Classic Retrofit Porsche 993 R&D

Classic Retrofit Porsche 993 R&D

Jonny Hart at Classic Retrofit picked up a pre-Varioram Porsche 993 Carrera 2 Tiptronic Coupe through some trade friends last August. I’ve often thought about using a 993 as a daily driver and I know many of you actually have. it’s been fun to see what Jonny has made of the 993, and how much he has used it when there is also a nicely restored 911 SC, an electric 914 and an electric works van in the fleet.

“Work on the 993 has included an overdue service, a front end strip and rebuild and of course we’re using the 993 as a development vehicle and test mule for our next-generation Porsche electric air conditioning systems,” he says.

“As this car was never fitted with air conditioning, we’ve fitted our full system including our upgraded alternator. This is a harder installation on a Tiptronic as it has an additional transmission oil cooler up front so a second condenser is not possible. Instead, we’re trialling a new-tech version of our single condenser setup.

“Made by a Dutch company, the new condenser is 50% more efficient than the original 964/993 condenser, which is a big improvement. While we have been using twin condenser systems which give massive headroom over the original, a 50% improvement on the original part is more than enough for most users, especially when combined with our new CCU, which is also in testing in our 993.

“Other improvements seen on the test mule include the development of a tightly-packaged combined battery and A/C Compressor mount to minimise the space required by our electric A/C system: watch out for this as a new product. One more product developed for the car is a replacement tweeter mount to fit Focal FN43 tweeters into standard Porsche 993 door cards. This is a great little upgrade for audiophiles and is available to buy now.”

Jonny says that recent road trips to Retromobile in Paris and visits to several UK consultancy clients have shown that, some 30 years after its introduction, the 993 remains a highly capable and comfortable daily driver. While the Tiptronic is relaxing most of the time, the car can still get a shift on when needed. I might need to borrow this one of the days.

New Guy Allen Porsche Art Notebooks

New Guy Allen Porsche Art Notebooks

The key to an enjoyable freelance career is realising one’s most exciting ideas. Saving ideas – good or bad – for future reference is crucial, and a solid notebook habit soon becomes one of the most important practices in a freelancer’s life.

A notebook is not just a writing space: it is also a thinking space. My pile of colourful A5 moleskine notebooks dates back to the mid-2000s, when I first starting writing about Porsche. Their contents are interwoven with several thousand voice memos and tens of thousands of iPhone images shot over the last twenty years.

I therefore regard my notebooks with great affection and appropriate respect and so I was delighted to get an email from my friend Guy Allen last week about a new range of notebooks he has designed in collaboration with German publisher, Dingwort Verlag.

The A5 notebooks contain 176 pages of sustainably sourced 120gsm Munken paper, with a subtle dot grid printed on each page. The recycled leather covers are screenprinted with some of Guy’s most iconic print designs. The covers have a soft-touch coating and a smooth textural finish. Solid thread stitching and a round spine allow the books to lie flat when open. Rounded corners and black edges help to protect against wear and tear.

Guy sent me a notebook to experience the quality. He chose to send his 911 print – one of my favourites and in my Guy Allen collection. It arrived just in time, as I was on the last two pages of my most recent notebook, so today is my first day using this one. My Lamy Al-Star workpens seem to agree with the very beautiful paper and I have several big classic car valuation reports to get through this week, so I will enjoy filling this with thoughts, ideas and conversation notes and whatever else sparks my awareness.

The Guy Allen Art notebooks are available to buy direct from Dingwort Verlag and no doubt they can ship in time for Christmas. I am tempted to add the Col de Turini and Salzburg 917 designs to an order. Guy’s work is beautiful, so I am delighted by the prospect of having it in my hands and on my desk every day.

Rare Air at Saratoga Springs

Rare Air at Saratoga Springs

The beautiful Porsche collection of Steven Harris is about to go on show at the Saratoga Automobile Museum in Saratoga Springs, New York. Running through to autumn 2021, the exhibition includes many significant models in original factory condition, but also some cars that were modified to match the owner’s intentions. The list of air-cooled Porsches on show includes:

  • 1956 356A Carrera Coupe
  • 1957 356A Carrera Speedster
  • 1958 356A Carrera GT Coupe
  • 1959 Carrera GS Cabriolet
  • 1960 356B T5 Roadster
  • 1963 Carrera 2 GS Cabriolet
  • 1964 356C Couple – Peking to Paris Rally car
  • 1973 911T “SHTang”/RGruppe
  • 1973 911 Carrera RS
  • 1974 911 Carrera RS 3.0
  • 1984 911 SCRS
  • 1992 964 911 Carrera RS Lightweight
  • 1992 964 911 RS N-GT “Macau”
  • 1994 964 911 RS 3.8
  • 1995 993 911 Carrera RS
  • 1995 993 911 GT2

As part of the exhibition’s preparations, my long-time friend and creative partner, James Lipman, flew to NY and shot the collection in studio, for an accompanying book that will document the collection at this moment in time. The photos seen here are by James.

Steven was responsible for introducing James to the profound effects of immersion in the social scene that surrounds air-cooled Porsche life across North America, particularly in California, where the light hits just right. James’ enthusiasm for a trip to the Baja California taken with Steven sometime in early 2009, and the wonderful images that came out of that trip, led to his selling me on the idea of doing some work out there in May of that year. This was our first R Gruppe Treffen, where we shot the two SWB 911s of Bob Tilton and Chris Nielsen that inspired a raft of work over the next two years and forged lifelong friendships.

Steven’s formative influence does not end there. An esteemed career in architecture has included professorships at Harvard, Yale and Princeton and the work of Steven Harris Architects LLP may be seen all over the world. It is my privilege to have stayed in Steven’s own house in upstate NY and to have briefly experienced what it is to exist inside the vision of a professional whose work I greatly admire.

Combining an achitectural vision with a deep understanding of air-cooled Porsche culture and history (not to mention a keen awareness of market activity) has created to the collection that is partly shown at Saratoga, including several Amelia Island Concours d’Elegance winners. I urge anyone local to the museum to visit and experience Steven’s cognitive precision as expressed through his collection, and to enjoy what blending true passion for these cars and a genetic understanding of what great design looks like can accomplish over time.

New Bids on the Block

New Bids on the Block

The online classic car auction scene has taken off since the first lockdown and I’ve been kept busy inspecting auction cars for sale, including all sorts of classic cars offered through On The Market and Collecting Cars. Now there’s a new online auction seller – Manor Park Classics – whose first sale on April 27th includes a pair of longhood Porsche 911 Targas.

I don’t know much about Manor Park Classics, but their web content appears to be the polar opposite of my taste in content, so it’s no surprise that the name is new to me. The debut auction currently stands at 137 lots: five motorcycles, various items of automobilia and number plates and around 92 cars if my maths is correct.

The sale includes several lots from the Vauxhall Heritage Collection, which will be offered at no reserve, including nice examples of basic Vauxhalls such as the Nova and original Viva. The other lots run the gamut, from Bentleys and Rolls-Royce to low mileage Jaguar XJS, several MGs and classic Minis and a handful of other run-of-the-mill bits and pieces that caught my eye, including a low-ish mile E28 520 at a fairly chunky guide price of £8-10k. I had quite a few E28s back in the day and I do love these cars. My mother began her driving career in a 1974 Renault 6 similar to the LHD 1972 example on offer with another perhaps optimistic guide of £5-6k, but we’ll see how that one does.

The first Porsche for sale is a 1973 RHD Porsche 911 E Targa in Gold, retaining its original tan leather trim but with a recent engine and gearbox rebuild costing some £8.5k. This is a decent engine out service on an MFI car atsome specialists so it is worth knowing what this rebuild entails. The 911 2.4E is my favourite longhood variant so that is a positive if the rest is up to scratch. Auction cars rarely are, so inspect things carefully before bidding.

The other 911 for sale at auction is a 1967 LHD Porsche 911 2.0 Soft-Window Targa in Golf Blue with black trim. In the UK since 1999, this car appears to be quite a good example, having come from its original owner with a huge pile of provenance and offered with body restoration bills for over £21k in the last few years. No mention of who this was with or what panels were replaced and that is important to know. Guide on the soft-window Targa is £90-110k. Bear in mind that there is a 15% Buyers Premium payable on all bids.

Robots seal the deal in Stuttgart

Robots seal the deal in Stuttgart

Porsche is replacing the need for paint shop workers on the Taycan production line to insert up to 100 plugs on every car after paint and sealing wax with a robotic process of sealing all cavities with robot-applied patches.

Porsche’s partner in the new process is Tesa, a leading supplier of office tape and a typo away from those other electric car people – I wonder what Google searches will make of that. The patches are highly durable and protrude only 1mm from the surface, versus 6mm for the plugs that were previously employed.

Porsches says that its workers have previously had to insert up to 3,600 plugs per shift, so at 100 plugs per car that is 36 cars per shift. If each shift is eight hours, that is 108 cars a day. It is slightly mind-blowing to imagine the sight of and logistics behind 100 cars a day rolling off the Taycan production lines and being moved to new owners all over the world. Anything Porsche can do to speed up the build process and reduce stress on its workers will be a welcome addition.

“At Tesa, we incorporated more than 20 years’ experience in the manual adhesion of sealing patches in assembly to the development of the Tesa applicator for automated hole sealing,” explains Dr Ute Ellringmann, Market Segment Manager responsible for hole sealing at Tesa. “We can therefore ensure perfect application of our sealing patches for maximum quality and process efficiency.”

“Innovation has always been the driver of our commercial success,” says Albrecht Reimold, Member of the Executive Board responsible for Production and Logistics at Porsche AG. “New innovations have to be mastered. This requires courage and creative freedom. It is management’s role to ensure that this atmosphere is fostered in the day-to-day operations of the company.”

The all-electric Porsche Taycan is the first car in the world to use this new process. Porsche Innovation Management supervised the adoption of the sealing patches, and by July 2020 more than two thirds of the approximately 150 plugs in the Taycan paint shop had been eliminated. The paint shop at the Leipzig plant will also make the switch by summer 2021.

So much to digest here, including the fact that Porsche has an Innovation Management team. This is something worth learning more about – how does a business that innovates everywhere manage that and harvest innovations in one place to use in another? Rolling innovations that take shape in one part of my tiny business out across the full spread of what I do takes months for me – would love to know how Porsche manages this. I think Stuttgart’s innovation management strategy and processes may be the real story here.

R Gruppe Porsche 911 for sale (now SOLD)

R Gruppe Porsche 911 for sale (now SOLD)

It was good to hear from many R Gruppe friends after my recent post on the late Cris Huergas. One name that popped up in my inbox was Hayden Burvill at WEVO, who is about to put his 1972 Porsche 911 up for sale.

The car in question is Kenny: a 1972 911T built in May of that year and finished in rare Gulf Orange. The ‘oil klapper’ side oil-flap 911 now runs a 2.4S engine, rebuilt by Jerry Woods, but the matching numbers engine comes with the car.

Kenny has been owned by a handful Porsche enthusiasts in San Francisco’s Bay Area since it was new in 1972. It’s the car that inspired the Aussie engineer and product designer to begin modifying 911s – initially for autocross competitions – and develop a range of chassis and drivetrain products to sharpen the air-cooled 911 driving experience.

Products developed on Kenny include the famous WEVO shifters, engine and transmission mounts, anti-roll bars and suspension parts. Kenny is also fitted with several prototype parts that never went into production, such as the WEVO brakes that I vaguely attempted to buy several times but could never convince him to sell.

The WEVO brakes remained in prototype due to projected retail price against the value of air-cooled cars at the time. The numbers would probably make more sense nowadays, but life has moved on and there are other products out there. Hayden instead developed his 5-speed conversion for Porsche 356 models and that has been going well since launch.

Kenny has been part of my world since 2008, when I took my first trip out to San Carlos to meet Hayden and Tracey at WEVO. They could not have been more welcoming and our friendship continued when Twinspark Racing became WEVO’s official European distributors. I was a partner in Twinspark at the time, along with my friends Leonard Stolk and Lex Proper, so we did a fair amount of business together.

Hayden’s exploits in historic rallying on events like the Peking to Paris alongside Steven Harris and more recent rallies with Alastair Caldwell have kept us in touch. Our last time together in person was when Ciara and I joined H and the EB Motorsport guys for dinner on the beach at Zandvoort after the Masters Historic Grand Prix in 2018. Great times.

The world has turned on its head in two years and the pandemic has shifted life goals for both of us. Hayden’s responding by selling some cars and doubling down on a sustainable lifestyle. His 993 daily driver has already departed and Kenny is next on the block. The cool blue 912 is also likely to go.

Long-time followers will remember our feature on Kenny, which ran in one of the Porsche magazines back in the day. Jamie and I took the car to Pacific Grove near Monterey before sunrise and shot it on the coast as the sun came up. It was an unforgettable experience.

I’ve driven a lot of miles in this car, incuding down through the redwoods from San Francisco to Laguna Seca (above), where the car has seen many great days on track. As Hayden was an early R Gruppe member, Kenny was one of the earliest R Gruppe cars, attending all sorts of group events over the years. There is an air of authenticity about this one that later R Gruppe creations can’t hope to match. The aim is to place it with someone who will appreciate the history and keep piling the miles on, enjoying the car while we are still allowed to drive them.

Hayden wrote up a great spec on the 911 and you can download a pdf of that here. I’ll put the main points below. This is a special 911 with room for cosmetic detailing if you want to go that way. I would probably just run it as-is (with one of Jonny’s electric air conditioning kits, of course).

1972 Porsche 911 for sale – Specification

Engine

That original engine was replaced by the current engine, a 2.4-litre MFI engine from a 911S that was dressed using the original yellow “T” fan shroud and a combination of 2.4S intake system, recalibrated MFI pump and the highly regarded Elgin “Mod-S” camshaft grind. The engine made ~195hp at 6750rpm on the Jerry woods dyno with airbox, filter and Abarth muffler installed.

The engine was detailed when it was installed in 2004 and the installation is otherwise stock. There is no external oil cooler, it has the stock MFI fuel pump mounted in stock location, stock fuel filter and fuel cut-off valve all mounted and functioning.

WEVO SS engine mounts are fitted. The current exhaust is stock MFI heat exchangers (cabin heat connected) and a stock MFI muffler with the period correct ribbed outlet. The accessory package that comes with this car includes a rare Abarth 4-outlet muffler, an equally rare and unique 6-outlet muffler (for when 4 is not enough!) and a rare, unused 2 x 2 muffler with a pair of chrome outlets exiting wide; one on each corner of the rear bumper.

The engine has a WEVO 915 Streetlite Clutch kit using a spring-centre friction disc. The low inertia and added performance of this clutch kit is especially noticeable at full throttle in second and third gears.

Transmission

As one would expect given WEVO’s unique expertise, the transmission has been through a variety of revisions, at times running a WEVO super lightweight spool instead of an open differential. It currently has a Porsche factory ZF limited slip differential. It has a very deliberate build suited for easy street driving, or aggressive track driving. 80% build configuration giving the maximum friction surfaces, then carefully shimmed to have a very light pre-load of only 10 ft/lbs.

This configuration gives a high locking action during aggressive driving and easy rolling and steering at low speeds. The transmission has a suite of WEVO products, including XT 100 Side Cover, WEVO 915 GateShift kit and XT 032 bearing retainer plate. The gearbox is in great operating condition and needs no repairs.

Interior

Hayden’s interior spec goes into quite a lot of detail but, in short:

  • Fitted factory sports seats
  • Abarth 360mm sports steering wheel
  • WEVO 915 shifter with +40mm lever (my 911 also has this: perfect mod)
  • WEVO PSJ shift coupler and XT 147 clamp
  • Accessories package includes bespoke carbon fibre seats with custom rear cage

Bodywork

Again H has added a lot of detail to the bodywork section. In summary:

  • Sunroof 911 finished in original Gulf Orange
  • Rust-free car that has lived in California for almost fifty years
  • Distinctive WEVO-logo graphics
  • Presented as RS with SC/Carrera rear arches
  • Fibreglass bumpers and ducktail
  • Bespoke front brake cooling ducts
  • H1 headlights with Euro rear lenses
  • Accessories package includes original steel rear bumper and deck lid, and an early S steel front bumper

Suspension

See the full pdf for details of this. One could hardly ask for a better suspension setup on a sports-purpose early car:

  • 21/26 torsion bars
  • RSR raised-spindle front struts with Bilstein inserts
  • WEVO Camberking top mounts with Teflon monoballs and carbon fibre cross tube/strut brace
  • Weltmeister 19mm front ARB
  • WEVO Spring Plate system rear end (now unobtanium)
  • ’76 trailing arms with SRP monoballs and WEVO E-Z pins
  • Weltmeister adjustable rear ARB
  • Koni adjustable rear dampers
  • SC CV joints in stock driveshafts

Brakes

Highlights include:

  • Aforementioned WEVO prototype billet aluminium calipers
  • Designed to fit inside 6×15 wheels with a nod to 930 brake performance
  • 315 x 28mm front brake disc
  • standard 930 rear disc with handbrake bell
  • 930 pads for ease of replacement
  • Accessory package includes set of new discs and all brake servicing literature

Wheels and Tyres

Kenny runs on nicely restored 7 & 8×15″ Fuchs, with Avon CR6ZZ Classic 185/70 front and 215/60 rear tyres. The spare is a 6 x 15″ Fuchs with a 185/70 tyre.

Enquiries and Price

It can be difficult to price cars like this and would be all too easy to get that wrong. Setting the mods aside, we have a low-owner ’72 oil flap 911T with sunroof in a relatively rare colour with a matching numbers engine and the original panels ready to be refitted. The only major change is the SC arches.

Adding in the mods we have a Jerry Woods 2.4S MFI engine making circa 200 horsepower, custom WEVO transmission with pretty much everything you could pick from the catalogue, custom suspension, custom brakes, simple but desirable period trim that one could improve and so on. It also comes with a ton of additional parts, including the original engine.

The key to this car for me is that it is not fake. It is not a poser. It was forged at the centre of air-cooled 911 culture and has been driven and developed over twenty years of ownership. What was created specifically for this car may now be found on thousands of 911s all over the world. But there is only one original. Does that story add any value? Well, the buyers will decide. What price romance nowadays?!

So to the price. Hayden is open to offers circa $150,000, which is £114,000 or €126,000. To find a similar rust-free 1972 911 and fit it with an S engine with the WEVO bits one can still buy would easily exceed this. And that car would not be built by WEVO. Add in the unobtanium, the spares bits and who knows what else the boss will include and you have a unique piece of air-cooled history.

The car is located in San Francisco, but can of course be shipped anywhere in the world. I am helping out with this one should it make its way across the pond to the UK or Europe, so you can contact Hayden via WEVO.com or drop me a line – john@johndglynn.com – or give me a call on +44 7565 348453.
