Genuine Malpassi Fuel Pressure Regulators

  • For applications on aspirated or turbocharged engines
  • 1:1 air/fuel rate
  • Compatible with alcoholed fuel (E85)
  • 2 x INLET/OUTLET port 1/8" NPT
  • 1 x RETURN port 1/8" NPT
  • 1 x  vacuum a/o boost connector, 5 mm tail, on 6x1 mm threaded port

Unlike some cheaper regulators these are properly referenced to the manifold pressure. As the manifold pressure changes (vacuum on cruise, higher pressure under boost) the injectors are 'seeing' different pressures, but the ECU fuel maps are configured for a steady state. The vacuum take off means our fuel pressure regulators constantly adjust the fuel pressure to suit the ambient pressure inside the manifold- keeping your chosen fuel pressure secure and accurate.

For those trying to get the most out of their stock injectors but using aftermarket engine management these adjustable fuel pressure regulators mean you can increase the base pressure behind the injectors. This has the same effect as fitting slightly bigger injectors as more fuel is dispensed for each opening of the injector.

Specifications

  • Max Flow 5 Ltrs/Min

  • Adjustable 1.5 Bar (22 Psi) - 6 Bar (90 Psi)

  • Tested upto 10 Bar

  • Rate is 1:1 for Turbocharged applications  (NOT rising rate)

  • Referenced to manifold pressure

  • Please note- No fitting instructions are provided- This FPR should be set up professionally with the aid of a rolling road and/or wide band lambda.



    CONFIRMED: McLaren P13 will arrive in 2015 to take on Porsche 911 & Audi R8

    Sat, 16 Nov 2013

    McLaren has confirmed the McLaren P13 will arrive in 2015. The original plan for McLaren’s new range of supercars was that the 458-bashing 12C would arrive first (which it did) followed by a more affordable mid-engined car – think nearer £100k than £200k – to mop up sales from the Porsche 911 and Audi R8. But McLaren decided they should get the P1 out before the P13 so they could give their dealer network a nice halo model, and go head-to-head with LaFerrari and the Porsche 918 Spyder.
