Highest Speed in GP4: what is the top speed?

I'm just curious. Today "practicing" in Autodromo Enzo e Dino Ferrari with the Canam mod (a great beta by Meteoro405 :) ) I wanted a Ferrari to do it, the Canam Ferrari got amazing 386-7 Km/h! I tested the Porsche and the Mclaren and they did it too! I had never reached this speed in GP4, it was amazing! I set up the camera to a very good perspective I almost had the sensation of being there, making the turns above 350 km/h :)
I know it depends on the track I don't exactly know how, and the mod regulation of course. Could we get this speed in other tracks or mods? In the IMSA imported by Karl - Huskyman49 - in Le Mans and in historic Imola I got around 360, 350 with the Indycar 2020 (Rracunis) ...

Tks Ariel! Poor me :) Let's take a look at it right now...

in Brasil we say "voando baixo" :)

Whoa!!! Nothing like "flying low" (voando baixo) - If you put wings in it it flies away :)

I see that you could regulate the car so that it goes faster but if you don't, just for curiosity, in this particular case of Autodromo Dino e Enzo Ferrari, with no adjustments at all AND no advanced controls, only the keyboard, rookie mode, those are already pretty amazing results, remembering not necessarily the fastest car in speed gives the fastest lap... :) I was very glad to experiment that...

360 km/h F1 2020
387 km/h Can-Am
378 km/h IMSA 2019
358 km/h IndyCar 2020

all of them give quite a lap, "voando baixo"... :)

Check if the speed increases with Gp4exe = 995bhp , Boost performance and F1 physics = 610kg in the 2020 Indycar MOD

Tks, Rracunis! I did it, the speed was already at the top, as the installation setup, no adjustments, however, IndyCar 2020 mod had the best lap :) in those conditions described above, despite reaching "only" 358 km/h :)
due to a very well balanced car, given it was with the installlation standards, we can really attack the turns and it made really strong laps, we can feel it, very steady...

Hi Guys, Id like to adjust the top speed of some mods. What are the parameters in physics you suggest to change to do that?

Question to physics experts!!! :-)

What mod of yours is this, Meteoro? That GT-One looks incredible
Vc desabilita o F1 nas retas e o habilita antes das curvas?

Hi Rracunis,

Could you give instructions on how to make these changes?
I don't know if they are talking about the same topic, but I would like to make the speeds of MODs closer to reality.
Max 320km/h.
In any CSM or non-CSM MOD downloaded, it's not even close to that.

Thanks

Can you please give me a performance file where all AI drivers reach this top speed at the same time? ;) (Y)

Hi guys after some tests on GP4 1980 MOD I arrived to some conclusions:

The most sensitive parameter that increases very fast the top speed is Downforce/Drag Ratio.
I just increase it from 2.5 to 3 and gain 30km/h on top speed of all cars.

I also discovered that decrease the Mass from 600 to 500 reduces the AI race start difference to human cars ( don't know why ).
Some circuits as we already know the AI cars are much slower than human cars on race start. Changing this parameter makes this difference lower and gives more realistic simulation on race start.

Have fun!!!

Best

Jose

Bo tarde José,
Poderia ensinar como faz essas modificações?

Hi Sidney

You just need to edit physics with the physics editor ( easiest way ) from fongu blog.

GP4 Physics Editor by Aubrey Windle

[fongugp4.blogspot.com]

execute the mod gpxpatch and take a look in the gpxset folder the physics file being used by the mod.

after you know the "physics.g3p" file used ( usually stored at gpxpdata directory inside gp4 ) open it with the gp4 physics editor and change the parameters I mentioned in the previous post.

The new mods ( 2021 ... 2022 ) don't use a physics.g3p file.

To edit physics on this mods you need to use the new Physics Editor from Carl ( more complete ) but I'm still studying it so I will not teach how to use at this moment :-)

best

Jose
