One thing I don't understand.

[Midnight Snacks]

The MOTUL AUTECH GT-R produces 443 BHP and weighs 1130 KG. It has a PP rating of 592.
The WOODONE ADVAN CLARION GT-R produces 493 BHP and weighs 1100 KG. But for some reason it makes 587 PP.
The rest of the Super GT GT-Rs have the same specs as the Woodone but have a PP rating of 595.

This just doesn't make sense to me.

PP is the car's performance point, a car with more HP and less weight doesn't mean it performs better than a car with less HP and more weight.

Also, PP changes easily using different aerodynamic settings.

This.

 

[diptob79]

make sure all cars in default setting, including downforce.

If it still different, might have a look at the max torque

These are all figures from the dealership.

 

[adeadsnipermatt]

I would give them all a spin at the track ad the times will state why they are rated differently.

Wait, a car's actual setup affects its PP? So that a car with a max f/r downforce of 40/60 would have a different PP than if it were lowered to 15/25?

Yes.

 

[Thaddaeus]

Yes.

thanks also for the info!
do you know any thread by chance where the pp system is explained thouroughly ?
im realizing that its not only about hp and weight xDD

I don't understand PP either...

I have the standard "2000" Corvette Z06 with 650hp exactly - it doesn't have full weight reduction but has everything else. PP value is the second highest, topped only by the Bugatti Veyron (which its self isn't fully modded either). No spoiler or anything...

2000 Corevette Z06 - 664 PP

It tops the following:
917hp Premium McLaren SLR with all drivetrain/transmission/suspension/weight reduction. - 660PP
899hp Standard McLaren SLR with all drivetrain/transmission/suspension and some WR. - 652 PP
852hp Premium Corvette ZR1 with most if not all mods. - 627 PP
1,022hp Standard MB SL600 with all mods. - 625 PP
752hp 2004 GTO with all mods except some weight reduction. - 587 PP

List goes on...

Pretty friggin weird??

The whole PP thing is still a bit broken anyway. As an illustration, I have six Formula GTs, almost all of them with 935 horsepower and of course the same in all other ways. Of course the one with 921 HP (or whatever it is now) has a slightly lower PP rating (902, I think), but the others also don't match. Even with the same default setups, only two or three of them have matching 910 PP ratings. One or two of the others with 935 HP and default setup have slightly lower PP ratings. One would think that identical cars with identical specs and identical setups would have identical PP ratings, but they don't.

make sure all cars in default setting, including downforce.

I don't know how much the game factors into PP ratings, but there should be more to it than just horsepower, weight, downforce, and torque. Lots of things, dozens of things, effect a car's overall performance, and not just a handful of specs.

One of the things I liked about Forza Motorsport 3 is that it will give me a list of performance specs that changes with every tiny modification I make. If I tweak the ride height by just a hair or make a tiny modification to spring settings or toe, it will update the whole list of performance figures for me. Also, in GT5 when I buy an upgrade for my car it only shows me how it adjusts one single stat, normally horsepower, and that's it (at least on the screen when you're initially purchasing it). In FM3 it shows me how it effects my stats in general, like how the added weight hurts my braking just a hair. If I add a turbo kit to my car, that changes the weight of my car and changes the weight distribution, which effects my car's performance in various ways, but in GT5 when I go browsing upgrade options if I'm looking at a turbo it only shows how it would change my horsepower rating (and PP).

Yes, you can see it change as you modify the setting. None of the other tuning options (besides engine and ballast settings) will though. Would be interesting if tires affected PP.

This example is not as gaping of a hole as the one I brought up. I mean perhaps PP also takes into account mileage, body damage, engine damage... I would expect at that level of racing these things could easily alter the performance of an F1 car. I know it can't be easy to keep up maintenance on all 6 of them. Anyway, at least they're all within the same ballpark with probably some undiscovered inclusion that effect PP values that make the difference here. Hard to say...


But I mean come on... I don't even think I bought anything "racing" related for my Corvette Z06. I bought it to just cruise around some of my fav tracks and suddenly its the second most threatening road car in my entire garage.

A bit broken is one thing but wow... seems a bit goes a long way in my particular game in comparison to yours.

I've had a premium '04 ZO6 max tuned for a while (full aero and broken in), and it's at 764hp, 692tq, 1172kg and 620 PP. I couldn't believe the PP for your 2000 ZO6, so I built up the one I had in my garage. Performed engine and chassis rebuild, maxed aero, 742hp, 638tq, 1173kg and 621 PP.

Funny that it's higher than the more powerful '04, but not even close to 664...

It was interesting when tire selection changed PP. But, too many people complained and PD changed it.

I like the PP system. It's a good method of handicapping races. Some cars are faster than others...even if both have the same PP. I think that's natural because each car's shape, inherent aerodynamics, weight and balance, and handling are different.
