F1 » Spanish Grand Prix 2013: New hard tyre won't change much – Vettel


A forced induction engine is more efficient than an NA engine. Size being equal, a forced induction engine will be able to use more fuel for the simple reason that a much bigger mass of air will be forced into the cylinders. The fuel/air ratio will still stand at one part of fuel to every fourteen point seven parts of air. A forced induction engine will run a lower compression ratio. And finally, the pure petrol head will only see the real challenge of the ability of extracting the maximum power from an engine design when the design is NA.

The stoichiometric ratio is the perfect ideal ratio, it is a technical term used to express a perfect combustion were no left over’s are left, unburned air or fuel. The problem in real life is, there is and will never be anything mechanical which can be said to be one hundred percent perfect. The 1.6l v6 turbo will have a lot more torque at much lower engine rpm. The 1.6l v6 turbo engine running at max 15k rpm will consume less fuel than the 2.4l v8 running at max 18k rpm, even if the combustion is of the same size and efficiency there will be less combustions per minute.

F1 » F1 2013 driver salaries published – but who earns most?


Ben, Richard was quoting Berger, before one disagrees with a man the calibre of Berger one has to take into consideration his direct experience. Richard like most experienced posters on this forum can calculate with easy the difference between Berger’s experience and that of an unknown poster following the sports and most probably blinded by his support to a driver. I for one fully understand your opinion as to what the experienced Berger said.
