The Kompact Shortie BOV for the Focus RS was designed with the Focus's high boost pressure in mind to improve performance and durability. OEM plastic BOVs, like those on the RS, have a track record of failure - they leak and become brittle with age, eventually cracking and causing serious problems. With a boost pressure of around 23 PSI in standard form, the Focus is already reaching the limits of the standard plastic BOV - and there's not much room to increase boost pressure before the standard valve can no longer keep up.
The compact shortie from Turbosmart is made of billet aluminium and not plastic. Its brass piston is strong and lightweight, and each BOV is individually matched to the correct piston to ensure the best fit, meaning no O-ring is needed to seal the housing against the piston. This gives the shortie unrivalled durability and responsiveness with less maintenance than aftermarket BOVs that use O-rings to seal the piston.
The Kompact Shortie for the Focus RS is available in Dual Port and Plumb Back versions. The Plumb Back is a fully recirculating BOV that offers similar volume to the standard valve, allowing you to utilise all the power of a Turbosmart blow-off valve while flying under the radar. The dual port valve offers split operation between recirculation and venting to atmosphere, allowing for quiet operation at low boost pressure and a stunning venting sound at high boost pressure - a great complement to the rally character of the Focus. The Kompact shortie valve for the Focus RS features enlarged orifices compared to previous shorties, giving the RS the flow it needs.
These direct-replacement blow-off valves offer an easy performance upgrade without the need for customisation or special tools. It's another addition to Turbosmart's ever-growing range of parts for Ford's latest EcoBoost range of vehicles.
The Turbosmart Compact Shortie VR08 fits the 2016 Ford Focus RS. This easy-to-install replacement for the fragile OEM plastic blow-off valve provides improved turbo response and reduces supercharger surge.
