Performance Focused: Turbosmart’s Kompact Shortie BOVs/BPVs for 2016 Ford Focus RS

With the latest Focus RS, Ford has created one of the most fearsome performance hatches ever made, unashamedly targeting big players like Mercedes’ CLA45 AMG and the VW Golf R. With its 2.3-liter EcoBoost engine, the Focus creates some serious boost and power – which is great for performance, but it puts added stress on the components within the turbo system.

The Kompact VR08 Blow-Off Valve for the Focus RS has been developed with the Focus’s high boost pressure in mind, with the goal to improve performance and durability. Plastic OEM blow-off valves like those on the RS have a track record of failures – they leak, and they become brittle with age until they eventually crack, causing serious problems. Producing around 23 PSI of boost pressure in standard form, the Focus is already pushing the boundaries of its standard plastic blow-off valve – and there’s not much room to turn the boost up before the standard valve will struggle to keep up.

Turbosmart’s Kompact is constructed of billet aluminum, rather than plastic. Its brass piston is both strong and light, and each BOV is individually matched with the right piston to ensure the best fit, meaning there’s no need for an O-ring to seal the body against the piston. This gives the Kompact unsurpassed durability and responsiveness, with less maintenance required than aftermarket BOVs that use piston sealing O-rings.

The Kompact for the Focus RS can be had in both Dual Port and Plumb Back versions. The Plumb Back is a fully recirculating blow-off valve that offers a similar sound volume to the standard valve, so you can have all the performance of a Turbosmart blow-off valve, while flying under the radar. The Dual Port features a split operation between recirculating and venting to atmosphere, providing quiet operation at low boost, and head-turning vent-to-atmosphere sound at high boost – a great complement to the Focus’s rally fighter character. The Kompact for the Focus RS features enlarged ports compared to previous versions, giving the RS the flow it needs.

These direct replacement blow-off valves offer an easy performance improvement without the need for custom fabrication or special tools. It’s yet another addition to Turbosmart’s ever expanding range of parts for Ford’s latest EcoBoost range of vehicles.

86 Build Blog, part 2: The Boostening

If you missed part one, read it here! 

A few weeks ago, we introduced you to our Toyota 86 long term development car. We set about transforming our bone stock 86 GTS into something a bit more special, beginning with the groundwork – a good suspension setup, bigger wheels, sticky tires, and an aftermarket ECU. The result was a good looking car that handled nicely, but there was still an elephant in the room.

The 86’s powerplant was still untouched. The FJ20 boxer four remained completely stock, and this was concerning – because we’re not called Aspiratedsmart.  If there was any doubt to what was going to happen to the 86, we’re clarifying it now: this car will, of course, be turbocharged – like it should have been from the factory!

Well, if the factory did it, they’d be doing it a bit differently to this. Our build is a bit on the extreme side, and there will be some things on this car that you have never seen before. The reason for this is simple – this car is meant to be a development test bed. We’re not chasing outright power, but more a platform on which we can put our parts to work.

The customised kit was the work of Sydney Motorsport Engineering. These guys put in some serious hours to get the whole kit built just how we wanted it – complete with some requests that would make a lot of kit builders run for the hills. The result is a very unique design, with plumbing for multiple external wastegates and over 40 sensors that we use to keep an eye on everything the 86 is doing.

One of the more unique aspects of our setup is the vehicle’s three wastegates. Yep, there’s three of them. The turbo retains its internal wastegate, then there’s an external ‘gate mounted just before the turbine housing, and another external ‘gate on the headers.

So, how does it all work? Well, the internal wastegate and first external ‘gate are both fully functional, however only one can operate at a time. The third wastegate is independent of boost, instead operated by an air compressor in the boot of the car. It’s purely there for duty testing, to make sure our products are as durable as possible. We’ll look at this setup in more detail later.

All those wires hanging down are for the various sensors to talk to the ECU and log data. Getting the spaghetti of wiring running neatly will be a challenge, but not one beyond Chris, our engineer in charge of the build.

While the bulk of the work is done, there’s still a plethora of little jobs before the 86 is ready to get back on the road.

Stay tuned for part three, where we will see it all come together.
