Split 1 - R4: Donington - 13th November 2017 (1 Viewer)

[2scoops]

I just don't know what to aim for, especially in the wet with wet tyres. I've probably been paying too much attention to temps. I will have a look in Split 2 chat.

well from what i understand, @Puffpirat said for fuji if your tires are getting too hot then you lower the pressures but if too cold then you increase the pressures.

can you confirm this?

So you do a 1.10 in the rain on wets?

Nope. As per Puffy's post, the track is dry enough at the start of the session* to run on slicks and lay down a marker lap before it gets too wet to go really fast. For Puffy's reference, the lap was set about 7 minutes or so into a 20-minute quali session (after the session started, I ran nearly a lap before realising I'd forgotten to load my setup, I then did the outlap and 3 more laps before setting that time, so nearly 5 laps in total, plus pit exits and setup loading time).

Puffy does have a point, in that the quali session (as it stands) will be all about getting out quickly, trying to find clear air to get a good lap in, then sitting in the pits for 10-15 minutes. It won't make for compelling viewing or be a lot of fun for some of the drivers, once that initial madness is out of the way. We can go one of 4 routes I reckon:

1. Make it a properly wet qualifying - ie 'Rain' rather than 'Light Rain'
2. Make it a 'Dry' qualifying
3. Shorten qualifying to 10 minutes
4. Leave it as is and realise that qualifying is going to be 10-minutes of insanity, followed by 10 minutes of possible boredom

The only downside to options 1 and 2 is that we often have members practicing a lot, and they may well have a setup tuned to the 'Light Rain' qualifying. It's a bit late in the day to be changing it.
The downside to option 3 is that it puts a LOT of pressure on folk to get a lap in and, with 32 cars on track at once, tempers are likely to get quite short.
The downside to option 4 is the boredom of sitting in the pits for 10 minutes (or more) knowing that you have no chance of setting a faster lap once the track has started to soak in.

As for 'having a pre-qualifying session' running, that is wet (ie, Rain rather than Light Rain), I just tried 3 times and it appeared to make no difference to the track at the start of qualifying, so that's a non-starter by the looks of it.

I think the only thing we can do is learn from this for the future. Maybe either force qualifying to run in full wet conditions or only do qualifying in the dry.



* it's damp, at the start, but once a load of cars go out on track, a dry line starts to form quite quickly, leaving slicks as the ideal choice. But, once the rain starts to build up, the water starts to settle and even though a dry line appears, slicks become increasingly less effective.

That’s the post from Topsie, a small discussion about it is in the following posts

https://revolutionsimracing.com/threads/split-2-r3-fuji-6th-november-2017.1019/#post-21967

Just look at it like in iRacing. You don’t care if your tires are 80 or 120C you just aim for that hot pressure right? Same here.

Temps are a bit different here in pc2. Generally if you have two compounds, choose the one that runs better, eg the soft for low track temps, the hard for high. The soft likes to run between say 50-90 thread temperature, the hard from 80 up. Ballpark figures.

If you only have one compound, like the wet, you will need to drive around certain problem, eg take the downhill right hander at Donington slower if you cook it there. The optimal hot pressure for the GT4 tires (dry and wet) is 1.7-1.8 bar, that’s around 24-26 psi if I’m not mistaken

4. Leave it as is and realise that qualifying is going to be 10-minutes of insanity, followed by 10 minutes of possible boredom

everyone will set their laptimes early but some may do a 2nd run on wets to see if they can go any faster maybe hoping to make up a few places. personally i like the changeable conditions of quali, it makes it more tense and important to get a good first lap

 

[Puffpirat]

One remark to option 1: it’s the same problem as with light rain, only instead of going from dry -> light rain it will go light rain -> rain, track condition wise.

Ah damn I’d hoped a wet practice session before would change the behavior.

 

[Jamesl91]

i guess the game is designed to have no carry-over conditions which is a shame, theres nothing wrong with changeable conditions.

further to that, its a extra 10 minutes to make sure the setups are correct and to get pit strategy's sorted. I would certainly be out on track looking for any extra knowledge of wet conditions.

 

[Diluvian]

What about using x weather slots and set the first weather slot to heavy rain and all further slots to light rain (sync to race or how its called, so heavy rain only occurs 2-4mins?

 

[Jonno]

could we not change quali time to 25 and no one goes out for 5 minz meaning it will be wet..

 

[Cluck]

To be honest, I think it's too late in the day to be changing anything now for this round - as I said earlier, changing it now will penalise those who have put a lot of practice in. Yes, some people will get lucky and will get a quick time in at the start of the session, but there's a 45-minute race to follow and, with nobody knowing what the random weather slot will be, anything can happen.

All we can do is learn from this for the future. I suspect we may be best off just running qualifying in the dry in future.

NB : This is my personal opinion and not that of the RSR Admin (of which I am not part of anyway!)

 

[Jamesl91]

my opinion is leave it as it is. at the end of the day we are all going to deal with the same conditions so just get used to it... take F1 for example they dont suspend quali because of a bit of drizzle. The conditions are set at the beginning of the season and we just have to deal with it.

 

[Gopher04]

The temps and pressure thing is making my brain hurt..be nice..but lets not forget the random slot here, that could have a big influence for the race and we wont know that till the briefing, so I have 3 setups for this race now..

 

[Puffpirat]

Yeah just wanted to bring it forward so everybody is aware

im not sugesting we change things just set quali to 25 minz and have a 5 min ban for anyone then the track will be wet and no taking advantage of the dry track in the first so many minz its not a change its a compromise lol

 

[Jonno]

Woooo woooo wooo split one ill say no more lol

 

[Puffpirat]

well from what i understand, @Puffpirat said for fuji if your tires are getting too hot then you lower the pressures but if too cold then you increase the pressures.

can you confirm this?

Sorry this one totally slipped. Yes that’s correct. If they run hotter they will leave the optimal tire pressure window on the top end, so you would want to lower the starting pressure

Probaly a no show for this one. Having some major PC issues

 

[SharkyOB]

Another no show for me tomorrow night too. I haven't been on the forum enough lately and I missed that it was another single week gap between these two rounds. It's my birthday tomorrow so I'd probably have had to miss it even if I wasn't away in London with work.

 

[Ashnoom]

What are the issues?

 

[Hujkis]

I remember Donington from 1999 TOCA 2 Touring Cars, but that's about it really.
Did some laps in TT yesterday, looks like this track, with all the blind clipping points and bumpy surface is a lot about experience and practice - damn! And now I noticed, it's gonna be raining?
It's certainly gonna be interesting, looking forward for the race!
