I know that in the past, cars used to get quicker as they were broken in,

so I was wondering if this would happen with the Cayman. I was thinking possibly not with the exceptionally close tolerances P-cars now have, but maybe it will get quicker as it losens up. What do others think about this? Will our CS's be pulling 4.7sec 0-60mph after 10,000 miles, or is this wishful thinking?

I think you'll likely notice a performance increase. I can't say how much, but part of that improvement will be you (in thoroughly learning the car) and part of it will be the machine. I noticed a significant difference in the engine within the first 2000 mi.

No, the car doesn't really get any quicker (not so you'd notice) after 10,000 miles. What does happen is that you get to know the car much better and have more confidence in abusing the 'loud' pedal so it seems to go faster. i.e. you'll now be approaching the published 0-60 figures of 5.1 seconds, depending on your driving skills. As for 0-60mph in 4.7 seconds, you need to buy a 911 for that or spend an extraordinary amount of money modifying the CS to achieve those figures - much better to sell the CS and get a GT3 (it'll probably work out cheaper!). Enjoy the car as it is and drive it as much as possible and it'll seem to get faster. Mine flies!

I'm pretty sure that this topic has been discussed a few times and most owners have reported that they notice more performance and better gas mileage as they break in. http://www.planet-9.com/showthread.php?t=8729&highlight=break http://www.planet-9.com/showthread.php?t=7987&highlight=break+in

If you look at magazine long term cars from the likes of Car&Driver and Road&Track, you will notice that many of their cars are faster to 60 and in the 1/4 than when they were tested new. Since these are fleet cars and the testers don't generally drive them day in, day out, it is not due to them knowing the car. Green cars are slower...and generally get faster with time.

I think K-Mans would disagree. He pulled a 12.595 quarter with his Cayman, and a few mods costing somewhere south of 7K. There were no 0-60 times given, but it would have been better than 4.7.

This is true. For those that decide NOT to do a proper break-in period .... At the test track, the Carrera S posted some awesome acceleration numbers: zero to 60 mph in 3.9 sec. and 12.3 to the quarter (we got a 4.4 and 12.8, respectively, in a previous test). These numbers were so extraordinary that we took the car to MD Automotive in Westminster, California, to measure the Carrera S’s output on the dynamometer. No steroid controversy here, the car came away clean. The only explanation for the difference in acceleration times is that this particular engine had a proper break-in period (it had 5400 miles on the odometer as opposed to the 1200 miles on our previous test car). http://www.roadandtrack.com/article.asp?article_id=1949&section_id=31&page_number=8

A broken in car will certainly loosen up and perform better than a green car - even if it is only a slight improvement in real terms. If you notice with auto mags test drives, they often see better results from their long-term fleet cars as opposed to when they first tested them new.

What I am talking about is what Chris R. and a couple of others mentioned. The improvement I'm talking about is not due to familiarity, but an actual loosening-up that many car mags have found in their long-term fleet cars. The differences can be quite significant as was pointed out with the Carrera S. Since Road and Track clocked the CS from 0-60 in 4.8 seconds, perhaps a time of 4.7sec. is not out of the realm of possibility. Maybe one of the car mags will check the CS again after 10,000 miles to see if it is quicker. Jeez, if it dropped half a second like the Carrera S did, we'd be looking at a 4.3 sec. 0-60. It would be interesting to see if there is a significant difference in 0-60 times between Caymans that were broken in according to the manual and those that weren't. Maybe this is why Porsche does not seem very interested in trying to match other, less expensive cars in acceleration. Perhaps they know that with the fine engineering that goes into the P-car, they will get significantly quicker with a few K's on the odometer .

Ya think?:dance: But you know it wont end the whining Poor me. BMW is faster, Evo is faster, STI is faster WHY THE HELL DOESN'T PORSHE LISTEN TO ME?

I def agree that cars get faster with a little mileage on them. I'm not sure that article meant that the Carrera had been broken in using the manufacturer's instructions...ie don't go above 4k for the first 2k (don't know how to break in a Carrera so I'm using the Croc numbers as an example). It just had an additional 4200 mi since the last time they tested it. By proper break-in period, I interpreted the article to mean the the engine simply had the miles on it to fully break it in. I don't want to turn this into a discussion of break in technique, I just wanted to convey the meaning I pulled from the article...and that is that mileage makes a difference. Anyway, it took my S2000 18k+ to make it's max horse power and I noticed the transmission get even smoother over the time I had it. I got rid of it shortly after that, so I don't know if it would have gotten any better, but I felt as if it had reached it's true potential (it was all stock BTW). I definitely feel the difference in my CS as I'm approaching 3k. It would be nice if we could see some "free" performance gains like the Carrera! I need to take this thing to the track!
