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:
