Notes:
(1) It's best if all drivers can make sure they are connected before the Qualifying session as drivers on track during qualifying will not see cars that join after they are on track until they go back to the garage.
(2) Please make sure you are fully aware of the SimRacing.org.uk Rules.
(3) The AI control should be turned off so that you have control of the car at all times, including pitting. Your player file should therefore read
Autopit="0"
Force Autopit Off="1" // Forces autopit always off
No AI Control="1" // AI never has control over car
If you still finding pitting problematic, experience tells us that its less to do with positioning and more to do with approach speed. A slow approach to pit crew chief has proved most reliable.

Special Notes: None.

Hiho,

short question, will the modern, current layout of Silverstone be driven?

Glück auf!

No, It's Silverstone 1970's version. Like it would have been in 1964.

I don't have sound engine in the Ford Falcon 64 ...... :no:

ygm

good news thx  :)

Just entered the server, with Robby online as well, and it showed me this:

Robby82GTL: Hristo Itchov "70Silverstone.gdb" mismatch

Is it me or Robby with the wrong version? Was there an update released since last time we raced these series?

The first name is always the first person on the server. The second name has the fault. The track has never been updated. Here is a link to the track https://drive.google.com/file/d/1r2ZpXjcAMxIZOYN1Elxmgp2FQ25WNmVw/view?usp=sharing

Thanks, Tony! I do have the track from before, not sure why the version is different though, if as you say there are no different releases or updates. I'll try reinstalling it and see what happens.

EDIT: All good now, thanks again

Results and replay now posted.

Two unremarkable races for me.

Race 1 mainly a battle with Fulvio. Early mistake by me let him past and I had to play catchup over several laps.  Started gaining and could reclaim my position when he made a mistake.  What sticks however, is Matt, a driver I'm usually close to, lapping over 3 secs faster.  I struggled hard to get into the 51s, so seeing after the race that he had dipped below 48s was quite surreal.  Had to compare the specs of our respective cars, but they were the same, so the mystery remains  :blink:

Race 2 I was split between continuing with the Jag or switching to the Alfa, the only other car I had prepared.  Chose the latter, when the posted laptimes in the short praccy by others in the same class indicated I would be competitive - and somebody had to try and prevent Matt from scooping up too many class wins in one evening!  :)   Race quickly turned lonely and I spent most of it trying to dip into the 47s, which I had done offline. Would have succeded on the last lap, if not for clipping the inside curb on that last, fast left-hander. Brought the car massively out of shape, and only prodigious arms twirling in a buttocks cleanching moment kept it under control  :o

Grats to podiums & class winners.

An enjoyable pair of races, if a little lonely in both]

Race1: it is a rare event that I can be faster than Erling in the 1st place, but unheard of to be, as he says ~3 secs faster  :o
I just seemed to get a sweet spot in the setup (which was the same as I have always used for the Leather Armchair)
And found it easy to boot out of the corners.
(You are welcome to my setup if you want to test retrospectively)

Race 2: Took the Tina, because I needed to use it, was not as quick as the Alfa for me, and Erling was on it, so he pulled away
and I pulled away from others, so was sat in no man's land

All good though.

That would definitely be interesting, so yes please  :)   Tried changing a few things in my own after the chock of seeing your laptime in praccy, but it didn't make me any faster and no time for more experimentation.  Tried following Hristo's advice of getting the power down early, but obviously not early enough, or not doing it correctly.

Awesome battle with Hristo in Race 2. From the start to the finish with hearth-stopping final corner that decided the victory. Unfortunately i had wrong setting in OBS for Discord, so you won't be able to hear Hristo :(

Race 1: it was clear that in this one I only could end in fourth place but due to DD's misfortune I finished in a lucky third place
after a faultless race. BTW: thanks DD for uploading your setup, but trying that I was more than 1.5 seconds slower compared with
the one available for me. So it looks like it's not only a question of the setup itself but also of the individual driving skills or style, game
settings and maybe other components on my side - the more as Hristo immediately was able to match DD's time after using his setup
which obviously is a good one  ::)

Race 2: did not practice with another car except the Falcon so I decided to use the Mini for this one combined with the GTL stock
setup for Spa which looked like a good decision. If I hadn't made this one mistake it would have been a nice one with Fulvio and Andy as
we all had the same pace.  :)

BTW: switched my online installs from an internal HDD to an external SSD (Verbatim Surefire - USB3). Was the first time online with it and
it looks quite ok.

