Do you not get the Chrono Package as standard in the RS 4.0?
Really puts me off buying one

...and it lowers the car by an inch or two which makes it look much better.
Non-PASM cars are fine, but are neither perfect for road nor track. Not that PASM doesn't have it foibles though.
PASM is 10mm lower.
Sports suspension and LSD is 20mm lower and some say it's too much, as in too low especially with aerokit.
I had thought about the cayman and boxter and to be honest I love the way they drive but they just do not have that special feeling that I get out of the 911.
The power is important to me and to be honest my 3.6 does feel slow but the Gen 2 will be a little quicker. I know I should hold out for the S and I may just do that.
having said that this one looks very good and is under warranty.

I get this, my Boxster was fast, or certainly felt a fair chunk faster than my 911 especially at the top of the revs, but there is something about the 911, even my early 996 that makes them a little special.
Do like the one in the link, some nice options as well.

Saw a GT3 RS for a bout 2 seconds as it blurred past me this morning. Orange with orange wheels and everything. Made a right racket, that thing must've had a different exhaust setup.
They all make a right racket, hell if you stick your head in the engine bay on a 911 it sounds like a load of bricks in a tumble dryer, even more so in a GT3. They sound broken at idle.
But a GT3 being booted makes an epic noise/racket. An exhaust just amplifies the racket more so!

hehe this is true but you grow to love the sound after a while, I did think my car was broken when I first got it.

I've heard one boot before, but not like this. It had a higher almost metallic tone to it. Sounded epic! Would be interested to see if it's been played around with.
I think i'm coming around to Porsche. Being brought up, my dad has never liked them and has always said so. He's a TVR man.

Bose you can live without if its not a cab I think, with a cab its pretty much a must have.
As for them sounding like a bag of nails... It is even worse when they are left for a few months and not turned over, mine was in the bodyshop having some work done to the front bumper a freebie so couldn't complain at the wait.
But that first start when I got it back... jesus I was convinced it was broken. It literally sounded like a bag of nails was dropped inside before it was turned over.
I'm told its to do with the hydraulic tappets.
Not in vario territory. Get it to 5500 and it starts to sound very good.
By the way that my car behaves I thought vario started at 4.5k rpm.
Details taken from Porsche's MY1999 Service Information Technical Introduction:
"VarioCam
VarioCam, the adjustment of the intake camshafts at engine speeds of approx. 1,300 rpm* and 5,920 rpm, produces a major part of the engine output, the engine torque as well as the good exhaust values at idling speed. Engine speeds below 1,300 rpm produce a slight overlap in the valve stroke curves for the intake valves in relation to the exhaust valves.
This particularly affects low proportions of hydrocarbons (HC proportions) in the exhaust gas before the catalytic converters. If the engine exceeds the 1,300 rpm mark *, the intake camshafts are adjusted by 12.5° (by 25° if measured a the crankshaft).
Adjustment of the camshafts to produce a greater overlapping of the valve stroke curves for the intake and exhaust valves results in improved cylinder charging and thus an increase in engine torque. In the case of engine speeds above 5,920 rpm, the intake camshafts are returned to the basic control times (as for engine idling speed). If the intake valve closes later, additional amounts of intake air can be drawn in. This produces a recharging effect since the flow of air is not interrupted. This also results in improved charging of the cylinders and an increase in performance.
* The value 1,300 rpm increases to 1,480 rpm with engine oil temperatures of approx. 133°C."
"VarioCam
To increase the torque and to improve cylinder charging, the engine has two VarioCam actuators which are installed in the chain tensioners of the camshafts. The two actuators are operated by electromagnetic valves activated by the DME control unit.
Functioning
When the ignition is switched on, the electromagnetic valves of the camshaft adjusters are supplied with positive potential. If the engine is started, the control unit applies ground to terminal 25 (camshaft adjuster for cylinder line 4 - 6) and to terminal 52 (camshaft adjuster for cylinder line 1 - 3) if the following conditions are fulfilled (VarioCam activated);
1 - Engine oil temperature between -3°C and 133°C
2 - Engine speed > 1,300 rpm
3 - Throttle opening > 5%
or
1 - Engine oil temperature > 133°C
2 - Engine speed > 1,480 rpm
3 - Throttle opening > 3.9%
The ground potential is deactivated by the DME control unit (VarioCam deactivated) if:
Engine speed > 5,120 rpm"
...................... Doesn't at all explain what happens at about 4.5k rpm in mine.

If your interested the 3.6 has Variocam Plus,
"1584 Variable camshaft timing with valve stroke control (VarioCam Plus) The demands placed on the design of an engine, i.e. increased performance, improved driving comfort, observance of legal emission limits and reduced fuel consumption, result in contradictory construction criteria.
The idea behind the development of the VarioCam Plus was to create a variable engine which can be optimised both for maximum performance and for frequent use in urban traffic or on main roads.
A system to adjust the intake camshaft to vary the opening and closing time combined with a valve stroke adjustment system is the solution to this problem."

I would have thought that the biggest change should be at 5.920k when the cam returns to its standard timings. Meh shows what little I know.
Do know that I want a gt3 so badly.
Mine is exactly the same point, 5500rpm and if you look at dyno plots from it you can see a dip in power which is done on purpose by Porsche due to some emmisions rule and then the car starts to make real power too. Feel like a cam change but is not I believe, but the sound changes and the car pulls even harder.

Sounds like about 7000rpm to me, but he/she isn't full throttle so you don't quite get the full sound. It's still a nice example of the tone. I blat through that tunnel whenever I get the chance
