Honda Power Unit Hardware & Software

[Dimi]

Before the announcement i would bet that it was a gearbox failure. Kerb hit- couldnt upshift- engine working- smoke from the bottom of the car, far below exaust pipe.

Maybe there was an underlying problem and the bottoming was the final hit.

Hitting the bump may have been the final straw in the life of this unit as Gasly was also through the gravel trap in Q1 which would've result in more unnatural loads on the chassis/PU. Difficult to assume anything, it is what it is and they'll move on.

[Sieper]

this is a one race old PU, under no circumstance should it destroy itself when bottoming out. This is a major (issue (or lets hope not) but it needs to be resolved.

Gasly says he had upshifting problem before the PU. There are problems more than one. But main problem of Honda, from reliability point MGU-H weakness from outside affects.
I readen here mercedes worked very much to have reliability with their MGU-H. I don't know if they see Honda's issues or it is different.
İf Toro Rosso had good result with other car, this dnf wouldn't be so important any of us.
Hartley says he also live a puncter then he drove alone but his pace also looks slove. I hope these all will be different at next races.

[Thunder18]

Hartley's puncture damaged some of the floor and a result he was losing downforce so could not live the pace of the cars in front of him. It was also a track new to him and Gasly too. I will imagine they will both fair better at regular track circuits.

I posted earlier re Gasley and the turbo blow up on the bump, where there were two trails of smoke possibly indicating waste gate involvement, sometimes when turbos get too interested in themselves the debris can lodge under the valve leaving it open, but still the majority should still come out the tail pipe?? there is something there worth analysing, any ideas?

Of Course this is something that don't happen in Barcelona, even more with the new Asphalt, but such Things happen thousand times in a Season. A engine HAS to endure that.

Albert park is a car killer, a mistake can have disatrous consequences, ask Bottas, or Vettel in 2010, or Riccardo last year.

It's not a big deal, the car will improve, let's see what happens after the flyaway races.

[godlameroso]

Just because the valve seats have to be circular doesn't mean the intake ports, have to be. Anyone that knows anything about ports knows while they may not improve flow as much as the valve seat itself, they do wonders in determining how air flows into the cylinder. Tumble, swirl, etc, but Honda is already very good at this, as is Toyota. This is why I'm not worried about the performance of the power unit, once they crack the code on the flame injection it's only a matter of time before they can synthesize it into their existing knowledge.

You can blame the track all you want, the very short duration accelerations produced by bumps/kerb strikes rarely fail PU components. Bottas registered 27g and they re-used the PU.

And Sirotkin's bulletproof engine died on the first lap, and Ericcsson's Ferrari. Plus you can't compare a TR chassis with a Mercedes one.

Huh ? Sirotkin failed the brakes due to a plastic bag stuck in the duct ? Ericsson had a wonky wheel nut ?
No one designs a chassis to take 27g. There are no special measures to protect the PU when you drive into a wall.

What is your point ?

Point is it's not the bump that caused it, bump was just the final straw. Not worried about it, sure it's a shame they're one PU down, but not a big deal in the grand scheme of things.

[j.yank]

I see that the timing in the 3rd sector in Australia is really bad for Toro Rosso, comparing with the first two sectors were they are almost competitive to the leading teams in the middle pack, and their speed trap is also very bad comparing with tests when they were among top teams. Could this be indication for poor harvesting, particularly on this track?

Well, one PU down out of 3 with 20 races to go is still pretty big in the grand scheme of things.
And they are not blazing quick either.

It looks like the same sort of MGUH issues they were plagued with last season. If this really is a design issue, the replacement Turbo/MGUH is bound to be the same spec as the one that failed.

I suppose that's what the mid season upgrade centers around rectifying. It really isn't a big deal, it's obvious they're backmarkers, so penalties do nothing to them in the grand scheme of things. If everything is perfect they qualify near the back, if everything is a disaster they qualify at the back. Even if they take new engines and penalties every race it has no impact on their qualifying performance, but it can certainly move them up the grid during the race.
