Special/Ultimate Parts

[hyperspeed980]

I'm looking forward to the High Lift Camshaft S and Titanium Conrods but disappointed they don't have an effect on the sound in many cars. You can make a GT3 RS have a very funny 10,000 rpm sound but an NSX will still sound as if it redlined at 7,500 rpm.

Yeah, I've noticed that half the cars in this game don't have a change in sound when you increase their redline. Which sucks, because the ones that do sound truly amazing.

I attempted to get an idea of what a maxed-out NSX-R would actually sound like if PD were consistent with their engine audio. Below I've left a Drive link containing two audio files, one with the stock engine sound, and one digitally pitched up to approximate a maxed-out version of the car, including S parts, which would bring its redline to 11,000 rpm. Obviously it sounds very artificial, but PD could make it sound incredible if they put in the effort.

Highlift camshaft s for suburu brz s 15
The only s part a was able to get yesterday, the day before i manage to pull 5 s parts not my best luck i guess

 

[R3D]

Can confirm that aston Martin db11 have 933 hp with s cams still missing rods and proably Bore up s and stroke up s as it have the standard parts available,

My pulls today is
Rods for Lamborghini aventador lp700
And Shelby gt350 r,
And ultra high rpm turbo for Mazda rx7 spirit

How much power does the Aventador make fully upgraded + rods?

 

[portishead13]

I probably deleted that car when I was deleting the Gr.4/Gr.3/Gr.B cars...

I found 1 more not listed:
Subaru WRX Gr.B Road Car - Titanium Connecting rod

I'm now up to 120 unique parts out of 205 or so.

Have to check will post it in a few hours



First 6 star in long time and its parts so hopefully some good might be saving it for later date

Nice. Got one for the Nissan Z this morning.

 

[Lazy Blazer]

Mostly money so far this morning including 100k and 500k. A few good parts though.

 

[Ande3200]

Lamborghini aventador lp700 Max power with titanium connecting rods and pistons is 869 hp its actully lower than most would expect, but still very quick even in stock form also have weight reduction stage 5 for it,


My pulls today has been better but it still feels a bit dissapointing

Highlift camshaft s
Toyota crown
Honda nsx type r 02 just missing the rods now

But man what is it about titanium connecting rods and pistons it has showed up 11 times today in all of roulette pulls but not even got it once, they just refuse to give me that part, its just insane, the far most rare of exclusive part by miles at least for me, but i guess its just going to be less parts for each day as we have most of them already now until pd adds more, but its going to extreamly difficult to get them once the glitch is patched, its just crazy how bad the odds are in the 4 star roulettes, won’t be worth opening until having at least 5-6 tickets at least in my opinion

Thanks, will update it.

 

[rataplein]

do you guys think we will be able to sell parts? i don't know what to do with them, if deleting everything, saving up the nitros... i'm just overwhelmed by regular stuff, it makes really hard checking which new special parts i got during the day.

 

[hyperspeed980]

More parts.

High Lift Camshaft S, Subaru BRZ '21, 419>448 HP (already had conrods)
Titanium Conrods, Nissan GT-R Safety Car, 972>1021 HP (all four S parts acquired now)
Titanium Conrods, Mazda Atenza, 400>421 HP (the diesel beast that allegedly revs to 7400 rpm... although it doesn't have any power beyond 6000)

 

[LeGeNd-1]

• I believe S replaces the original part if installed, so it's the same end result if it wasn't installed.
• From the game data. Hence I'm not 100% sure of exactly what they do: the stats are named iwheel and iprop.
• They're not obtainable, but there's 6 with data: roughly ~25% extra boost and 500rpm higher peak than the High RPM SCs for those cars.

Thanks for your answers mate If it's not too much to ask, I also want to know what normal parts do to "hidden" car stats (i.e. anything that doesn't change power/weight but has an effect on PP):

• Anti lag - how is throttle response quantified + any effect on fuel consumption?
• Brakes + pads - to confirm there really is no difference between Racing Drilled/Slotted/Carbon + fade isn't simulated?
• Steering angle kit - is the angle increase the same for all cars?
• 4WS system - is it steering in the same direction OR opposite to front wheels OR changes depending on speed?
• Clutch + flywheel - similar benefit to carbon shaft?
• Increase body rigidity - IMO this feels like a super stiff anti roll bar upgrade. Just wondering how they quantify this in the physics files?
• Body deterioration due to mileage - is it just the opposite of above?
• Oil/engine deterioration due to mileage - from experience with grinding Tomahawk/Veneno, this affects HP but doesn't change PP. Also redlining the car seems to speeds up deterioration rate (but not the ultimate HP loss).
• Are there any effects of air/track temp on engine power?
• Does rim size/width/offset really gives more tire surface/wider track and increase grip?
• Does installing rollcage adds more rigidity?

