BJ InnesMy plan for the air intake grill mesh needs further thought. I had intended to affix the mesh directly behind the plastic grill with Gorilla tape. This may be turn out to be problematic, as the mesh would make the subsequent removal of the grill impossible as it wouldn't then be possible to get fingers in behind the grill to squeeze the clips from their mountings.
BJ InnesJust returned home today after a 350 mile round trip south from the Highlands to Knockhill circuit in Fife. The weather forecast looked good but in reality, although it started dry, heavy hail showers blew in from the west across the Forth valley, dusting Knockhill with swirling white granules of icy hailstones. As if this wasn't bad enough, the Knockhill track has been completely resurfaced over the winter, and the surface was extremely slippery. The final phase of new tarmac was only laid yesterday! It was still oily in places. The Hairpin corner for example, had low grip similar to that of the PEC Low Friction Handling Track. Top Gear style oversteer slides were the default result. High G-force figures and decent lap times were just not possible today due the lack of lateral grip. My best lap today was a 1.02, with 1.31 LH G-force. However, I decided to press on with the test session as the principal purpose was to reassure myself that I was still up to scratch for the forthcoming track day season. The second purpose was to track test the PS4S N0 tyres and revised geo settings. I can say in all honesty, that due to the track conditions, it was me that was tested more than the tyres or geo. Today was the most challenging track conditions I have experienced at Knockhill for 30 years. Some corners had slightly more grip than others, but all in all I couldn't commit to any of the corners with full confidence. Having said that, the re-profiling of the kerbs will make the track faster and more even satisfying. Once the new surface is rubbered-in it should be mega. The PCGB track day in July promises to be a thrilling experience. Be there if you can. So to the Michelin PS4S N0 tyres track performance. The best wet weather tyre I have ever experienced on any of my Caymans. Very consistent, progressive breakaway, not in the least snappy, and with astonishing wet surface grip on the parts of the circuit that could be considered "normal". Steering inputs are instantaneous and so sharp. Some of this may be due to the revised geo, but the sidewalls of the PS4S N0 seem to transmit a much better "feel" than the P-Zero N1's ever did. I did several laps in heavy sleet with the track absolutely streaming wet, and even at speeds of 115mph water dispersal was exemplary. Likewise, heavy braking in soaking conditions with the ABS pulsing like mad, did not present any dramas from the PS4S N0 whatsoever. Ultimate dry grip was not tested due to the track conditions today. That will have to wait until another time. On the homeward leg back to the Highlands, I took the scenic route from Grantown-on Spey across the moors where a dry, and traffic-free road beckoned. The new geo is absolutely spot-on for my 718 CS. The relatively high level of negative camber I have been able to dial-in is no doubt assisted by the -20mm lower PASM. It certainly sharpens up the steering, aided by the superb PS4S N0 tyres. The 2 degrees of negative on the rear axle is absolutely perfect for my taste. It doesn't cause the front end to push, and in concert with the new tyres, my 718 CS is now the sweetest handling Cayman I have ever driven, including my much lamented CR. (Qualification: I have never driven a 981 GT4 on the track.) Finally, a word on the BMC cotton air filter. I can't say I notice any performance advantage on the track. On my 350 mile round trip today, the longest trunk route trip since fitting the new filter, the mpg was probably the best I have ever recorded on the A9 at 34.6 mpg. Normally this same route recorded no more than 31-32mpg. The engine is even more free-revving now. For example, today the rev-limiter intervened at 7600rpm while exiting the slippy hairpin corner. The engine seemed to soar towards the red line with an added eagerness.Well worth the effort to fit the BMC filter I'd say. As I passed muster today on a personal basis, the PCGB track days already committed to and confirmed, are Blyton Park, Knockhill, and Donnington Park. I'll be at Anglesey as a spectator, and possibly Oulton Park in October is looking positive at the moment. Brian
