I think it's the combination of compactness and the curves like 2JZ, RB26DETT and of course the Turbo fan turbo intakePlatinumZealot wrote: βSat Jun 18, 2022 5:17 pmThe Honda engine has the typical Japanese engine look. I just can't put my finger on what it is exactly? Shiny black parts and lots of square shapes?
Well they do but not like that. The Subaru system I would think wastes fuel which is the enemy of this F1 formula.DutchPanther wrote: βTue Jun 21, 2022 2:11 pmAre there any current F1 engines on the grid that basically have an antilag like the Subaru rocket antilag system?

Yes, I thought the same, just spool up the turbo to get a better launch using H unit, while the Subaru used fuel and the pressure tankRoostfactor wrote: βTue Jun 21, 2022 7:51 pmWell they do but not like that.

Instead they use the MGU H as an antilag "motor" when needed then it will switch to "generator" when needed to help charge the battery.
That is the simple answer as these systems are very complex and can change mode very quickly.
Yes I heard about that, apparantly the Honda was using it's big turbos as a flywheel to hold the energy (I think it was the CAC bypass 2, not sure..), if that is true, I think the crackling sound makes sense also, it certainly made the Honda the best sounding engine!etusch wrote: βWed Jun 22, 2022 8:20 amThank you for sharing this video.

If I don't remember it wrong, during 2020 preseason tests honda pu was making poping sounds during braking. @godlameroso shared something and after that we started discussing some ideas which will burn fuel during exhaust strok to push it to directly turbo to spin it faster so the electric motor which coupled with turbo to genarate electiric, which is quite similer to subaru's "rocket antilag" system.
During season the sound was not there. I remember a statement of honda F1 boss when he was talking about das system of merc. He was saying they wanted to implement some innovations but fia refused. The ideas we were talking about was just our assumptions about that poping sounds and we can not say Honda was doing one of them or doing something like what subaru made. But again as an assumption of mine, I thought Honda wanted to implement something like that and Fia refused.
I dont know what you mean by "core engine characteristics" but yes that's what the different strat modes and other switches do, change how much mgu's recharge (generator) vs adding to output power (motor).DutchPanther wrote: βFri Jun 24, 2022 10:23 pmFrom what I understood, the Subaru basically treats it's turbo charger like a turbine engine while, most F1 car use the MGU-H as the driving force for the turbine. As Hoffman said (which I imagine is what most teams probably do), if the turbo pressure is to be a constant, then definitely the H unit is being used as a motor. But that said then, won't they be able to change core engine characteristics with a switch?
F1 engines are this way as well. They run a ton of air through them.DutchPanther wrote: βFri Jun 24, 2022 10:23 pmFrom what I understood, the Subaru basically treats it's turbo charger like a turbine engine while, most F1 car use the MGU-H as the driving force for the turbine.