Might be worth compiling all the info on your github site as well, just for easy reference in the future 👍

Good post. Particularly intersted in carbon brakes, as its previously been mentioned they are cr4p or words to thst effect...

Also wide body, does this actually help at all or not, seems to increase pp slightly, and someone recently said it helped car after installing upgraded engine.

She now makes peak power at 6,100 rpm and peak torque at 5,500.


wooo

 

[Ande3200]

Got 3 parts so far this morning

Highlift camshaft s for ferrari enzo finally😊

Titanium connecting rods and pistons
Nissan fairlady z z34

Nice options, but when polyphony is clever, they‘ll ad all that „special parts“ after that glitch (1.17) on the regular tuning store. 😬

Additionally we need more tuning options.

I want to tune e.g. a Lamborghini Huracan from about 600 to 900 horsepowers AND THEN i ad there a twin-turbo system on it like underground racing or other crazy tuners, so that you got here about 2000hp.

Then I want a engine that can blow away more often then a „regular“ tuned one.

That wound be so nice!!

Not sure it pd will add those special parts to the upgrade shop i actully doubt it, but one cool idea would be to keep them exclusive for a few months then when they add new exclusive parts for other cars they could add the the other older exclusive parts to the extreme tab in the upgrade shop, most Ferrari, and Lamborghini has never been able to get turbocharged in gran turismo in their na models,

But we know for a fact that they will keep expand on exclusive parts, i would not be supriced if all cars in the game will have the option for it as we move on we just don’t know what parts they are adding each month,

I hope that they‘ll expand the tuning options more and more.

For example in GT6 you can tune an Audi R8 V10 5.2 to stage 3 (maximum natural aspirated tuning option) and on top you can tune that engine with a high range (twin) turbo kit for even more power. That was a great tuning on GT6!

• "From the game data. Hence I'm not 100% sure of exactly what they do: the stats are named iwheel and iprop."

I'm shooting in the dark here, but "I" written as a capital letter is commonly used in physics for moment of inertia.
https://en.wikipedia.org/wiki/Moment_of_inertia

It would make sense that a lightened prop shaft, or alloy wheels, or a flywheel, would reduce their moments of inertia vs stock parts.

Depending how they've coded the game the units could be in kg.m^2 (basic SI units).
I= (1/2) * m * r^2 , for a simple solid cylinder (a basic flywheel shape)

so a 5 kg flywheel with radius 20cm (0.2m) would have I = 0.5 * 5 * (0.2^2) = 0.1 kg.m2

Can you see the numbers for any of the "iwheel" or "iprop" variables?


From some rev tests, bouncing the engine off the limiter in neutral then lifting off, I find that the lightened clutch & flywheel parts mean the rpm decreases more quickly, which makes sense.

Does anyone know what cars change in sound with new s parts, tried the nsx type r 02 with stroke up s sound meaner with that part

The S cams and titanium conrods are meant to increase the pitch of the engine sound in any car that has them, due to increasing the redline, but sadly only half of the cars in the game actually do this. Some notable ones are the Toyota Crown, Nissan Z Performance, Porsche 991 GT3 RS and Ferrari Enzo.

Do you need both the conrods and highlift camshaft s for best effect, i have the s cams for all cars you mention except for Nissan z perfomence, i tried with Toyota gt86 limited it have both the rods and s cams for it could not hear much difference despite it went from 7000 to 8200 rpm at the redline,

Yeah, just those two parts can raise the redline by almost 1000 RPM. As for the 86/BRZ family, only the 2015 BRZ and 86 GRMN have an audible difference - the rest stay the same no matter the upgrades. Which gets a little disturbing when fully upgraded, where cars with 10k redlines will sound like they're cruising along at 7.5k.

Widebody reduces top speed by a few km/h, but you gain stability due to wider track width. The effect on PP varies depending on the car, on slow/understeery cars the lower top speed is a bigger penalty so it reduces PP. But once you add power most cars benefit from the extra stability and it becomes a PP increase.

Flat floor (aka rear diffuser) is another OP upgrade. Adds front + rear downforce and actually INCREASES top speed by a few km/h. It's great they fixed it because in GT6 it makes your car 20-30 km/h slower on the straights, the benefit from downforce becomes negated completely

Cheers mate, that's good to know.

I can't find 'flat floor' anywhere, can you advise where it's located please. Maybe just certain vehicles, or I've misunderstood?

Rear diffuser.

Do the side skirts do anything performance-wise?

Cheers!

Good question. Same with tyre size, width, offset etc... or are they purely cosmetic??

 

[Ande3200]

One feature i would love in gran turismo would be wider tyres, still no word on patching the roulette glitch, i have strong feeling that pd let this happen on purpose, to give Sony the middlethinger
