My new 982 718 Cayman S PDK

[Brian_Innes]

Steve,

Be good to see you at Oulton if you can make it. Bring the lid, and I'll give you a tour round in my 718.

Had a great day at Oulton Park. Good to meet up with forum contributors who were brave enough to sit with a pensioner having fun with a 718 CS PDK. 718 performed pretty well.

The Porsche Track Precision app was untested due to problems with my windscreen phone mount. Next year I’ll test it hopefully.

I’m looking forward to getting PS4S tyres fitted next month. Will track test them next year hopefully.

Good to meet you Brian and thanks for the trip round and my first 718 experience. Most enjoyable. Not a bad wheel man for a pensioner! The rest of our gang will give some thought to returning the favour at Knockhill next year as per your suggestion.

Brian, I was impressed with your late braking at the end of the main straight.

I could clearly hear your tyres skipping and squealing for mercy as you dropped anchor !

As you were doing it repeatedly there appeared to be no fade, which is impressive as you don’t have PCCB’S.

Without starting the 4 cylinder/6 cylinder debate, I would say at tickover, low speed, the 6 cylinder is supreme. When you went past the pit wall at warp speed, braking, exhaust popping, I must say it sounded excellent.

Robbie says I must upgrade my Cayman... mmm, thanks!

Archie.

Thanks all for your helpful and gracious comments on the Oulton Park track day. I had a great time.

The brakes on the 718 CS are very impressive. Compared to my previous CR with GT3 MC, braided hoses, and Brembo HP pads, the 718 is in a completely different league regarding track day stoppers. The 718 CS is surprisingly capable.

As for the engine sound on the track, when the flat-4 turbo is revving in the higher reaches it sounds perfectly fine to me. The "snap, crackle, pop" from the PSE on the overrun is quite appropriate on the track IMO. It's just a different acoustic profile. Anyway, after 10k miles I'm used to it by now.

Good news on my tyre order. The Michelin PS4S N0 tyres have now all arrived at my local Michelin retailer. The fronts were delivered ahead of schedule on November 16th to join the rears already in stock. I'm told I'm one of the first customers in the UK to receive the PS4S N0 from a official retail Michelin supplier.

I'll report back with more info and photos of my PS4S tyres after fitting.

Good to sit with you Brian --- what a great car !

Looking forward to benefiting from your experience at Knockhill !!

 

[Brian_Innes]

Chris,

Thank you for showing me the lines at Oulton Park in your Manthey GT4. Awesome grip and poise.

I'll be delighted to demonstrate the fast groove around Knockhill next year. The track suits the Cayman mid-engine platform extremely well. More so than the 911, including the GT cars BTW.

Hi all

this is my first post so here goes

just got a Cayman 2.7 ,this is my first Porsche ,have always had Mercedes for the last 15years .

first impresstions great car to drive goes round the many roundabouts in Milton Keynes unbelievable.

The only thing I find after the Mercedes is the very loud tyre noise the car has 20 inch Carrera S Wheels that do look very good with Goodyear F 1 tyres , do other owners notice the tyre noise or do you have to get used to it ,would a different make of tyre make much difference or maybe 18 inch wheels . I am also getting a noise when you reverse the car on full lock ,I think it’s the tyres when they are cold ,once the tyres have got warm the noise is not there . I have tried the start stop on the engine when stationary but sometimes the engine stays running ,and the sign on the instrument panel says it’s not available.?

To change the subject what do you all use regards Car Polish and Car Wax, I have been using Mer for many years on the Mercedes,and have still got a lot left ?.

Hope to have a few reply’s especially about the tyres .

Many Thanks

Regards Paul

Hi Paul, and welcome to Cayman ownership and to the forum.

I’m afraid big rear tyres in particular equals tyre noise. There’s really very little you can do about it, even by changing tyre manufacturer. I think that Goodyears and maybe Pirelli are at the quieter end of the spectrum anyway.

