Thanks Pete   :thumbup1:

My goodness, what a track this is in these cars, love it  :tt1:  8)  Interlagos has always been one of my favoured tracks anyway but I didn't realise how much the modern version is so neutered compared to the old original layout. :o  What the heck were they thinking doing away with all those magic corners  ???  A travesty  :'(

Feels like another new circuit to learn to me, I could blast around this all day  :)

Any chances to have the Lauda's skin in this race and next?  ::) Regazzoni's car has less power....

doh what,  I though this was gonna be bi-weekly  ???

Fab, stop to complain about your 490-495 bhp, our "low money level Ford engines" could start taking offense of that !  ;D

More seriously, I think the problem about your car is she doesn't take advantage of her front end design choice for now but your engine is just fine ; as I understand it, there was a huge design question at the time, to suit the rules of the championship : should the engineers envelop the front wheels with the wing in order to get less air opposition or go through the more modern wing design providing more maximum aerodynamic ? Also comes the drag question of course.
I guess you'll be more comfortable at Monaco, Zandvoort and other tricky tracks when we classic wing users are struggling to find more aero.  :punk:

Nope, due to the pitiful interest i got in running it bi-weekly with ACC  :'(  This side-burned baby burns bright into the New Year  ;D

if I trim my beard into some proper pork chops and 'tache will I go faster ???

I joke of course, after all every driver wants more power from the car.  8)

Yes, I agree with your speech. I think at the time the rules were quite free. If I remember correctly, the small wheels in front were for an aerodynamic choice too. So even having a wraparound front wing could be something to improve the CX. Some cars, like the Hesketh, even had a real additional wing on the nose. The Ferrari (but also other cars) doesn't have a nose like that, but one more "traditional" (more similar to modern ones).
After probably the rules have given very precise limits and we had the front wings as we know today; without forgetting the few years of wingcars often without front wings.
In any case, currently the shape of the front wing is designed to let the air pass over the front wheels, which is why the wing is more voluminous on its sides.
The 312T's front wing is also heavy convex (I noticed this from the pic of Fmg at Suzuka). Checking well on the web, it seems that the wing is always the same even on other tracks. In fast tracks it is set to "0" and seems laminate (like a P51's wing), when it is set for high downforce is quite impressive (as Suzuka).

Returning to Assetto Corsa, of course the cars were balanced to have a good battle between them. This is a right thing.
About powers, my engine is a bit disadvantaged by not being able to push all the RPMs, the maximum power should be at 12500, but the Rev limit. comes first. Instead the DFVs have the Rev limit. enough above the maximum power point, this helps them a little bit.
But I found out (speaking with Fmg too) that the 312T has a ton of "free downforce", which helps a lot.
I'm currently running with front wing to 0.  ::)

Nice vid from Interlagos (yet '76) :
https://www.youtube.com/watch?v=uS7zWGz_Puk

Yes the cars are balanced for sure but not so much I think so..

Unfortunately you can't get those 495 bhp, that's true. But the engine is supposed to have a very nice power curve so that even at 11000RPM you have easy 475 bhp yet.. You can reach 12250ish (full 103%) but only for qualif purpose, still it gives you about 485-490 bhp and in race you might set it to 102% 12150ish and reach chequered flag with about 480 bhp.

I think it's good that cars are bit different, never though that qualified 4th @ Buenos Aires with BRM, instead @Brands that thing didn't go nowhere...can't wait this one.

I won't be around again as I am still working on my new house.
Still annoyed that I have to miss the first couple of rounds of this great series. You guys have fun though!

Priorites Stefan! first thing you should have done is set up the ISP and pc  ;D  Shame you are missing the fun.

I knocked a second off my pb here last night but am still a whopping 1.5 secs off Fabris Ferrari  :o :'(  I'm struggling with understeer almost everywhere so looks like my Buenos Aires setup just doesnt work here. Got a few tweaks in mind to try tonight.

By the way, hope our new guys know we run a practise server throughout the week leading up to a race? With the times reported on Stracker using this link:-
Live Timing: stracker.simracing.org.uk:50041/lapstat (http://stracker.simracing.org.uk:50041/lapstat)

Same here, shame, I was looking forward to Interlagos next week when I can make it. I hope at least there'll be a break over christmas and new year when I'll be away from the wheel...

Sorry Les, bi-weekly would have suited me too if we'd had enough interest with a modern series as well. There are no races for the two weeks over xmas as both xmas day and new years day fall on wednesdays  ;)

Guys i think ill choose Tyrrell P34 for whole season (OMG what im saying!). I love that sexy babe. More wheels = more fun!
I hope ill manage to race tomorrow with you all.

Race day folks  :euro: The car grid should look pretty tasty at this historic track  :)

Yeah, I should think so. Maybe someone could put up a small youtube vid of the action..

Hi everyone,

I'm going to try to make tonight's race in the 2nd Lotus if it's free!
If it's taken then I'll probably skip today's race as I won't have time to practice / set up another car.

See y'all later hopefully :)

Oh by the way, my in-game name is Louis Defor right now. Should I change it to Olius for the race?

PS: Olius is set as my "nickname" but I never see it displayed anywhere in AC. Anybody know what it's for?

Welcome Olius, enjoy the racing.

Welcome Olius, the other Lotus is spare at present so feel free to drive that.  :) Your real or alias name doesnt matter as long as our trusty admin guy Pete knows who it is to apply the result too. (and you just confirmed that).

Thanks Mark.

Reading earlier in the conversation, I agree that understeer is a major problem here.
In the Lotus my setup actually has full front wing and almost no rear wing! (<- moar spead)
I also found that lowering the car helped a lot too.

I'm used to driving 66/67 F1s (with no wings), maybe that explains my strange setup...

Oh and just to be sure, qual is at 20:15 _UK time_ right?

Hey guys,

Are the event times GMT ones ?

Times are UK time, which is currently GMT  :)

So will I be the only one with the reverse solution? Hopefully good.
Wings 0-2 here.

Welcome Louis!

oh boy...

just ran a handful of laps to "learn" the track,  I fear I'm not going to be fast, but hey, at least we have nice scenery today...



*no sandbags*




Looks like it could be a decent size grid too  :)

Of course I speak only for myself, but you should be whipped to death !!  :angel-wings: :clown:

Whishing you a fast recovery, and thank you for usually setting the server up, it's not very sexy task, so you have my consideration be sure.  ;)

I may be the only one happy to hear it's been postponed til next week, that way I'll be able to take part after all.  ;D

Anyway, since Youtube keeps recommending this stuff to me, here's Emerson Fittipaldi driving a V8 round the old Interlagos circuit in 1973...

https://youtu.be/ZG5C2nyEyFo

Whoops, that was embarrassing! Link corrected...  :-[

Anyway, Emerson describes a lap round the old circuit. Might be useful, just that it's in Portuguese of course. Shame, I really need the help with this one

If Pete/whoever can send me whatever files and info are needed I can probably sort the server - I used to do it for UKGPL when I ran one of the series there.
Only problem is that I will have little idea of what time it is in the real world thanks to racing in the Rift...
But at least I'd be able to react once a problem became clear.

Essentially it's access to the remote desktop and then the where with all to edit a couple of ini files.

Everybody gets a copy of the dedicated server, it's in your AC install directory in a folder called server. The ACServerManager.exe creates files for you and includes help but once on the server I find it easier to create the files locally and copy and paste changes to the ini files on the server especially when it's just changing session times/passwords

@pete thanks

@fmg, thanks for server help offer, I was hoping one of you early birds would be able too.

@Les, shame that lap guide is in Portuguese  :'(

Unfortunately I don't understand anything about servers/internet, etc, otherwise I could have helped you.

Nice video of Interlagos '75.

Here Niki Lauda explains his car. Very nice dogled gearbox with protection for the R.
https://www.youtube.com/watch?v=A9829scjYmM
It is in italian, but you all know the Italian language. :)

Any setup advice? From default settings I only changed tires to soft and wings to 0/2 front/rear. I'm so far behind even the next slowest car, that I feel like there is something missing.

I think in Tyrrell you need use more wings, try 5.

i've tried several combo of wings with varying results. The less wing is more edgy and fun to drive and within tenths of my best times but mid-wing appears to be better for more consistent laptimes and also my pb's..so far.  0-2 was undriveable in the Brabham, it wouldn't hold the rear end in any of the corners.
Consistently softening the front end seemed to give the best gains as there was tons of understeer here, losing me time in every corner. Such an opposite setup to I used successfully at Buenos Aires in round 1.

ps stunning laptime by FMG  :o  I still haven't run a lap on the softs!

You only needed to change the scheduled date on the existing event, not create a new one. You also need to edit the date in the calendar by clicking the little red star preceding the entry in the calendar.

I think it's all Ok now.

The initial post now shows the correct date but all subsequent post's have the old date.

Wings as 3/5 (middle settings for both) definitely feels better.
Where do you soften the front? Arb front setting under suspension? Increase the value(help says higher value, faster turn in)?

@Syd - only 3 things you can soften at the front, anti-roll bar, springs and damper (bump). Try knocking the ARB down one notch at a time first, you should notice you can take a tighter line in the corners without the car washing out so much. I'm about 4 notches lower than I was at round1  :o

@Tony, thanks  :)

Hello everybody,
I do not know if I present myself here ...
I'm going to do a little test in F1 with you, not sure to do a lot of races, to see if I'm capable ... In any case, I could not race tomorrow, I already have a race planned

Otherwise, I'll be waiting if you go racing in GT / Proto or other legends (CanAm! ) ...

I am French, I am 58 years old. My first sim was GPLegends (but I have never succeeded !!), a preference for old cars, but anyway, not very fast, no worries! ;D

See you soon

A warm welcome Christian, good to see you have dipped your toes here and had a run on the practise server  :) Always good to see another historics enthusiast here, hope you enjoy racing with our international  group  :thumbup1:

Hello and welcome to you Christian ! 8)

Pleased to see one more classic car enthusiast ! I'm french also by the way.

I just realised I hadn't put any more laps in this event though.  :-[

Thanks !

Ah, cool , je me sens moins seul  :D

Race Day Folks !!

@Pete...hope you are on alert this week  ;)  :detective:

Should be ok for tonight  :-*

good man Pete  :)

i think the variety of aero combinations will be interesting in the race tonight. I dont think i've struggled as much to get a setup right as i have at this track. Every tweak to improve on one part of the track felt like a compromise on another  :-\ My wing settings have gone up and down like a yo-yo  :laugh:

It is a cracking track though for these cars  8)

Yes, very hard to understand the setting up path here also. This track is known for that too, yes ?

What is the ideal process to setup a car, and could aliens give inputs to this ? Here I try to go this path :

1. Rough gearbox length, rough aero
2. Geometry (asap cause it modifies everything else)
3. Tyres pressures (same)
4. Rough dampers/suspension
5. Drive train
6. Brakes/Engine RPM
7. Fine tune gearbox length/gears
8. Fine tune aero
9. Fine tune dampers/suspension.
10. Try hard. :D

In case of BRM this goes more like this...
1. set full aero
2. realize theres no any traction
3. set low aero
4. realize that damn thing still not going fast and traction is totally zero now
5. go back full aero and enjoy race 'till you hit the wall or/and frustration...  ;D

hey, you've stolen my Brabham setup  :laugh:

My qually setup is very different from my race setup here. What works fine over a lap or two was hopeless when brimmed up. I'm still not overly happy with my race setup but it'll have to do. I went for consistency rather than outright pace as i think once the tyres go off, these cars will be a proper handful on low wing.

Salut, Christian. Welcome!

I started with a soft suspension setup, then I move to stiffen and it seems better. Car is quite no-friendly in every case. About aero the Ferrari has a lot of downforce so I'm at minimum wings.

1. Tyre pressures - they won't be right at the end but you need them nearly right for the rest to actually work.

2. rough gearing (this is more like 1.5 as it's generally done while getting the tires right - you're only trying to get the car to hit nearly max revs in 5th at the fastest part of the track at this stage).

3. Aero + Geometry + springs/dampers. These 3 directly affect one another. More aero requires stiffer springs, stiffer springs require more damping, stiffer springs change ride height which changes nearly all geometry....
You'll have to experiment in stages at this point to balance your changes out as you work, so it can take several runs for it to start improving.

4. Diff settings + front/rear ride heiight - these are to suit you and the setup you created, in the 75's I'm finding them critical in controlling the car behaviour at lower speeds when the aero stops working. Ride height can do a good job of helping the car to turn to suit you, the diff can limit or encourage over-rotation for you (when done right).

5. Have another fiddle with aero to see if you can make the car drive better/lap faster.

6. Serious gearing overhaul. Personally I run 1st long enough to be used in the slowest corners on tracks where that is useful (i.e. here). The car should be geared to avoid having to change under power in a corner wherever possible and also never drop below the useful power band (about 7.5/8000 RPM in the DFV stuff) unless you are in 1st.

7. finalise tire pressures.

8. Calculate fuel load for 45 mins + 1.5 laps - apply to setup and save for race. Test to see if the car remains drivable with the extra fuel - often improving the fully loaded car still results in a better car late in the race.

9. Start pretty much from scratch for a qualifying setup because the softs behave so differently  ;D

10. Somehow launch a car with 1st geared to 100Mph or more, then try not to die during the rest of the race.

Event server is up, please shout ASAP if there's something not right.

 >:( Gearbox broke too many missed shifts, bugger.

This race was probably the closest experience to races "old style", when pilots also had to fight with car problems.

I realized that I had problems with the gear stick (I mean the physical one) as soon as I joined in server. I was hoping that the problem was reduced by using the stick, but unfortunately it was not so. Some laps were really terrible.
I had some troubles with the gear stick in the past but I thought I had solved them by removing the "cap". Unfortunately, tonight the problem was big and almost unplayable. I was near to quit.

The race was interesting and I started well, going side by side with FMG during first corners. Then I had a close fight with Mark, Louis and my gear-stick. I finished 3rd.

That reminded me when I had gearbox problems with my motorbike and gears went often off/out. A bordel.  ;D

Congratulations to Tim, Mark and also to Louis (a little unlucky).

I will come back on the race later but I would like to shout 2 sorry to Laurent and Bob :

@ Laurent : We both were very cautious at that end of straightline braking point, I did brake quite early too noticing you had overtaken me in the straightline, but there was plenty of room in front of me outlane so I went in, then I saw you lowering your speed throught the 1 st apex and I surprisingly was passing you in my finish of 1st corner, but as to me those 2 left corners are actually 1 double left I went a tad on my left to catch the 2nd apex, still in a out lane, but unfortunately we had very different trajectories there and my rear left wheel caught your front right  :-[ I'm really sorry but I couldn't even see any part of your car right at this time, you were in my dead view, I only knew you were somewhere in my rear left, but couldn't imagine we were so close because I had spotted you far in the inside so far. A shame then for all the fellows who were caught in the mayhem it caused.

@ Bob : we got several critical moments ! :D You didn't spot me at your rear left once, then when we were side by side at turn 1 you pressed me outside, we contacted, but miraculously kept cars on track. Then that 3-4 cars close fight with Syd in front was outstanding and I noticed that you guys were braking early at Ferradura but the lap after, even if I had noticed it and wanted to be careful I've been surprised again, I was afraid to contact you so did a small emergency left move which led to me getting the kerb, losing control and eventually tapping you. :/

I will do a drive-through @lap 1 next race.  ::)

By the way, could we get that Kyalami download link ?  :laugh:

A pretty woeful race for me. I managed to avoid the first lap chaos, but I had horrendous understeer everywhere, that went into snap oversteer as soon as I managed to get any power down. So there was no way I could defend any of the places I'd made up. And then on the last lap, I washed out wide at the fastest curve just after the start line and so ended up a well deserved last. Not one to remember... Any suggestions where to look for tips on setup?

@ Maxime

Thanks for apologizing. For me that double left is not one corner as I don't have the grip to take it that way, I have to let go off the throttle and point the car in. I imagined it was hard for you to see me.. For me it was a racing incident. Barone did crash into me because of this and my front wing was severely damaged. I was losing a lot of time in the corners because of it. I went a bit wide and went into the barrier a few laps later with suspension damage. That was the end of my race.

Another good result for me, very happy with a 2nd place finish once more  :)  I'll take the points while i can as i keep expecting the usual fast barracudas to switch on the pace  ;D

Qually was excellent, really having to push on the limit the whole time. Everytime i set a fast lap then Fabri would pip me by a 10th of a second! On my final flying lap i set a new pb and thought 'yes, bagged 2nd place' only to see Fabri had done same again and pipped me by a 10th  :taz:

Got a good start in the race and squeezed my nose up between FMG and Fabri heading into T1. The Rift was vital in these situations as i could glance down left and right to see their wing positions and all 3 of us went through side by side without contact  8) It shook out into 3 of us battling for 2nd position with FMG just ahead. My Brabham was up against two powerhouses in the Lotus 72 and the F312  :o  I was jabbing away at Fabris Fezza whilst the Lotus kept assaulting me from the rear and i was sure i would ultimately lose out on pace. Fortunately my low downforce gave me good pace and i kept being able to slipstream the Ferrari up the long s/f straight/hill. After several laps i got by at T1 and could set off after FMG (yeah right) but he already had a 7 second gap over us battling trio.
The two other cars kept me company for a while but eventually slipped about 6+ seconds behind me. I often caught a glimpse of FMG ahead or Fabri in my mirrors at range, but other than that it was a tough solo last 25minutes of hustling an F1 car at high speed around this amazing track. I didnt put a wheel wrong the whole race but had no answer to FMG's pace ahead. 
Finished 2nd drenched in sweat (heavy steering on these cars!) and aching eye-balls from the Rift.  :)

The Rift is epic with these cars, i love just looking over my shoulder at the grid and in combat with other cars.

Not a bad turn out at 11 cars but we are still missing 5 of the guys who said they wanted to race this series  :-\  Be nice to fill up the gaps. Where is Max? thought he'd be challenging FMG and Fabri for wins.

@Les, you need to get yourself on the practise server when other drivers are on, best place to pick up setup tips. Understeer was a killer here and took setup work to iron it out.

Next we head to South Africa...Kyalami  :tt1:

@IbnSolmyr, no problems whatsoever, had sustained damaged in first lap incident( not my doing) and I race with the Rift with nothing else on the screen, and to be honest the mirrors leave a lot to be desired in AC. My specs kept steaming up and had lost a fair bit of speed with the damage to the car so apologies if I seemed a bit erratic. Kept missing gear shifts resulting in gearbox failure with 15 mins to go. Car in garage this week having a new 5 speed automatic gearbox fitted and an L plate and sensors fitted  on rear  ;D ;D ;D

Can drivers who don't have a little flag next to their name in the race results please do this.

Go to Profile/Driver Details and fill in Country.

Thank you  :thumbup1:

Yes, I'm really sorry that your car and Laurent's one did hit that heavily cause of that damn incident. A classic little wheel-to-wheel resulting in many cars damaged and surfing on the grass..  :'(

I had too much to do lately, prolly going to miss the next couple of weeks too...

It's done :P


The March has quite a nasty bug where it sits too low and bottoms out a lot on bumpy tracks - It probably didn't do this much at Buenos Aires as that track is pretty flat. But here at Interlagos I would expect it to be noticeable.
I think the problem isn't so much a bug in the car model as just the shear length of the cars nose - I found it out the hard way at Zandvoort during my testing  ;D

You should hear and feel when the nose bottoms out - this will happen at very high speeds when the aero really starts to work, and also under hard braking either at high speed or into an uphill gradient.
The only sensible fix is to raise the car until it stops - I think I had the car up to 60mm front and rear or possibly more.

I've attached the Zandvoort setup for you to try - drop the 2 files into "your drive letter:\My Documents\Assetto Corsa\setups\f1c75_march\ks_zandvoort" or better yet, into the Interlagos folder so you can compare against your own setup (you'll probably have to adjust the gears).
I recommend using whatever car height I have it set to, I used that setup at Brands with no issues (beyond my own stupidity ;) )

Cheers mate, I'll give it a try. Default ride height definitely seems to be a problem with this car. Not knowing where to start, along with limited time to get any practice in has been holding me back. But I found a useful video explaining how to set up these cars specifically. We'll see wt the next race if it's been helpful. Thanks!

Thanks @FMG, I tried your setup and found it much easier to drive. It's not bottoming out like before and the turn in is much better. I've sorted out the gearing, now just need to work on the overall balance so I can push it a bit harder. Still a few seconds to find on the lap times... The help is much appreciated  :)

No problems. I didn't expect it to 'work' for you, but it should be a decent starting point.
