APS EXTREME PERFORMANCE FUEL SYSTEM
APS Extreme Performance Fuel System
For ultra high horsepower (600 - 1,000 flywheel horsepower) applications, APS has developed a thoroughly engineered Extreme Performance fuel system that is not only very comprehensive, but also highly cost effective and relatively easy to install.
Designed to operate with twin turbocharger or large single turbocharger forced induction systems, the heart of the APS Extreme Performance Full Return fuel system is the replacement drop-in surge tank/fuel pump assembly that incorporates twin high volume fuel pumps, return circuit and provision for the stock fuel sender assembly. Precision construction in stainless steel ensures that the APS drop-in pump assembly delivers bullet-proof reliability and a fume tight seal for total peace of mind.
Each of the twin high volume fuel pumps situated inside the APS drop-in surge tank deliver a huge volume of fuel to their individual Teflon lined stainless steel braided hoses. By mating each fuel pump with its own fuel line to the engine bay, the maximum flow rate possible is achieved in order to consistently deliver very high fuel flow for high horsepower.
With twin fuel supply lines to the engine bay, each fuel line feeds its own billet aluminum fuel rail, thus eliminating any fuel flow restriction that would have been caused if a single shared fuel supply line was run.
In order to deliver rock steady fuel pressure, two 4 Bar fuel pressure regulators are specified - one for each fuel rail. In addition, the fuel pressure regulators are boost referenced - which means that the fuel pressure differential across each injector face remains constant regardless of the operational boost pressure level. In other words, consistent fuel pressure is achieved whether decelerating (vacuum), cruise conditions (low boost pressure) right through to very high boost pressure levels commonly experienced at extreme power levels.
Boost pressure referenced fuel pressure also ensures that the six 880 cc fuel injectors included in the APS Extreme Performance Full Return fuel system operate to their full potential to deliver and sustain 1,000 horsepower of fuel to the engine.
In addition, the two fuel rail/fuel pressure regulator assemblies incorporate a fuel pressure balance line to deliver perfectly balanced cylinder bank to cylinder bank fuel system performance.
Being a full return fuel system, the APS Extreme Performance fuel system is engineered to return fuel to the APS drop-in surge tank via the stock fuel supply line (the stock fuel supply line now operates as the return fuel line). This takes advantage of the robust single fuel line configuration that has more than sufficient capacity under its new role as a fuel return line.
In a nutshell, the APS Extreme Performance Full Return fuel system is two complete fuel systems. Twin perfectly balanced 500 horsepower fuel systems - one system for the left cylinder bank and a matching system for the right cylinder bank - each with its own fuel pump, fuel rail, fuel pressure regulator and associated hardware - and with a common return line back to the fuel tank.
In addition, highly robust Teflon lined stainless steel braided fuel lines that are spiral wrapped and a replacement fuel injector loom are included with the APS Extreme Performance fuel system for straight forward installation and years of hassle-free high performance motoring.
The APS Extreme Performance Full Return fuel system delivers a huge volume of fuel at a rock steady fuel pressure that is balanced and boost referenced for the ultimate in fuel system performance on extreme horsepower VQ35 engines.
The APS Extreme Performance fuel system is supplied complete with every nut, bolt, clamp and bracket required for easy installation.
750cc fuel injector rating is based the 4 bar pressure that this system operates at, this injector is flows 650cc at a standard test pressure of 3 bar. While this is enough for most applications those needing a true all out fuel delivery solution are recommended to upgrade to our optional Siemens 975cc @ 4 bar (850cc @ 3 bar) injectors.
For reference :
3 BAR = 43.5 PSI
4 BAR = 58.1 PSI