Tyre noise when reversing on full lock is a very common complaint, especially when air temperatures head downwards. Ackermann steering geometry and wide front tyres are the culprits, with the tyres skipping across the road surface.

There are plenty of “polishers“ on the forum to advise you about polish and wax choices.

Can’t advise on stop-start as I don’t have it on my 987.2 Cayman.

Enjoy your new car and do try to get along to a local Club meeting some time.

Hi Paul,

The engine management system looks for certain conditions before actuating the auto stop - engine temperature, battery status, etc. Page 117 of my user manual lists them all.

Hi Jeff

Many thanks for you info on the tyre clunk when reversing ,it’s put my mind at rest that this is a common problem and there is nothing wrong with my car ,wii have to get used to the tyres noise.

Hi Alan

thanks for advice about the stop start not always working ,I had a look in the handbook to see all the variables .

many thanks

Hi Paul,

Welcome to the forum and enjoy your Cayman. I never use the stop start function. The disable button is the first button I press when I get in the car as I think long term, it can't do the vehicle electronics and battery any good despite what the manufacturers say. On a hot day, you also lose the effectiveness of the aircon. Regarding polish, I stick to Autoglym and Zymol. I believe Mer is very good but it has some abrasive compounds in the formula.

Regards,

Gary

Chaps, this thread is about Brian's experiences with his Cayman 718S. If you want to discuss tyre "clunks", which polish/wax, start/stop etc. could you kindly start a new thread? Thanks

Thanks TS Captain.

Back on topic.......

Following a successful and most enjoyable PCGB Oulton Park track day last week, it has been very gratifying to receive extremely positive feedback from all who chose to sit in with me for a few hot laps in my 718 CS. Especially as a number of my passengers are well respected track day exponents, who are very accomplished wheel-smiths in their own right.

My 718 performed faultlessly, even allowing for the Pirelli P-Zero N1 tyres which were squealing and chirping in response to the demands of the chassis dynamics. Compared to my CR, this car is in an entirely different league. That's not taking anything away from my much lamented CR manual, but the R&D development of the 718 chassis, braking, and I would even include the quicker steering rack, have all moved the "mainstream" Cayman into a higher plane. The 718 as I have specced it, really is GT4 quick on undulating, technical circuits such as Knockhill and Oulton Park. I have the GoPro videos to back this statement up. When shod with Michelin PS4S N0 tyres I am expecting a further improvement in track day performance from the 2017 Oulton and Knockhill laps of 2.03 and 1.04 lap times already recorded from the videos.

I'm looking forward to resuming my track day exploits with the "proper" tyres in 2018.

Somehow along the way the title of this thread, in individual posts, changed! I have edited the last post to the original title so that subsequent posts so be the same.

To be fair to you Brian, I think there's also a lot more to come from you at Oulton. It is a very complicated circuit ... you think you know it and then you learn something that helps the car breathe with the circuit and takes another second or two off the time !

I think the car was working quite hard to keep up with the limitations of the tyres and your building experience ... I really look forward to you showing me around Knockhill which I have visited only once !!

Yes, it is GT4 quick ...

 

[Brian_Innes]

Thanks Chris,

Such positive comment on my 718 CS is very gratefully received. Especially coming from a fellow motorsport competitor who knows Oulton Park circuit as you do. My 718 CS PDK really is a surprisingly capable track day car as well as an effective and comfortable tourer.

On the subject of tyres, I have today viewed my new Michelin PS4S N0 tyres. They're looking great and the compound feels very business-like.

Tread depth when new is;

Inside edge to Outer Tread Block - 7.0mm

Outer Tread Block - 5.5mm

The tyres will be fitted to my 718 CS next week. I am minded to add a little more negative camber on the rear, currently -1.58 degrees. I'm thinking of adding an extra half degree negative to give -2.30 degrees negative on the rear. The front is already maxed-out at -1.28 degrees of negative camber with zero toe.

From my track day experience this year over 4 events, I think a tad more negative on the rear would better suit my 718's suspension spec and also my driving style.
