Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
Maybe the 3.4L is just an overall smoother running engine.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm trying to ensure that this 07 S I bought has a 3.4L engine and it is quieter and smoother than my 05S 3.2L . I figure I can be sure it is a 3.4L engine by measuring maximum speed before redline in 2nd gear and comparing it to the baseline for the 987.1 3.4L cars. Obviously if it had any engine other than a 3.4L the values would be different. Thanks in advance for any help

My friend, your car does not have a 2.7 in it. The 3.4 feels smoother than the 2.7 based upon my experience. Less mechanical sound. I have no idea why. Could have been that my 2.7 was a 5 speed. 75mph in 2nd at 7200 rpm. http://www.roadandtrack.com/content...content/download/54880/1542619/version/4/file/RT_2006-Porsche-Cayman-S_data.pdf

Huhh? That would be a function of the final drive gear ratio, not the engine. Do you think the engine has been swapped? Did it come with a "Maintenance Booklet" along with the owner's manual? That should list the engine number.

POST 4Original post

thanks all for the feedback. i bought the 07 CPO'd Boxster S from a dealer. It was a one owner car serviced by them so I'm probably just being silly. The thing is my 05 S 3.2L seemed torquier and louder. i could really feel the engine vibrating through the seats. Maybe the 3.4L is just an overall smoother running engine. It just seemed weird as I would figure I get more of a rumble and shake from the 3.4L

Sorry to go off-topic but that's a cool document, do they have one for the Cayman R?
