UKGTR Season 10 Lower Endurance - Interlagos - Oct 25

[Simon Gymer]

I must have been really bad in a past life to have this much bad karma  :'(

No, just this one...you naughty, naughty boy!

[Legzy]

that is tough mate. next season buddy!

[Blunder]

Picnic, must have been your car... I'm guessing that was frozen....!?
Was behind other cars so didn't see you until too late..
2 flat tyres, race over!

 

[picnic]

Sorry it ruined your race too

[Blunder]

Not your fault buddy!
Shame you had the issues 
Shame about the championship!

The race itself was pretty boring for me, except the fight against Lazlow in the first half of the race. I had some good racing with him until he eventually passed me. After the pit stop, gap to Lazlow was about 20 seconds and the gap to Prof was about 30 seconds. I had also a very scary moment, with only few laps to go, when I did hit to a lagging car and went off the track. Luckily, I survived with no damage. Finished 2nd which was a good result to me.

Picnic: Bad luck mate. I wouldn't have wanted the championship competition to end like this.

About the season. I managed to achieve my goal which was to get a podium place in one race. So the season was sensational successful to me! I had many awesome fights, especially against Picnic, Lazlow and Dave. Without the incident in Interlagos, Picnic would be the champion. Bad luck mate! :'(

Congratulations Gazza for the GT2 drivers championship and Team Shark for the teams championship. And in the GT3s, Team Oldie won the championship. Go Team Oldie!

And most important, I want to thank people who made this season possible.

Had a first semi-good race this season.

Reason was simple, changed to F430. I can't drive M3 GTR, period. Mind u, this was my first race in Fezza, only drove it for few laps round silverstone when it got out. Great little go-cart, that explains it's pace, it's grip is simply phenomenal, thoroughly enjoyed driving it.

Race was... weird, both SBG and I were long in first stint and lost heaps of time due to it. Still can't figure it out. 

Anyway, great championship, great racing, you're all a bunch of real gents and that makes racing a pleasure, so thank you all.

Congrats to all the winners and such.

Well I don't know about you but I know why SBG lost loads of times. Driving the Lambo he has to stop a lot longer in the pits because he needs to take on more fuel due to the car being a lot thirstier than some of the other cars (like the 997 I was driving).

Looking at the lap chart, his in-lap is very good, but he takes 24 seconds longer than someone like me in the pits. Ultimately he makes that up in outright pace, so despite "losing" that chunk he has made the right car choice for him because he can drive the car fast enough to make up for the extra fuel.

This is what's good about having the different car types and people with different abilites; speed on the track, consistency on the track, good at pit stops (yes it's not all about the amount of fuel you need or the tyres you need to take on!) and so on.

I also changed tyres, whilst I'm guessing others didn't? Thats always a tight call in GT2 for me. I wasn't really losing any pace at end of my first stint but after about 70 mins my med/med combo normally turn to mush. In GTR2 tyre wear feels like it suddenly goes from good to utter disaster with not much graduation between. Or its so gradual I might be missing it

I ALWAYS change tyres, even in GTC. I was running soft-medium in the 997.

I didn't in this race, but then I also lost 3 positions in the last 5 laps because I couldn't hold my lines well enough with the shot tyres

[Jure]

Well, I came into pits with 2,5L of fuel, changed all tyres and put in additional 45 liters. Finished with 0,88 liters of fuel. 

Pit-stop time was 45 seconds (lap 2.33), in lap was amongs the best, hence  .  Practiced pits prior to race, I always do, that's what makes it so strange, I know I was right on the money. I did lose few seconds in last few laps due to traffic prior to pits, but generally speaking the same lap times were still pretty good. Weird.

Lap times do explain it to some degree, main competitors had roughly the same pace (sad it during last few laps prior to pits) but were on warmer tyre once I got out (behind Gazza). Was on M-H tyre (overinflated but still too cold, lol).

Anyway, F430 it is. Noob car you say? I don't care, that's how a car should behave. I love it.

Well that's your problem. To work out your starting fuel you need to work out how much time you lose carrying additional fuel against the time you save not having to put that fuel in during the stop. If you simply fuel for the stint you haven't done your homework.

Oh but I did, even did comparative fuel load tests b4 the race and was even toying with an idea of full fuel load (90 L I believe) for late splash&dash (tyres could take it). You see, I love details in racing. Perhaps you're right and it should have been 90L (which would mean I'd still have to fill some 20 or so).

Comparing 57/57  liters or 70 and 45 (with exact fuel for each stint) it came out (in theory at least) in favour of a longer first stint (preference wise, maths show the same cumulative time). 18 liters of fuel @ 3 liters per second (right?!) for 8 laps of fuel less = 6 seconds saved. Longer first stint ment extra 0.2 s per lap. Times 32 = 6 secs, therefore 50/50 or longer first stint come out more or less even, but I should have been gaining while rest were in the pit stages. Must have been traffic then, plenty of 1.34s due to it (which is good, am not complaining) in late 1st stint (saw my competitors slightly gaining too, but were all above 1.05 mins). I was very fast at that stage, but couldn't run at max due to traffic, that must be it. Gap graph @ lapchart info clearly shows it tbh. I wonder how it would go with full fuel load though, should still be able to keep it well below 1.34 (if alone that is ).

Well, Jon breathing down my neck sure didn't help either, but that was in 2nd stint anyway. 

Plus I lost 7 seconds due to a semi-spin and stuff in early stages (not to mention positions) but that's not the issue.

Mind you, I was fully expecting 47 laps only. The only reason I've finished the race with assigned 45 liters of refueling is the fact that I managed 3 more laps than predicted in the first stint, lol. 

Simon, how much fuel did you take on during your pit stop? Even during the race itself I went "LOL, cool, I wonder how the h did he pull it off??!?!?!", cause u were right behind me before you've pitted, then I saw you waaaay up-front. 

[Simon Gymer]

Simon, how much fuel did you take on during your pit stop?

I couldn't exactly tell you as I wasn't taking notes, I would guess it was 15-20 litres. I started on a full tank (100 litres) and filled back up to 61 litres just after midway. I could have got away with not filling up quite as much but after seeing TT run out of fuel so many times I always would rather finish with far more fuel than I need than run out of fuel with a lap or two to go. The difference between running with 5 litres on board and 15 litres on board is so little it's not worth running it so close just for a tiny amount of lap time.

I might be making these figures up cause every race the stats merge into each other after you've done so many, in qualifying I think I was using 2.2 a lap and in the race I was 2.0->2.1 a lap.

I was consistently faster in the second stint than the first because of shedding some weight in the first stint. Looking at the lap chart this means I gained 3 seconds on you in the extra 3 laps you did before pitting. That's 1 second a lap on pace alone just because I pitted earlier.
