Porsche already had one fitted on one spec of their front windshield in 2014, there's just two now and are fitted symmetrically across the car's centerline. Don't know if they're driver or hybrid system cooling, though.

Porsche are also running a split exhaust (like the EBD Audi R18) with periscope outlets like the Toyota TS030/TS040.

Good question, but would say the MGU-H will be the same layout. I have read somewhere that a twin turbo layout did not work with a MGU-H system. So I think they have switched the exhaust layout to a 1 in 2 pipe system after the turbo. Maybe to have the same flow conditions on each side of the fin.

Note that these ERS-H turbines would not count as MGUs since they are not used to release any energy. Just two separate electrical machines to harvest energy and being associated to one and same car sub-assembly, i.e. the engine exhaust, therefore one and a same Energy Recovery System Assembly (ERSA) as per Article 1.20. Still two ERSAs as such (ERSA-K on the front drive train + ERSA-H on the engine exhaust). This obviously assuming that we are indeed talking about a bi-turbo configuration. These might as well be just split exhausts as mentioned by chernaudi. |

Good. It was very strange to see a Vee engine with a single exhaust pipe, even though it's not enforced by the rules.

Sorry my mistake, Have forgotten that Porsche did not use a F1 ERS-H system which has a MGU-H. Comes a bit as I try to image how the planned ARX-04a for HPD may have looked like. And the V6 engine for this car was planned around a battery optioned MGU-K and a MGU-H together with the turbo inside the V. Have had the thoughts in my mind if a 1 in 2 pipe would make any sense to get the same airflow on each side of the fin. So mixed these two engine concepts which are not the same. |

What I have managed to find out is that the planned HPD HR22T engine for the LMP1 category was a 2,2l V6 engine based on the Indycar engine. In contrast to the CAD renders which have appeared on the net , the exhaust pipes and the turbo were arranged inside the V. The engine was fitted with two ERS systems developed by Magnetti Marelli. A ERS-K system with batteries and a F1 style ERS-H system. As I haven't heard anymore on this project and the LMP1 ARX-04 is stopped as Honda did not want two different hybrid outfits in racing ( F1 with McLaren and LMP with HPD and Wirth) I don't know if the engine was fully developed. But I will try to find it out. |

It would be possible to power an MGU-H with two turbo chargers.
If the MGU-H is placed transversly with a shaft coming out both ends. On each end of this shaft is a turbo charger, one for each bank of cylinders. The biggest issue might be bearing alignment but there are ways to overcome this. |

Really like the new lines on the 2015 919 and can't wait to find out what livery Porsche will roll out to spoil it.
