They say its cooler. Looks like it might have better intake towards the turbo as well.

Good stuff - may I ask where you found the diagrams? I can't say for sure but is the signature on them by Paolo Filisetti?

 

I assume the red dashed line in the Merc engine represents somesort of a shaft but what about the yellow lines? Electric cabling perhaps?

 

Another thing - I think that I read somewhere in the F14T thread that Ferraris design would be something similar (but apparently not as extreme or refined) as the Merc engine. I would be interesting to know whether the Ferrari design is closer to Renault or Merc one.

 

 

Cheers,

there was a post about this last month, cant find it though

the pic of the Merc is nothing like the diagram

The diagram has a log style ex. manifold 

The pic of the merc also seems to have both sides of the turbo behind the engine with the mguh ?

The illustration and picture do look very different. I think the M-B one looks just like that on the picture rather than the one illustrated but the advantage on turbo intake compared to Renault is huge. Probably Renault should extend they MGU-H further into the V6 with an extended shaft to improve intake. As for temperature, I do not think it would be much of a difference but that's the current news going about on this. I try and find any picture of Ferrari's arrangement will post.

Sure there might be packaging benefits and probably cooling benefits to the merc. But there are more weight on that turbo. More energy to spool it up. ofc that energy goes somewhere and you can most likely take that back but the motor spinning it up needs to be stronger and is Therefore probably heavier.

 

There is also some metal added to make sure the turboshaft is aligned and stable when it runs at 50-100k rpm.

not too sure what those yellow lines are, maybe engine structure support.

 

 That picture is from Ferrari's site. Looks like they have a system more similar to Renaults

Having look at this picture, I think your assumption is quite correct since this unit is by Magnetti Marelli.

What is much more interesting is how have the Braun, sorry Mercedes team managed to get significantly better performance than Force India/Williams/McLaren? out of the same package?

 

I would accept building the car as well as the engine would give you some advantage but not the gap we are seeing.

 

I know that there will be different fuels but I suspect that the Mercedes team has some software advantage where it can juggle (well manage)  the engine, MGU-K and MGU-H?

A real "cut and shut" job that one!

Scarbs has revealed that the turbo setup of the Ferrari is similar to the setup shown in Mercedes's promo pictures from last year, with the turbo and compressor separated by teh MGUH and mounted behind the engine. A water to air intercooler is mounted in the vee, the air passing through that and then through pipes up to the intake plenum.

 

Here is the article in Autosport+

Found this after you info. The turbo's intake looks similar to the Renaults though. Maybe where Mercedes-Benz is getting their intake is the tricky bit.
