Honda motorsport boss Yasuhisa Arai has claimed that it is unfair the engine maker is receiving all criticism and has rebuked doubts that the Japanese firm could make enough of a step forward over the next winter to become competitive.
yes , reliability over race and consistent pace was a big relief.Thunders wrote:Very good race indeed. If not for the Qualifying this would have been a great weekend. No mechanical failures all Weekend right?
A well needed good Performance to go into the summer break with an upbeat feeling. =D> =D> =D>
I think he must be saying they are 120hp down on average. It can't be 120hp peak. The engine must be really crappy if that was the case. So it may really be the ERS responsible. We've seen what happened with Kimi's car. How slow it goes around with MGUK.Wazari wrote:I think the most important result of today is that McLaren Honda got 140 laps of race data. It surprises me that Boullier says they are down 120 hp. I was trying to do the math and was trying to figure out where the deficiency is. The ICE is probably producing around 600 to 625 HP based on 1.6 L @ 15,000 RPM with about 3.5 bar of boost. Based on the fuel limit, I can't see them running more boost than that. The MGU-K unit has a limit of 50,000 RPM and 120 KW (161 HP) and max of 4MJ per lap. I figure that's about 30-35 seconds of max power per lap. So if Honda's PU is really 120 HP down, that means its MGU-K unit is producing only 30 KW. If that's truly the case, then McLaren Honda should be competitive with Mercedes and Ferrari once they solve the excessive heat issue generated by their MGU unit limiting their use power. That's of course assuming the chassis is also up to the task.
Specifically for this circuit the downforce is more important than the power. I guess that Ferrari, RedBull and Mercedes were running with more downforce than the client teams because the client teams have drive train losses, and they try to compensate with lower downforces. On circuits with more and long straights this is reasonable but when you are on slow circuit this is not good. McLarren have lowest available power but obviously they have good balance and low car frontal area that makes sense to run with higher downforce to compensate the lack of power. On Hungaroring and Monaco this works, on other circuits they are helpless. About yesterday I guess that RedBull had a little bit more power, too. Mercedes did a mess with tires and the strategy.Soichiro wrote:Hi everyone,
I am new here. I've been following you for a while and decided to join in.
There are some tech guys here that might know the answer. This race has raised a question - to me at least - is it really only on Honda to do the homework (clearly they lack power)? This is not a high power demanding circuit and the top speed traps were there with the Renault powered cars (faster in some and slower in others - but se sre talking small differences 1-1.5 kph) although Renault isn't much better than Honda, the difference to Red Bulls was HUGE! At moments, by the end of the race RB was lapping 3+ sec. Faster than Alonso and also set the fastest time. Also in qualy they were 1.5sec faster - I believe that is something McLaren should take a look into as to me it seems McLaren isn't that great eather.
Maybe someone can give a better explanation. Thank you.
i still don't understand why they took free engine this gp. they should have used that free engine as "upgraded one" and could have continued with same engine for which they took penalty. is there any rule that prevent them from doing so. by using free engine "as upgraded" they could have avoided penalty in spa.mclaren_mircea wrote:Is it rumoured that Honda will introduce an upgraded engine in Spa and Mclarenw will get a penalty on the grid?
. For starter.From the news read I would say they wanted to get as good a result as they could from the package - and they did. They assumed this track would be their best chance and it probably was. Also this enabled them to have as clean running as possible and get data for further development. In Spa - even with the engine upgrades they don't know if they will be fast enough and they cannot exclude reliability problems due to changes so I guess the end result doesn't really matter anyway.max_speed wrote:i still don't understand why they took free engine this gp. they should have used that free engine as "upgraded one" and could have continued with same engine for which they took penalty. is there any rule that prevent them from doing so. by using free engine "as upgraded" they could have avoided penalty in spa.mclaren_mircea wrote:Is it rumoured that Honda will introduce an upgraded engine in Spa and Mclarenw will get a penalty on the grid?
Still on a very steep learning curve“The settings on both the cars and the power units were solid, so this race was important for us in order to prove their worth.
not confirmed but rumor is biggest problem is MGU-K from the start of testing untill now.ringo wrote:I think he must be saying they are 120hp down on average. It can't be 120hp peak.
