GFB Mach 2 Atmosphere Conversion Kit

MACH 2 ATMOSPHERE UPGRADE KIT TO CONVERT T9120 FROM RECIRCULATING TO ATMOSPHERE VENTING BOV. CONSISTING OF TRUMPET, SPRING AND PLUG. There is a harder spring supplied in this kit, as the valve needs to remain closed at idle when venting to atmosphere. This prevents stalling and backfiring.

GFB Whistling Trumpet 5702

You asked, we delivered. Many times we have been asked for a replacement trumpet that gives a different sound, and here it is. The ability to change the sound of a blow-off valve is increasingly becoming an important issue with buyers, who want to sound different from everyone else. In 2004, GFB released the Whistling Trumpet (part # 5701), which emitted a piercing screech when driving aggressively. Unfortunately for a number of GFB owners, the 5701 trumpet only worked with some valve types. For the owners of all other types of GFB valves, we have now released the 5702 â a modified version of the Whistling Trumpet that is designed to work on low boost applications where the 5701 doesnât cut it. The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch. Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet â Respons valves will typically not generate the velocity required to whistle when set to 50/50 venting. This part is recommended for Respons and Deceptor Pro II valves EXCLUDING T9003 & T9503

GFB Atomic Single Stage Boost Controller

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 StudyThe 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.
