Go Fast Bits Manual Boost Controllers may lack features of an EBC, but they get the job done!
Boasting a repeatable and stable boost curve, quick rise rate, and unbeatable value, GFB's Atomic has earned a reputation as being one of the most reliable and effective manual boost controllers on the market.; It is important to note that the Atomic does NOT use a "ball-and-spring" system like others on the market, for very good reason. The ball-and-spring system is an attempt to increase the boost rise rate by preventing pressure from reaching the wastegate during spool up. However, in practice this method usually creates boost spiking and a less stable and repeatable boost curve. Instead, the Atomic uses a precision orifice and needle valve system to accurately bleed pressure from the wastegate line to increase boost. With no moving parts, this system is ultimately more reliable and stable. For use with any type of petrol/gasoline or diesel turbocharger system using a traditional pneumatic wastegate (internal or external).; When you need simple, reliable, set-and-forget boost control, a Manual Boost Controller is hard to beat. Installation is as simple as connecting a couple of hoses, and setup is as easy as turning the adjustment until you hit your target. Once that's done, you can forget about it and drive your car. Being a rugged, mechanical device, it will never vary or fail, no matter how much abuse you can throw at it.
