Technical Regulations for 2009-2015

[pgj]

What are Renault doing? First they wanted the engine freeze, now a standard KERS and now even more standard parts?

My dream 2011 regulations:

-Fuel limit
-no engine config/size limit
-Unlimited KERS/HERS
-2009 downforce regulations but slightly more free to advancement
-Reduction in minimum weight to 550kg

That'll do me

Sounds good to me! The only thing that I would add is no refuelling.

[woohoo]

Thanks for them, mario!

One thing I wish they had re-thought was the size of the rear-wing endplates as they are far too big

Yeah, and the only reason they are so big, is to have advertising space. Same for the air box cover...
Just another example of too much money hurting the sport.

A recent article in AMus tells us during recent wind tunnel tests of 09 aeros, the cars suffered an incredibly small 5% of downforce loss at two car length and even more incredible, the balance stayed the same.

Even if next year situation will be a bit worst that's very encouraging.

If that is true then the rule makers have done a good job this time, hopefully this will be a start of something good.

5% downforce drop at 2 car lengths yet a drop of less than 30% of total downforce? Bravo OWG! =D>

[WhiteBlue]

I expect the 2009 package to be more overtaking friendly. The critical issue in my mind is the apparent violation of the FIA downforce target of 50%. If lap times prove to be excessive with slicks we could be in for some unpleasant consequences on the tyre side. The slicks can be banned and they could go back to the grooved tyres on safety grounds. So I hope that the lap times will come out acceptable. The OWG is playing a dangerous game with this toungue in the cheek downforce levels.

[Scotracer]

I don't believe the FIA would reintroduce the grooved tyres as they would ruin the spectacle. With the slick tyres you will have slightly higher cornering speeds (mainly in low-speed corners) so speeds on straights wont increase much. But, the FIA has been known to defy logic on many occasions.

They could always just mandate that Bridgestone provide a harder compound for the tyre.

that would certainly make more sense.

I read that BMW and Renault are lobbying for 1.5 L / 1.5 bar Turbos for 2012. This would certainly be an advantage for the two engine makers who took many titles with 4 bar and 2.5 bar blown 1.5L turbo engines in the 80ties. I would be surprised if the others letg them get away with that. Also the question is for petrol or bio diesel with turbos. With petrol the RPM could be much higher.

The spet 2008 issue of Racecar engineering (which is still aviable as digital issues by the way) features like all other mags an article on 2009 regs, still RCE manages to dodge to doubtful CAD drawing of what the car will look like and definitely has a more professional take on it with excerpts from James Key and Pascal Vasselon on the 2009 regs.
I'll sum up a bit of info as the two mostly agree with each other:

-Downforce levels won't be 50% but the regulations are done so that the re-gained downforce levels will peak sooner than now (that is, the grow will stop sooner to keep it in good shape).

-Drag is still under discussion but at max would be similar to now.

-Lap times are still a question but both think that by march 2009 they would be at worst a little slower than now but won't certainly stay this way and both would not be surprised to have faster lap times as season goes on.

-Key said that mechanically and "architecturally" the cars would be similar but that there's a lot to play with concerning wings and diffuser.

-It was even noticied that the wing depth for the two highest elements of rear wings can be higher than now.


All in one they are optimistic on the subject.

The RCE is worth the buy IMHO as the treatment is serious.

Reading the autosport article, the cover of which was posted previously. It appears they've missed a lot of the points raised in this article.

[mx_tifoso]

When the teams/FIA talk about DF/drag levels and speeds are they referring to the beginning of the season? When the cars are at very early levels of the seasons overall design.

It would seem as so to me, but I want an outside opinion. Thank you in advance.

I just want to go back to the diffuser discussion from earlier:

Scarbs said:

Yes, but you are losing the taller\longer centre tunnel, this at 30cm wide x 80cm long x 40cm high, is a significant loss in all dimensions.

My reading is that rules 3.10.5 and 3.10.6 allow a smaller central section of 150mm instead of 300mm

3.10.6 says: No part of the car less than 75mm from the car centre line and more than 350mm behind the rear wheel centre line may be more than 400mm above the reference plane.

This doesn't conflict with 3.12.7 No bodywork which is visible from beneath the car and which lies between the rear wheel centre line and a point 350mm rearward of it may be more than 175mm above the reference plane.

Overall volume is smaller and net downforce probably won't alter that much. Anyone disagree?

[Ogami musashi]

I think you're right. At a first glance i see nothing that prevents 75mm from CCL and 350-500mm behind the RWCL to raise a diffuser exit to 400mm above RP.

This post from whiteblue reminds me to say that according to motorsport total the proposal of homologating chassis for 3 years is very unlikely to happen as there are strong oppositions to that.....Thanks god.

Basically we head towards a wise move from FIA..with no time to even finalize constitution of FOTA let alone propose something, then the 2011 rules will be again writtent by the FIA...except if FOTA manages to do something.

7th october...in one month time that's not a lot.


God (whoever/whatever your are) save us from the spec series!
