F1 2009 cars faster?

they are using slicks, that will help alot.

 

It seems that way, but the previous tests when STR was using their 08 spec car with slicks it was always topping the time sheets wasn't it?

 

At least thats good news. The whole V8 thing just doesn't suit F1.

 

Actually that's not good news: This will prompt yet another regulations change by Mad Max for safety reasons.

One thing is also becoming apparent: The field this year is even closer together than in the past. With 5 teams constantly gunning for the podium. Now THAT is good news.

 

The reason i don't like the V8s, because in addition of the rev limiter, it decreases the chances of overtaking. Then, most corners aren't really challenging either. Eau Rouge and the 130R looks like normal corners..

 

Although there is less downforce,there is KERS.I am not sure though if it was used twice a lap as allowed.

 

Twice a lap refers to the settings of the front wing: 2 changes per lap

KERS is measured in seconds of use. And drivers will use it on the straights for passing and out of turns to accelerate.

 

thanks for the clarification.I thought KERS can only be used as 60kw(80hp) shots twice a lap.

 

Less downforce means less aero drag and higher top speed. Plus the slick tyres will get some of that grip back from the lost downforce in the corners, because of a bigger rubber contact area.

 

Yes, but the extra hp don't come from the engine, but from KERS.

 

750 + 80 = 830hp.

 

LOL

But actually you bring up a good point: I honestly wonder how the real life math works on this. KERS obviously must be driving the drive shafts in some way or is coupled to the gearbox (anybody know more?). So all of a sudden you have an additional engine helping to turn those parts. It can't be a sudden surge of 80 hp or you'll get instant wheel spin I would think. So how is it applied gradually enough to get the effect but before KERS times out? And isn't there some loss due to friction and management of all that extra power? So in the end 750 + 80 might be 800?

I'd really like to see a drawing of the system. Hey Matchett, this would be a good subject for your next RPM. Instead of telling us for the 100th time about the clutch...

I read somewhere that Ferrari's KERS is mounted on top of the engine. Somehow I find that hard to believe given the weight it is. But then again where do you put it else?

Also nobody seems to have picked up that crazy idea about putting the KERS batteries into the front wing.

 

IIRC, the rotor of the electric motor is directly mounted on the shaft on the gearbox side of the clutch. There has to be a nice electronic control behind the motor that manages the amount of power to be released.
If you're doing 20km/h and push the KERS button, of course the wheels would spin if it went from zero to full power without control. However, the problem will imho not occur when you're on a straight with 250km/h trying to overtake, even less with a computer balancing the power output.
Next to my laptop here I have about 600 pages of text and formulas and diagrams about electrical machines - nasty test next monday. If anyone can find out which type of electric motor they use exactly, I'll explain everything about it in more detail than you guys EVER wanted to know



Speaking of power and torque, I have the feeling that some of you might be interested in this thread...

 

This reminds me of an old joke (which is really funny if you ever looked at a Ferrari owner's "manual"): The Italian encyclopedia about elephants has 20 pages. The German version has 1,000 pages and is titled "An introduction".

Good luck on the test!

 

Good luck with the test, is this any help http://www.f1fanatic.co.uk/2007/09/26/kers-technology-revealed/?
