S2000+ (r5)

[Abarth]

What has to be strengthened on todays S2000 cars to be able to take on the added power and torque gain from the Low Pressure Turbo ?

[OldF]

I don’t know how much torque the different parts withstand but affected parts are the pistons, cylinder head bolts, connecting rods, crankshaft, gearbox, prop-shaft and drive shafts.

Move to IRC thread please

Move to IRC thread please

Why, this is the new WRCar. As far as I know IRC will continue with S2000 !

If the tech experts here should guess - how would the BHP/NM figures look on a R5 engine, adding a low pressure turbo to the R4 ?

Just to get used to that R class system !

[Mirek]

I think we need more exact knowledge about the technical solution. At least compression ratio of NA S2000 engine is some 12-13:1 which is way too much for a turbo engine...

In this weeks Autosport they have a piece on the new regulations.

As it stands now they seem to get closer to todays WRC than originally planned:
- Hydraulic gears still to be allowed (said to have longer life than mechanical)
- 100 kg heavier than today
- Not a bolt on turbo-kit but have to change the whole engine
- Changing from S2000 to S2000+ has to happen i two hours with 8 mechanics (engine in addition they said)
- No carbon, kevlar or ceramic bearings allowed
- Single-supplier turbo and intercooler
- bolt on aero kit

It is probably more, but this is the main issues.

If this is not approved on the meeting of the World Motorsport Council next month the new regs will be pure S2000 or Gr N from 2010. This since the last chance for the teams to come up with changes on the document was last week.


Are these regs ok, or are they getting to near the current ones, and it is no reason for change ?

What if they are not getting to an agreement and the new WRC will be pure S2000 and Gr N - is that ok ?

PS. I just read this so it might be something I missed or did not get right, so pls correct me if there is a need !

Thank u Sulland for posting this info. It is not clear how much torque these motors will give, but I simply hope things will stay affordable for all teams. I also read something about FIA wanting the rules to be 'useless to go to a motortuner, cause no improvement possible with these sets of rules', anything about that (I hope you understand what I meant)?

So S2000+ Cars dosnt go to have secuential stick gearbox?
They have allowed pads gears, like the last WRC's?
