It’s my understanding that the roll hoop is an integral part of the tub. Making that larger is a massive job, literally back to the drawing board and no way that gets done before Australia. Does anyone have any images of ‘naked’ tubs so we can see if this is true?adrianjordan wrote: ↑07 Mar 2018, 17:46If we assume that cooling is the problem, which it may or may not be at this point, but it's a distinct possibility. How difficult is it to revamp the PU cooling?
I assume it's more complex than just opting for a larger air intake above the cockpit? Could we see them adding additional air intakes on the engine cover as Renault and Ferrari amongst others have done in the past?
More direct question, can they make the changes by Australia?
Any fix, if necessary, is most likely to be less efficient when it's a late call fix. But there are not too bad ways to do it. Mercedes expanded their cooling during the '14 season with "ears" and Lotus had also a few appendixes around that area. The question is more, what and how is/are they lacking cooling. Is it just circulation at the turbo or do they need an extra oil or water cooler? During the '15 season McLaren themselves already tried a couple of solutions and they were one of the first to fully develop the roll hoop as cooling.bonjon1979 wrote: ↑07 Mar 2018, 17:53It’s my understanding that the roll hoop is an integral part of the tub.

I thought some teams have the roll hoop inside the airbox intake??bonjon1979 wrote: ↑07 Mar 2018, 17:53It’s my understanding that the roll hoop is an integral part of the tub.

Eric did say it's a heat pocket. I dont think overheating seems to be a huge issue. The issues seem to be me more of race operations side of problems than actual fundamental issues with the car. The oil leak most likely was a human error, Eric said hydraulic problem was due to part fatigue. Yesterday it was Renault's batteries that crapped out.PhillipM wrote: ↑07 Mar 2018, 20:36It probably doesn't need any bigger intakes if it's just a stagnant spot - a rework of heatshielding, a little insulating foil or perhaps just widening the cover by a couple of mm there will sort it. It's not a fundamental power unit overheating issue - they've already confirmed along with renault that they've actually got a little too much cooling capacity in the car in terms of airflow/radiators/water capacity.
No, it’s part of the monocoque structureadrianjordan wrote: ↑07 Mar 2018, 22:13I thought some teams have the roll hoop inside the airbox intake??bonjon1979 wrote: ↑07 Mar 2018, 17:53It’s my understanding that the roll hoop is an integral part of the tub.
