Took this pic when Mikko's car was in service on Friday. (Hit a wall 7km into stage 1, miss heard the pace notes.... A few other's hit the wall too)... Massive damage requiring re-welding sections of the cage & damaged unibody and strut tower/bucket, brakes & transmission...$125,000 repair finished in 2.5hrs by the M-Sport squad!!!! Watched every second of the repair... It was fascinating.

Anyway, the outside intake is the upper part of the grill, a carbon fiber piece that funnels to the filter.
filter tapers down to the turbo (white thing in there is just a derlin plug to keep dirt out while its off the car)

The opening was no bigger that the mountune intake hose or the cobb stage 1 piping to make WRC power levels.

That's what restrictor racing and race gas can do.

That's a pre-facelift nose, isn't it?

We don't have that piece.

It is interesting that they chose that point for an intake. I would think it would pick up a lot of dirt if you aren't running first and that location isn't usually a very good high pressure area.

Basically posted to illustrate that people dont need to be concerned too much about our intake tubing as its more that adequate for our needs (up to ~350bhp)

2 min gap between starting cars so most dust has settled.

It is a pre facelift nose on the WRC cars. Here's Evans returning to service.

The R5's are running the ST style big mouth grill. (R5 is a "lower" cost WRC car that runs in WRC2... Uses more stock parts, like the stock intake manifold as pictured below)

The WRC cars run a restrictor on the inlet of the turbocharger compressor housing to control maximum horsepower, it use to be 42mm. Basically the turbo runs out of air flow as the engine rpms increase.

Yes. Im well versed in how these engines are built and put together. As I was there WITH m-sport. :thumbsup: These are "behind the scenes" photos

Simply sharing info that others may have been curious about. Even w/ a small turbo upgrade a mountune or cobb style intake will be more than adequate for our HP goals.

This is a great share. Argentina was a great rally too!

That restrictor is far from idea for the turbocharger. The vacuum creates thrust on the compressor wheel, bearing, thrust plate.
By the way, nice pics. Interesting to see how those guys do things.

Pretty much the best pictures I have ever seen of the workings of the WRC Fiesta! I was able to get very close to the GRC cars, but couldn't take pictures of a lot of the stuff. Nothing from the MSport Fiesta, only the Olsberg's MSE cars. Those cars are so far removed from the street cars that nothing is comparable. The WRC RS and R5 are actually closer to real cars.

The MSport R2 intake is something that might work for the ST, especialy after they release the 2014+ intake. It isn't all that different in concept to the WRC one. Plastic airbox with ducting to the front bumper.

Also to note, they REALLY do run Castrol Edge in the gold bottle.

I am going to have to disagree on the theory of "they do this with a restrictor so our intake is fine".

You will notice the smooth bends and gradual cross-section change in the restrictor intake. It was designed very carefully and it still chokes off the race engine in a major way.

Our intake is a lot longer and isn't nearly as well designed. Its not horrible and on a stock engine there isn't a lot of reason to improve things but once people start with big turbos on street cars that will change.