Grats to the podiums and class winners.
This sort of series is what I really enjoy, a grid of vastly different cars and performance options.

However, despite discovering that I might actually be somewhere near the required pace in the Alfa to be competitive in it's class, my fun was interrupted in both races by what I suspect are hardware gremlins. At least I sincerely hope that gremlins are the issue and not me!!! lol

Grats to the Flying Falcon's Circus display at the front, they were just so much faster than everything else on track....kind of wish I had opted for some V8 power  ;).

Awesome battles with Dimitar and had a lot of fun joining him on the stream once again, even though apparently it didn't record my voice. It was hilarious at times going wheel to wheel and chatting about it at the same time. Dealing with traffic in race 2 and the way the final few corners on the last lap unfolded brought in some additional excitement!

Just tried the setup Matt has graciously shared with me.   His final drive is one notch taller than mine, the most obvious difference.  However, I'm only marginally quicker with it, my best being 1:51.266, compared to my fastest race lap of 1:51.570 (both setups with race fuel).

At a complete loss as to how he gains 3+ seconds - in all the corners I'm at the limit of adhesion; any quicker and I run wide. Brake as late as I can to still get the power down early - in most sharper turns, I'm on full throttle well before the apex. With the perfect lap, I could maybe gain a couple of 10th's, but 3 seconds...  :scared: :blink:

Even tried his car, to see if there was some hidden difference between them, but they're exactly the same. So in this case it's clearly not the setup, but rather the driving abilities of Matt (henceforth known as the JaaaagMaster) making the difference  :notworthy:

 :lol: :lol: :lol: I was not particular fast at Snetters, so it's not talent.
I think it was just at this track I could boot it out of the corners better than usual
with a bit of power drift.

Have a look at the replay, perhaps you will see some difference?

Just reading Erling's posts about the Jag, & not wishing to decry Matt's excellent performance, it did get me thinking. This is a race we did many years ago at Silverstone 70s.

https://www.simracing.org.uk/smf/index.php?topic=8784#event2235

This was with the 4.2 Jag Mk2, as you can see Matt is nearly as quick in the car you are using here as Navin & I were in the 4.2. Now I know that car used in this series is not the standard GTL Jag, but as I understand it is not the 4.2 one either, correct me if I am wrong Tony. Also at Aintree Hristo was much much faster than DD in the same car, now I know Hristo is quick but so is DD & the 4-5s gap between them did not seem right. Is it possible that some previous installation of the 4.2 Jag has somehow made the one used in this series faster?

That's a very interesting theory Geoff. Tried the old download links to see if there were cars overlapping the 3.8s we used, but the links are dead.

Matt:  Looked at the replay (again..  ;D).  You're braking later into T1 and upshifting earlier than me in places, so seemingly carrying more speed through the corners.  If I try that though, I fly off into oblivion.  Will have another go later and see if I can squeeze the lemon a little more, but can't conceivable see myself gaining 3+ secs.

I thought the same back at Aintree, Geoff, but then I decided to try DD's car and could extract the same pace out of it. The Jag is very particular in the way it has to be driven, constantly 4 wheel drifting it with a controlled amount of throttle without excessive wheelspin or sliding, keeping the revs at optimum range, otherwise it quickly loses a lot of time during acceleration and down the straights.

I remember the key thing at Aintree was NOT braking too late (though obviously you do need late braking for the slow corners), but rather rotating the car as early as possible. Nothing new, I know, but it was especially important with such a heavy car (similar to the Mustangs at Surfers). From watching DD's video of his 2 races back then, he was just not early and aggressive enough under throttle, keeping it too straight. Likewise for everyone else in the same car from what I could see.

You have to drive the Jag in a similar style that is used with the 60s F1 cars in GPL, keeping it at an angle but always moving forward and not so much sideways.

Happy to accept a power bonus from old installs
But, because I didn't know which of my (Southport) installs was the right one to use for this event
I asked Tony for a fresh link for the D/L and unzipped it onto a fresh GTL install with no other mods

Perhaps an older install conflicted and slowed things?

I doubt it - I think it's clearly a case of you being much better at driving it the way Hristo describes.  I'll try again, but don't think I can get the car to behave like that and still maintain control.

OK, if it was a fresh install then I guess it is unlikely that my theory would hold water.

Just give it a go beyond your comfort zone, Erling. I mean, you have nothing to use in practice, so just experiment with throwing the car around and it will eventually click. Once you take a corner the right way, you'd know what to go for.

