The cold side of the turbo takes fresh air in compresses it, cools it, and force-feeds it back to the engine via the intake manifold. An impeller is designed in such a way that its blades ‘grab’ onto air. Turbos have two impellers one spins with the exhaust gases (the ‘hot side’) and causes another impeller connected to the same shaft to spin as well. Turbos use the exhaust flow pressure to spin a centrifugal impeller, or a turbine wheel, in a vacuum housing, to create high-pressure air. Turbos are directly connected to the exhaust manifold.

The turbo is responsible for forced induction hint: Superchargers also do this, interested to know how the two compare? Make sure you check out our turbocharger vs supercharger guide. A normal turbo would look something like this if you’re seeing it for the first time:Ĭonnected to the engine are the vehicle’s intake and exhaust manifolds, which are each responsible for getting air into the engine for combustion to happen, and getting exhaust gases out. Turbos sit in the heart of petrolheads and are a must-have for car enthusiasts of all sorts. But we’re here to tell you about turbos and turbocharging and what makes those sweet whistle noises we all love here at Drifted.

If you’ve done your homework on engines you probably know all about them. But sometimes, the sounds from your turbo may be a sign of issues, and we’re here to explain why. We love turbos, and we’re crazy about the sounds they make.
