Honestly I dont remember where I got the idea, I want to say I've seen video of it but everything I've found since shows fuel being cut as well. I'm no engineer so dont take my words as gospel.henry wrote: ↑23 May 2019, 08:20Do you know this or is it conjecture?Maritimer wrote: ↑23 May 2019, 01:32Ignition and throttle are unaffected, the ecu just cuts spark timing accordingly.saviour stivala wrote: ↑22 May 2019, 14:24I believe that the ignition cut-off has been done away with by the use of seamless gear change gearbox.
There are many other potential tools available to the PU engineer. They have recently been discussed in the Honda PU thread starting at viewtopic.php?p=832854#p832854. It’s a rough ride in places.
With the current direct injection they definitely cut or lower the fuel as well, not only gives this a little saving, but imagine how "wet" everything (spark plug, injection chamber, turbo, etc) will get when you'll have a couple of revolutions without ignition.Maritimer wrote: ↑23 May 2019, 08:34Honestly I dont remember where I got the idea, I want to say I've seen video of it but everything I've found since shows fuel being cut as well.

Anyway, the big teams won't lower their budget or staff, just invest in different area's that are still free. The current tenders could be divided in two I think, on one side stopping some ridiculous complicated developments like the rims and on the other side tech where no real gains are but are quite expencive to develop from scratch, like gearbox cassettes, pedals and steering rack. These are items teams run for years without redesign. This makes it a lot easier for new teams to enter and helps teams that don't have a big sister.Zynerji wrote: ↑23 May 2019, 01:06The cost-capping talks have ALWAYS referred to reducing team size.Just_a_fan wrote: ↑22 May 2019, 09:06Yes, I know all of that, but what has the cost of F1 got to do with you? Is it your money that you're trying to save by having them make people unemployed?
And to say "it works well" as a system, only applies to one end of the equation. The business owner does well out of reducing costs, the people they dump on the scrap heap, less so.
F1 is NOT a union. No one has the RIGHT to work in the sport. No one has an OBLIGATION to continue to employ unnecessary staffing.

Where did you get that from? I know from very reliable sources that Mercedes GP make their own transmission gears while engine timing gears are made by PTI and their hypercar gearbox is indeed fully designed and made by xtrac.Jolle wrote: ↑22 May 2019, 22:04Mercedes runs Xtracs gears, funny enough they are one of the few that outsourced their gears outside F1.Mudflap wrote: ↑22 May 2019, 21:52Why the Merc gearbox though - they are the only manufacturer that cut their own gears as far as I am aware ?
At the end of the day F1 manufacturers compete to showcase their engineering prowess, any move towards standard parts is really against the nature of the sport. I would think a good chunk of F1 fans want to see the most advanced machinery going all out on the track.
Since a few manufacturers believe (and for good reasons) that they can build better gearboxes than what the likes of Xtrac have to offer I don't see why they should be stopped.
It is a given that teams will always blow every last penny available so introducing spec parts would only shift their spending towards lower gain items.
Of course it’s also quite possible that a party like Williams (probably the reason they didn’t close that department last year), RedBull, McLaren and/or Ferrari have made a bid.
I might be mistaken but it was on the Mercedes F1 and Xtracs website, what surprised me, because I thought that a team like Mercedes would cut their own.Mudflap wrote: ↑24 May 2019, 02:02Where did you get that from?

The reason some teams stay away from xtrac is to do with the fact that they only manufacture (or used to) a single pressure angle for their high performance spur gears and are also very conservative with gear sizing. By contrast MGP have their own in-house gear and bearing calculation software as well as manufacturing capabilities.
I think it's a horrible idea. F1 is all about each team having to build and prepare it's own car and the world doesn't need another spec racing sport where everyone runs around in the same machine. That's really boring.DiogoBrand wrote: ↑27 Mar 2019, 19:52I think it's a good decision. F1 gearbox designs don't translate to road cars, they are relatively not very interesting, and standardizing them will also allow for more compatibility between power units. The fact that the teams will be able to develop their own external casings is also good.

With each new rule like this, the foundation upon which F1 was built deteriorates more and more. Eventually all these alterations will add up to a sport that is no longer recognizable as Formula One.
We're getting close to that now with freezes on engine development, engine restrictions, fuel flow limits, the Mickey Mouse DRS concept, and on and on.
