Porsche 911T Project - More Cosmetics

While I was much happier now - the yellow paint mis-applied to the car was showing some signs of a shine - I still wasn't happy with the slab sided look it was currently wearing. An obvious solution was to fit some ST style 'P O R S C H E' decals in black to match the pinstripe on the bumper.  

The various scratches on the engine lid were also something I found hard to ignore, and the blotchy sills where I'd filled in the trim fixing holes really stood out. 

So I had pretty much made up my mind to take the car to a paint shop. And while I was at it it I got them to paint the bonnet and engine lid black, just for the hell of it.

Actually, the paint match isn't anything like as good as it appears in these pictures, the sills are several shades lighter than the rest of the body. And the paint on the engine lid has settled a little where I'd filled the line of holes, but I've resigned myself to living with this until I can get the car re-painted.

Still, it looks ok from 10yards away!

Hello Winter

Its that time of year again. I changed the wheels on the Golf at the weekend, from the factory delivered 17" alloys with fat low profile summer tyres to my set of winter tyres on 16" steelies.  

This is my third winter using specialist cold weather and snow rubber on the daily driver-  in my case Continental Winter Contacts in 205/55R16. I also enjoy the bonus of a very noticeable improvement in ride delivered by the deeper sidewalls - it was the first time I'd used them with the uprated Bilstein B12 kit fitted to the car earlier in the year, and the combination works together brilliantly. 

Call me an old f*rt, but I sometime wonder of the grip provided by rubber band tyres is worth it.

I became a winter tyre believer one afternoon shortly after I'd had them fitted for the first time. A sudden dump of snow left the Sussex roads surrounding my place of work a treacherous rink of fresh snow and hard packed ice. At the bottom of a nearby hill there was a long line of cars waiting while various vehicles struggled to the top. The hill itself was a mess; cars and vans in the ditches, others trying to drive up the verges, and progress only possible when groups of desperate drivers and passers-by pushed. And even then I could see some pedestrians struggling even to stand up on the icy slope. 

As I drove slowly down the hill I tried the brakes, expecting the feel and hear the chuntering sound of the ABS system. There was no chuntering, the car just stopped. I tried again - a little faster - with exactly the same result. From the driver's seat I'd estimate the grip available was similar to that expected on a streaming wet road. 

I had a stress-free drive home, enjoying the looks of offended mystification on the faces of other drivers as I slipped past them tracking straight and true while they hung on to their wheels for grim death.

If UK drivers fitted winter tyres at the on-set of the cold weather, the utter predictability of this happening every season would be much diminished.

911T Project - Cosmetics

One big advantage of having a car with lousy paintwork. Its very difficult to make anything worse. So I was quite prepared to come back from Halfords with an armful of various products and get stuck in.

The paint on the car varied from dull/shiny to rough and unfinished - mostly around the panel shuts and the glass fibre bumpers.

I started with a bit of clay. It produced a lot of contaminants and smoothed the best of the paint, but it didn't do much to improve the shine. Next stage was a paint cutter. I tried an Autoglym product, but it was too gentle. The traditional 'T-Cut' worked better, and after a follow-up polish, I started to see an improvement - at least on the roof, wings and doors. 

The same approach wasn't enough on the worse rough paint, I needed to cut through the rough oxidisation. After some hesitation I tried a bit of fine wet & dry. It was what I needed. Over a week or so I attacked the area around the engine lid, under the headlights, and the door shuts. The paint there was contaminated and I found myself with base coat showing in some areas, but at least I now had a car that was more or less glossy - and from 10 yards it even looked pretty good.

The single door mirror was a matt-black square job. But I noticed that where it had been scratched a chrome finish was revealed under the black paint. After several hours careful chipping away with the blade of a craft knife I ended up with a chrome mirror. Another good result.

A further trip to Halfords resulted in the acquisition of a fibreglass repair kit and some filler. Using this I was able to repair the cracked front spoiler, and replace the 50p sized chunk missing from the lip.  Much energetic cutting and polishing later and the paint even returned something close to a decent finish. I used the same approach to fill the line of holes across the engine lid. That went ok, but my attempt to apply some paint (a Fiat yellow looked a good match) wasn't so successful. More DIY paint was needed on the sills when, with the aid of a heat gun, I gently removed the self-adhesive rubber strips the previous owner had stuck on, only to reveal a line of holes on one side. 

