Spec 4 is coming out in October, no engine upgrades are scheduled this weekend where are you getting this info?

"Force India isn't the only team with driver problems. Again, Fernando Alonso had trouble with Honda at Spa and he's clearly now at the point where he's fed up with the situation. He wants to be in a competitive package and he does not have that with McLaren-Honda.

He's made some pretty poor decisions lately, is he about to make another one with his career? It looks like he might have parked a healthy car at the weekend, and that's never good for team morale - not that anyone in the McLaren garage is happy with the situation.

To add to Honda's problems, I don't understand why, for some very strange reason, when everyone else removed the most draggy parts from their cars, McLaren continued to use such parts. With a car that we all know - and as Alonso keeps reminding us every race - doesn't have the power of the others, optimising it for the mid-section of the track means that it is sacrificing performance in section one and three.

I believe a better compromise was there to be had. Would it have made much difference? Probably not but it would have meant it might just have been able to hold its own on those long straights just that little bit better.

After all, Alonso confused his engine in qualifying by taking Pouhon flat, which again suggests the balance wasn't right."

IMO, two main issues still remain, ERS system management and ICE fuel efficiency.

and this is the point where I say that what is being called back pressure is not really back pressure ......

if the induction pressure is 4 bar and the exhaust pressure is 5 bar that's back pressure
if the induction pressure is 4 bar and the exhaust pressure is 4 bar that's not back pressure
if the induction pressure is 4 bar and the exhaust pressure is 1 bar that's forward pressure

the back pressure mystique comes from NA where in most driving (because it's throttled) there's back pressure (useful for control of course)
I am assured that car turbos do not have back pressure


because of the MGUH F1 can have back pressure, neutral pressure and forward pressure

I think Honda is fighting Alonso and Mclaren. If Mclaren is pushing Honda to quit formula 1, putting more drag is the best way .. But it would not change much the situation, as the article says. But Honda will make it much worse.

Curious about the ERS. In your opinion, are the individual motor/generators not the issue, but the controls and interaction between components? I'd assume, based on Honda's history, that the MGUK and brake regen is fine. Perhaps it is an energy flow bottleneck as has been talked on here a lot over the years of this formula.

Everyone is confusing the naming. There is very little new info.

IMO the management of harvesting heat/exhaust energy to the MGU-H unit and the relationship of all the components involved in the ERS needs to be more efficient.

Spec 4 in my mind is the major upgrade hopefully coming later this season; not small upgrades that may be introduced this weekend.

Hasegawa:

- "Especially this time we have raised the low speed torque considerably and the low speed torque at the start and the start from the low speed corner is about as much as a mini car."

- "Since Spa-Francorchamps is not a place to use it so frequently because there are few low-speed corners (because it is a low-speed area), as performance does not go straight as it is, we assumed that the gain is about 0.1 seconds, but in fact I went even more.I think that I could go up to 11th place in the qualifying at such circuit thought that there was effect of spec 3.5. It was difficult to see because it is Belgium, but if this is Hungary the result is different I think that if you negotiate between Belgium and Italy, I think I can go to a good place in the race in the future.
