A blowoff valve (BOV), dump valve or compressor bypass valve is a pressure release system present in most modern OEM road car applications. Its purpose is to prevent compressor surge / stalling and reduce wear on the turbocharger. These control valves remove the damaging impact of ‘surge loading’ by allowing the compressed air to vent  away from the compressor wheel. This discharge can be heard as a distinct ‘dump valve’ hissing sound as it vents to atmosphere or back into the intake depending on the application and ECU airflow regulation. The Fiesta 1.0T Ecoboost uses an inexpensive electronic diverter valve as standard which is prone to failure and inconsistent results when used at higher boost pressure.Plumb Back Kompact Shortie Kit for Ford Fiesta 1.0TStock blow-off valves like those that come standard with the Fiesta 1.0 often suffer from a range of problems. They are plastic, and they leak, and if you want to up the power (who doesn't?) they have trouble holding the extra boost. You’ll have no such troubles with Turbosmart’s Kompact Shortie blow-off valve. Like all Turbosmart blow-off valves, the new Fiesta 1.0 Kompact Shorties have been designed, machined and hand assembled in-house. Keeping the process in-house, ensures only the best quality, and the aircraft grade aluminum alloy construction means cracking and leaking even under increased boost levels will never be an issue. The Fiesta 1.0 Shortie is produced with a light-weight, brass/aluminium, two-piece piston, which is then perfectly matched with precision engineered springs, giving razor sharp valve response, and a serious increase in performance over stock valves.  Will fit both, Fiesta 1.0 Ecoboost and Focus 1.0 Ecoboost.

Turbosmart's new Kompact VR09 Dual Port for the 1.0-litre EcoBoost is a billet aluminium replacement for the Fiesta's factory plastic BOV.The Dual Port is a 50-50 recirculation/vent-to-atmosphere valve for that classic vent-to-atmosphere BOV sound at high boost, and quiet operation at low boost. The standard bypass valve on the 1.0-litre EcoBoost engines is a weak, plastic, diaphragm-type valve - a type of valve that has a track record of failures. Turbosmart's billet aluminium replacement is manufactured with precision, designed for unlimited boost holding capability, excellent response times and heavy-duty reliability.The Fiesta's standard valve is controlled by a solenoid, meaning the ECU can decide when to open the valve - meaning it can be used to bleed boost, limiting performance. The Turbosmart VR09 Kit bypasses this solenoid, allowing the BOV/BPV to operate with manifold vacuum, putting control back in the hands of the driver, all with no check engine lights.Installation is straightforward, and the valve is a bolt-on direct replacement for the factory valve. No special tools are required and all necessary hardware is included.The Kompact VR09 is precision machined, hand assembled and individually quality tested in Australia to the highest quality standards.
