When trying to get a car under a PP limit...

[Midnight Snacks]

do you prefer to add ballast or limit the power?

 

[freight48]

Limit power. Handling is very important.

 

[xNEVER-ONEx]

Its all relative as according to the system, a single kg added lowers the PP less than a single HP. But it depends on the track. If its a long and fast track, I will add weight, but if its a short and twist track, I will reduce power.

 

[freedomweasel]

I'd say it would depend on too many factors to make a blanket statement. The amount of points you need to drop, the track, and the car could all be taken into account.

If I had to make a general statement though, I'd say I would like my car to be lighter rather than have more power, so I'd use the power limiter. As soon as you say it's a top speed track though, that goes out the window.

Usually limit power. It takes too much focus to try and add ballast and keep the weight dist. right and all that crap. Easier to say "screw it" and cut some power.

Good point, if there was a weight distribution % listed somewhere I'd be more okay slapping ballast on there. As it is I just have to guess and hope I'm not changing the distribution much.

I tried both and limit power was faster.

You can remove some aero as well. Which doesn't matter on tracks like monza.

 

[zero_speed]

i would use the power limiter on "handling" tracks, and weight on the "speed" tracks.

BUT

If your having to reduce more than 10% power, or add a lot of weight I would redue the build. (This will only apply if your having to consistantly bring said car to that PP limit)

 

[asdfg11]

I would tend to do aero and then power. But I always tend to pick a closely matched car to start with so its a non issue to be honest.

 

[t_w_a_h]

A little of both (+ aero tweaks if required). What ratio of each depends on the cars power curve and existing handling capabilities.

If I have to add more than 5kg or limit power by more than ~5% I generally just choose a different car.

Trying to bring a car that is naturally in a class above the ones I want to race into spec via power limiting or ballasting just limits the amounts of cars I use. Equally, in some cases it feels like it still puts the limited car in a position with a substantial enough advantage to make the race dull.

Good point, if there was a weight distribution % listed somewhere I'd be more okay slapping ballast on there. As it is I just have to guess and hope I'm not changing the distribution much.

Surely if you put it in the default middle position the existing the existing weight distribution won't be changed?

Nope. It all depends on the fulcrum point of the existing weight distribution.

If your centre of gravity is dead in the middle then adding more weight to the middle will not change that. However, the vast majority of cars are front or back heavy.

If your centre of gravity is at the rear of the car, and the car is set up to compensate for that, putting the ballast in the middle will move the centre of gravity forwards and the car handling will change as a result.

Wouldn't you be losing power by adding weight anyway? Seems like two wrongs make a... sort of "right but you could also do this! ..." kind of situation.

Limit the power is best imo. If you car needs ballast, I'm sure it would already be there in the first place when you're tuning it in an offline practice mode.

Nice one Rylan. Now I remember why I never pursued science!

Sorry, going to pick your brain now.....thinking out loud for my own simple mind....

Car weighs a total of 1000kg.

600kg is over the front wheel, 400kg is over the rear wheels.

A 60:40 weight distribution?

We add 100kg in the middle....

Total weight is now 1100kg. How do I work out the approximate weight distribution? Or change in weight distribution?

EDIT - OR does weight distribution not change but CofG (hence balance) does? If the latter is true does the GT5 physics system model this (accurately or at all)?

When I have added substantial central weight and driven a familiar car I can feel the extra weight per sé but I'm not sure I can feel the f/r balance itself changing? I'm not James Hunt though so this could most likely be my limited skill/sensitivity.

 

[Sohvakettu]

Power limitter to make your engine behave like a diesel. ;p

 

[Driver321GO]

another questions is, when try to limit the pp, using the stage 3 or stage 2 turbo upgrade? because turbo stage upgrade 2 have always more torque.
Or let the stage 3 installed and reduce the power more then with stage 2 upgrade?

By adding weight your engine power doesn´t reduce, but your laptimes may get slower due to more weight "carried". And higher weight should have an effect on tirewear, too.

I believe the distribution would shift towards the rear of the car, but as a disclaimer I haven't finished my coffee yet.
I haven't fiddled with it enough in GT5 to see how much difference it makes though.