Earlier, I'd ordered some stickers from Highgate, a RS-style black coach line for the bumpers, and a reversed out S/T inspired decal for the rear. The combined effect was to  break up the yellow, and visually lower the car. 

Finally I replaced the reflective numbers plates with the pre-73 silver and black type that are correct for my car*.

I even felt brave enough to take the car up to a DDK event, and hesitatingly parked in a line up of other 911s, their perfect deep paint gleaming in the sunshine.

It was a start, but the deep scratches on the bonnet the blotchy result of my attempt to paint the engine cover still worried me.

Then at the Goodwood Festival of speed I found myself standing next to a white 911 hotrod.......

* The local DVLA office insisted that Tuthill register the car as a 1972 even when faced with an official Porsche document showing a July 1973 build date. It meant 'historic' tax-free status and I wasn't going to argue with them! 

911T Project; Paint Envy

At the end of April I headed over to Banbury to collect the 911 from Tuthills.  The country was drowning under weeks of biblical rain, but this particular day was dry, even warm, and I was looking forward to a drive back to the south coast in my 'new' car.

It was waiting for me in the yard's car park, looking shabby and neglected. But I'd said I wasn't worried about the cosmetics, hadn't I? After paying a bill that made my eyes water, my ears bleed and gave my cheque signing hand palsy, I jumped in the ready for the off. Richard wandered over to give me a briefing, and we messed around fitting pedal rubbers. His final words were "Well we've done what with we can with the fuel injection system - its still not perfect but see what you think". He may have mentioned some tips for cold and hot starts too.

I didn't listen to a word. 

After months of planning, dreaming and waiting I was finally driving my own old 911.

I'd picked a route along the old Oxford Road and then cross country via Abingdon, Ascot, and then down the familiar route through Petworth to home. 

In the sunshine I had a ball. Sure, the car was noisy, smelled of oil and the gear change needed gentle persuasion for find a ratio, but the steering was light and chatted away, the engine did its air-cooled buzzy thing, and the sunroof even opened. The ride on the fat 60% aspect ratio Continentals we'd selected was fine once you were up to speed, cornering was flat and the driving position was perfect  

It was a great drive, I even called ahead and arranged to meet a friend for a pub lunch. And I took a photograph:

Five minutes after this picture was taken I broke down. The motor span, the engine caught, but didn't run. Luckily my friend was gone and missed out on my humiliation. All I could do was call Tuthills and see if they could suggest anything. 

The fix was easy, and something I became very familiar with over the next few months. When attempting to start the warm engine I'd used a little too much throttle; the cranky CIS system had then produced a backfire with enough energy to unseat the air box, and the resultant air-leaks leaned off the mixture to the point where it wouldn't run. Refixing the air box (using the two highly engineered rubber straps) brought about movement once again, and a couple of hours later I parked up in the garage at home. 

I then spent a lot of time staring at the car. You know the scruffy matt yellow paint  job that wasn't going to bother me? 

It did. 

Badly.

As did the holes left by the previous owners attempt to add a whale tail to the rear, the chunk taken out of the front spoiler, the scratches on the bonnet, the rubbish extruded plastic sill trim, the sandpaper rough 'finish' on the door shuts and bumpers and the stone chips on every panel.

I spent the evening admiring the stunning paint on the R-Gruppe cars I so badly wanted to emulate and came up with a plan.

Skin

Why is it that many of today's cars, which bear almost no relation to those built at the dawn of motoring, still share one single component; a seat covered in dead animal skin?

Don’t get me wrong, dead animals have their place; its just that covering car seats isn’t one of them.

The stuff is freezing cold in the winter, likely to give you 1st degree burns on a hot day, and is slippery all the year around. It was originally selected because cars usually didn’t have roofs, and needed a tough seat covering that would stand up to the elements. When car builders eventually realised that a roof was a good thing, we all moved on. Take a look in the back seats (where the owners' bottoms rested) of an upmarket saloon from the 1920’s and you’ll find rich fabrics; the skin was reserved for the paid help up front who drove the owner around.

