Inlet manifold pollution is a common issue for modern diesel engines, particularly the high-efficiency Common Rail systems found in current 4x4 vehicles. To counter this, Process West developed the SEPR8R, an advanced catch can system that utilises industrial-grade filtration to protect your engine’s intake tract.

Design Philosophy
The core of the SEPR8R system is a precision-engineered internal filtration unit. It is designed to intercept oil-polluted air venting from the rocker cover and "scrub" the oil mist from the gas before it recirculates into the inlet manifold.

From the factory, this filtration typically does not occur. This allows oil to accumulate in the intercooler and intake piping, which can result in reduced engine performance and diminished fuel economy over time.

Installation and Fitment
The SEPR8R is designed as a complete, bolt-on kit tailored to specific vehicle models. Each kit is engineered to integrate seamlessly into the engine bay with a factory-level finish.

Vehicle Specific

Includes laser-cut brackets designed for a perfect fit in your specific engine bay.

Plug-and-Play Hoses

Supplied with molded, temperature-resistant hoses shaped specifically for the vehicle, ensuring a tidy installation without universal "looping" lines.

Our fuel anti-surge system is the ultimate in fuel delivery for your turbocharged Falcon.

In September of 2007 Process West released a bar-raising true plug and play anti-surge system for the BA/BF Falcon. In 5 and a half years we sold more than 1500 units and it became the bench mark for fuel delivery in modern turbo Falcons.

The original system was based on a billet surge vessel with an externally mounted Bosch Motorsports 044 pump. Now in March of 2013 we have raised the bar once again. It was time to modernise the product and bring it up to date with the requirements of modern car fueling and fuel types.

The new system sees the pump (or pumps) mounted internally to an externally mounted anti-surge vessel. The vessel is mounted to the chassis rail just like the original Process West anti-surge system... this is not an in-tank system.

One of the main objectives when designing the system was making sure the system was easily upgradable when the need for higher fuel flows is required. The "basic" system comes installed with 1 x Walbro 460LPH pump and is a simple plug and play option.

A second Walbro 460 can be easily added to the system either at the time of purchase or later down the track when the demand for greater fuel supply is required. We have a package that allows the second pump to be installed along with a Turbosmart FPR1200 fuel pressure regulator and all of the necessary hardware for easy installation with the factory fuel rail.

Alternatively if you have an aftermarket dual entry fuel rail we have a complete fitting kit including Turbosmart FPR1200 regulator.

Assembling a fuel delivery system to suit your requirements

The "basic" single Walbro 460 system will satisfy the fuel delivery requirements of 90% of applications. This single pump system will support 680 rear wheel kilowatts and is a simple plug and play system.

When a second pump is added to the system the flow is greatly increased and the factory fuel pressure regulator is unable to control fuel pressure. At this point we need to address fuel pressure control.

What we have done is put together a package that allows the factory fuel rail to stay in place and add a Turbosmart FPR1200 fuel pressure regulator to the system. This package is known as the Process West Stage 1 Fitting Kit.

The stage 1 fitting kit combines the outlets of the two pumps, provides a factory fuel pressure regulator by-pass plug, a Turbosmart FPR1200 regulator + all of the fittings to complete the installation.

If you have an aftermarket duel entry fuel rail then we have the Process West Stage 2 Fitting Kit. This kit keeps both pump outlets separate, utilizes -6 (3/8in) hose size throughout, AN Speedflow fittings and the Turbosmart FPR1200 fuel pressure regulator.

When purchasing a twin pump system it is worth noting that the system concludes at the pump outlets of the surge tank. From this point on you will need one of the fitting kits or if you wish you can source the fittings/hoses etc and plumb it up yourself. You can spec the system with either 5/16 hose tail barbs or -6 AN type fittings...

Our fuel anti-surge system is the ultimate in fuel delivery for your G3 WRX or STi.

In early 2008 Process West released a true plug and play anti-surge system for the MY97 to MY07 WRX/STi. We sold many 100s of these units in the last 4 years.

The original system was based on a hand fabricated surge vessel with an externally mounted Bosch Motorsports 044 pump. Now in October of 2013 we have raised the bar. It was time to modernise the product and bring it up to date with the requirements of modern car fuelling and fuel types.

The new system sees the pump (or pumps) mounted internally to an externally mounted anti-surge vessel made from  6061 billet aluminium. The vessel is mounted just above the transmission cross member. This is not an in-tank system.

One of the main objectives when designing the system was making sure the system was easily upgradable when the need for higher fuel flows is required.  The “basic” system comes installed with 1 x Walbro 460 LPH pump and is a simple plug and play option. Alternatively we offer a twin Walbro 460 system.

