1:7.1 Regulators

By replacing the standard fuel pressure regulator with our anodised Rising Rate model, you can enhance the performance of the standard petrol injection system. With our Rising Rate regulator the base pressure variation with the same boost vacuum value, is not "linear" but "progressive". With a 1.7:1 air/fuel enrichment rate as RPM increases a clean idle is maintained. The Malpassi / Sytec SBV regulator has been designed to provide a constant fuel pressure under any load (from idle to full throttle) and in all driving conditions.
The SBV regulator is the internally the same as the traditional Power Boost Valve in all applications. The difference lies in the anodised show finish for the discerning enthusiast who wishes to keep a smart look within the engine bay.
