  • Turbosmart Ford Fiesta 1.0 EcoBoost | Kompact Dual Port Valve - Car Enhancements UK

    Turbosmart Turbosmart Ford Fiesta 1.0 EcoBoost | Kompact Dual Port Valve

    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.

  • GFB DV+ Fiesta ST180 - Car Enhancements UK

    GFB GFB DV+ Fiesta ST180

    The new DV+ GFB’S DV+ SOLUTION COULDN’T BE SIMPLER - KEEP WHAT WORKS AND REPLACE WHAT DOESN’T. Uses factory solenoid coil for seamless integration Replaces plastic valve parts with metal for reliability and strength on chipped engines Direct-fit replacement with GFB’s TMS benefits Exclusive “pilot-actuated” valve mechanism for rapid response at high boost GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great- the ECU opens it faster than any pneumatic valve so why replace it? The weak point however, is the valve mechanism itself. GFB’s DV+ solves this problem by replacing the valve parts with an anodised billet aluminium housing, fitted with a brass piston machined to exacting tolerances. The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Read all about the DV+ story below. Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve. This approach requires long vacuum hose runs, additional parts for tapping into the intake manifold vacuum, plus a different solenoid valve to actuate the pneumatic valve, or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install. GFB’s DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn’t cause compressor surge/ turbo flutter. Oh, and it doesn’t require different springs or frequent re-builds either. GET BETTER PERFORMANCE, FASTER BOOST RECOVERY AND DON’T PAY FOR WHAT YOU DON’T NEED! The DV+ story: Better performance - more reliable Many late-model European cars use ECU controlled solenoid-type diverter valves. This is a good concept because the valve can react very quickly and it only opens when it needs to. However, there are some problems with these valves; The diaphragms are weak and known to rupture, especially if boost has been increased. Once this happens, the valve will no longer hold boost pressure.The plastic lip that surrounds the diaphragm is very thin and pieces can break off, potentially ending up going through the turbo. Additionally, the solenoid on the OE diverter is directly connected to the valve mechanism, which is not ideal because neither it nor the return spring are strong enough to open and close the valve reliably at high boost. With problems like this, you can see why other aftermarket manufacturers assume the best solution is to replace the factory diverter entirely, or change it to a purely pneumatic system. Unfortunately though, whilst their replacement kits might be stronger than the factory diverter, their slower response speed and lower flow do not justify the extra cost and complexity - more of a compromise than a solution. GFB has taken a different approach to deliver a complete solution that solves existing problems and improves performance, without compromise or a hefty price tag. The DV+ addresses the factory valve problems with a very simple and elegant solution. Keeping the factory solenoid, the DV+ retains all the benefits of the stock system. Also replacing the valve parts with indestructable metal components ensures strength and reliability, no matter how much boost you run. That’s not all; rather than using the solenoid to directly actuate the valve, we’ve introduced a unique “pilot-actuation” system. This means the solenoid only has to control airflow through a small passage that is then used to open and close the piston (rather than opening and closing the piston directly), so it doesn’t matter how much boost you push through it, the DV+ will open and close reliably without ever exceeding the solenoid’s capability. This feature also improves on the factory system by opening the valve progressively in response to boost pressure, so it only opens as much as required to get the job done (the factory valve simply opens and shuts, it cannot partially open if boost pressure is low), resulting in better throttle response. Unnecessary replacement kits are a compromise, not a solution

  • Turbosmart 1.0 EcoBoost Uprated Recirculating Valve - Car Enhancements UK

    Turbosmart Turbosmart 1.0 EcoBoost Uprated Recirculating Valve

    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.

  • GFB VTA - MK8 Fiesta ST - Car Enhancements UK

    GFB GFB VTA - MK8 Fiesta ST

    The VTA is a performance blow-off valve solution for Fiesta MK8 ST vehicles with an electronic factory diverter valve.   If you want sound with your performance (or performance with your sound!), GFB’s VTA delivers just that! By combining the proven performance benefits of our ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions. The VTA shares the successful DV+ design philosophy: “Keep what works, replace what doesn’t” This means we retain ECU control and the solenoid from the factory diverter to ensure the fastest possible response time, without the added and unnecessary cost of replacing the solenoid like some brands do. The weak part of the factory diverter has always been the plastic valve mechanism – this is the part we replace. The VTA features CNC machined billet components that last a lifetime, and we also change the valve operation method for better performance. The factory diverter valve can only operate in two states – open, or closed. When it opens fully at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition. GFB pioneered the use of “pilot operation” in the DV+, which works by re-purposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force. More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve. It is this design philosophy that makes the VTA not only the best performing blow off valve solution, but also the best value on the market.  Key features: TMS Technology for faster boost recovery on gearshift and during throttle modulation Improved boost holding ability Atmosphere venting for blow-off sound Retains ECU control Simple, direct bolt-on kits include everything you need to install Manufactured in Australia in accordance with ISO 9001  VTA or DV+?  Depends if you want sound or not. Both valves are constructed with the same quality materials and valve mechanism, and both offer the same performance and reliability benefits. However, the VTA vents to atmosphere for sound whilst the DV+ recirculates the air to keep it quiet. Why choose a VTA over a “BOV spacer”? “BOV spacers” are cheap and they make sound. But that’s it. All the inherent performance and reliability issues you get with the factory diverter valve remain, because a spacer doesn’t change the diverter valve in any way. The VTA improves the operation of the diverter valve for sound AND performance. Why choose a VTA over a kit that includes a solenoid? Because there’s no performance benefit to replacing the factory solenoid, only a much higher price! If a VTA with the factory solenoid can open in a couple of hundredths of a second, why pay more than you need to?

  • GFB T9454 VTA for Ford Focus ST (MK2 & MK3) and Borg Warner Turbos - Car Enhancements UK

    GFB GFB T9454 VTA for Ford Focus ST (MK2 & MK3) and Borg Warner Turbos

    Fits the following vehicles Ford Focus MK2 ST225 Ford Focus MK2 RS Ford Focus MK3 ST250 If you want sound with your performance (or performance with your sound!), GFB’s VTA delivers just that! By combining the proven performance benefits of our ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions. The factory diverter valve commonly found on these turbos has two distinct issues – reliability, and performance. Oh yeah, it also doesn’t make any noise. Here’s how the VTA addresses these problems. Reliability – There are two ways in which the factory diverter valve can fail; the un-reinforced rubber diaphragm can rupture, and the metal valve stem that slides in the plastic cap can stick. In both cases, there is a risk to the turbocharger, as the ECU will attempt to compensate for a boost leak by increasing the wastegate duty cycle, which increases the turbo RPM significantly. The VTA features CNC machined billet components that last a lifetime and cannot be damaged by high boost pressures or the associated increased charge temperatures. Performance – The factory diverter valve typically operates in only two states – either fully open, or fully closed. When it opens at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition, which is noticeable as a distinct “step” down in power as you roll off the throttle and the valve opens. The VTA however allows the piston to open and close progressively in response to the amount of boost pressure present, so it only vents enough air to prevent compressor surge (the primary purpose of a diverter or blow off valve). This helps to smooth out boost transitions, making the throttle response more linear and predictable, and also minimizes lag introduced by the factory diverter valve.   VTA or DV+?Depends if you want sound or not. Both valves are constructed with the same quality materials and valve mechanism, and both offer the same performance and reliability benefits. However, the VTA vents to atmosphere for sound whilst the DV+ recirculates the air to keep it quiet. Why choose a VTA over a “BOV spacer”?“BOV spacers” are cheap and they make sound. But that’s it.
