Ironi?

Pretty hard within the rules to do much more than the next motor. Very locked down with everything they regulate.

Inte ironi.

If you want a full test of for example drive train, you just put as much power you can to see where things broke. My way of trying to explain why the engine sounded so much more than todays car which I believe is similar to regulations. But not the first testing car which didn´t need to... Förstår du vad jag menar?

They could have used a 2 litre engine with no limitation on turbo. Which made the car having 400+ hp without any difficulties.

or without restrictor at same engine

VW truck at Algarve, it seems that VW will test today and tomorrow in the north of Portugal and Tuesday and Wednesday on south.

[Mintexmemory]

If they test strength of drivetrain etc, don't they just do that on asphalt, as they can put more power on the ground on asphalt?

Shock loading is more acute on gravel

[Kielder]

Sainz & Moya started today a session of four days of testing with the Polo WRC in the south of Portugal.
Rally Legend is coming.

These days nearly every part is designed using CAD--computer aided drafting, and even low entry level commericial CAD/CAM programs have FEA (Finite Element Analysis) baked in... engineering data on materials is accounted for and is long since known---the computers justy make it so even ignoratnes like me can go clicky clack clicky and know before the chips start flying the ultimate strength of components...Things like bearing strength and life have been in the back of everybodys paper katalog since forever so there's a lot of known knowns before you open the chuck in the lathe...
I've been making stuff for jössös like more than 40 years and it ain‘t like it was.
Reagarding Fords like my Sierra thing, I started seeing about 92 and forsure by '93 all sorts of things that were formerly hand machined and maybe welded up things---like say alternator mount that suddenly were made from 100% machined chucks of aluminum--I knew then that the computing power that OEMs had in mainline jobs--where you are going to make 1,000,000 of the same thing (and the investment of computer time, programming time and machine tool time is worth it) had reached short run level...
And even an old dino like me has used this CAD/CAM and FEA capability when designing some suspension junk for em and my friend Kevin "the Chin" Hawkinson (Kevin's family comes from därborta so I explained what his name should be: Håkansson and if he says it HAWKINson it sounds like ''Hakan'' and he does have a prominent chin so maybe ''Hakanson'' is better. But that's not important----we watch a LOT of F+cup härborta i rally världens mesta u-land so everybody who gets really sideways is blessed eller döpt´---with an honorary Finnish smeknamn and Kevin's is ''Kevvi Hoikansainalainenen''. aren't you glad you asked? )

In any case it is torque eller vrid that stresses gears and bearings and diffs etc.
2,0 34mm restrictor motors made plenty of torque....

Shock loading is more acute on gravel

I don't think so. You can never get so much torque on wheels on gravel like You have on dry asphalt startline just from the adhesion. I would say most of the broken driveshafts or diffs come from starts and 1st gear corners on asphalt. Most of the privateers here on asphalt think about these particular situations to be able to finish...

Today morning in Trier

[Kielder]

It is said that Sainz had a little off yesterday. Today the team was repairing the car. Driving Miss Daisy season ended.
