GO FAST BITS FX SERIES EFI FUEL PRESSURE REGULATORS JOIN OUR EXISTING
LINE OF SUCCESSFUL PRODUCTS, BUILT WITH THE SAME PRECISION, MACHINING
QUALITY, AND RELIABILITY THAT IS THE FOUNDATION OF OUR REPUTATION.
From the 800Hp FX-S Street to the 1500Hp FX-R Race version, and
whether you run pump petrol/gasoline, Ethanol, Methanol or Diesel, we
have you covered no matter what your Fuel Pressure Regulator
What sets us apart from the competition? Well, if you’re looking
for an EFI Fuel Pressure Regulator that seals and behaves just like
your factory unit but with the added reliability and high flowing
capacity you require, then look no further than the FX-S.
How have we achieved this? Our engineers have spent countless
hours developing a unique replaceable co-polymer valve seat. What does
this mean? Conventional aftermarket performance Fuel Pressure Regulators
typically utilize a metal-to-metal valve and seat which by nature will
not positively hold pressure when your engine is shut down, which can
make startup more difficult.
Here at Go Fast Bits, we have incorporated a softer, more compliant yet
resilient material for the valve seat, which will always positively seal
and hold fuel pressure on shut down, designed to give factory-like
sealing and reliable startup, as well as superior fuel resistance
suitable for Unleaded, Ethanol, Methanol, and Diesel fuels.
We also use a double layer diaphragm, which means we have twice
the reinforcing material, and as a result the burst strength exceeds
The FX-S also offers multiple fuel inlet and gauge ports that
allow for a wide range of fuel system setups beyond the usual
inlet/outlet, including parallel fuel rail or returnless “deadhead”
systems. The two gauge ports allow you to run a mechanical fuel pressure
gauge AND an ECU fuel
pressure sensor if you want to.
Go Fast Bits - http://www.gofastbits.nl Go Fast Bits started back in 1997 designing, testing and developing GO FAST BITS. Today a wide range of innovative and high-quality blow-off valves, boost controllers, pulley kits and short shifters are available. All meticulously designed and manufactured from the highest grade materials. GO FAST BITS products are manufactured in Australia and GFB is constantly developing new and innovative products!
Showoff Imports is the official distributor for GFB parts for the Netherlands and Belgium. Currently we stock all popular products, so no waiting times! Dealers inquiries welcomed.
What makes GFB blowoff valves different and better?
Our new TMS Turbo Management System don't throw your BOOST away but INCREASES IT BY up to 40%. GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves. We looked at the concept named ‘blowoff valve’ and took this to a whole new level! Basically the main benefits are:
MORE POWER - BETTER RESPONSE - BETTER DRIVE ABILITY - GET THE SOUND OR NOT.
How to choose a BOV
With the vast range of GFB blow-off valves, questions rise 'Which blow-off valve is the best?' and 'Which blow-off valve should I use?'
The first question is easy to answer: There isn't actually a 'best' in terms of quality. All GFB blow-off valves use the same high-quality internal components. So, provided the right BOV is fitted for your particular vehicle, they all offer the same performance benefits of improved throttle response and reduced lag. The real question is: How do you select the valve for you?
The first step to decide on 'your' BOV, is whether or not you want to hear it, and if so, how much? The following chart lists the “noise ratings” of our blow-off valve range. The final decision will then be based on how much control you want over the blow-off volume level.
GFB boost controllers use a more consistent needle-valve bleed system, which brings boost on just as fast as any ball-and-spring system, and generally more quickly than a factory boost control system. On the productpages you can find a comparison of the GFB controller to other major brands, guess who wins this standoff? GFB!
A GFB boost controller will give you the added benefit of not only being able to adjust the peak boost level, but in most cases will bring the boost on earlier, resulting in more power throughout the rev range.
The reduction in rotating inertia (we've removed about 2kg by using 6061 T6 aluminum billet) means that the engine can accelerate much quicker during the times it is making very little power before the turbo spools up. The result is better drive ability off-boost and better acceleration, which is especially useful for those with large turbos that only make power in the upper rev range. The smaller size of the crank pulley under-drives the power robbing accessories so that the upper end of the rev range is less burdened, while still allowing them to operate properly.
Short Shift Kits
The GFB Short Shifter is the same height as the factory shifter, it is the actual distance that the gear stick moves between gears that reduced.
Very simple to install. All of the installation is done from inside the car, without having to jack it up and crawl around underneath. Only a few basic hand tools are required, and the necessary hex keys are supplied.
The maximum throw reduction varies for different models. Early WRXs had a particularly long throw, so the maximum reduction with the GFB kit is around 50%, whilst on later models it is closer to 40%. In either case, it is possible to reduce the distance per gate to about 30mm. Whilst it can go shorter, the shifting force becomes too great for comfort, and some of the shift feel is lost.
