What does a Wastegate do?
If you don’t know how a turbocharger works, first read How does a Turbocharger work at the beginning of this section. It’ll explain some ideas referred to here. As you know, when enough exhaust gas flows past the turbine wheel of the turbocharger, boost is created. The faster it spins, the more boost you get… the more boost you get the more air the engine consumes… and the more air it consumes, the more exhaust gasses flow… and the more exhaust gasses flow, the faster the turbine wheel spins… and the faster the turbine wheel spins, the more boost you get… the more boost you get… well, you get the picture. Potentially, the engine will just put itself into an unending loop of increased power. But at some point, the turbocharger or motor will eventually blow up (unlimited power just by having a turbocharger is just too good to be true!). This is why the wastegate is essential in any turbocharged engine. How it works is with a vacuum line that connects from the compressor outle
