Simulating the 2014 season - Some thoughts

Thanks Tom & Mäth.

My Grand Prix 4 Files
I'm a total dick. How many people can say that?

Hi ... I returned to ms excel and calculations

after some tests I got a power torque curve which is not exactly equal to what the experts think, I believe it should be very similar.

767BHP @ 14702RPM's (273lb-ft)



I'll wait for the next test in Bahrain to see how the current situation will turn out to see if I'm on the right track. everything leads to believe so ... then yes I believe it will be possible to gather data and compile a targeting performance tests.

I think it is underpowered, try it in-game and see. I think the power needs to be 855 at 15000rpm.

Lets try both versions guys.

Tom i tried your physics and their good. I was lapping between 1m22.8 and 1m23.4 with 10lts of fuel starting from
garages in free practice.

entire calculation considered the limit imposed this year by regulation (100Kg of fuel per race). thus, an engine to 10500RPM's should be in maximum power and torque decreasing after ...
this is the current proposal (F1) and it was my goal to play (limited to 15000RPM's). unfortunately for us the grand prix 4 does not give the possibility to aggregate an energy recovery system (ERS) to complement.
the more I believe that to deliver much power in classification, certain engines will have problems with overconsumption in races ... in the past was the lotus - renault (Ayrton Senna). many will not be able to get to the end if they are at 15000RPM's

Jorge - that's a good lap time. What lap times are the AI setting (on Ace mode)?

For me, I am able to set a 1:23.8 in a McLaren using the default setup. The best AI on Ace mode is setting 1:23.4 in Friday practise (Nico Rosberg).

I've made a new Magic Data file for Jerez. I'm experimenting with some things like fixed gear ratios (so top gear is very long) and lower fuel consumption. I might need to reduce tyre wear, I'm not sure yet. Try this:

Special audio by Mario Torrado (aka mustruendor) who made a simulation/prediction of a potential pole lap in Monza this year. I think we match pretty well, apart from della Roggia. So I can confirm that we're on the right way with those physics

That is awesome! I love the bouncing-over-the-kerbs effect coming out of the della Roggia, made me laugh!

Yes, Ace level, i always drive like this. The best AI did 1m24.0. I checked because i saved the file.

I used the red bull to do the 9 laps what i said above.
Later today ill add the magic data and try again with the same fuel.
After that ill do a hotlap and push the car to the limit.

I made some changes to the sound I posted on previous page. I made pitch lower (V8 -> V6, so 75%) so it matches V6s instead of V8s. Please tell me what you think. I'm so looking forward to hearing those cars from onboard perspective next month





P.S. I'll make the new files available tomorrow, it's late and I need to go to bed early tonight lol. Goodnight guys !

I finally chose to make direct adaptations of my 2013 V8 sounds. They don't sound bad at all So you can forget about the sounds in the video I posted above, but all three engine power unit suppliers are done

How I proceeded :

1- I had a good read on [formula1guitar.blogspot.ca] about the differences on guitar settings between V8 and V6.
2- So I understood that I would need to change the pitch of all my existing V8 files in order to get correct sounds.
3- I made some calculations that led me to a 5/9 pitch ratio (15,000 / 18,000 RPM, 6 / 8 cylinders, 1.6/1.8 L [1.8 being the theorical displacement of a V6 based on 300 cc cylinders]).
4- I did fix the pitch of all sound files.
4- And I fixed all the values in my engine.txt files with a 5/6 ratio based on the RPM difference between 2013 and 2014.

Download (all in one) : [www.mediafire.com]

Am I the only one here who thinks the Ferrari sounds a lot like Indycars ? Does it mean I did my job right ?




:// Edit on Saturday morning : I'll take some time to test fixed gear ratios, which will be split into two kinds of setups (1-7 and 2-8). I'll keep you posted on that



Edited 2 time(s). Last edit at 02/15/2014 03:56PM by Briere.

So I made some quick tests with those gear ratio values : 20, 27, 32, 38, 44, 51, 57, 64. Melbourne, Sepang and Monaco ran great with the first seven gears. I'll have a go at faster tracks tomorrow with gears 2 to 8.

Oh and here is a video from Monaco

We now have a very good real life reference video, courtesy of Mercedes. I'm trying to make that sound too, progress is excellent so far !

[www.f1fanatic.co.uk]

this video is not a promotional presentation? these events usually have limited performance / speed in engines (and tires ditto)

PS: no more, I managed to reach the planned goal when I started. hope I'm not being too cryptic hahaha

Im too with Celso on this. Lets be patient and actually watch videos if possible of the bahrain test.
or if we have to wait for melbourne its even better because then we would really see 100% how they
are racing.

Hy!

I've found this good turbo sound. Can you use this for GP4?
video: [www.youtube.com]

New information:
According to an motorsport.com article, Nicki Lauda said that the Mercedes fuel engine produces about 580 bhp. With the additional 160 bhp of the electrical components, the complete Power Unit produces about 740 bhp.

I guess that means we need a power-torque curve with following characteristics:

[*] quick rise of the curve at low revs ( "electrical torque" )
[*] max torque at 10500 U/min, almost flat to 15000 U/min
[*] power of about 740 bhp at max revs of 15000 U/min
[*] for compatibility with other GP4 tools (physics editor), we should have the max power (855 bhp?) at 16600 U/min as the original game

I have the performance files for the preseason testing done, but i won't publish anything before we have an accurate V6T.ini/V6T.cap, because the bhp at 15000 U/min of the power-torque curve must match the "actual race power" at max RPM of the physics and the race/quali power of the performance files, otherwise you have an over-performing player or AI!

Well, i know how to make a V6T.ini but i don't know how to make a V6T.cap! Can somebody explain to me the way to do it, or at least convert it for me?

---

My personal GP4 files at : www.4shared.com ______ My Blog at : Gitanes GP4 work

* Performance Files * LoadingScreens GoogleMaps * GP4 Tracks and Cars Databases

gitanes - The torque values need to be 855.7bhp at 15000rpm. You control the cars' horsepower only in the performance file. See this post.

If you lower the bhp in both the torque values and the performance file, you double-count the bhp reduction and get very underpowered cars.

So the torque values should follow a realistic curve (as per your points 1 & 2) and max out at 855.7bhp at 15000. This is what I've done in my V6Turbo.cap and it seems to work as intended.

About your point 4, it doesn't really matter. After 15000 or so you put whatever torque values you want, the game won't use it.

Also we should be wary of the figures being given out by the teams. In this article a different Mercedes person says their petrol engine produces 690bhp! Slightly different to Mr. Lauda's figure and they're in the same team!

=====================================================

I'd suggest you go for what Niki Lauda said. He mentioned that figure in a talk at a TV show where also Helmut Marko was present. When Lauda started to explain the way the engine works saying that the combustion unit on its own produces around 580 bhp Marko interrupted saying "That's an interesting figure! We'd be happy about having 580 bhp." In contrast. in that artice you refer to the interviewer asks Andy Cowell for a comparison. He says that given the fact the old turbos from 30 years ago had 1,5 litres, a pressure of 5 bar and a fuel flow rate of 200kg per hour while producing around 1400 bhp it would be valid to simply assume that half that fuel flow rate also means the current engines produce around half that power (combustion unit only). All that Andy Cowell replies is "Correct, that's a way to calculate it."

So I'd say Cowell just didn't want to get too specific about it while Lauda and Marko had a pretty honest talk all along.

best regards
chris

Yep that's probably a good conclusion Chris.

Melbourne will give us a better idea, we can change the performance files based on the times they manage in qualy / race trim there. I think we're in the right ballpark with mid / high 700's.
