FS NIB (2) Bosch 4.0 bar Fuel pressure regulators
New in box, bought for a project that I decided not to do, never installed.
I understand they are popular upgrades for the VW/Audi/Porsche crowd, so I'm posting them here. Built a high flow/pressure fuel system for my car and went a different route. 2 available 4.0 Bar Bosch Part Number: 0 280 160 575 Again, these are brand new in original boxes/packing. Was thinking 70 Shipped , OBO. Please let me know. Local pickup can save shipping, local to: SE MI. 4.0 Bar pressure regulators will increase base fuel pressure over a 3.5 bar regulator by aprox 7.35 PSI and increase injector flow by aprox 7%, provided your pump can handle it. If you are running at, around or higher than a 95% duty cycle with a 3.5/3.0 bar regulator, this will give you more headroom for power with out having to upgrade your pump/injectors and put you in a more optimal duty cycle range. Higher pressure means better fuel atomization and lower duty cycles. I planed on running this with a 255 LPH Walbro, on a force induction engine running ~15 PSI of boost which would give me a final fuel pressure of ~74 psi under Wide Open Throttle. You can find out your fuel increase with : http://www.csgnetwork.com/fiflowcalc.html Any fueling changes may require ECU tuning, please keep that in mind. Pictures soon. |
