There is a range in which the engine output must fall to leave the factory. I have seen plus/minus 3% (about 10 hp, a lot) but maybe another can verify this. Also, some say they check every engine, some say not. At any rate the article is a comparison and is on their website under roadtests. I'd post a link for you but I suck at the internets.

Dynoed at 2,100 miles at 407 horses with it 87 degrees outside and 78% humidty...
997S with X-51 engine package - I was told that as the engine breaks in more it might even improve some (as would if it were a cooler day or less humid)...

I believe the 3.9 was for the C2S and they called out having to abuse the car with massive wheel hop to get the great 0-60 time. That is outrageously fast for 355 HP.
The C4S article was the one they mentioned not having any wheel hop -- but the 0-60 times were not as good.

R&T, 3/05 said of Carrera S Coupe "The rear...tires hook up immediately at launch (none of that axle tramp that beseiged past 911's)" Read comparo at www.roadand track.com. It is there for all to see! Others tests have cited wheel hop which is why I have suggested that launch conditions were favorable here for whatever reason.

Each engine is assembled for the that particular ordered car, across the model range, Boxster, Cayman, 997, Cayenne, and when they were in production CGT.
The last stage of the engine assemnly line is a visit to the dyno for every engine assembled. This is to assure that each engine meets its minimum advertised HP ratings.
Also interesting is smewhere at PAG is a dossier for each car assembled that contains the dyno results, as well as all other assembly details.

Interesting stuff Meaker. Haven't seen it before. Now the car I wished I had bought is the standard Carrera that Car and Driver tested in 04. Look at the money I could have saved 
The only thing I have read on the x51 was the Excellence article earlier this year where they found: It (x51) pulled away from CS slowly but surely in 3rd and 4th gears. They felt sound was biggest selling feature.

I don't think the published figures mean anything at all. In your own car, you will probably turn 5.0-5.2, even if your car was that car. None of us will brutalize the driveline just to get a few more tenths off a theoretical clock. 5-100 is more meaningful. AS

While not an absolute, the 0-60 or 0-100 times are a basis of comparison between automobiles. If under controlled circumstances car X does a 4.8 and car Y does a 4.5 we can probably say the second car is faster. What I do on the street in that car is a different issue. I have yet (2600miles) to drop the clutch with revs up. Without practice you cannot be fast. Btw, can I borrow your car for a few days while mine is in the shop?
