1y ago in Australia there were severe upshifting problems with the engine&transmission

Is that what we're hearing in that video?

Here's the sound in Australia 2017 free practice.

Sounds much worse in this video but it's definitely the same vibration on upshift.

It runs!

[etusch]

a good start to new partnership

[Maritimer]

The fluttering is caused by the gearbox isn't it? You used to hear it quite a bit with the V8s. Driveline shunt yeah?

[ArcticWolfie]

It's difficult to tell because;
-Bad weather
-New exhausts
-How good is the recording mic?

We will see next week.

They may have tuned it that way to make sure the shakedown went smoothly. I will look for tighter shifts as testing progresses. JMHO.

Not even pushing.

Sounds so different! Things are getting exciting!

Could be a bit of engine mapping too. Need Wazari to confirm what it is.

Agreed, surely some calibration going on. This is the first time the Honda PU has used a completely different gearbox. But I also wouldn't mind a quick pre test Wazari update

I really haven't heard anything that's newsworthy IMO. I hear everything is on track, going with slightly more conservative "4.1" PU at season's start. Rumored that at least one "version" of built PU has exceeded 700 kWh but just a rumor...........

700kW is less than 940hp... I guess that version doesn't excell in terms of reliability

That's fair enough actually. Conservative start is probably a smart move. Keep things rolling at decent but safe pace while development continues for down the line.
Curious about the "one version" line. Are you talking like a spec 4.2/3/4/5? Or are you suggesting one of the 4.1's built has hit 700 on the dyno?

Wazari since you said that Honda have identified new combustion process which others cannot copy. What do u think the likes of Renault are doing to get over 950 hp at the beginning of the season? Merc were doing it last year. I had a feeling anything less than 950 was trouble for Honda and it appears they have not delivered again at the start of season.
