There have been numerous posts on several threads about the
phantom 30 horsepower
that Porsche has aledgedly de-tuned from the Cayman S engine. So far as I know, the only semi-authoritative source for this is the recent <u>Road and Track</u> article, which rather obliqely speculated that the engine's displacement and maturity should have produced more. Does anyone have something firm that we can pin our hopes on? I am getting all heated thinking that there may be an easy 10% hp upgrade with just a chip change.

If you take a look at the RUF 3400S (A boxster with a 1st generation Carrera 996 3.4L engine swap), you'll see that it had 310hp! The original Carrera 3.4L engine had300hp and 258lb-ft torque before RUF tuned it up a bit. Here's a link:

So here's the Cayman's spec's:

<pre>I still think the RUF 3400 is the TUNED version of this engine..</pre>
<pre>. but seeing that the Cayman's engine still produces less than the old Carrera
its easy to see that porsche intentionally did this. Perhaps there's a planned
horsepower increase for the whole model line in 2008-2009? Carrera S up to 381 hp, Carrera to
355hp, Cayman S to 310hp, Cayman to 295hp</pre>

. . . was that also the same mag article/company whichreported that the US cars bucked the system for the 1st time with the Porsche entire range and has a better exhaust note than the Euro spec car? Yeh right, don't believe everything you read!
Dean
Uber,
What about Unichip? 5 to 9% more HP.
http://www.unichip.us/
While Porsche may have detuned the car it is programming, I find it hard to believe that they killed 30hp from retarded ignition timing. There probably are also intake and exhaust restrictions, a milder cam, and maybe either smaller or less well finished ports.
The question is way the torque curve has such a sharp drop off after 6000 rpm. If you could maintain 250lbf-ft of torque to 7000 rpm you would have 330hp.
Could they have held back in order to have a 2007 or 2008 with my hp? It would be an easy add if it has actually been detuned as many have suggested. Also at that time the 911 would have increased in hp and the Cayman would no longer pose a threat.
Does anyone know what the specs are going to be on the Cayman non S?

Several sources have stated this particular fact.
DavidNJ has hit the real question. If 30 more HP is as simple as a chip change, then Porsche would have gone to a lot of trouble for nothing. Chances are, as he says, that a real de-tuning would be more profound and harder to undo. It would be quite costly to invest in a new cam, re-porting, etc. Having said that, I hope you're wrong, Dave.
