The Kompact Shortie Blow-Off Valve for the Focus RS has been developed with the Focus’s high boost pressure in mind to improve performance and durability. Plastic OEM blow-off valves like those on the RS have a track record of failures – they leak and 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 struggles to keep up.
Turbosmart’s Kompact Shortie is constructed of billet aluminium rather than plastic. Its brass piston is 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 Shortie unsurpassed durability and responsiveness, with less maintenance required than aftermarket BOVs that use piston-sealing O-rings.
The Kompact Shortie 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 the 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 Shortie for the Focus RS features enlarged ports compared to previous Shorties, giving the RS the flow it needs.
These direct replacement blow-off valves offer an easy performance improvement without needing 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.
