Christian Horner says reliability will be the key thing for teams to come to terms with when the 2014 F1 season starts later this month with the first tests of the year

I don't see any of the three pushing their engines to the fail point limit, in fact if you read what I said elsewhere about as to what engine rpm they will red line their units at as against what the rules allows you will agree that they will not as reliability will for sure be a major factor this year.
As to turbo turbines exploding I was not joking, it was what I read.

Rob, that's exactly what I had in mind, engine mileage because of the number of units allowed during a season which is going to be critical this year. As you know the rules allows a maximum of 15k rpm but at the same time restricts fuel flow rate to a point where fuel flow rate will start to diminish at 10500rpm, when an engine reaches the point where it cannot burn any more fuel because of the mandated fuel flow restrictions there is no point in pursuing more engine rpm as there is not going to be any more power produced, that is apart from the normal overshoot where gear changes takes place. What is called max power speed of an engine is tailored-in by design of the intake system (the point when max speed of the incoming charge is reached it's called the lovel factor), that is the point of max output, above that speed no engine can produce more power because the charge will start to diminish, but in the turbo engine case it's the fuel flow that will start to diminish.

Sunny, so you expect the engines to only be running at 60-70% of their capacity due to the fuel stipulation in the rules?

Wouldn't manufacturers then just move the bar and design the engine to that limit ... maybe by taking off weight?

I agree with Rob, in that surely every manufacturer is is testing the various components of these power units to the point where they expire ... so news of items exploding during bench testing should be an almost common & boring at this point?

I don't see any real reliability problems developing, the engine manufacturers have had plenty of time to iron out any problems
they might have had and in addition the engines have to achieve a
certain leval of reliability as there will be less engines available to
each team I believe. I simpy don't see engines blowing up or developing
major faults although I except that there will be some tinkering going on
to get the best out of them.

Sunny, speaking of the problems which you and Horner mentioned about the turbo engines, do you believe that any driver will be able to complete the season with 5 units? Personally I don't think so, and they will take grid penalties so we can watch the guys from the top teams starting from well behind the first rows and RACING from there, always if the Pirellis will allow them to race.

Fullofit, read carefully, the max power/speed of an engine is tailored-in by design, in a F1 engine design when there was no rpm and fuel restriction the aim was always to fight reliability and go ever higher on rpm and therefore obtain more power output, when rpm restriction set in whatever the rpm number was the max power/speed would be tailored-in at 500rpm below the red-line on a NA engine, according to Renault there turbo engine max rpm red-line will be set at 12000rpm which means 1500rpm above their max power-speed of 10500rpm, the 10500rpm number is the point where max fuel flow will start to diminish and so will the power output, using the engine above the max power-speed apart from the benefit of changing gear there is nothing to be gained. Now-a-days parts are tested to destruction point before they are even manufactured (computer) So exploding things means the sums weren't good. The minimum weight of the engines are set by the rules.
