Thank you. Already understood that and was not specific enough in my comment. I specifically meant...the importance of range 1 vs range 2 vs range....and its impact, or perceived impact, on the motor.
Sorry that was a misunderstanding and once I re-read you replied. Impact...., who really knows to be honest? I've seen a bunch of over rev reports from reading through the forums, but nothing ever indicated anyone had inherent problems even extending into range 2 outside of disastrous misshifts. Pretty sure mine has some in range 1, possibly even range 2 from when my short shift kit disassembled itself going into 3rd.

Welcome! Trust me...I know. :-)

In any industry where lots of money is involved (like my other collectibles industry) people tend take a small bit of into and always think the worst and it shapes the market.
Sure..not debating their "every day" value and agree they should not been seen as "doom and gloom" but in their extremes perspective buyers should evaluate.
This car could have already been discussed; I'v had my head in the passenger footwell of my targa for the past 2 effing days and have not kept pace with the thread.
Sold for a very tidy sum. Apparently knowledgeable folks commented directly that the car had hit a raccoon. Seller stated that paint thickness readings indicate original paint.
Uhhhh, no. Raccoons are large animals. Big fat furry buggers. Hit a raccoon, buy a new bumper cover (for starters). Much better to assume a new, properly painted front bumper on the car, rather than original paint.
Not knocking the car in this case but I am putting the seller on my personal "beware: hijinks ahead!" watchlist.

TBH. In this market, I would have expected more from a C4. Pretty rare car. Although, the dirty carfax probably does it.
As an OEM to the VAG group and technical partner at the highest level of Porsche engine development, including the VAG groups Bugatti Veyron; there is no better choice that Schrick for your Porsche. They offer the worlds finest performance camshafts from premium blanks with complete in house R&N and manufacture from end-to-end.
We offer a variety of Schrick cams for a range of applications, these particular being the '996 Cup' replacements for the Carerra and GT3.
Talk to one of our engine consultants to guide you into the proper camshaft for your application.
I've read from multiple internal Porsche sources that regardless of marketing, Variocam was implemented primarily to increase MPG for tightening US and Euro enviro regs
Makes sense cause the Cup & factory race cars (not subject to EPA) don't use Variocam at all
IE if Variocam net increased performance Porsche Motorsports would be using it

To used car sellers bumpers don't count as original paint and the ad said the bumpers were repainted. Apparently in Europe that doesn't count either. I'm with them. Bumpers are plastic and meant to be bumped and painted. Metal body panels only apply for me unless it's a super low mile Concours car.
Not just variable valve timing and lift (and/duration), special intake manifolds (different internal valves that change runner length and alter resonance frequencies) and exhaust systems are also designed to extract the most torque across a wide range of RPM so that engine can develop more ‘area under the curve,’ (HP) which will make these cars faster overall, even if peak HP or torque stays the same. And being more streetable at the same time. And remember, some efficiency gains can be traded for power as well. If an engine is slightly more efficient, it could actually make more power.
So variable valve timing isn’t just about fuel efficiency, it’s about many things.
Good to know about the TT solenoids; I already knew it was far simpler on MKII but hadn’t looked at the Mezger’s
And what you’re describing about the power curve without Variocam is I believe why the other forum here abandoned the experiment; the car became too unpredictable on track, as I recall from their conversations
My interest a while back was in unplugging Vario on an MKI car with one faulty solenoid, that was misfiring badly. But I but the bullet and replaced it
Thx

Yes! Since the last 911 Turbo I remember driving would have been a 930 in the mid 90's, I was absolutely freaking SHOCKED at how quickly the 996 TT accelerates at low RPM.
You step on it, and the thing takes off like a bat out of hell even when you're in a high gear at low RPM. 5th or 6th gear on the freeway? Floor it and the thing will accelerate from 2000 RPM faster than anything short of a true super car.
At first, I thought it was just that they managed to put small turbos into the car to limit turbo lag but now I realize that the variable valve timing has a lot to do with the engine .'coming on the cam' early and THAT eliminates a lot of the Turbo lag.
I bought the car because a good friend of mine here encouraged me to and I'm glad I did. What a car.
Hope the purchase went thru. If so, welcome to the club!
Thanks! The purchase did go through! It is the second Porsche I have bought from a Rennlist member and the seller was great! The car exceeded expectations! And even at $10k more than the 996 I almost bought 4 years ago, I feel like I got a better deal today! I love the car and couldn't be happier! Aside from being my second choice of color, which I still love arena red, it is exactly how I would have ordered it from the factory! It is an early 99 (3/98) with LSD, Sport Seats, and M030, as well as a rebuilt engine to 3.6L with LN Nickies, IMS, and plenty of other upgrades! It'll be my daily for now, but after driving a few hundred miles in it I almost wish I didn't have my 951 track car! This is my first 911, and it is incredible!

the seller of the high mileage red 99 it’s a little tricky. I went to his warehouse in dripping springs Texas by Austin. He had like 6 996s. I saw that red car, body look good but car was dirty. Anyway the reason we went there was to pick my friends bat purchased 993. Anyway as I had introduced my friend to my mechanic my friend took the 993 there. One panel and door had bodywork and that wasn’t disclosed in the bat auction, number two car had oil leaks. Two of the Valve cover gaskets where changed car still has a leak. So if you go to the auction you’ll see my comment stating that I would buy at a good price expecting to have to put some money into it. Seller is also shady and many times does not respond or answers questions, request. I was interested in the car because it’s only 2 and a half hours away, plus I was going to put my ambers and 408s on that Red car, so it would be 100 percent stock. Then I was going to sell it as such, it’s probably pass what I was thinking about paying for it.

Beautiful 996! Congrats!
How about a few pictures of your 951. Got a couple of buddies that still track them. Incredible Porsches that still after 35 years are durable and fast. Got one buddy that club races the S2 which is set-up beautifully. In my avatar picture you can see his red front end.
Gonna hijack my own thread temporarily and cross post something from the 997 forum because I'm curious what people here think of this, especially those with advanced Porsche technical knowledge. There has been a rumor/urban legend for sometime that Porsche engineers built in an undisclosed trick that allows 997.2 4s PDK cars to seamlessly convert from AWD to RWD by simply engaging the handbrake 1 click in certain modes. Though discussed and ridiculed often, nobody had posted anything definitive until this was posted a few days ago. Just curious what people think of this since I know there is ample discussion of AWD to RWD conversions in this and other forums.
