on video Porsche's GENIUS New Turbo Design

 Before we get into that, let’s have a recap on how a traditional turbocharger works. 

To quote a certain fuzzy haired car journalist “exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster”.

So what is this witchcraft?

A turbocharger’s purpose is to force air into the engine, hence the term ‘forced induction’. Inside a turbo are two impellers connected by a shaft, one is known as the ‘hot side’ which takes exhaust gases from the engine in order to rotate. As they’re connected, the compressor side, also known as the cold side, spins as well, drawing in air and compressing it. 

With traditional combustion engines you need more air to make more power, the amount of power a combustion engine produces depends on how much fuel it can burn and how good it is at turning that heat into mechanical force. Now with a naturally aspirated engine the only way for the engine to get air is thru the suction created on the down stroke of each piston. But it can only suck so much air. That’s where forced induction comes in. You are forcing more air into the intake, the more air you have the more fuel you can burn and the more power you can make. 

So that’s where turbos come in. turbo’s are great, They sound awesome and they can make a small engine produce the same power a big engine would, but there has always been one negative with turbo chargers. Turbo lag, you see a turbo spins from exhaust gasses, which means when your car is low in its rev range the turbo is spinning at a very slow rate and not really adding any power. In other word you have to get into boost before the turbo starts having a positive effect on your cars performance. Now there are ways to decrease turbo lag, For instance if you add 2 small turbo’s they will spin up faster than 1 big one, other options are running a sequential turbo setup where you have 1 small turbo and 1 big one so the small one spins up first and then the big one takes over in the higher revs. Ohh and then you get the turbo’s used in Formula 1 cars. Where they have a small electric motor mounted on the shaft between the turbine and the compressor wheel. Now this system does eliminate turbo lag, but it still has its challenges, heat, you see all those electrical components have to stay alive I a crazy hot environment. So not a great system for day to day use. Onto Porsche and there new creation
