Honda Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

They're worried that Ferrari has the best power unit so far this year?

So, I've compared that with this:
https://www.youtube.com/watch?v=yx6BbFTNyy0

Starting from Turn 7.

Max sustained speed in Turn 7: Hamilton 274; Alonso 268
Apex of 8: Hamilton 189; Alonso 174
Apex of 9: Hamilton 114; Alonso 117
Apex of 10: Hamilton 207; Alonso 206
Short Straight Max KPH: Hamilton 289; Alonso 278
Minimum speed through 11: Hamilton 93; Alonso 81
Speed at white line of 12: Hamilton 101; Alonso 114
Speed at Rolex Board: Hamilton 220; Alonso 216
End of curb exit of 13 onto back straight: Hamilton 285; Alonso 280
DRS line: Hamilton 307; Alonso 299
Max speed: Hamilton 329; Alonso 318
Minimum speed through 14: Hamilton 68; Alonso 58
Max speed before 16: Hamilton 262; Alonso 254
Apex of 16: Hamilton 167; Alonso 167
White line after exit of 16: Hamilton 233; Alonso 236
Finish line: Hamilton 286; Alonso 278

Alonso brakes more heavily and takes a tighter line than Hamilton in slow corners preceding a long acceleration period - e.g. Turns 11 and 14. I guess the logic being he is looking for the best exit speed to minimise the deficit down the straight that follows. It works well through 12, as he enters the long (really long) straight at roughly the same speed (220 vs. 216). From that point onward the McLaren-Honda bleeds about 10KPH throughout the length of the straight.

I'm no expert, but I don't see much evidence of a compromised aero set-up. Alonso's apex speeds are good - Turn 7 being a prime example of this. Hamilton was mighty through 8. Most of the other corners are very comparable. If Honda find another 50bhp, I'm sure Alonso will know what to do with it!

They might even have a setup for rain.. but at first glance it could be said that PU ferrari 2016 has an advantage (for the moment)

Dont think so tbh as it doesnt concern Zak. They are so far behind that they wouldnt even care. Although after vettels win, Ferrari did send Luigi Fraboni on podium, and he is head of track ops as far as engine goes. It reminds me of first Merc win in 2014 and Andy on podium.

Even more if the piston itself forms part of the pre-chamber. Then the flame jets can be incorporated into the piston crown.
That would give variations in the quality of the jet that you get. That would be hell to tune, but at least you get the benefit of having two modes: normal injection mode and jet nozzle mode. It is a good idea none-theless. It was suggested before on here, a few-sketches too, but no-one really explored it.

I was at the qualifying session at china GP. Some observations.
I sat at the center of the starting grid, row 7. If i see directly straight, it will be the Kimi and Bottas's spots tomorrow in race.

When alonso's car flew by, the upshift sound was almost like gears grinding while VAN's car won't have this sound(sounds normal)

Why is this? I thought the new gearbox is the same design as the old one?

Have you compenseted Alonso's speedometer being hugely out of synch with the picture? (Just look at how the DRS button glows in green about 20 or more meters before he actually cross the DRS line)

Maybe try recording audio tmrw from your seat, if the sound repeats.

In the app is always anticipated to the image of the tv, also does not match the acceleration and braking with the image. Maybe they are superimposing the image of the app in the image of the tv, that is why it leaves with a delay of time the image of the tv with the data of the instrument panel that they show us.
The app works about 7s before the image, it does not seem as much time lapse but it is not synchronized.
I do not say that Fulcrum has wronged the calculations, only he knows if he has had that in mind, I say it is difficult to calculate. Anyway, if you have calculated it in a way with ALO it has done the same with the rest .... so it can be quite valid.

According to this article Honda has brought an update on the intake system and have largely solved the vibration problems by making the chassis work better.

I had a feeling they'd start getting their act together by Sochi, hopefully my other hunches are right as well. =D>

As last week I compared the best lap of Ham (or pole position) in Q3 with the best lap of Alo, last week the distance was about 3.2s, this week the difference has been 2,649s, a Improving 0.600s, as Goldmeroso says, considering that this circuit calculated that it would be worse by its characteristics, if they have taken a good step forward.
And Vandorne was out-qualified by two Saubers.
Stoffel has had bad luck with the accident of Giovinazzi, I think it would have happened also to the q2
Giovinazzi was going faster too, before his spin.
As was Ericsson.

Grosjean was on track to get into top 10, as was Palmer.
Verstappen had some engine related issues.

Ocon was about matching what Perez did, which would have put him ahead of Alonso.

So, if Giovinazzi didn't spin Vandoorne possibly would not have made it into Q2, and possibly would still have been beaten by two Saubers. And if the others hadn't had issues he may have been on the last row.

Are you sure about this? When I put it through Google translate it does say an updated intake system here, then says they will bring other updates to bring more performance as soon as their ready but not ETA on the updates for the big progress (so it sort of sounds like the intake may bring some performance improvement). It then mentions the engine vibrations have not yet been solved (& that their still upshifting above the normal/ideal range).
