The Precision Raceworks Stand-Alone Auxiliary Fuel System is the highest performing and most stable low-pressure fuel system on the market! Forget about how things have been done and embrace the benefits of dedicated fueling for your port injection!
Since direct injection came out, enthusiasts have been adding port injection. With this came the need to upgrade the low-pressure fuel system to keep up. Historically, this was done by increasing the output of the main fuel system. Unfortunately, the main fuel pump is controlled using PWM by a factory-programmed controller designed to reduce output when target fuel pressure (typically 5 bar) is exceeded, creating a constant battle when pumps are added or upgraded. This limits upgraded fuel pumps from performing to their full potential.
Additionally, the high-pressure pump control system dumps fuel back into the low-pressure system at high pressure, low volume, resulting in oscillations of the low-pressure fuel system. Because of this, the DI system in the car is required to constantly make corrections to keep the target AFR in check.
With this stand-alone low-pressure fuel system dedicated to your port fueling, that is a thing of the past! Get rock-solid fuel pressures at any pressure, run fuel pressures which are 1:1 scalable to boost pressure, flow more fuel with dedicated lines, run smaller injectors and still get more fuel than you did with large injectors (allowing for higher resolution), and put less demand on the car’s DI system to correct for fluctuations in pressure. Even your tuner will be grateful as the system makes tuning of port fueling even easier and more accurate. The list of benefits goes on and on!