Features

• 2.4 litre capacity
• Absolutely zero pump noise
• Walbro pumps come with built in check valve
• System can be easily upgradable from single system to twin system
• Wiring harness included
• Totally hidden when viewing from engine bay

The “basic” single 460 system will satisfy the fuel delivery requirements of 90% of applications. This single pump system will support 550kw at the wheels on petrol (gas) and is a simple plug and play system. Twin Walbro 460 system will support 750kw at the wheels on petrol (gas).

When purchasing a twin pump system it is worth noting that the system concludes at the pump outlets of the surge tank. From this point on you will need plumb into your existing system.

When a second pump is added to the system the flow is greatly increased and the factory fuel pressure regulator is unable to control fuel pressure. At this point you will need to install an aftermarket fuel pressure regulator. For this reason all twin pump systems are configured with -6 AN fittings at the pump outlets to enable ease of plumbing into after fuel rails etc.

Single pump systems come complete with all fuel lines etc to complete the installation.

Both systems come with a pre-assembled wiring harness. Wiring installation is very simple and only requires soldering of 2 wires.

Our fuel anti-surge system is the ultimate in fuel delivery for your turbocharged Falcon.

The Process West Battery Relocation Kit is designed to free up engine bay space for large air box installations, relocating the factory battery without compromising electrical performance or reliability.

Purposeful placement.

The battery is relocated to behind the factory foglight area on the driver's side of the vehicle. This position was chosen deliberately to keep cable runs as short as possible. Long battery cables cause voltage drop, which leads to poor starting performance and reduced electrical reliability. The Process West solution maintains cable integrity and keeps the system performing as it should.

Simple, no-cut installation.

The kit is designed for a clean, straightforward install with no cutting of existing cables required. A laser cut battery tray and bracket are included alongside a high-density P7000 plastic battery terminal distribution block. The existing cables are extended rather than cut, preserving easy access for jump starting and charging when needed.

A practical, well-engineered solution for any BA/BF Falcon build requiring additional engine bay clearance.

Simple installation.

The kit is designed for a straightforward install using basic hand tools, with most installations completed in around 45 minutes. Everything needed for a hassle-free fit is included in the box.

A practical, well-engineered solution for any FG Falcon build requiring additional engine bay clearance.

Unlike anything else on the market these fuel rails are proper "machined from the solid" billet rails, not some cheap machined extrusion pretending to be billet. With accommodation for massive "-8" fittings, these fuel rails will easily cope with large capacity fuel systems using new generation large capacity fuel injectors. The twin top and single end entry/exits are designed to be configured as required. They are available to suit 11mm or 13mm diameter injectors, come supplied with two -8 plugs and mounting hardware to bolt up to either stock, or Process West Billet TGV's.

The factory intake manifold on the BA/BF Falcon is a well-known limiting factor when increasing boost and airflow. The Process West Billet Plenum Chamber is a high-performance replacement engineered to handle extreme induction pressures while delivering optimised, consistent air distribution to every cylinder.

CNC machined from solid billet.

Unlike cast or sheet-metal alternatives, this plenum is CNC machined from solid 5083-grade billet aluminium plate. This construction method produces a component with superior structural integrity, capable of maintaining its shape and seal under exceptionally high boost levels without risk of cracking or flexing. For high-output builds where standard manifolds fall short, this is the correct solution.

Blended bell-mouth runners.

Each individual runner entry features a blended bell-mouth profile. This radiused design reduces turbulence and promotes laminar airflow into the cylinder head, improving engine efficiency and power potential across the rev range. The internal chamber is sized to provide a consistent reservoir of pressurised air, ensuring rear cylinders receive a full charge even during high-RPM operation.

Plug-in wiring loom.

Each kit includes a dedicated throttle body extension wiring loom, allowing for a clean installation with no cutting or soldering of the factory harness required.

Direct fitment.

Designed specifically for the 2002 to 2007 Ford Falcon BA/BF in both turbo and naturally aspirated variants, with all mounting points and vacuum ports positioned for a professional, factory-quality fit.

The benchmark intake upgrade for the Barra engine, combining the strength of 5083 billet aluminium with flow-tested bell-mouth runners for the reliability and airflow required at elite-level horsepower.

The Process West Billet TGV Delete Kit eliminates the factory tumble generator valves, removing a significant restriction from the intake path and maximising airflow under all operating conditions.

Precision machined for performance.

The port profile is machined to suit ported cylinder heads, ensuring a smooth, unrestricted transition from plenum to head. The upper flange surface is O-ringed for a reliable, leak-free seal against both stock and aftermarket plenums.

67mm length.

The shorter of the two available lengths, the 67mm version is specifically required when fitting a Process West Billet Plenum to a GC8. For builds not requiring the shorter length, the 79mm version is also available.

Injector and fuel rail compatibility.

Injector ports are machined to accept both 11mm and 13mm diameter injectors without adaptors. Simply use the supplied Viton O-rings to suit your injector size. Fuel rail mounting points match the factory specification, making the kit compatible with stock and aftermarket fuel rails alike.
