Go Fast Bits

Got a turbocharged car and want control over boost and quicker response between shifts? Go Fast Bits, often called GFB, makes blow-off and diverter valves, boost controllers and other turbo parts for tuners and enthusiasts. Here you’ll find valves that install directly in place of the originals, as well as solutions for cars running more boost than stock.

Australian turbo parts with a focus on valves

Go Fast Bits is an Australian brand specialising in parts for turbocharged engines. The brand is especially known for its blow-off and diverter valves, which release pressure when you lift off the throttle, so the turbo is not stressed unnecessarily and boost returns faster. Many of the valves are designed as direct replacements for specific car models, making installation simple, and several models are adjustable to suit both stock boost and higher boost after tuning.

Go Fast Bits’ key products

Blow-off valves vent air to atmosphere and give the characteristic sound, while diverter valves send the air back into the intake, which often suits cars with a mass airflow sensor best. Go Fast Bits also offers hybrid valves where you can choose between the two. On top of that come electronic and manual boost controllers that manage boost pressure, plus smaller turbo and vacuum parts such as hoses and fittings. See each product for car and engine fitment.

Frequently asked questions

What is the difference between a blow-off and a diverter valve?

A blow-off valve vents the pressure to atmosphere, while a diverter valve sends it back into the intake before the turbo. On cars with a mass airflow sensor, a diverter or hybrid valve is often the best choice, because the engine management then gets the air it has measured.

Do I need a new valve if I raise boost?

Often, yes. Original valves can start to leak at higher boost, so the turbo loses power. A stronger, adjustable valve stays sealed at the boost you run and still opens when you lift off the throttle.
