Atomic GFB Boost Controller

Atomic Manual Boost Controller
The Atomic is renowned as one of the most reliable and efficient manual boost controllers on the market, offering a repeatable, stable boost curve and rapid ramp-up at an excellent price-performance ratio. Unlike electronic boost controllers (EBCs), it stands out for its simplicity, robustness, and "set-it-and-forget" capability.

Main Features:

Stable and Repeatable Boost Curve: Provides a constant pressure increase without fluctuations.

100% Reliability: No maintenance required, robust and durable under all conditions of use.

Easy Installation: Takes only a few minutes to set up.

Simple Adjustment: Easy to adjust to achieve your desired boost target.

Precision Purge System: Uses a precision needle valve, more stable than ball and spring types.

Manufacturing to Standards: Manufactured in Australia to ISO 9001.

Performance and Tests:

When tested on a Subaru WRX MY02 (equipped with a turbo exhaust only), the Atomic demonstrated its performance by increasing the boost level to 0.9 bar (13.2 psi), identical to the factory controller. The dyno results showed:

Low-Rpm Power Gains: Up to 18 kW (23.4 hp) at the wheels at low RPM.

Faster Boost Build-Up: Boost is achieved approximately 1,700 rpm earlier than the factory controller, providing better acceleration and responsiveness on the road.

Available Options:

Standard Type: Fits conventional pneumatic relief valves.

VNT/VGT Type: Specially designed for vacuum-actuated variable geometry turbos, common on diesel engines.

The Atomic Manual Boost Controller is the ideal choice for those looking for simple and effective boost control, delivering superior performance without added complexity.
