From the beginning of 2016, the FIA will make changes to the current Formula One turbocharger wastegate, in the bid to create a ‘louder’ racing car.
From the start of next season all cars must have a separate exhaust wastegate tailpipe through which all and only wastegate exhaust gases pass out of. This means we will see one turbo wastegate, and one wastegate for more engine noise.
A wastegate works by valves opening and closing. A wastegate is normally closed and held shut by a spring inside the actuator canister. When the correct pressure builds, gas levels are then exceeded within it. The actuator progressively opens the wastegate, allowing exhaust flow to bypass the turbine, which can then be used by regulating manifold boost pressures.
This will enter the sport after final analysis by the FIA. In this section of the car it’s all about pressure and what you do with them, but get it right I can assure you the 2016 cars will have a noticeable change in engine noise.