BJ InnesOn the 21st December 2016, following an agonisingly long wait, at times accompanied by bouts of self-doubts attributed to the sometimes disparaging reviews of the 4 pot turbo engine, I at long last became the owner of an individually specced Graphite Blue metallic 718 Cayman S PDK. The DVLA V5c form shows the "Vehicle Type" as a 982, not a 718 as the marketing suits have designated the emissions driven flat 4 turbo model. Whatever moniker you choose to label this new Cayman with, one thing is certain from the outset. This car provides a very different driving experience from my previous 987.2 Cayman R manual. I intend to report in more detail on this topic following the conclusion of my self appointed running-in period of 1000 - 1200 miles. The spec I have chosen is mainly driver focused with a few comfort and safety options attuned to the purposes for which I intend to use the car. The full option list is as follows; PDK with Sport Chrono pack, mode switch, and dynamic transmission mountsSmaller diameter Alcantara GT steering wheel with mode switchPorsche Torque Vectoring (PTV) with mechanical differential lockPorsche Sports Exhaust (PSE) with tail pipes in silver-20mm lowered PASM sports suspension20" Carrera Sport alloy wheels, front 8.5" wide, rear 10.5" wideSports seats plusSide air intakes paintedRear apron paintedPCM navigation modulePorsche Connect PlusAlcantara gear selector and storage bin lidElectrically folding door mirrorsPark assist front and rear with reversing cameraLane change assistPower steering plusCruise controlSeatbelts in silver greySmokers packAluminium fuel capBi-Xenon headlights with Porsche Dynamic light system So far, I have driven the car only 214 miles, including a trip to Cullen on the Moray Coast on a surprisingly mild Christmas Day, where the attached photo was taken. First impressions are good. Having jumped two generations of Cayman from my previous 987.2 CR manual, to this, the 982, the upgrade in cabin quality and refinement is immediately apparent. Even allowing for my self-imposed 4000 rpm running-in rev limit, the early arrival of prodigious quantities of torque from 2000 rpm upwards, means the considerable poke of the 2.5 litre turbo is all the more accessible and rewarding. Now, I had better cover the engine in the room.........Firstly, I absolutely loved my CR manual with it's fizzy, tactile steering and the glorious stepped urge as the revs soared through 4000, 5000, and again at 6000 onwards to 7400 rpm, as the variable valve timing and lift kicked in. It was pure shock and awe. The trouble was, this joy could not often be safely enjoyed on the public roads as illegal, licence threatening speeds were attained just as things were becoming fun. The 982 offers a very different power delivery experience with the new flat 4 turbo. It's sound is more of an industrial drone than a banshee wail, with a ECU induced pop, crackle, and bang to break the monotony. At this early stage I have been selecting Sport mode on the steering wheel dial and using the paddles to shift the cogs just as if I were driving a manual car. Picture this, approaching an intercity dual carriageway roundabout in 6th gear at say 70mph, click the left paddle rapid fire style down to 2nd or 3rd gear, throttle blipping pre-programmed in Sport mode, tuck the nose around the roundabout with the new delightfully quicker steering rack, squeeze the throttle on the exit and the car absolutely flies. No lag, no emissions flat spot, just pure and simple get-up-and-go. This car is more easy to drive by way of it's accessible torque delivery than any previous Cayman I have ever owned. I say this having owned 4 Caymans over the previous 8 years and driven over 75,000 miles in total. I shall leave it there for now, as there are many more aspects of this new 982 to cover as I get used to living with the car. I am sure there will be things that will niggle and annoy, no car is perfect. Those who know me will attest that I am also a track day fan, and I shall be commenting on the 982's performance at Knockhill circuit in Fife, compared to that of my CR in due course. Hopefully on the same sticky track day rubber, in place of the latest evolution P Zeros with which the car was supplied with. Meantime I am still digesting the owner's manuals and trying to get the hang of the Apple Car Play stuff. Driving I can do reasonably well, when it comes to computer software and smart phone techniques, I am still on a learning curve. Brian
