If PSA somehow ends with 4 R5 cars in their hands, things will get interesting..

When you guys are making theories why this or that about engines maybe I'm wrong, but I think everything makes more sense if one states the dimensions of things...presuming you know them..
I build and have built road car and rally motors..Numbers are everything to me..When speaking of Evo X it might help to know it's bore and stroke (86x86) and what it changed from in the old 4G63 (85x 89) because then, when you read Misterbitchi info it makes sense when they say why the changed it (when obviously it had worked well for almost 15-17 years)..They said "now 86mm bore to allow 1mm larger valves"..
So talking about these WRC 1,6 motors its interesting seeing everybody using 84mm bore versus production 78mm or whatever..More room for bigger valves.
In a 3 way conversation a couple of weeks ago between me and a young clubbie guy in Michigan and a fast Golf guy in Sweden who has an old VW Motorsport kit car we were all reminded that those kit car engines VW used they went UP to 84mm (and destroked to not go over 2000cc) from VWs 82,5mm
Both guys were puzzled---neither being engine guys..
As soon as I said "more room in a 84mm circle for bigger valve" both boys said AHA!!!..
So please, numbers...
With pleasure Jan. Take it easy, I am not sure that the sources I found were all right.
PSA R5 engine (based on 1.6 stock EP6CDT): stock 1598 ccm engine has 77x85,8 but since the cylinder spacing is 84 mm I think the bore can not be larger with competition 1620 ccm R5 engine
Škoda R5 engine (modified stock 1.8): 82,5x75,5
Ford R5 (engine 2016, modified stock 2.0): 85x71,3
Hyundai R5 engine: 83x73,8
From Homologation papers:
PSA engine: 77,016 x 85,9
Fiesta: 85,0 x 71,3
Thanks for confirmation. The PSA block is simply too small for wider pistons.

Just what you guys told us a few days ago from MN Rally.
If this info has been posted somewhere else, sorry for the double post. I read that Lukyanuk crashed heavily (into another rally car strangely) and was injured. He and two others are injured and the co-driver in one of the cars died.
Does anyone know details about it? How can two rally cars crash into each other during a test?
Edit, just found the other thread. Don't know how I missed it to he frank!
Sorry
Like this
PSA 77,016 * 85,9 = 1599,2
Fiesta 85,0 * 71,3 =1617,5
Yes, maximum allowed displacement is 1620 ccm but it wasn't like that at the beginning.
It may sound strange but the reason for such strange figure in the rules is in Renault Clio R3T. Their stock engine has 1618 ccm and they asked for exception before they launched R3T some years back. FIA instead changed general rules for all R3T and R5 cars. Sadly I don't remember in which year they changed it.

Citroën Total Abu Dhabi World Rally Team has changed its line-up for Rally Italia Sardegna (8-11 June), with the arrival of Andreas Mikkelsen/Anders Jaeger in the no.9 Citroën C3 WRC.

Good!
Great news!
Leferbve tottaly out of rally, no change to R5? strange it's FFSA golden boy
With one day of testing I don't think he will be top 3 fast, don't think Citroen has very high hopes either.
Maybe it's more about getting feedback on how C3 compares with Polo and I20.
Want feedback on Crystal Ball 2017 WRC ...
He'll still be better than their frenchman, and he has a really good starting position, & all of that is before you consider he has done the rally last year, & his teammates haven't. If things go his way, we might see him for a little longer in that Citroën.

That's certainly put all the current Citroen drivers on notice. I'm sure we'll see more of him.
Well yeah, Andreas is one of the few who has tried three different WRC2017 cars (Ogier has also tried Polo, Yaris and Fiesta).
I think they want to see where the car is at, is it not competitive or is the problem with the drivers, probably they want to secure at least one good position in Sardinia not to get too behind in the championship score table and get some more setup feedback for the permanent drivers. And it will be a good motivation for Meeke, to finish better than Mikkelsen.
I sure hope so.
I believe Mikkelsen's target should be Breen.If Craig can continue his 5th place run, the Norwegian should be able to better him.
Good news, Mikkelsen deserve this place. In the same time Matton lost his face now reading back his communication before season start about Latvala and Mikkelsen.
So Citroen blinked first...
No surprise given they are last in the Manufacturers championship.
I still doubt Mikkelsen will be instantly fast with being out of 2017 cars and only really used to the Polo.
Finally Some justice in this world !!!

According to @GronholmM, Jari Huttunen got permission from Opel Motorsport to enter @RallyFinland in Fabia R5, but he must use Opel overalls
Matton: "Why I didn't hired him before Monte Carlo.
