Maybe the 350bhp is a maximum depending on the state of tune that is required/allowed.

350 bhp is impossible for R5 and a complete nonsense. Period.

Fully agree!

Is 300 hp and 450nm far off the truth for a Rally2 upgraded car?

No, it's close, real figures are bit higher, but depends on fuel of course.

What kind of different fuels can they be mapped for?

And how much does a race fuel add?
Is e85/flexifuel allowed in Rally2?

Fuel requirements are covered by FIA Appendix J Article 252 Art. 9 on page 6, here:

How much difference in price per liter is there btw the racefuels and pump price of 98 octan?

How much difference in price per liter is there btw the racefuels and pump price of 98 octan?

In here (Portugal), the racefuel cost around 5/6€ per litter. 98 special (ultimate, evologic and so on) goes around 1.70€/l so it's a big difference.

Cannot say for sure, but in our old lancer, the use of 98 oct or race fuel only gave us about 6/7 more bhp and 3% more Nm, however, the engine temperatures were much better with race fuel. We used the Sunoco one that is said to be the better one for that type of cars.
For instance, we tried the ETS for two races, and twice we blown up the turbo on the car, so, even between racing fuels there are differences.
I do believe that for most R5/Rally2 you either use Elf or VP tho.
