi when you are at rpm 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 and 16psi at rpm 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 EVO boost solenoid market, we have created model specific install brackets that allow you to directly fit our Boost Solenoid into your EVO for a factory fit. No more Zip-tying! We give you the factory fitment you have been waiting for.

No more cutting the oem wiring and crimping wires together! Also new to the EVO boost solenoid market, we have used ultra low-profile hose fittings to keep the unit as small and clean as possible.

GrimmSpeed has become the most trusted brand in the BCS market, with tens of thousands of their boost control solenoids in operation today across the globe. Availability date:. This product is not sold individually. You must select at least 1 quantity for this product. The advantages of a 3-port boost control system vs.

The 3-port system works by interrupting the boost signal traveling from the turbo to the wastegate. That boost is redirected back into the turbo inlet and re-ingested by the turbo using the machined adapter.
