993 timing slip cured - what a difference!
Discussion
I fully expect most experienced 993 owners are only too aware of this issue, but just in case it helps anyone else...
After several months thinking my 993 C4 was a bit flat (and fat), I asked that the cam timing be checked. Turns out that it was amiss, but not by much apparently.
Whatever - with it reset, the car has a markedly different feel - much, much sharper, and with a real bite to its acceleration. Feels like a proper sportscar now (although still a completely different animal to the RS).
Funny that, I just read on one of the PCGB Furum threads that, unlike the 996 variants, there was not a great deal of difference between a stock version and the 'more exotic' models. I am not that familar with the 996 versions - if the difference between my C4 (freshly fettled and with sports suspension) and RS is felt to be trivial, the 996 C2 to GT3 margin must be mind-boggling.
However, that's an entirely different thread. The purpose of this one is to highlight the benefits of having your cam timing checked (and adjusted).

Although I was aware that a C4 would be heavier and less responsive than my other car, I could not believe the huge gulf between the cars. It got to the point I began to wonder why people were so passionate about non-RS 993s. Having had everything else checked, timing slip seemed the only possible cause.
Specifically avoided a rolling road - I have been down that slippery slope before(a downward one, running parallel with your bank balance). I pretty much had a feel for how I imagined a heavier 285bhp C4 should drive compared to a 300bhp RS - and I was not getting it. I am now.
Not sure how much it cost yet - around a day's labour plus the parts to replace the felt washer I understand the accountants forced upon the 993 engineers. Who by? If you are who I think you are, you know who I used.
Until yesterday I was entertaing thoughts of a 3.6 C2 - don't think I'll bother now, the C4 will do as a daily driver until I succumb to a GT3.

Well that's the current plan.
Mind you, a couple of years ago I bought a 964 RS as my daily driver, but that was just too compromised for such duties. Thus my track record on sensible choices is somewhat lacking.
There was talk of a 911 Club Sport fulfilling such a role a few days ago, and the thought has not completley left my head.
Do your medical texts record a recognised obsession with lightweight 911s? Is there a cure?
