I think that this is clear to all of us and agreed in previous discussion. We talk about particular aspects of the story because they are at least interesting.

But that was a change of restrictor. Here we speak about a change of turbine wheel diameter (over fins) WITHOUT a change of restrictor ;)

Argentina won't be so muddy, they don't need the "strong clutch" there ;)

If it is muddy, and you get semi-stuck, you need it, Petter said he would have got the car back on the road but clutch broke...

lol as much as you want :D

All I am trying to say is that it could be an advantage that a certain part is stronger and even slightly heavier..

Petter would had burnt the clutch also without mud.When you try to get out from the forest,you slip the clutch,and the friction materials are burnt.Nothing to do with a lighter clutch cover.So your conspiracy failed.Get it why i loled?

I have burned a few, know the consept... but we don't know anything more of the clutch than it was not homologated and slightly heavier..

But in the end it prob is just me having a bit of fun when "the big money team" makes a slip up ;)

Even though you have a wastegate and restrictor doesn't render the rest of the design a coin toss. There's a lot going on below peak pressure ratio and flow, and at any point you want to speed up the turbo as fast as possible. A larger turbine will generate more momentum to the compressor for a given exhaust flow, of course up to an optimal point.
