2 x 14 laps.
Weather forecast (http://www.myweather2.com/Motor-Racing/Belgium/Spa-Francorchamps-Circuit.aspx) (looking like 17 and light clouds).
This is the round where you can SWAP CARS if you want (at the cost of 12 championship points). Post your car swaps here if you want to swap to the other car.
For this round, the fuel multiplier will be 4.0x.
-
Looks like there is a big strategy choice to be made this round, I only ran a few laps in the lotus and with my Misano setup I could only get 7.5 laps out of a full tank. So If I find some more grip and speed it will likely mean some fuel saving could be needed to simply make it with only 1 stop.

Of you could change to the Ferrari with its bigger fuel tank ;)
-
If there was no points penalty I may but its been hard work getting those points. ;D
I did run 7 laps and ran out at les combes so should be ok as long as there is no aero damage. That can raise fuel burn and so may force a 2 stopper for anyone in a lotus.
Looking at RSR the Ferrari is 1 second faster here but RSR really doesnt mean much seeing as I would have got the WR in the lotus with not optimal settings and a bit of fuel and fairly high aero. Im sure the ferrari time could also be knocked down a bit but the lotus guys probably will need to squeeze a bit more out of it to keep up with the ferrari here.
-
Here is the server times on the usual link, I will try lower aero another day but I think in the lotus at least it needs a bit of aero still. Eau Rogue and Blonchimont are far from flat even needing to brake at Eau Rogue. I really cant see me running much less aero as it will only make those corners slower and in the end give less top speed, the only time less aero really works at this track is if you can take both of those flat at lower settings where it will actually give you a top speed boost.

That's a great time Marty. I see the track temp is 27. Race night will most likely be light clouds, which will make the track temp considerably cooler, more like 15 degrees.
-
I thought I set light clouds but possibly not so will check later and change that if it isnt.

Maybe stracker is just reporting the track temp incorrectly too.

I just checked and using the acServerManager this is the weather it gives base road temp of 10 . So this means 10 degrees above ambient I think. I have disable ambient variation and road variation but can change this to whatever you set by default.
In the manager it has Realistic road temp as +5 for clear, -1 heavy Clouds, -2 Heavy fog, -1 light clouds, -2 heavy Fog, +5 Mid clear, and -1 Mid clouds. This setting can not be changed in the manager but possibly can be if done manually but its fairly simple to understand as it gets ambient temp + base road temp taking into account realistic road temp and any random variation that may be enabled.
Stracker seems to always show correct server settings and readings, unlike RSR which never did and current build doesnt show any settings at all making it fairly useless. These cars seem to get more speed in cooler ambient temps and so if someone really wanted to they could set very low ambient and higher road temps and be much quicker. That is why I would not pay much attention to any RSR times atm even though all times I have set in it have been rsr pro 26/36 100% grip. ;)
Also that speed comparison is showing f1 vs random trackday cars not gt cars as in the title. I find it quite interesting that the cars we are running atm are very similar in laptimes to the gt3 cars but done fairly differently. Top speeds are a bit higher in these f1 cars but gt3 cars have a fair bit more cornering speed.
-
I manually set the realistic base road temp to whatever the AC manager recommends for a given weather (and time). So in this case, I would set ambient to 17 and base road temp to -1, giving a track temp of 16.
-
Having a play in the manager I noticed now that time of day will alter the realistic road temp, Base road Ambient seems to default at 7 and Ambient/Road Variation is by default at 2.
Does that mean that you have base road temp at 0 ? and do you have the randomness in there or do you keep it fixed at 0 to set the temps you want. That would get you the 16 as it would simply calculate Base Ambient and realistic road of -1, then take into account any randomness in the variation figures. I assume they default Base Road Temp at 7 because it will generally be warmer then ambient in the daytime for the road surface.
I cant see how light cloud would actually cool the road below ambient temp during the day unless it was very windy, but whatever you want to set the temps at I will put on the prac server so people can at least get a reasonable idea of where it will be on the night.
Edit again I have adjusted the server to where it should be 17/16 with Base road temp 0 ambient 17 and realistic road -1 but can change if needed fairly easily.
-
Seems the realistic road variaton does nothing and its as you had it Wally needing to actually adjust the base road ambient to also -1 to get the temps. I thought the realistic road setting was applied automatically but I hadnt actually checked the ini file so assumed wrongly.

I did try some laps with this but also managed to get much lower track grip, I had issues getting front tyre temps up but some adjustments and this helped. I was only 1 second slower with 2.2% lower grip levels so possibly actually 1 second faster even if much more slippery, the more worrying thing is that even at this grip level my fuel useage went up and a full tank gets me 7.2 laps so with more grip I dont think pushing will make it on a 1 stop in the lotus. On the race nites though track grip starts lower and so early laps are a bit slower saving some fuel simply down to less grip needing to wait a bit longer for throttle on exit.
-
Wally: I have been testing a little and I did not manage to do 7 laps. It might be my driving style is not the right one (as Marty said he could do 7 laps), but usually I consume a bit more when I get into the right pace. the best I could do was 6 laps plus until almost the last chicane.
If I remember correctly, you wanted extra fuel consumption only to make sure we had to do a pit stop. Perhaps then we might reduce it a bit to make sure it is not just a night praying it is going to be enough fuel to finish.

