Go Fast Bits Atomic Single Stage Boost Controller

The Atomic boost controller, a standout in Go Fast Bits' product range, is renowned for its unwavering reliability and stellar performance. This exceptional manual boost controller has garnered a strong reputation for its ability to deliver a consistent and stable boost curve, lightning-quick boost rise, and exceptional value.

Go Fast Bits conducted rigorous testing on the Atomic Boost Controller using an MY02 Subaru WRX, which had been minimally modified with just a turbo-back exhaust system. The company aimed to provide an unbiased evaluation by performing a direct comparison. Initially, they conducted a baseline power test using the factory boost control system while simultaneously measuring boost levels. Subsequently, the Atomic Boost Controller was installed and configured to achieve the same peak boost level of 0.9 bar (13.2 psi). This ensured a precise comparison of spool-up times before and after installation.

The accompanying dyno chart clearly illustrates the Atomic boost curve depicted in vivid green and the factory curve in solid blue. Both tests were performed in 4th gear, and towards the end of the chart, where the two curves intersect, it's evident that the Atomic was indeed adjusted to reach the same peak level. The most remarkable aspect of the comparison is the substantial increase in power, particularly in the lower rev range, with gains reaching as high as 18 kW (23.4 hp) AT THE WHEELS!

This notable power increase underscores the Atomic's ability to achieve significantly earlier boost rise compared to the factory controller. On the road, this translates to markedly improved acceleration, starting as early as 1700 RPM lower in the rev range. Importantly, these improvements are achieved without exceeding the factory peak boost level, making it a cost-effective modification that offers outstanding value.

It's important to emphasize that this upgrade is particularly effective on the MY01-02 (MY02-03 in the US, GDA chassis) model due to the factory boost mapping's conservative nature. The factory settings are deliberately designed to maintain a flat torque curve and linear power delivery, which, unfortunately, compromises the overall turbocharged driving experience. While it's possible to increase boost levels beyond the factory settings for additional power gains, Go Fast Bits' experiment focused on highlighting the enhanced spool-up potential for this specific WRX model.

In conclusion, for those looking to infuse their GDA WRX with a new level of energy and performance, the Atomic or Reactor boost controller from Go Fast Bits offers an outstanding solution. These controllers represent a highly impactful and budget-friendly modification that unlocks the full potential of the vehicle while delivering excellent value.
