You can't have the same car from the same production line giving out different power just because one has gone to US and the other to EU. It must just be something to do with advertising rules or the standard measurement and conversion/ rounding up.

For instance the fiesta ST is allowed to be advertised as 200bhp in U.S. but only 180bhp here

Good call.

Overboost is the difference...?

Historically the quoted figures were top end for a blue printed car in any event.

I remember my brother (in Ford sales the last 20 years for my old man ) telling me that you could take 2 Mk2 Escort Turbos straight off the production line and dyno them....neither would make quoted output and both could vary from each other by 10%.

Be nice to think manufacturer specs are more reliable these days......hmmm

In the fiesta ST the over boost is the difference due to it not being continuous power output.

I very much doubt the over boost adds 5bhp on the RS so can't see that being the difference between the two figures, the over boost feature is normally slightly different from car to car I'm sure someone more knowledgeable on the RS over boost will clear that one up

Be nice to think but I doubt it :) probably still vary more than we would like from car to car.

I believe a lot of manufacturers now quote average figures produced from a sample group but someone on here will probably know more than me about it. I know dynos all vary but my last 2 ford turbos produced over the stated power as standard. Although that could be attributed to my running in techniques :yep:

The maximum 324lb ft of torque arrives between 2000 and 4500rpm, Ford announced today, while an overboost feature allows for 15 seconds of full-bore 346lb ft torque under hard acceleration. Although no performance figures have been released thus far, you can expect a mid-to-high four second time during the 0-62mph sprint if the other hyper-hatches with similar performance are anything to go by.
That kind of ties in with the US statement of 350lb torque at 3200rpm... close enough!

I think Dave posted something on this a while back.

What running in techniques were they? Nice and gentle using all gearings for x miles?

More like driven how they should be from the get go.

Not an RS I know but Our first Mini Cooper s was an ex demo car, no doubt thrashed by everyone. It should have been 172 bhp but when dyno'd was it 194bhp. Our next mini was a jcw, brand new I drove it with kid gloves, that was 212 standard and made 211. Our final jcw again was an ex demo car should have been 212 made 227bhp. I'm not saying thrash it from new but It must make a difference.

First 50 miles is most important:

No idling if at all possible (even though the car is moved from transporters etc)

First 10 miles:

Put the car under load and off load up to a mid rpm say 3000. Ideally go through gears using this method and then back down the gears. Try not to keep a constant speed, build revs up quickly to the rpm limit of 3000 then allow the car to naturally decelerate back down, then load up again etc etc. The key is put the engine through the load and unload cycles to seat the piston rings.

10-20 miles:

Procedure as above but increase rpm to 4000

20-50 miles:

Procedure as above but increase to 4500rpm

50-100 miles:

Increase rpm to 5500. At 100 miles do a full oil and filter change. This removes any small metal particles that have built up in the oil from the seating of the rings and stops them from circulating through the engine and scoring the bores etc.

100-1000 miles

keep varying speed as much as possible and include several full RPM runs allowing cooling down period between.

After 1000 miles I normally give it a second oil and filter change and then anything goes. :thumbsup:

A 1.0 ecoboost 140ps produced 144 bhp at 1200 miles using this method

A ST2 FL with 260ps mountune upgrade and cat back exhaust produced 282bhp using this method

(I know dyno's aren't 100% accurate but it gives a good indication)

Id agree with all DS says........ well worth the cost of a little oil on a decent engine.

Worst thing you can possibly do is pick up a new car then sit on the motorway at constant revs for 500 miles :)

There are some amusing threads on the US Focus RS forum from drivers who swear the best way to obtain best power and life from a new engine

is to rev its nuts off literally from driving off the forcourt..ho hummmm.....

If I can find the link I will post it later.
