At the moment I don't have a Porsche but I'm very keen to get one. During my search I came across to a 2004 Boxster S with 38,000Km on the clock in very good conditions but after an independent assessment (http://www.acl.lu/fr/Club/Prestations-ACL/Diagnostic-Center) a dyno check showed only 167KW (228CV). Although the acceleration was pretty linear, I’m surprised because that model should have 191KW.

The seller mentioned that this is normal because the Dyno might be inaccurate and there was no fan in front of the car during the test. He also said that many cars don’t really have the advertised KW. To make things even more interesting, a very small leak of oil and water was detected as well.

On the positive side, the independent assessor believes that the car was in the shop floor for a while because the battery was not too strong and the break discs were a bit rusty. He also believed that the car was driven by a gentle person and for that reason the engine KW output is below expectations.
Dear members, I'm desperate for your thoughts. The questions are:
1) What is the real KW or HP for Boxsters S?
2) Could the low KW output be somehow related to the way the previous owner drove the car?
3) Would you still consider this car if that was for you?

Many thanks!
According to the Porsche manual its supposed to put out 185kw at the flywheel which means you will loose approx 15% through the drivetrain and it will be around 157 kw so it's right in line with where it should be. My biggest concern is the oil leak. Where is is leaking from. If it's coming out where the transmission mates to the engine, you could be facing some serious problems. Most likeley the Rear Main Oil Seal (RMS) has a leak but it could also come from the Intermediate Shaft Seal (IMS) which is a more serious problem. They both can be fixed but if you can't do it yourself it will cost you!!! Check out this forum for more information.

So if the price was right or the owner is willing to repair the oil leak(s) properly then go for it mate
Cheers
Harry
