And of course I forgot something.
Group R:
R1A: up to 1400 cm3
R1B: over 1400 cm3 and up to 1600 cm3
R2B: over 1400 cm3 and up to 1600 cm3
R2C: over 1600 cm3 and up to 2000 cm3
R3C: over 1600 cm3 and up to 2000 cm3
R3T: up to 1600 cm3 (turbo)
R3D: up to 2000 cm3 (diesel)
R2B:
Skoda Fabia
Also Lada Kalina already have international homologation in group A6/R2B.Quote:

Not homologated yet ;)Quote:

Saw some pics of it as S1600 a while back, did they make a R2 instead ?
Go to post #162 on this thread.Quote:

R2C would have only 5-speed gearbox for example. There are more differences in the rules. In my opinion no-one is interested in such car simply because they have been starting in old FIA classes so far which means that both R2C and R3C would be in same A7 class with certain disadvantage for R2C.
Cup cars..
Or here........ :pQuote:

Today is the day?
YES, the news is in :
"RALLYING
From January 2011 a new Group R4 category will be created. A kit, homologated by the manufacturers of current Group N cars, will be made available for these 2-litre turbo Group N cars to ensure they can remain competitive with the Super 2000 cars.
To increase competition and the spectacle in all FIA Rally Championship events, the WMSC has agreed to the principle of studying technical regulations which may potentially permit GT cars to compete in these events."

The easy solution for GR N is to map them for E85 and that alone maybe match them with S2000.Quote:

I don’t know how you can justify that. The N4 is behind S2000 in performance and by lowering the octane rate for N4 they will be even more behind. Lowering the octane rate means that you have lower the boost to prevent detonation, which means less power.Quote:

A book I have says that MON 85 compares to RON 92. I don’t know if MON 85 is same as E85. To have RON 105, the MON would be 95. But I suppose you know better.
Racing gasoline is RON 102/MON 90. E85 is RON 104/MON 94.
Thanks Mirek. They’re both very close but I’m convinced that the racing fuel has better knock resistance and changing the fuel to E85 wont get the N4 par with S2000.
Is it true that no more S2000 homologations are being given by the FIA?
ie to phase that category out?
No, they continue, only with new 1.6T engine. Otherwise rules are same.
Remember reading somewhere (on this forum or elsewhere) that the super production cars (S2000 with 1.6T engine) wont be allowed next year.
That surprises me. I thought the goal was forbidding more homologations in s2000 to let 1.6T take the place, but with both of car types running together :confused:Quote:

As I said I remember reading it somewhere but I could also have been dreaming. But in 2011 the cars in FIA Super2000 world rally championship must have a <2000 cm3 NA engine. At the moment there’s only one super production car, the Mini.
E85 is called so as its 85% ethanol. Its not to do with the MON or RON rating.Quote:

I thought E85 was already allowed by the FIA? It is used in the New Zealand national championship (which runs to FIA regulations) and is run by several of the top cars here. However its certainly not cheaper to run, as you use about 40% more than pump gas to travel the same distance and it is also more expensive than pump gas typically.
I’ve mixed up things now completely. I don’t know what I was thinking about but somehow I mixed E85 with ordinary 85-octane fuel.
In fact pure ethanol has very high knock resistance and also E85. The additional advantage of E85 is that it have also a cooling effect on the intake air/fuel mixture that’s enables higher compression ratios / higher boost = more power.
Sorry guys for the confusion, especially to you Sulland.
No prob old man ! :p
Alcohol can be used for many things, even rallying !
But will 33mm restrictor and E85 be enough to match S2000 in R4 ?
From what i have saw on various Evo 9 cars, they have more power
with E85 fuel, they use more fuel per km of SS than standard racing fuels and they can`t match top S2000 cars.
Mr. Klaus Schwemmin who mapped Evo 9 of my good friend also told that this fuel is better for engine,
engine has better cooling and combustion with this fuel.
It is also much cheaper, becouse racing fuel is from 3-5 eur/lit, depends of manufacturer of fuel.
This E85 is arround 1 eur/lit.
How much power was gained with the E85 compared to racing fuel?Quote:
