i thought they didn't have any spares to debut on artic lapland village event after Latvala crashed....
Just wondering are they so busy that they haven't had time to apply basecoat to the cars because they're not white, but "metal grey"... :confused: Or then the basic white has been changed to a silver type paint.

Usually the price is set before sale, otherwise it would be called auction. ;)Quote:

Per-Gunnar Andersson will get his practising for the Fiesta WRCar with the Fiesta S2000 which is used by Henning Solberg in Monte carlo. M-Sport wil adjust the differential and a few other things - so that most resembled to the WRCar Fiesta.
The 300 hp has been pure PR for many years. Even private team WRC's have been dynoed to have over 360 hp. Over 370 hp is a realistic estimate for the latest 2.0 WRC's of Ford and Citroen.Quote:

I've always heard that the WRC cars were limited to 300 hp (don't know whether it's true or not, but as I read on this thread it isn't).
I have a collection of 1/43 rally cars models. One of the C4's I have says in the back of the box a couple of informations. The one about the power of the engine says it has 320 hp.
320 Hp was power of Škoda Octavia Evo II from 2002 ;)
The limiting factor was air flow given by restrictor size. It's not possible to limit actual power figures.
As I recall, it was certainly stated around the time of the banning of the Group B cars from WRC events after 1986 that their Group A 'successors' would have no more than 300bhp at their disposal. I suspect, though, that this was never formally applied. Hopefully someone more knowledgeable than I am will be able to clarify what is an interesting point.
Think they "tape" the whole car with stickers, color and everything..Quote:

Latest Focus WRC 343hp 870Nm torque, Fiesta almost same amount of HP but around 300Nm less torque. PS. very reliable source.Quote:

As far as I know, power (in an engine) can’t be measured directly, only calculated with the formula P = T * angular velocity (correct me if I’m wrong).
Assuming the peak torque (870 Nm) is around 3000 rpm, the power at that stage would be P = 870 Nm * 3000 rpm * 0,0001424 = 372 PS.
Explanations needed.
If the Fiesta has about 300 Nm less torque, that would mean about 570 Nm. This is IMO quite high value for 1600 cc engine with 1,5 bar boost. 570 Nm is what an EVO 9 has with 32 mm restrictor and higher boost.
The peak torque is lower. I don't know about Focus but in Fabia WRC it was around 2700 rpm I think and that was pretty bad engine.
That's why you connect a dynomometer up to either the crankshaft or flywheel (Engine Dyno) or a set of rollers (Chassis Dyno) and read off the figures from a computer.Quote:

343bhp out of a Focus WRC sounds entirely plausible. The RS500 Focus gets 353bhp without the restrictor plates.
The restrictor is 33mm and the boost is restricted to 2,5 bar boost.Quote:

And the data is for latest spec. works car!
There are some Interesting and positive comments from Jari-Matti in this weeks Motoring News regarding the Fiesta WRC, iirc he said that it had more power than the Focus, the centre of gravity felt improved over the Focus, it had fantastic turn in, very agile and on tarmac especially.. a big improvement with the rear of the car (where the focus 'dragged' the rear) and that they now have the extra 6th cog they had been crying out for.
I would be interested to know if his comments on power are based on perception or actual figures, the extra cog itself will improve acceleration a little and maybe they have found some more power from more accurate fuelling via the DI (Direct Injection) but could it be that these 1.6T engines possibly having greater bhp than torque by ratio compared to the old 2.0T means that they now use the full RPM range instead of short shifting and driving to the peak torque figures they used to previously which should in my mind at least would make it feel faster?
Thoughts?
If they manage to climb through revs, is achievable,despite less cc.Quote:

Wait exactly the opposite imhoQuote:

Use your head....you work for an industry and there are some major changes going on... the more people are interested the more money you will get....now would you go around and say to people that the new product will be worse than the one offered for some time, or you would just try and cover things up...
some of you know some stuff...the majority do not know nothing, and just post for the sake of it....and then i am the bad boy and the nuisance in here.
I noticed that both engines of Citroën and Ford are short-stroke design (83x73,9 and 82x75,5 mm). That's exactly opposite to old two litre cars (except Subaru boxer).
cause they have to rev.Quote:

different situations.
Normally aspirated engines is piece of cake to rev even to 9500 rpm whatever bore x stroke they have,even local garages can do it.
in wrc we have restrictor less displacement,and you have to help the engine from design to breath better in high revs.Smaller cc cant make enough gases for turbo in low revs.High revs helped by small stroke.
part of an interview that Malcolm Wilson gave http://www.therallysite.com/
We reckon we will need to build 15-16 World Rally Car versions for what we have planned. So maybe 20-25 of the 1.6-litre cars in all. Drivers have different sorts of programmes. If drivers want to run a World Rally Car for a single event, like PG Andersson in Sweden and Bernardo Sousa for Portugal, we can look at that. But we have set ourselves a limit of running ten cars on an individual WRC rally.
10 Ford drivers are doing more or less a full championship (Latvalla/Hirvonen/Al Qassimi/Ostberg/Kuipers/Block/Solberg/Villagra/Wilson and now Novikov?) which leaves hardly a Fiesta WRCar available for 1-off drivers. PG Anderson in Sweden, Bernardo Sousa in Portugal and Janne Touhino are confirmed. The rest will depend on the scedule of Novikov, Al Qassimi and Wilson. Also Rene Kuipers will not get many changes to drive the Fiesta WRCar. Even if he is the first privateer to buy the Fiesta WRCar, he still has the car to be run by M-Sport ?
Do some one mention the different rear wings on this picture. Some look like a s2000.Quote:

I don't think that it's so easy with naturally aspirated units. Just watch the piston speed, In my opinion 26+ m/s (similar as F1 engines) isn't something what an average garage can cope with, especially with only steel allowed (if it should work for more than few kilometers).Quote:
