R1 – R3, R3T and R3D has been clear for a while already.

R3T = 29 mm (20,5 mm if two turbos)
R3D = 32 mm (22,6 mm if two turbos)

Super production = 32 mm / 2,5 bar boost (not yet confirmed anywhere)
WRC = 33 mm / 2,5 bar boost (not yet confirmed anywhere)

The only open issue is R4 but it’s only two weeks ago FIA decided to create R4. Maybe we have more information after the WMSC meeting in December.

R3D, does it must have sequential gearbox?

It can have but doesn’t to have. It’s up to the manufacturer what they’ve decided to homologate.

About half way starts the English section.

R1-R3:

R3T & R3D:

"Article 260 (for Type R3 cars) applies to cars in Groups R3D and R3T with the exception of the Articles mentioned below:"

I hadn’t been reading the GP Week for I while but today I catch up.

In issue 105 (page 46) there’s a story about the 2011 WRC cars rules. By the story it’s decided that the WRC cars restrictor is 33 mm (and 2,5 bar) but the restrictor size for the S2000 1.6 turbo engine has not yet been decided “as experience is being gained as to equivalence between old 2-litre atmospheric and the 1.6-litre turbo units”.

Mirek said (post #107) that the restrictor size would be 31 mm for the S2000. First I considered it as a spelling error but I’m not so sure anymore. How is it Mirek. Was it a spelling mistake or do you know something?

The min weight for both WRC and S2000 will be 1200 kg.

In the short news they say that M-Sport will continue to use a 2-litre NA engine in the S2000 and doesn’t have any current plan to update the car with the 1.6-litre turbo engine.

[Mirek]

I don't know anything for sure. Just heard 31 mm from more sources than 32 mm

[OldF]

Ok, thanks.

If the aim for the S2000 1.6T is somewhere between 280-300 PS with a 31 mm restrictor, the WRC version could have about 315-335 PS with the about 13% (area) bigger restrictor.