I appreciate that previous attempts to find a replacements for the stuff haven’t been all that successful; the 50s gave us vinyl, and the 60’s leatherette. Those efforts simply recreated the weak points of cow skin, and removed the one good point; the nice smell. A 70’s beige velour might not have been very much better, but at least you didn’t skid across it before hitting the (vinyl) door trim when trying to engage in what passed for enthusiastic cornering in those days.

My nearest branch of Millets is crammed with racks of warm, wind and weatherproof clothing made from high tech fabrics. The motor industry is capable of building vehicles with complex hybrid drivetrains, featherweight carbon chassis, and which pretty much drive themselves.  

Surely, a seat fabric that cools or heats as required, feels good to the touch, and grips you comfortably is not beyond their ability?

AC Cars and Porsche

I picked this snippet up from Trevor Legate's recent book on the Cobra.

In the late 50's, AC Cars were developing a replacement for the ancient 6 cylinder engine that had been used in AC's since 1919. Designed by their chief engineer Marczewski, it was conceived as (somewhat remarkably) an air cooled cylinder boxer that was to be built as a 4 and 6 cylinder.  A 6 cylinder version was fitted into a prototype Greyhound.

They had trouble, and Legate mentions "a visit to Porsche to discuss problems encountered with the smoothness of the engine.{which]...bought to light problems that could only be rectified by the design of an entirely new crankshaft. This was beyond Acs limited budget and the project faltered'.

AC then went in to use Bristol and Ford UK 6 cylinder engines until Carroll Shelby arrived on the scene. 

Its fascinating to think that AC could have had a air-cooled flat 6 engined sports car years before Porsche did.

911T Project: Pedals

The final part of the ergonomics equation was the way the pedals were set up. My objectives were simple: a good brake feel, and an ability to heel and toe without uncomfortable contortions.

The pre-1974 911s are not fitted with a brake servo. While this leads to much greater pedal pressures it does remove one possible cause of a spongey pedal. As I had asked Tuthills to replace all of the flexible hoses, the system should be as good as it was going to be in standard form. Richard did try and talk me into their rally spec. braking system; its FIA approved and proven in countless Tuthill prepared cars. But at £1,000 a corner it was a big bill at this stage, especially as it looks as if the engine will be running in standard 140bhp form for some time longer. 

A key component of the Tuthills rally set up is an adjustable bias pedal box. Containing separate master cylinders for front and rear axles, this replaces the (possibly 40 years old...) original Porsche component with two moderns items, adds some nice braided hose, and would also let me adjust the pedal position a little as well. The front/rear balance is changed using a neat dash mounted knob. 

It seemed a good solution, so supply&fit was added to Tuthill's job list, along with some updated Ferodo pads for the 'S' spec callipers already on the car.



Porsche's standard accelerator pedal is frankly a bit cheap and nasty. I'm sure it's made of the finest German plastics, but after 40 years of use mine was looking shiny, slippery and worn. And in spite of the brake pedal changes, I was still finding it hard to comfortably use the side of my foot to give a rev-matching 'blip' on down changes. 

In one of the Porsche mags I spied the neat answer, an alloy pedal made by D-Zug in the US. Patterned on the one used by Porsche in the 917, not only did it give me the adjustability I neede, but was also set more towards the vertical, bringing it closer the the brake. It looked just was I was after. The D-Zug team were a delight to deal with, and within a couple of weeks a pedal in anodised dark alloy was delivered to SS7 Towers. 

It was beautifully made, simple to install, and the only slight hiccup caused by the unusual (for a European) imperial Allen key sizes used for the pivot I was able to sort using an old key I found at the back of my tool chest. 

The result is good pedal feel and perfect spacing for my size 10's. 

Oh, as an aside; I discovered sometime after placing my order with D-Zug that the well known Los Angeles based Porsche hot-rodder Magnus Walker uses their pedals in the fantastic cars he builds.
