Now run in and living up to expectations

I'm not sure how relevant this is to anyone else, but I thought I would put some comments together.

I followed the instructions and didn't go too mad straight out of the box.
I kept below 4000rpm and avoided max throttle for the first 500 miles, then kept below 5000 with only a few max throttle attempts when warm for the next 1000 miles.
I know the manual just says to avoid motor sports, sports driving schools (i.e. track days) and high engine speeds, but I thought I would follow the same regime as my previous cars which seems to have served me well.

Anyway, having done 412 miles yesterday, it is now fully run in.
Fuel consumption over 8 hours of mainly motorway driving (plus a bit of traffic jams and city driving) was around 24 mpg, which is pretty good.

Typically at the end of it I got out of the car with no aches or problems even with the sports seats, rather than the comfort ones I had on the previous car. My shoulders did ache at one point, but after a brief stop for 20 mins all was fine.

Judging from the guage I seem to have used about 1 litre of oil in 1700 miles, which is perfectly acceptable.
It still smokes sometimes when starting from cold, but it seems to be something like every 15 or 20 starts. I haven't yet mamaged to figure out what causes it, it doesn't seem to be the angle it is parked at, or how long it idles before you switch it off, or how hard it was driven before stopping.

Having played myself in now, I have been pushing it harder.
It is living up to expectations and the power delivery is exactly what I wanted. While normally aspirated cars may be more immediate with a clearer direct connection between your right foot and the engine, I like turbo cars.

When accelerating hard it is great the way it keeps the boost between gear changes. The most impressive part is the thrust you have available even when doing 60+ mph. Without trying I have been leaving people behind easily. Pulling away from toll booths is fun too.

I have watched the boost guage and have so far seen it get to 0.8 bar. I thought the X50 should allow it to get to 0.9 but perhaps this is right at the top end where the torque is trailing off. Some more experimentation is required.[:D]

I was also forced at one point to use 95 octane petrol. The car runs on it OK, although it seems to be a little less urgent (but that might be psychological, since I am not convinced you can easily tell the difference).

When starting from cold I have also noticed it takes a while to settle into a smooth tickover. Also, is the tickover supposed to be 750rpm?

I've also noticed that in general I get more respect from other road users, who seem to be less aggressive towards me. It all makes driving about quite easy and stress free.

The rattle I had from the back was from the relay that controls the rear wiper. It was not fastened properly. Whether it was not put in right, or knocked when the trim was installed I don't know. Anyway having removed the rear trim the OPC fixed it back in, took about 10 mins.

In summary, as a road car, it is fantastic. I also think that I might almost have enough power now.
The only downside it what do I lust after now? I can't think of any road car I can use everyday that could give me more safely usable performance (especially not with sat nav, climate control, integrated phone, 12 speakers - all of which are used regularly).
 
Stuart, glad to see your getting the full potential from the car, I first started at 20mpg but after the recent trip the car is now returning 24-25mpg.
My rattle now seems to be sorted (no idea what it was, OPC didn't say) so enjoying the sunshine (whats left of it).
On a run to Wales next weekend and quite looking forward to it.

Stuart, glad you are enjoying the Turbo experience you have to find a route into work that involves as many 2nd gear bends as possible, to ensure adrenaline levels are kept at Max! The only thing that consistantly pains me is the adaptive ECU, this is supposed to adapt to your driving style, but if you do a daily commute in nose to tail traffic (as I do)
after a good few weeks you get a softer turbo input to your right foot, you can re-set it by disconnecting the battery (codes & keys at the ready) & this transforms the instant pick-up, but it's still a pain & it happens even though part of my route is a B road blast. Watch out for this Stuart! Anyway keep us posted on the beast.
P.S.
19.4 mpg..I obviously have a heavier right foot!
 
I had noticed that it does seem to adapt even in the short term.
Driving gently in traffic seems to result in a bit less enthusiasm to deliver the full monty, I was wondering whether this was temporary, i.e. a couple of foot to the floor episodes would convince it that sporty service should be resumed. It could be my imagination though. The problem is that it gathers speed so fast, you run out of road and the opportunity to nail it only lasts for a couple of seconds. As soon as you lift the boost goes. Unless you are on a hill you just don't need any significant boost at a steady speed (no matter what speed you are doing). However, if this is the biggest problem, then I don't have much to complain about.

If you disconnect the battery, then reconnect it again, all the everything should be OK, apart from the clock needing reseting. Why do you need "codes and keys" at the ready?

Fuel consumption is around 22-23 on the run to work (bit of B road and the M3, average speed of 55-60 according to trip computer, although I have got the average to be around 70 a few times), around 24 on long drives and comfortably in the teens for shorter or more enthusiatic driving. If you are edging along then I am not suprised the economy is worse.
One of the good things about Porsche's literature is that the economy figures are actually accurate (for urban, non-urban and combined).
I don't really worry about it though, I just thought I would mention it since I think it is remarkably good and a significant advance over all the competition. One of the key improvement factors for the 996TT over the 993TT is the improved economy (or so my books tell me).

I saw a GT2 at the services on the M40 on Saturday. Since he was putting some oil in, I had a look. The engine bay is identical to mine. I thought there might be some difference, but nothing obvious.

The only other thing I have noticed is that it is affected by cross winds more than the C4S. I can't think of a reason why this should be. It's not enough to worry about and I will monitor the tyre wear to check for any tracking issues.
 
To add my fuel figures are from the Europe trip which did involve alot of straight line cruising.
I would love to get that all the time, after my last post, on a recent run to the airport (left the car in carpark[:mad:]) returned a quite reasonable 22mpg. Can't moan at that!!