TBH at Silverstone DD was quicker than me overall and in practice in particular. It turned out that I was using too short gears and even though it felt like I was going very fast, the lap times didn't reflect it. So sometimes it's down to the setup as well.

Decided to try the Jaguar MK II 3.8 around Silverstone, using my Aintree setup. Had to change the gears one click shorter, but otherwise it felt OK, with perhaps the braking bias a bit too rearward. Managed a 1:46.4 with some small mistakes here and there.

I've uploaded the replay and setup, if you want to have a look and give it a try, Erling:

https://we.tl/t-OVLviMmXWv

Thanks Hristo; I'll take a look and give it a go when I get a chance.  I think your laptime confirms that Matt really is rather bloody fast in this car!!  :)

Just did another 60+ laps of Silverstone with Hristo's setup.  The short version is I just can't do it!   Simply don't posess the driving skills to extract the most from this and similar cars.  Am at loss about what to do with wheels and pedals to achieve the smooth drift required - all I get is either run wide understeer, or, in the rare cases I get the rear to break loose, a speed sapping power slide.  Frequently the car would also oscillate between over- and understeer through a corner.  At no point did I ever reach the speeds visible in Hristo's hotlap - car remains a sluggish barge when I drive it.

Ran without auto clutch. Normally that gets me into trouble, but the Jag is so sluggish it didn't here.  After 30+ laps, I finally knocked 0.4 secs off my earlier pb, with a 1:50.6.  After 40 laps, another measly 0.2 secs, for a 1:50.4.  In various earlier laps I saw sector improvements which, if I could have combined them all, would have given me a total improvement of 1 sec, for a 1:50 lap; still a far cry off the laps of Matt & Hristo.  The two laps in question were merely lucky flukes, rather than aha-moments from doing something decidedly different.

Hristo, puzzled about the very high tyre pressures in your setup - even at the lowest 250 setting, I was unable to get even temps across the tyres with my own setup, the middle always being hottest.  With the higher pressures in yours, the difference is even greater, but I expect there must be a reason for it?

Could it be that you're using the wrong car somehow? There's no way you're 3-4 seconds slower than us, considering we've had close battles on other tracks. Can you upload the replay of your hotlap so I can have a look?

As for the tyre pressures, I had them high for Aintree to achieve better top speed and didn't bother changing them for my trial run here. I've also noticed the middle going higher, but if it's the way you say and lowering pressures doesn't help with that, it's probably better to just keep them slightly higher to go faster on the straights.

Thanks Hristo.  Doubt it's the car - I did try Matt's car earlier and was just as slow with it.

Here's the hotlap:
https://drive.google.com/file/d/1i9AMZQWZLiopG9kehpmnjFt5pp2mDDKF/view?usp=sharing

As you can see, I'm upshifting waay later than you in several places, as I'm simply moving a lot slower.

I watched it. You're not using all of the track width in places, plus you're not carrying enough speed into the corners for some reason. I wonder if it's your FFB settings preventing you from feeling the limit of the car well. You can certainly turn in earlier and carry more speed as you trail brake into corners, and get back on the throttle harder to keep the revs and acceleration higher. It's all about keeping the momentum of the car and not letting the revs drop too much.

Thanks again.  Difficult to say with the FFB settings, without something to compare with.  Going faster into the corners, I simply run wide, so there must be something fundamental I'm doing wrong.  Will try once more, but have to switch to the Goodwood/Cobra combo soon.

Just had another go; a complete fiasco.  Tried turning in earlier, with greater speed, but what happens almost every time, is I hit the apex too soon and thus get the line through the corner all wrong. At Stowe corner and only there for some reason, I would provoke a massive rear slide, at best shedding a ton of speed, but frequently ending up spinning. Have to devote some time to the upcoming race now, so have to put a hold on this for now.  Thanks for your efforts Hristo.

It sounds to me like the issue is mostly that of not trail braking properly and/or turning in the right moment. Perhaps you're lifting off the brake pedal too soon or too much before or during turn in. Difficult to say without being physically present, as you said.

Probably more a question of not trail braking at all !!    This is a technique I never mastered, although with some cars I may do something akin to it, without thinking about it.  Maybe that's where I should direct my efforts; trying to learn this.

Don't worry too much about that car and gaps Erling. I had a lot of problems at Aintree as well. Hristo was 5 (!) seconds faster than me with the same setup and i was unable to find the problem. :)

Maybe not, but it's more a question of whether I'm doing something fundamentally wrong that worries me.
