A new model of our most popular reducer, the STAG R02 DPI, joins the STAG R02 reducer family. Featuring advanced dual-membrane technology, this compact reducer provides precise pressure control for optimal engine performance.
Designed for cars with direct fuel injection and turbocharging, the STAG R02 DPI is a master at adapting to changing engine conditions.
Its small size makes it easy to install even in small spaces under the hood of the car.
Why R02 DPI?
The R02 DPI's two diaphragms operate synchronously to provide smooth and efficient pressure control. This is the key to maximizing your vehicle's power and performance. Calm city driving or dynamic acceleration on the highway - the R02 DPI responds intelligently to any engine load.
A versatile companion for any driver
R02 DPI is a versatile partner for any STAG controller. It works perfectly with both direct injection systems and turbocharged engines. Designed to handle up to 220 horsepower, it is ready to perform under the most demanding conditions.
What sets the R02 DPI apart?
- Dual valve control: two diaphragms for double precision.
- Compact power: smaller size, consistently powerful performance.
- Versatility: ideal for direct-injection and turbocharged engines.
In naturally aspirated engines, R02 DPI maintains stability without increasing pressure. For these engines, we recommend other STAG reducer models that are tailored to their needs.
How it works.
The vacuum controls the R02 DPI, increasing the gas pressure at the output of the regulator. This means that on turbocharged engines, where the vacuum can range from -0.3 to 3 bar, the R02 DPI intelligently adjusts the injection pressure from 1 to 1.7 bar, depending on the engine's needs.
The benefits?
It's simple - the R02 DPI allows precise control of the injectors, increasing pressure without affecting their opening and closing times. This means higher performance without the risk of looping gas injectors.
