Honda F1 project leader Yusuke Hasegawa has outlined a number of reasons why Honda has been struggling so badly in the beginning of the 2017 Formula One season. He confirmed that lots of problems were not discovered while running on the dynamo meter.
If that was the case I would expect better qualifying performance. I don't think the PU is competitive in peak performance yet. It certainly is a bit off the mark when in fuel-save mode relative to the rest.Postmoe wrote:IMO they have good peak power since Abu Dhabi 2015. In every single occasion they had the option to run rich they nailed top 5 laptimes, isolated or during 2-3 laps.
This is NOT a VW/Porsche dyno. It's a 3rd party company called Schrick GmbH. They do development work for numerous manufacturers and/or dirtier jobs where a manufacturer's "expertise" hits a dead end, they finish/correct the development.FW17 wrote:Great find. More reasons why a company with expertise of Porsche VW should join F1.
The interview is from a Spanish newspaper so he probably just mentioned Alonso, or they asked in the context of Alonso.enkidu1978 wrote:I kind of have a sick feeling about this comment though...

I think we can assume also that a better combustion on lean + a better energy harvesting is key in the so called qualy mode, specially during the instalation lap. That could explain why Honda underperforms in qualifying but is able to have short bursts of raw power during the races.dren wrote:If that was the case I would expect better qualifying performance.

Also, Honda was interested on Alonso as soon as 2012 if my memory serve me well, I actually think it was some sort of demand from Honda to join McLaren. That´s the reason Alonso´s salary comes from Japan, Alonso really is Honda betzac510 wrote:The interview is from a Spanish newspaper so he probably just mentioned Alonso, or they asked in the context of Alonso.enkidu1978 wrote:I kind of have a sick feeling about this comment though...

It'll be more than 1G max, but not sustained. (If you want sustained g, you'd need to build it in such a way as it could be rotated, like in a centrifuge).Andres125sx wrote:BTW, that gimbal for engines is quite interesting, but I´m not sure if the max 1G it can simulate is worth the complexity compared to normal dynos. Also, to produce 1G it needs fast rotations wich may affect some liquids (oil, coolant) on a different way than on a track where there´s no rotations at all, and Gs can be three, four or even five times higher.
For road cars that gimbal is great as it can simulate lateral accelerations of road cars (max 1G more or less), but for F1 where the PU will suffer 4-5Gs...
Dyno testing is necessary, but as a development process wich must include track testing too
I don't think the 1G is a product of inertia. It simply means the engine can be tipped over so that earth's gravity (1G) can be applied in any direction. This simulates the main problem for engines in coping with on-track forces which is the apparent inclination due to lateral Gs. The magnitude of the resultant force is of little consequence.Andres125sx wrote:BTW, that gimbal for engines is quite interesting, but I´m not sure if the max 1G it can simulate is worth the complexity compared to normal dynos.

It would be more efficient to use optimal timing and harvest from the MGUK.NL_Fer wrote:Honda's qually mode seems to be powerfull but fuel thirsty. Would they be running late ignition during part throttle to keep the mgu-h harvesting enough energy, for running a full lap of mgu-k?
We are developing all the time,” admitted Hasegawa, “and if we didn’t need to worry about the tokens we would be prepared for this upgrade.
“But at the moment we have not finalised the (token) plan yet,” he said.
Marca cited sources in saying the next upgrade is already on the test benches.
