Regardless in Spa they would get mauled in sectors 1 & 3 and only hold off the Williams under braking and in sector 2.

Sorry. It was more than that! First off If i remember correctly Alonso was using some special engine mode on start/finish stright and (or if i am not remembering it correctly) Alons still has best speed on S3 exit(start/finish line) F. ALONSO 223.8

He made so much distance in Start finish straight that it was enough to hold off williams until end of Kemmel straight.

Under braking for the bus stop and La Source

Can someone point out the battery pack in this below picture, Is it under the section of the ripped floor just ahead of the plank?
Is the silver casting that of the engine or gearbox?

I would imagine it's at the back of the car.

Of course breaking, that too, but highest speed at start finish line points to more than breaking!

[godlameroso]

The start finish straight is right after the bus stop and right before La Source, which means they come out of slow corners decently enough.

To achieve top speed on finish line Doesn't matter how much You break into corner! in general the less You break the faster You are!
To be fastest on start finish line there could be 2 things - better acceleration or better(higher) corner exit speed.
Breaking is not factor here - its a factor in laptime but not in top speed! unless You want to say that everybody else "overcooks" corner (if You know that term)!

@joseki - I do know Honda has a chassis dyno placed inside a wind tunnel. I do not know if the climate can be adjusted in the wind tunnel. I do not know for sure if the MP4 with the Honda PU has been tested in there but I would imagine it has. BTW is your user name the Japanese meaning for joseki? If it is, I like it.

Hi Wazarisan

So are other engine teams and Honda using this setup now? How much of the MP4 do you get to test the engine on?

Also what is the reason in your opinion that only the Mercedes works team is using a water intercooler while the others have not tried it. Even McLaren in 2014 did not try it.
If a water intercooler is adopted with the Honda engine by the team does it offer any added to the chassis an engine.
Ferrari solution in 2015 was compact and neatly packaged, but was it undersized or the reason it was changed was only to accommodate the VLIM

I hope this is just coincidence but we just received a memo as to what we are not allowed to speak to about certain subject matters in public. Two items specifically mentioned were testing equipment and times, and other team's design. The timing of your question is curious. So sorry can not address your inquiries.

Generally speaking, with intercoolers in a F1 car, packaging would be the biggest criteria, then heat exchange properties of liquid vs. air, then weight.

Should I have asked a bit earlier I guess


I wish Honda would post something outrageous to spook the others

I think that was done at times in 2015 and it didn't go so well....

With better more precise braking you can set the car up better for the exit which lets you carry more speed down the straight.

Think about where the start/finish line is in Spa, it's at the end of the bus stop, you go into the bus stop going 310+kph to 65kph, then a slow left with a tricky exit, going up-hill, and about 400 meters after the start/finish line is another heavy braking into La Source.

McLaren Honda was pretty decent at stop and go style turns, that's all that top speed at the start/finish says.

Will we learn about the new turbo layout at all this season? Will we get a peek during testing or perhaps the first race of the season? Or is the new found flexibility regarding development mean that any unique solutions regarding the turbo would be to risky to even discuss at a conceptual level?

I think these are all questions that will be answered by someone above my pay-grade. I think some of you might be surprised at the turbo layout for next season. I think they will try and keep the public from getting any peeks during testing. Sakura is like Fort Knox right now, at least in the F1 PU division. Unique solutions.....hmmm, maybe highly refined solutions might be a better way of putting it.

[diffuser]

There will always be some of us surprised about anything!

Thank you! And I hope you've had a good holiday. The block is getting hot-tanked on Monday, and hope to have all the machining done by next Friday. I have to make small reliefs at the bottom of the cylinders to clearance the new crank and rods. I also noticed the piston oil squirter jet for cylinder 4 was improperly installed from the factory, and the banjo bolt was not aligned with the squirter jets, surprised the block made it as long as it did(180k miles), I'm upgrading those since everything is apart.

Thank you I did. The K/F series engines are very stout and can take lots of abuse. 250+ HP, here you come!!!!