Yes, I'll check it later. You shouldn't have to do more than one stop.
I wonder how much difference the air temperature makes to fuel consumption now?

Yes, this is how I do it. I always leave the temp variations at 0. It's only the grip that is a little bit variable, by 1 percentage point up or down.

For this round, the fuel multiplier will be 4.0x.
Marty, can you please updated the practice server.

Ok I am just changing the fuel multi to 4.0 now then.

I'm not sure why Spa needs a different fuel multiplier. The races are all about 30 minutes, so your fuel burn should be roughly the same.

I believe it has a higher full throttle % than most tracks we tried so far.

Same issues in modern f1 at faster tracks they need to save more fuel even though each race is pretty much the same distance of 300km. Monaco would use much less fuel the Monza or Spa, also the longer lap makes it more of an issue as with less laps over the same distance. I ran a race sim last nite on the 4.0 fuel and I think I needed 205 litres to complete the race. This is pretty much what all the other rounds have been in the lotus so far at 4.6x fuel. The main difference is the lotus only has a 120l tank but ferrari has 200, I wonder how close the ferrari is now to making it on no stops but the fuel multi could be made slightly higher if needed.
If it was allowed to not stop possibly guys in the ferrari could go a bit slower to save fuel and avoid a stop for a quicker net result avoiding a 35 second pit stop..
-
I tested the Ferrari too, and it won't be able to make it on one tank.

Yeah, less aero gives less top speed due to Eau Rouge and Blanchimont.
(Maybe with more car control than me it may work)
-
For me more aero is quite a bit quicker, I tried running less and gained .1 to les combes but lost 1.5 seconds the rest of the lap.
The key is more to find something that gives confidence in the car to push it quite hard, lower aero it was quite skatey to me through the middle sector longer braking distances and only 5kmh more with a bit less wing.
I ran a few laps in the ferrari too and seems they should be fairly close but in that I ran I think 7 5 aero, not much setup work where the lotus I ran a few laps lol. It is also quite likely the reason the fuel multi was too high is because 14 laps took me 32:40 to complete pushing fairly hard with only traffic costing maybe a couple seconds. I didnt actually tale notice of total time for races in other rounds but this may account for much of that. Still if Grat wasnt able to get 7 laps on a tank it wouldnt make any difference with the 4.6 multi as you still would need to get 7 laps in one stint in a 13 lap race.

Wally I might switch to the Lotus and give it another go. :)

OK, good to hear!

Can I switch to the 98T? :D

I think the only lotus's left are lotus 25's all the 98t's have been wrecked already.

Can't blame a man for trying. ;)
Hey Marty, I assume sTracker is running on the praccy server?
(if not, ignore the following)
For some reason, I can't access it about 9 in 10 joins, the icon is greyed out like in offline. ???
It is like that now and was the same yesterday when we were racing. :(
It just seems like a very temperamental app to me.
pTracker is great, I use it all the time over the in-game timing but it's a very rare thing to actually connect to sTracker.
(it seems a lot worse the last few months)
You know a lot about this app, is there something I need to do to rectify this?
Maybe Wally's suggested setup app maybe worth it if others have the same issue as me. :-\
-
Bacchulum make sure your running the latest version 3.2.9 I had it set to enable all ptracker versions but noticed it was causing some server issues when really old ptracker versions were being used by some people. Now it should only connect if your running 3.2.9 or newer so if you dont update then it wont connect. Im not seeing anybof your sessions as connected to ptracker so you kust have an older version.
Sorry I really should have made mention of this but since forcing it not to connect to old ptracker versions it has had no issues at all in the server.
I only made that change about a week ago to test and it seems to have stopped the fairly regular server overload that was causing all pings to spike. If I ever update syracker I will make mention of it in the prac server thread.
-
With the week's delay, it looks like it's going to be a fair bit warmer : more like 24 with light cloud. That should make it a bit grippier, and bring engine performance down a bit (I'm not sure how much temperature effects performance, really).
-
Ok I will change up the prac server to some warmer conditions. I did notice at Brands hatch that the lower temps made it considerably quicker. I did set an RSR lap though at Spa in 26c pro mode temps and I was quicker. In the prac server even though I ran a few laps none of them were really a qaully run mostly did full race runs there and only .5 off my optimum conditions lap.
The extra temp may in some tracks help with grip but will reduce power, with the higher fuel loads its hard to compare but maybe it will be a few tenths slower with some more temp. Possibly tyres may get a bit warmer and could overheat on a long run but I dont think it will make a significant change. If it was 34c or more things would get interesting though.

Server is up.
Weather is a cool 15 degrees for both races.

I dont see the server Wally.
Edit, my bad was a server filter setting.

Sorry Wally, I can't make it tonight :(

No worries Bafs, see you next week.

Apologies Wally, I don't know what happened there on Lap 1. From my point of view I was right behind you then suddenly it was like you either had to back off because of the person in front of you or I got a much bigger tow from you than I expected or a combination of both, but I literally had no time to react and suddenly I was tapping your rear. Probably I shouldn't have been following so close. Sorry to ruin your race.

I haven't looked at the replay yet - it's disappointing to go out so early in the race, but that's racing.

Looking at the replay, I didn't appear to slow. It looks like more like you got more tow than you expected, and just clipped my rear wheel.
