Mclaren MP4-30 Honda

The Carbon resin can be impregnated with aluminum if they ever needed to (check something like thermal paste with aluminum filings in it). And gold foil is very conductive that is true but it is a heat reflector first of all.

Cooling is not Mclaren's problem. Heating of parts that cannot be easily cooled is their problem.
Their problems is parts that are in an extreme heat affected zones. Parts tucked deep into engine... Boreing some holes would not be enough. They have to redesign those parts that have the "hot spots."

Intersting,so i guess the whole "seal" story from testing was just a cover up story for media!?

Gold is used as a heat *reflector* since it's used mostly to reflect infrared frequencies. This is why the F16 canopy and astronauts' visors are coated in it. You use gold leaf to protect what's underneath.

You have much cheaper and MUCH better materials at heat dissipation in copper and silver. Silver is only surpassed by diamond.

Don't confuse the uses.

No the seal probably failed because of heat issues it may actually still be the biggest problem.

Probably a stupid question, but can they not use heatpipes or do teams already use them?

So what you're saying is cooling is not the problem. The problem is cooling. Hmm...

They are having issues dissipating heat, so cooling is the problem.

Either the cooling system McLaren provided is not working as promised, or they are seeing more heat to certain components than they simulated on the dynos.

I think he said, and I took it as cooling isn't a problem generally, just that there are specific hotspots around the PU where the design of components near to these need to be adjusted so that they behave reliably in the hot conditions.

From what has been said, it seems like outright cooling of the unit isn't an issue - radiators, oil coolers, manifold heat, etc, are all fine, just the odd specific components that are having trouble dealing with heat in some spots, presumably the recovery systems and the control units buried deep - that may not require more cooling, but perhaps a redesign of the components to be able to work in higher temperatures, if possible.

Why is it that McLaren were running in fuel saving mode during the race? I thought that the fuel utilization by the engine should be lower since PU was detuned? Does this indicate that Honda PU is not fuel efficient?

The MGU was disabled. For example; if the battery on a Prius is dead, the engine will have to work longer/harder and so consume more fuel

[GoranF1]

According to BBC the MP4-30 was around 200BHP detuned in Australia....which is more than 3 seconds in pace.

I have a feeling that Alonso is going to destroy this car this season as he has nothing to loose.

Jensen will drive sensibly to get the car home

Alonso is going to drive crazy push it beyond so see what pops (Pirelli, Honda or Mclaren)


going to be incredible

I was being kinda smart with my post above. But if you have components that have trouble with heat (overheating) then you certainly have a cooling problem. You have a problem cooling that component.

I read on another forum someone posted the Honda PU ran reliably with 100% Honda parts and at Mercedes 2014 power levels on the dyno, but once it was put in the McLaren chassis, McLaren used some McLaren parts that Honda was not aware of thus leading to some of the problems they are having now.

I find that slightly hard to believe, but you never know.

That seems a bit far-fetched if I'm honest, other than the case when the Honda components could, for some reason, not be fitted to the car. Other than that, Mclaren would have switched to the Honda parts immediately after theirs would have failed.

I'm guessing they are refering to cooling system components, like radiators, etc. I can't see it being anything more than that, and it still sounds a bit sketchy to me.
