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

I appreciate that you have taken the time to look into this, however, you are contradicting a professional engine development engineer.
If you follow this thread you will see where I questioned a definition of turbo lag and he explained, for which I thanked him. It is my view that this forum might be better if this happened more often.
In any case, my apologies and good luck to all those collecting their 718s.

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.

Are you really trying to suggest the the Volvo 940 engine is related in any way to the Porsche 911 996 and 997 and that because your volvos were reliable that means that porsche are as well?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 think I understand what you mean, but a Tank engine in a volvo as you have found out is legendary for the right reasons for reliability.
Try to explain why companies are replacing 100s of gen1 engines all over the country in 996s and 997s.
I suspect that all those people that have been bitten by this grose incompetence at Porsche would feel that through that large period, they didn't know what they were doing. Or new, and did nothing ?
Hoping to god that my 981 will be fine, but I'm sure there will be some on hear that are now buying a porsche hoping it will last, who have like others just moved into a new one.
All I can say is good luck to everyone, I keeping my fingers crossed rather than relying on history.

No, of course not, but your statement was that 4-cylinder turbo cars are viewed by "the industry" as endemically unreliable is not supportable for the 718 until the cars have been run for long enough. Keeping your fingers crossed probably won't make a lot of difference, certainly no more than relying on history. It's not about luck - it's about how good a job they have made of developing the new engines. Time will tell.I think I understand what you mean, but a Tank engine in a volvo as you have found out is legendary for the right reasons for reliability.

Wasn't aware that the 981 had any specific reliability problems, but I hope yours is everything you want.

Thanks. Interesting. 186mph! Fookin' ell.http://www.automobilemag.com/news/2018-audi-tt-rs-...

Posted the same review in General Gassing.
186mph is pretty mental indeed.
The reviewer's summary with "What sets these two cars apart philosophically is one simple fact: The Porsche is a sports car, the Audi is a very sporty car." does chime.

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

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?
Keep oil temps/air temps down and it will be fine. Im sure its rigorously tested. Do they come as stock with an oil cooler?gadgit said:

I think the unreliability of the first generation water cooled Porsche's need to be put into perspective. When Porsche developed these engines they were virtually bankrupt and simply couldn't afford huge research and development budgets. Today they are transformed into a wealthy and highly profitable business that not only can afford to but has to produce reliable and thoroughly developed products. As far as I am aware there have been no issues with Porsche engines since the new design DFI were introduced (apart from early 991 GT3 con-rod bolts). As much as I'm no enthusiast of the new flat four turbo engines I am sure they will also be very reliable - as long as with any machinery they are not abused and properly maintained.I suspect that all those people that have been bitten by this grose incompetence at Porsche would feel that through that large period, they didn't know what they were doing.

True in some sense but I think its quite important to remember that those engines have been produced at least 10 years, without any proper update. My indy (who used to work at porsche and built several engines) says, if you have a water cooled porsche (m96/m97) that produced between 1999-2009, and did not suffer any engine issue, there is only one scientific explanation: You have been very lucky! 
To contribute positivity, if 718 owners do not report any major engine fault in the first two years of ownership or 50k at least, I would be getting in the line too, if this brexit won't bankrupt us all in the near future, who knows, lol.
Went for Test drive in 718 Cayman S yesterday ( stuck in traffic (accident) on A23 for 45mins - felt pretty awesome judging by all the looks the car was getting) in Miami Blue, colour was out their, but a bit bright for me, dealer had Black metallic looked absolutely stunning ( past experience of keeping a Black car looking great is hard work), but ok I'm probably boring but staying with Agate grey.
Did see 911 Carrera with 20" S wheels in satin platinum, not cleaned & had loads of break dust on wheels, but due to colour of wheels you wouldn't have noticed from a distance, so glad I opted for these in same colour.
Be aware if you go off std spec ie none std seat colours it will add 80days to delivery date + painted side air intakes are subject to time delay.
I firmed up spec yesterday (placed order in July), was told looking @ Feb/March earliest

Anyone thinking about ordering one: don't bother with the 18-way adjustable seats. The two-way ones are lighter and more importantly they hold you better and are a lot more comfortable.
That cheers me up! One of the should I / shouldn't I decisions I thought I regretted was not opting for the 18 way adaptive sport seat plus when I ordered our BGTS! I have the standard (in the GTS) 2 way electrically adjustable sport seat plus which I find supremely comfortable. SWMBO found the 18 ways too constricted in the seat back bolsters, even when fully deflated, but would have found the adjustable seat squab angle and depth a benefit! Probably the single decision we thought about most. FWIW I find the sport seat plus more comfortable than the 18 way....As well as weight saving also saved nearly £2k!Edited by dreamcar on Tuesday 27th September 12:47
