This progressive fuel pressure regulator is designed for turbocharged engines where the original fuel pressure regulator is replaced with a unit that increases fuel pressure more aggressively under boost. The regulator mounts directly to the fuel rail, making it a simple upgrade for the original fuel system.
The regulator operates with a progressive 2:1 ratio, meaning fuel pressure increases by approximately 2 bar for every 1 bar of boost pressure. This provides additional fuel under boost and can be an effective solution for engines that continue to use the original fuel pump and injectors.
The integrated vacuum/boost reference allows the regulator to respond directly to manifold pressure. The design provides stable operation and fast response to changing engine loads, making it suitable for both performance and motorsport applications.
The regulator mounts directly to compatible fuel rails and requires no external return line or mounting bracket, resulting in a simple, compact, and space-saving installation.
