Some interesting differences in tyre compound choices between team mates.

Does anyone have stats to hand for Safety Car deployment at Sepang? (mtia)

Just watching fp1 now. The Renault fire is most curious.

Fuel appeared to be being pumped out the top of the car (a breather?) for ages - but surely look every car in motorsports, there is a master battery cut off that would have cut the fuel pump? It was incredibly dangerous, litres and litres of fuel pumping out.

Followed a little bit of FP2 in the F1 app, this new tarmac doesn't half heat up quick...track temps were in the low 60 degrees at one point!

Couldn't glean much from the long runs, but Vettel's pace on the Softs held up pretty well, Rosberg's run was even better though. Verstappen's run also looked pretty quick, but Ricciardo appeared to be struggling somewhat? Merc drivers fairly well matched but Hamilton having a tiny bit better pace I think.

Qualifying laps should be fun, if dry.

ETA: Looks to be a 2-stopper depending on how hot the pace is on the 1st stint and how hot the track is. Soft was lasting to about 15 laps for the top 3 cars on the pace they were doing in FP (Merc/RB/Ferrari). A Soft/Med/Hard strategy should be comfortable I think.

Honda pdate seems to have worked. 5th and 7th for Alonso, JB 10th both times

Why isn't Jenson getting the updated engine too? It is unlikely he will score any points without it so he might as well take a penalty (if he would be due one) and start using the new engine as soon as he can. Apparently he wont take the new engine at the Japanese grand Prix because Honda don't want a grid penalty at their home Grand Prix so why not take it now?

At the moment they're not even planning on using it in the race, just for practice, so no big deal.

Its got that lovely very dark, almost black look you only get with good new tarmac. Surely contributing to the high temperatures.

Now they have decided to park Jenson on the reserve bench they don't want him to look too good do they?

yes The technical term for it is albedo, I believe. The darker the tarmac, the more heat it retains. smile

I wondered if it was being pumped out. What I couldn't figure out was if you did have some sort of breather for the fuel system, why put it at the top of the car, near the driver ? surely you'd put it in the sidepod ? if that breather is not fuel the fuel system, then whatever broke to let the fuel leak looks to be pretty significant. When you think that the fuel is supplied to the engine at a much lower height than that and much further back, its just a really weird place to see fuel.

The others were:
The mechanic to Kevin's left holds out his hand to help Kevin exit the car - nice chap, but nowadays the drivers are told not to be in contact with the ground and the car at the same time if the ERS system isn't safe (hence they stand on the car and jump off). Given the thing was on fire who knows where the ERS system was, could have been a bit shocking...

2nd thought: Charlie has said that as fires are so rare now it doesn't matter if halo means that it takes longer to exit the car. So far this year we've had two fires and one big rollover and no incidents that halo would have made a blind bit of difference to.

Just more proof its a political thing than a safety thing.

Ah but they didn't bench him remember, he swears blind it was all his decision...


Aha, so Ruth from Haas has turned up at Sauber..

Ted Kravitz got a right bee in his bonnet about people in shorts and shirts standing so close to a car that kept bursting into flames, and I have to say that I totally agree with him. It seemed incredibly blasé and lacking in basic health & safety.

In other race series like DTM, if you're in the pits when the cars are running, even in practise, you must be in fireproof overalls.

Given the constant strive for safety in F1, and also the almost fetishistic concern with rules and regulations, I'm surprised that we don't have a similar rule.

The car had already been jacked up and placed on the dollies so it would have been safe. There are lights where the camera mounts that indicate if the system is charged or not.

Agreed, but the frigging thing was on fire, at that point who knows if it really is safe or not...

Haven't they said that JB's engines are not near enough to their expiry, but Fred's are, so he'll take the plunge.

One of the Renault guys (interviewed in FP2) said "the blocked breather had caused the fuel tank to become pressurised" so a cut off switch wouldn't help. I can't work out how that could happen, surely a blocked breather would cause a drop in pressure in the tank not an increase.

Assuming a breather does what it says on the tin, how on earth would blocking it cause a drop in pressure?

Blocked breathers on road cars invairiably leads to a vacume in the tank as you take more out than you put back in (engine uses it to run), that is if an F1 car uses a fuel return system, i assume they do ?
The only thing i can think it was was heat causing the fuel to boil off into a gas and expand whilst the engine was off, leaving no exit for the excess pressure ? at least not untill something gave out and let it out ? hense why pumping the remaining fuel out stopped the flow, it was a strange one that's for sure.
Tin foil hat on,, it was staged cos the teams don't want the halo and so have been reproducing senarios where the halo would be a danger to provide an easy "out" biggrin

In FP2 they said that (somehow) the problem was forcing air in to the tank, thus displacing the fuel and forcing it through the breather...

Still can't work it out to be honest..

Fuel pump sucks fuel out but air can't get in (to the tank) to replace the lost volume.

But why wpi;d a drop in pressure blow fuel out ?

almost looked as if fuel had got into a length of the breather system, then blow out as the tank contents warmed.
