Honda Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

I don't think so. Honda does use a "waterless" coolant formulated for them but I would think the other manufacturers are all using a similar coolant so I don't think it would that far ahead of the others if at all.
Thx Wazari,

Hope things are going better. If I may ask a second question: how do likely do you think the mentioned plan is to use TR as a testimg bed for 2020 specs during the last races? And what do you make of the image posted above regarding dual inlet and outlet turbo’s?

New spec incoming, have any of you noticed Honda has no reservations giving money shots of the power unit once a new one is rumored to be around the corner.

Interesting about that gap between the exhaust and bodywork, and how it tapers down. I know what that does. :twisted:

If this keeps up Verstappen is going to know what Marquez in Moto GP has been feeling the last couple of years.

This power unit has taken a nice step forward, it's so beautifully constructed. The oil tank =D>
I'm a total engine-noob, can you highlight the oil tank in the Honda-PU for me?
You won't catch me driving a race car that I have built.

Is this new information? Honda has shown this since the beginning of the season.
Dual inlet, dual outlet, split turbo physically connected and it's orientation.

At one glance you can instantly tell that that thing does not work. Graphical materials for this sort of things are just casual diagram, same as tube maps, anatomical explanation drawing of organs etc, not something to take serious about.
Telling orientation of turbine rotation is so easy, just look at its body will do.

Obviously, they are not showing exact details. All I'm saying is this information is not new. Dual outlet and dual inlet that is.

It's at the front of the ICE, it is moulded around the compressor. Compared to the design they had on there 2 years ago this is light years ahead.

you proposed 2 compressor outlets which would add rather than eliminate pipes ?
Demarcated with the orange arrow showing compressor outflow. Second image below. It is of apparently the same diameter as the left-side outlet, which you acknowledge to be an outlet. It's flange is treated the same way, with two white o-rings. Do you have another suggestion for its purpose?

Most photos of RB cars from the past six seasons with engine cover off will show the thicker-core a:a intercoolers mounted below the thinner liquid radiators. These are mirrored about the car, one per sidepod. Compare to Force India who dedicate an entire sidepod to one a:a intercooler. RB, Mac and Renault altenatively fill half a sidepod on both sides.
They do this presumably to balance weight and aero loads, as well as optimizing flow to both cylinder banks.

2018 plenum. Inlets point away from CL, toward outboard intercoolers. Unlikely to be sequential/series flow.

You are right, you've convinced me.

I do struggle to see what the advantage of splitting the charge air cooling for the 2 banks is though..
How much TQ does it make though?

looks like honda is using an air to air intercooler rather than charge cooled like on the ferrari and mercedes amg..maybe that is why they have resorted to two outlets on the compressor wheel. interesting that single turbo has two inlets for the turbine and outlet for the compressor, bit like having twin turbo

Hi @Wazari, see my above post. Are you able to give info on this? Thx and all the best.

At this point, I don't think so. They are still testing specs that I think were intended for 2019, not 2020. Although slightly ahead of schedule, 2020 Specs will probably not be ready until this winter. As of 4 weeks ago, there were 2 upgrades still planned for this year. One minor and one major. I imagine they will be introduces to both STR and RBR at the same time.

I don't understand what you mean "make of the image...".

Someone posted a CAD imagine of the Honda basically having a twin turbine set-up which looked weird.

This is an English idiom. In this case, it means "what's your opinion of the image".

Max just said the FIA ordered them to box and change PU settings. Very curious what this is about. Source:F1Maximaal (Dutch)
