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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Does anyone know why the horsepower figures always seem to loose just a couple either with time or when quoted for US as compared to what's quoted in say a british mag? Is it an emissions thing? For example the Boxster S when it was first introduced was quoted as having 252 horsepower but it became 250 (atleast for the US market). For the GT2 I saw 460 and 462 alot but the US was officially 456 I believe. Not that such a miniscule amount of power makes a difference but what's up with that?

POST 2Original post

Probably something to do with units of measure. It;s like gas. Our 93 RON is like their 98 RON.

POST 3Original post

Difference between SAE and DIN methodologies for determining power output.

POST 4Original post

Correct. That's usually the difference you see in publications. However, I have noticed a lot of misprints myself. DIN HP x 0.986 = SAE HP

POST 5Original post

And I should have clarified: SAE = Society of Automotive Engineers (US) http://www.sae.org/servlets/index DIN = Deustches Institut fuur Normung (German) http://www2.din.de/

POST 6 / ORIGINAL POSTEROriginal post

I would've thought the germans would be more likely to under rate than americans. Intersting, thanks for the info.
