It is broken. He says at one point "I think the PP rating is amalgam of all the stats shown to to the left" and I think hes 100% right. The game see's no way to simulate stability at 150 MPH and thinks the car is ****. As someone previously said in this thread, it doesnt take into account stability at 149 MPH. That clearly means the system on which the car is overall rated is EXPLOITABLE which means its BROKEN. Being able to open a lock with any key makes it a ****** lock. You don't fix it by understanding why it isn't working, You fix it by by replacing the lock. On top of that we ALREADY UNDERSTAND why its doing this as explained in the video, and it clearly needs to be replaced with a better system.

Missing the point completely. PP system is fine except for niche scenario where cars struggle to go over 150mph on a specific track.
Saying the system needs to be replaced is ludicrously over the top, all they need to do is make a small tweak to how the system measures rotation G for cars that can't reach 150mph. Other than that the system is basically fine.

You have literally no idea what PP that car has, it could be over the 350pp limit that you have to help artificially increase the challenge. Or it could just be that the setup has emphasis on good high speed performance (more power but more weight, less aero).

It's broken in that in IRL your BoP doesn't all of a sudden allow you to run more power and less weight if you can't reach certain arbitrary speed. Also note often IRL you don't get to play with gearing in IRL GT4 or GT3 cars...
You notice some nuances when you are adding parts as well. Some parts, often the gearbox, gets your PP to go down, assuming because it moves the top speed and maybe powerband relationship at speed around.

BoP is not PP. There is still a BoP system in the game, please try to separate the two in your mind.
And yeah, some parts reduce the PP rating because the default setup needs adjusting sometimes to get the most out of them. Widebodies or additional rigidity often reduce the PP rating when purchasing them because the default suspension setup is not made with those upgrades in mind. Same with racing tyres to an extent, if you buy them for a road car the PP rating still goes up but there is potential for much bigger gains by adjusting the suspension which by default is setup for much less grippy tyres.

You can add wing and lower downforce and add hp, will simply make you faster than anything else in that class/restriction that's what I did with m3

Anyone who thinks PP system is broken. Do me a favour and take different types of cars, all with the same PP, and see how they compare in time trials.
I have taken a Ferrari F40 raised to race spec, an R32 GTR with max power but on Sport Soft tyres, an RX-Vision GT3, and a Peugeot 205 Turbo Gr.B round multiple tracks now and despite them being very different types of cars, they all get lap times relative to their PP ratings. This is from Nordschleife to Tsukaba.
This one flaw with 150mph max speed cars aside, I really think any discrepancies you'll find are totally within reason.

BOP IRL is the power and weight of the vehicle depending on what track, you're still on about the PP system in GT7 that again is not being used in any IRL race series,
IRL you actually change gearing depending on the track you're racing on so where you get that idea from I have no clue because any race team have a selection of ratios to go into their cars,

Seems to be the same prob as they had with FM4 & musclecars. Easy to fix, just exclude the topspeed from the PP-calculation

GT3/GT4 cars gear ratios are fixed. Actually for that matter, so are F1 cars throughout V6 hybrid era now...
BoP IRL doens't really supposed to change per track. They do adjust them when they see gross differences. They do review them. And the whole point was all the GT3/GT4 cars running under the same umbrella, say SRO, will run to the same BoP, and that would be across a huge range of track. BoP also limits max wing angle, max(sometimes min)gurney size, mainplane height, etc. So large discrepancy to top speed etc should not exist

Gear ratios are not fixed IRL for GT3/GT4 come on where in the regulations does it say that, how is that implemented in real life with the variety of tracks and running into rev limiters down straights then,
Check page 30 here BOP is adjusted track dependent

The aero is funny to me. I can increase or decrease both front or rear and the pp change can be massive. I decreased drag on the rear by much less than half and my pp went up about 10 points. A bit excessive imho since I'm on a track that's twisty so you would need more downforce which I can see PP going up if I "increased" downforce, but I decreased it by a lot. So why would my PP go up? I can see if I was on Special Stage X where you want to "decrease" your drag for higher top speed. I like that they have all these technical aspects but maybe I'm missing the intelligence to figure out their intelligence lol.

Aero on rear is about stability, not so much the speed you can go around corners (that's helped by front aero). In fact if you have too much downforce on the rear you can actually end up with a car that understeers in higher speed corners.
Also decreasing aero by 50% is a pretty significant change.

Yeah, in the Gr. 3 race at Daytona if you set the final gear top speed to like 154mph it will give you approx 690PP in the RX Vision but if you move it one single click higher it shoots the PP up to 739+, without touching anything else.
It's insanely broken and has been since launch

I don't complain, I'm just stating it's broken in terms that tuning should not affect your car level and the fact that it should be off in online races altogether, simply because many just want to jump in and just race instead of half an hour tuning for each car, besides there is no live tuning like in Forza, you have quit go to menu restart

how is it broken if its increased the performance of the car and hence the PP?

Because there is a huge chasm between the last gear being set to 154 and 154.5 or whatever one single click would be.
I mean gear 6, not final gear ratio. Every other gear's number remains the same aside from gear 5/6/7 (whatever the top gear is) and moving said gear one click taller adds as much PP as putting the high RPM turbo on. That's pretty broken...
It doesn't need to be thrown out, they just need to revist it and figure out why it's doing these things. I much prefer PP to BoP so I'm not saying I want it gone by any means
Edit: It should be going from 690 to 690.5 or 691, not 739. It doesn't scale linearly, and if it does it scale at certain thresholds. It's very apparent when only playing with one setting at a time, like transmission (which seems to be the worst culprit I've found and I've been testing these things since launch)

More than 1 set, but for FIA purpose they are only homologate to 1 set of ratios. For IMSA because of the street courses and Daytona they have other specific ratios that allows for those bogey. But there are no adjustments within the homologated sets are allowed.
FWIW I think PP's broken-ness is less to do with maybe racing balance aside from the fact that everyone basically has to do the same thing if that is the fast way to go, it really has more to be the methodology of how its created. We don't know what kind of tracks or something the PP is evaluated against, we know that it probably has a weighting on how fast the track is hence the emphasis put on a car being able to get to some speed. I don't remember if it was like that in GT Sport but then I think tuning is way less complicated in GT Sport. I think this is more of an unintended consequence of evaluating PP against more variable and creating specific tuning path to go down. From a realism standpoint if the rules allows it people will run it like that. But thats why they try to homologate all GT3 cars in a window they stick with

Yes, but you can only use any 2 of them for anything not Daytona, and you have to use Daytona for Daytona...

The fact that they haven't even acknowledged this as a problem to be fixed in the future boggles my mind, how the hell is it not top of the list!? It's absolutely ruining any PP regulated race.
Unless of course this is because the new PP system is basically a bunch of spaghetti code and altering any singular part of it causes it to go completely tits up.
Either way, sheer incompetence.

Go to the Daytona Gr 3 730pp race in the RX-Vision. Using the racing adjustable transmission set the top speed to 240.
Then go into "manual adjustment" and set 6th to 2.082. This gives 696.88PP on my car, with the LSD set to 5/5/20, downforce at 400/550, no turbo/ballast/power restriction. Move that 6th gear to 2.081 and the PP jumps up to 738.32.
That is what people are meaning when they say the PP system is broken.

Yes exactly! And every other gear ratio change only effects the PP by a maximum of 1 in either direction. It's nothing to do with changing the actual performance of your car, and everything to do with a game bug.
