GFB

All the Performance with the Noise! The Hybrid valve is back! In 1999, GFB’s first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most other brands. By “staging” the two venting outlets, at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound. As a benefit, this system makes it possible to use these valves on cars with sensitive airflow meters that often suffer issues such as backfiring and/or stalling, whilst still achieving the signature blow-off sound. Dual staged venting outlets, can be configured for full recirc, 50/50, or full atmosphere operation using plugs provided TMS Technology for up to 30% faster boost recovery on gearshift Huge range of direct bolt-on kits 100psi+ boost holding ability Manufactured in Australia in accordance with ISO 9001   Complete Range of Fitment Options The Hybrid direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments.

European manufacturers are pushing their engines to the limit. Get a DV to match. GFB's DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles. By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-orientated product. GFB’s DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to “pilot actuation” to ensure better performance on stock or modified engines. Furthermore, these benefits won’t cost you the Earth! Rather than throwing the entire factory diverter valve system in the bin (like other manufacturer’s “solutions”), the DV+ keeps what works and replaces what doesn’t. It retains the factory solenoid and ECU control to ensure simple installation and reliable operation. 10% faster opening, 50% faster closing than the factory diverter Retains the factory solenoid for seamless integration Replaces plastic valve parts with metal for reliability and strength on stock or modified engines Direct-fit replacement with GFB’s TMS benefits Exclusive “pilot-actuated” valve mechanism for rapid response at high boost   Related Videos:

Boasting a repeatable and stable boost curve, quick rise rate, and unbeatable value, GFB’s Atomic has earned a reputation as being one of the most reliable and effective manual boost controllers on the market. It is important to note that the Atomic does NOT use a “ball-and-spring” system like others on the market, for very good reason. The ball-and-spring system is an attempt to increase the boost rise rate by preventing pressure from reaching the wastegate during spool up. However, in practice this method usually creates boost spiking and a less stable and repeatable boost curve. Instead, the Atomic uses a precision orifice and needle valve system to accurately bleed pressure from the wastegate line to increase boost. With no moving parts, this system is ultimately more reliable and stable. For use with any type of petrol/gasoline or diesel turbocharger system using a traditional pneumatic wastegate (internal or external).   GFB Atomic: Case Study The Atomic Boost Controller was tested on an MY02 Subaru WRX (whose only mods were a turbo-back exhaust) back-to-back with the factory controller.  A base-line power run was performed with the factory boost control, and the boost level was measured at the same time.  The Atomic was then installed and set to the same peak boost level of 0.9bar (13.2 psi) so that the spool-up time could be accurately compared before and after the installation. The dyno graph shows the Atomic boost curve in green, and the factory curve in blue. 4th gear is used for both tests, and proof that the Atomic was set to the same peak level is seen towards the end of the chart as the two curves meet.  However, notice the massive gains down low in the rev range, as much as 18kW (23.4hp) AT THE WHEELS! This increase in power shows that the Atomic allows the boost to rise significantly earlier than the factory controller, which on the road represents much better acceleration from a whopping 1700RPM earlier in the rev range.  All this WITHOUT exceeding the factory peak boost level, and for a pocket-money price! It is important to note that the MY01-02 (MY02-03 in the US, GDA chassis) model responds very well to this modification, because the factory boost mapping is very conservative in an attempt to keep the torque curve flat and the power delivery linear (which totally kills the feeling that you are driving a turbo!).  Note of course that boost can be increased above the factory level for more power gains, but the purpose of this experiment was only to show the improved spool-up potential on this particular model WRX. So, if you want your GDA WRX to REALLY feel lively, fit an Atomic or Reactor boost controller for the best “bang-for-your-buck” modification you can make!   Any form of boost control should be considered a tuning tool rather than a bolt-on power adder, and therefore adjustments should be done with knowledge of the limits of the engine/turbo to maximize the performance gains and reliability from using this product.       GFB Manual Boost Controller Features: REPEATABLE AND STABLE BOOST CURVE 100% RELIABILITY, ZERO MAINTENANCE EASY TO INSTALL IN MINUTES EASY TO ADJUST, SET-AND-FORGET PRECISION NEEDLE VALVE BLEED SYSTEM, MORE STABLE THAN “BALL-AND-SPRING” TYPES MANUFACTURED IN AUSTRALIA IN ACCORDANCE WITH ISO 9001 Manual Boost Controllers may lack the extra features of an EBC (Electronic Boost Controller), but they get the job done! When you need simple, reliable, set-and-forget boost control, a Manual Boost Controller is hard to beat. Installation is as simple as connecting a couple of hoses, and setup is as easy as turning the adjustment until you hit your target. Once that’s done, you can forget about it and drive your car. Being a rugged, mechanical device, it will never vary or fail, no matter how much abuse you can throw at it. Our Manual Boost Controllers are available in two types, one is suited for conventional pneumatic wastegates, and the other is for use with vacuum-actuated VNT (Variable Nozzle Turbine)/VGT (Variable Geometry Turbine) turbos that are commonly used on diesel engines.     ONLY COMPATIBLE WITH:     Holden COMMODORE       Mazda 3 6 CX-7 MX-5       Mitsubishi 3000 GT COLT ECLIPSE GTO GALANT LANCER STARION       Nissan 180 SX 200 SX 300 ZX PULSAR SKYLINE       Subaru FORESTER IMPREZA LEGACY       Toyota CELICA SOARER SUPRA

All the performance with or without the noise! If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues. Like all GFB valves, the Respons utilises GFB’s proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce. How GFB’s patented venting bias adjustment works Twisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere and anywhere in between.

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. All the inherent performance and reliability issues you get with the factory diverter valve remain, because a spacer doesn’t change the factory diverter components or operation method in any way. The VTA improves the operation of the factory diverter valve for sound AND performance.
