Looks great! Enjoy

Those boxster 19s look really good. Could help save a few £££s

The display speed limit option seems to have disappeared from the right binnacle. It's on the map but I liked it floating on top of everything on the right.

Car looks great, wheels, choice looks good with agate grey & red hood.................enjoy

[Timbola]

fk me that's nice.

Enjoy fella.

The black /red bicolour leather with the deviated stitching looks superb, excellent choice!! A nice detail improvement over the 981 full leather is the stitching running down either side of the central console, even if I do prefer the flush dash top vents of the previous car. I'd always have the full leather option, makes all the difference! Yours looks better without the sport chrono "wart" which again is no longer nicely integrated as it was.

Thanks to everyone for their kind words.

Is it wrong at my age to be considering sleeping in it?

Love the black/ Bordeaux interior after seeing the photos I am going for that on my Cayman.Enjoy the car.

Given the 4 is similar design to 6 turbos just two cylinders removed I suspect under street use these motors will be ok. I'm most interested in how these 4 cyclinders do heat wise on longer track sessions. I'm sure they will be fine for first 3 to 4 laps but what happens if session goes over 10 minutes ? Anyone track their 718 yet?

Don't know the answer to that - but quite a few modern cars wind back the power if things start to get too hot.

If a car's been thrashed it's usually better to keep driving gently for a few minutes rather then just parking up and switching off.

That has always been the best way to look after the turbocharger, run the engine on light load, that way the lubricating oil is kept flowing through the turbo's bearings, taking the worst of the extreme heat (up to 1,000 deg C) away. Shut down straight away and that oil will simply bake.

What a great idea chaps.

Take a nice shiny new unknown engine, thrash it round a track eh?
Just to see how fast the car goes, when you already know how fast it will go, and just see if it boils up.
Well, if thats sensible I have no compassion for any idiot who toasts his engine......

I'm really struggling to have any possitive thoughts for the 718 if anyone does that.

Am I the only one who thinks thats.
I apologize in advance if I am......... I'm sorry

It's fundamentally different - read https://en.wikipedia.org/wiki/Antilag_system - it was often referred to as bang bang and relies on burning fuel in the turbocharger to keep it spinning. <snip>

Probably best that we agree to differ on how similar or different these systems are in operation. I'm an engine development engineer by background, but I'm not about to argue with someone that has found and absorbed a Wikipedia page - surprisingly accurate one I'll admit.

In the ways of Pistonheads naive it is you are, young Liam.

Even if you'd actually designed this engine, someone on here would know more about it than you.

ETA: congratulations on the new car SparkyHD - enjoy every moment.

So that everyone knows, or mist my previous post.
There is evidence that 4 pot engines that are turbocharged are causing the car construction industry to think twice about where they are going.
I'm hoping that Porsche will not suffer this problem.
But industry specialist have accepted that the failure rates have risen over the last 10 years. The rise is a percentage rise in failures and not just because they are making more.
The figures don't lie, this is just a fact.
And this does not mean that porsche will be necessarily affected, and I'm just hoping that they won't.......possitive vibes please.

Gadgit

I've been running 4 pot turbo cars as my "hacks" for over 10 years now, and they have generally been more than 10 years old at the point of purchase (Volvo 940 estates, think I'm on my 5th one now). What goes wrong? Nothing much really - turbo oil seals at 150,000 miles. Need to keep on top of corroded radiators. 1 of them did a head gasket, but previous owner had upped the boost quite substantially.

I don't think there's any endemic reliability problem built into the formula, it's just the surrounding parts that need to be sufficiently well engineered. I don't think Porsche will be affected - if there's a company that knows what it's doing on the engineering side of things, it's probably them, and they are not short of turbo experience. 300hp from a 2.0 litre and 350hp from a 2.5 litre isn't exactly over the top for turbo engine specific power output. High revving NA engines with high specific power output are probably more of an engineering challenge, despite having less parts to engineer.

No, of course not. But consider your own bed as well - it will still be there when you wake up.

Great looking, and just such fabulous cars to drive. Temporarily jealous, I hope not for too long!

Rather than make snidey comments why don't you read the references, do more research if you need to (I have), and then form your own view as to how similar the mechanisms are.
