Turbo engines where used in the 80's. But stopped as drivers had bad necks from the G force of the energy inflicted on there helmets. The Hans Device will fix the problem. So what is a a Turbo Engine. Well anyone who has has played the video games knows there is usually a turbo button that makes you go super fast. Basically the air is sucked in from outside. (Probably in the side pod or the air-box inlet above the drivers helmet, or a separate inlet hole) It goes into a curled meatal pipe that has a fan and a small valve. This compresses the air so it makes a lot of energy (like a pneumatic air gun, the compressed air powers the gun) The compressed air goes into the engine giving super cooling so the car can run under extreme stress levels beyond what could be achieved form a normally aspirated engine like they used in 2013. The difference is the sound. The air being sucked will sound like a vacuum cleaner. And the Turbos only run 6 cylinders in a traditional V, 3 on each side. Or they can do like BMW did at Brabham and run a straight 6 where all the cylinders are straight up and down. This would be hard to do as there is more stress on the cam shaft. We could even see teams do like in the Mini Cooper S and run a straight 6 horizontally so it is mounted sideways.
