Raceworks is a range of High Performance AirFuel, and Fluid Management Components.

Raceworks products are manufactured from premium quality materials to ensure the highest specifications and industry standards are surpassed.

Raceworks components include fuel pumps, silicone hoses, fuel rails, aluminium fittings, performance hose, fuel injectors, sensors, connectors and supporting hardware.

Raceworks is available through a network of specialised resellers and leading automotive retail groups who have a passion for performance.

Pro Speed Racing now offer fuel rail packages including Torque Solution top-feed fuel rails and quality Raceworks hoses and fittings. This kit can suit any Twin Inlet 1/8" NPT Fuel Pressure Regulator including the Turbosmart FPR800 and GFB FX-S.

Torque Solution Top Feed Fuel Rails are a must have for high horsepower applications and a perfect complement to your high flow fuel injectors. Our rails are made from 6061 Billet Aluminum with a 5/8" ID for maximum fuel flow and threaded for -8 O-Ring boss fittings (not included). Perfect for setting up your fuel system in parallel to ensure each cylinder receives optimal fueling. All our rails come anodized with our logo engraved into the billet to look as good as they perform. Zinc install hardware is included to prevent rusting.

This kit incorporates the Raceworks 200-Series E85 safe braided hose in either stainless steel braid or black braid. Raceworks 200 Series Teflon Braided Hose is constructed from a PTFE (Teflon) inner tube that is compatible with all fuels, oils, nitrous including brake and clutch fluids. The PTFE (Teflon) tube is covered by a stainless steel outer cover that is durable, and resistant to abrasion and expansion. The Raceworks 200 Series Hose is the best option for use on fuel systems as it won’t allow the permeation of fuel smell, and has the highest pressure and temperature rating in the range of Raceworks hoses.

Raceworks 200/220 Series Hose Ends are all manufactured from 6061 T6 grade billet aluminium. All Raceworks hose ends are hardcoat anodised for maximum protection, and full flow to provide uninhibited fluid movement. Female swivel hose end ensures ease of fitment once 200 Series Hose has been connected. All Raceworks products come with a 2 year warranty.


Fuel Pressure Regulator Options:


Whether you run pump petrol/gasoline, Ethanol, Methanol or Diesel, a single small pump or a massive triple setup, the GFB FX range has you covered no matter what your Fuel Pressure Regulator requirements are. 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 range.

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 GFB, 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 1000psi! The multiple inlet/gauge ports also 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.

Turbosmart FPR800 -

Turbosmart's newest High-performance EFI fuel pressure regulator is smaller, lighter and better! Now featuring two 1/8" NPT inlet ports, one 1/8" NPT return port and 1/8" gauge port, 30-90 PSI base pressure adjustment, 1:1 ratio, premium diaphragm and stainless steel valve seat allow for ANY fuel type including E85 and is suitable for engines with up to 800hp fuel systems. FPR's feature a non-directional bias to regulation, so no matter where the fuel comes in they will regulate the same. Factory tested.

All Turbosmart FPRs are CNC machined in house from billet aluminium stainless steel and hand-assembled and tested to ensure maximum precision. Turbosmart FPR’s have been designed to provide smooth and stable fuel pressure delivery under all conditions from idle to full throttle and are suitable for use with both electric and mechanical fuel pumps. The FPR range features an easy screw and lock adjustment and provide a stable 1:1 ratio between fuel pressure and manifold pressure. Each FPR is backed by a variety of accessories such as fuel rail adapters, gauges and fittings to suit most popular makes and models.
