why is my polophony 001 performing badly on the test course?

[gurdas]

on the first couple laps im hitting 400kmph but after that i can hardly get over 360, and the r360 race car is taking over me. how can i keep it at peak speed?

The F1 cars aren't really much cop on the test course, and the hardcore sports cars like the R390 will go faster than them.

That said, you need to make sure you're setting the gears to be very widely spaced, and run with a low final drive ratio, this will improve the theoretical top speed (i.e. engine speed x top gear x final drive = wheel speed).

Also, the 001 comes with a fairly significant rear toe, which aids traction out of corners, but isn't good for the long straights of the test course, so set the rear toe to 0.0.

Finally, you need to set the front/rear downforce to a low as it will go, to reduce aerodynamic drag. It's advisable that you save the 001's default settings before you make these changes.

Also, you want to play this one tactically. If the R390 is faster than you, just sit behind it for the whole race, in its tow. Then, just before the line, power past it.

it's probably your downforce.

 

[Vasco]

Well, the other cars can go faster.

 

[gurdas]

thanks giles ill try that. but its a 15lap test course so do i really need to stay behind it? also i know they take pitstops, but will i loose speed if i have red tires?

 

[ving]

yeah reds will do that to ya :/

lower ya down force and go for the hardest tires, also get rid of any camber you have cause this wears ya tires fast too.....

MTFBWY...A

 

[modik]

hehhe peppah up your escudo to 1881 hp an' slap on the rubbah band... 15 laps of test course is no object afta dat...

Another factor is the diff. I'll explain. But first have you noticed the inside rear tyre wears of faster then the outside tyre. This is because this inside wheel is being dragged and will result in a loss of speed in the turn.

The explanation is the stiff-set diff. Well the cars weight is shift over to the out side on the turn, the outside wheel will have more grip and the inside less grip. Now because the diff is so stiff the in side wheel will be dragged (inside diameter is smaller the outside diameter.)

When the wheel is dragging it creating resistance, resulting in tyre-wear and loss of topspeed.

The solution there for is simply loosen up the diff buy change down the LSD. Int. Accel. and Decl. to very low.

right i finally beat it, but it was only when i kept behind him all the time, when im behind a fast car i go faster

he took two pitstops and i didnt take any so this gave me the chance to take lead.

You go faster behind another car because of a thing called drafting. The lead car is breaking the air for you so you have less resistance on your car. It's a very small pocket of air and when you slip outside the draft zone you will lose speed very quickly.

Close. However, it's nothing to do with wheel diameter on an F1 car. The reason the inside wears more is to do with the diff, but it's because the inside wheel proscribes a tighter circle than the outside wheel. Therefore, if the two wheels are travelling atthe speed required by the outside wheel, the inside wheel is travelling too fast, so you get that wear.

Ooh man, I forgot to insert that example. Thanks for picking that up.

Giles think abut it. If the outside wheel is travelling further then the inside wheel, the inside wheel must be pulled to keep up with the outside wheel as the wheels are spinning at the same speed because of the stiff set diff.

I'm not sure what you mean when you say "the inside wheel must be pulled". This almost implies that you think that the inside wheel is in effect travelling too slowly, when the reverse is true.

hmmmmmm yeah.. true giles......... try this....
get 2 rolls of toilet paper and stick em together using a stick or w/e
then get a slope edge with a curve and try to roll the lil thing you made.. the inside roll will travel slower cuz it has a lesser radius.. however, in a car, the 2 wheels spin @ the same speed, therefore, you actualy experience wheelspin on the inner wheels on test course

and i thought it was the r390 race car??

 

[wazzuuup]

set the downforce as low as possible f/r

camber 0 f/r

toe 0 f/r

widest gear setup possible

lowest limited slip as possible

As far as I know, you can only get race medium tires for F1 cars. The reason why the uneven tire wear occurs is becuase as the car goes around the turn, the wight is all shifted to the outside. With all that extra load on the ouside tires, they wear quicker. Especially the front outside tire, because it has to steer the car and handle the extra load.

Back-off all of your downforce front & rear and raise the car's ride height. This will cause the air to flow under the car to flow easier decreasing more downforce which isn't needed on the Test Course anyways.
