did i read on twitter that martin brundle believes there will only be 10500 revs max next season is that true or? personally im gan miss the sound of the v8's next season these tyres are not even made of a "rubber" substance cant think what its called but remember them talking bout it a few races back in fp3!

pady. I think that 12000 was proposed but then amended to 15000

re the tyres I noticed in practice for cota, there was at least one car using unmarked tyres. cant remember which one it was but maybe the marussia

I don't think that is true. it is the cylinder size that governs the noise. the v8s have 300cc per cylinder and the v6 1600s will have just over 260 cc, so sound will be higher pitched

A couple of weeks back I said on here and many were surprised and doubted it and that including Taipan, that the new engines will be using 10500rpm max during the race, those were my technical calculations when taking into consideration the mandated fuel flow permitted and the total fuel load for a race distance, I admit that technically this is not easy to understand, but as I have tried to explain on here many a time, power output of an IC engine is directly related/dependent on the amount of fuel burned, the simplest way to explain it is as follows, the strongest combustion using regular pump fuel can be had burning fuel at a fuel/air ratio of 14.7 parts of air to 1 part of fuel, this regardless if the engine is neutrally aspirated or forced induction, the more air that can be crammed into a cylinder the more fuel that needs to be burned.

Many people I talk to believe/are under the (wrong) impression that the rotary switch on the steering wheel which says fuel rich/lean as used by a driver when ordered to save fuel is used to either lean or enrich the fuel to air ratio, what this switch does is degrees or increase the max engine RPM, the lower the RPM the less fuel used, the higher the RPM the more fuel used, the fuel to air ratio stays the same.

not to worry. merc have already had running on next years tyres with a current car, and red bull have run them on a 2 year old car as have ferrari. ALL teams are provided with the opportunity, so nobody will be able to complain

I don't know if next year's tyres were used or not and by whom, but I was reading that RBR while supposedly running for filming purposes at Los Arco Navarra on tyres supplied for the purpose they were running/cam testing a 2014 mandatory low nose.
