Or MW lobbying FIA. “Look what we have made. Wouldn’t this be nice for the next WRC formula (because we can build it)”. ;)

“Based on the standard Ford Fiesta R5 which launched earlier this year, the Fiesta R5+ incorporates a modified turbo and air-intake system. The standard 32mm restrictor has also been replaced with a 34mm example which provides the engine with an extra 30hp. Not homologated for FIA championships, the Fiesta R5+ is intended for national series.”
Few videos.

Re: Rally Cars tech stuff
On a Finnish forum a forum member told that his brother has modified a group N Mitsu to the Finnish FIR R 4WD group regulations. With E85 fuel and 34 mm restrictor (otherwise 35 mm). Dyno results with 1,5 bar boost, 375 PS / 720 Nm.

Here in Bulgaria we used to have 2 drivers driving ethanol Mitsus before 2013. They beated all S2000 on regular bases, even our multi-champion Iliev, but some crashes prevented better results.
Re: Rally Cars tech stuff
It sounds quite possible. Some time a go one engineer told me that for gr.N Impreza with 33 mm restrictor a proper E85 set engine meant something like +40 Hp and +60 Nm compared to usual racing petrol one.

Is there any concern about running out of fuel at the end a group of stages since more fuel is required? Also are teams there buying e85 or mixing their own? And if mixing, are using regular petrol from a pump or race fuel?
Re: Rally Cars tech stuff
It was with a car from Belgian championship, I don't know exact regulations for the fuel - if they use their own or how it is. In the national championship I think the risk of running out of fuel isn't that big as the loops aren't that long but anyway he told me the consumption was some 20% higher.

Probably bigger tank goes with the engine pack

Is tank size not regulated? Even with our open rules here, capacity must be no greater than stock.

May be it is, no idea. But in that case stock trunk should be enough to supply E85 cars for longer passes.
