Thank you all very much. You guys are epic. The color combination I find very elegant without looking too "flashy". She has a powerful presence without being an attention *****. I think that goes for all Turbos.
About the noise...I am a super virgin NOOOOB with no experience when it comes to tinkering with cars. I don't have the slightest clue on how to check, remove, or even determine where that pulley is. As for the clutch, I actually had the slave cylinder replaced based on recommendation.
Yes - I notice that disturbing noise only when in town, in between stop lights going no more than 30mph.
Yes - It seems the noise is triggered by slight warmth/heat as it only occurs in the daytime (avg temp where I live is 70deg day. gorgeous weather really) I haven't noticed it yet at night.
Nope - Nothing really happens when I depress the clutch. The intensity of the noise is reduced very very slightly for about half a second but back to normal. Noise doesn't go away at all.
The noise doesn't emerge upon start but after 20-30min of driving in daytime.
Since no one in our household is handy, do you guys think hiring the mobile car mechanics on craigslist is a good first step for basic diagnosis of the pulley, bearing and all the stuff you guys have suggested? It's such an awesome car to drive and this damn noise retards my enjoyment.
Thanks again for the tips. I don't want to look like a total tool when I get the car checked and repaired.

Below 70F the car/fluid doesn't get that hot and above 70F it does.
The hotter the temp the more frequently the noise appears. On real hot days driving through town making lots of stops, idling at lights, the noise can appear at every stop.
Get the car to a pro.
Get the car diagnosed by a pro.
Get the car fixed by a pro.
Pay the pro.
Go drive the darn car!
Sincerely,
Macster.

For a 996 Turbo in stock form, there is no need to exceed 93.5 octane. It isn't adding any additional power (in fact it is likely causing less power) and at 93.5 octane, there is little chance of the ECU be forced to retard the timing.

I won't ring the CL mobile mechanics. Sheesh I was only thinking of having them remove and "feel-out" the pulleys to see if that could be the culprit. I don't mind paying a premium for high quality repairs. My fear more than anything are costs associated with misdiagnosis while the core problem still lingers on.

Andrade? san Leandro?
Buy a flash from UMW, even his standard tune WILL benefit from the 50/50 fill.
Or fill it with all 100 and use the 100 tune.
But yes, get it fixed first.

PS Given the crappy CA gas, I think you DO see a slight benefit with higher octane even with a stock tune. I suspect that the stock tune is pulling timing, especially in hot temps, with 91. It would probably 'like' 94.... JMHO

Man I wish we had acess to this gas in my area. I have UMW stage two turbos and tune. In my 993tt with no tune, I used to buy race gas and mix it. I felt I could feel the difference over our 92.

it has become the bane of my existence since it's my nearest station carries it. i was paying 9 a gal and 150 a week for my special blend. but the car did wheelies, so was worth it. i've noticed gas prices really dropping lately, which isn't usual for summer. must be another sham election coming soon

But to put it into perspective, I pay £1.35 for 95 ron and £1.40 for 98 ron. This gives approx' figures of ( please excuse my calculations, as I use the British standard "Man Maths". This is where you round up while budgeting car parts in your head and round down when telling your wife how much it cost.)
£1 = $1.51 and 1 gal = 3.78 ltr.
£1.40 X 3.78 = £5.29 per US gal
£5.29 = $7.97 per gal.

PROBLEM SOLVED - the eerie high pitched noise is banished
I'd like to thank all of you and I did implement the knowledge you've shared. Sorry it took a while.
First I took my car to Bauer Porsche for basic diagnosis. They were a mere 8 min drive so by the time I got there, I had to rev the engine up to re-create the noise.
Once the noise was activated, the first thing I asked was to check the belt. Brian the technician showed me with a flashlight that the belt is good condition and intact. I could even see the white print on it so it was pretty new.
He immediately saw a "nipple" missing on the power steering reservoir. With a stethoscope we confirmed that the noise did originate from that area and that it was the part that needed replaced
Before taking her to a dealership for repair, I registered with PCA as per Macster's suggestion for member discounts. I chose Porsche of Fremont because they were mentioned on this post and I've read glowing reviews about them. Gunter and his service crew were very professional. They repaired my car within schedule. When asked if they found any other issues with my car, he said that it was KLEEEEEEN!
I was also able to use one of their loaners for a few days. I think it was either a 2011 or 2012 Cayenne S, I'm not sure. My husband who wasn't aware of my car issues thought I traded the Turbo for the Cayenne...and this bothered me but... he didn't seem to mind Anyway, the Cayenne is a nice SUV and will consider one once I pop out babies. Again, mad props to Gunter over at Porsche of Fremont. I will be taking my Turbo there for any maintenance or service needs even if they are not the closest.
And of course, mad props to you guys!
PCA referred me to the Diablo chapter and if you guys wanna hangout/B.S. I'm thinking of attending their member picnic event on Aug 26 in Livermore. I volunteered to bring unfiltered Dutch beer but the event is wholesome and alcohol free.
BTW, new part number for P/S res: 997-314-920-31 and pentosin chf 202
