Adjustment and operation
The spring pressure values listed for each colour marking represent the minimum regulated pressure. The actuator is supplied as standard with a spring featuring a yellow colour marking.
The Forge actuator enables more precise adjustment and control of boost pressure, which can improve response and control. The standard spring is suitable for the factory boost pressure or slightly higher values. A stronger spring can be used for vehicles with higher boost pressure requirements.
Diaphragm-sealed internal components are the standard version for this product, while piston-sealed internal components are also available. The piston version offers comparable operation and requires less maintenance thanks to its more durable internal components.
The product is designed to increase the boost pressure of the turbocharger system. Compatibility with all versions cannot be guaranteed, nor can an increase in boost pressure beyond the limitations set for the specific vehicle by the factory-fitted or aftermarket engine management system be guaranteed.
For vehicles with a modern ECU/solenoid system, the mechanical spring pressure is not necessarily equal to the target boost pressure. When choosing a spring for a specific model and planned level of modification, follow the advice of a suitably qualified tuner.
All actuator rods are made from 303-grade stainless steel.
For the T2 spring kit (FMAS049), select the Diaphragm Type 2, 049 option.
Kit includes
- 1 × FMACFRS2 actuator
- 1 × Forge sticker
