afx Posted June 28, 2018 Share Posted June 28, 2018 (edited) The unassuming 911SC/RS with true Motorsports pedigree: Back in February, the Porsche Museum launched a YouTube video that covered the top five rarest factory models ever produced. In the video, Dieter Landenberger, manager of Porsche’s historical archives establishes the usual suspects of rare and limited production street legal models from Stuttgart. Towards the end of the video, Mr. Landenberger proceeds to pull the cover off of a very unassuming white 911 that looks much like a Porsche turbo, at first glance. In somewhat dramatic fashion, the first limited production 911 specifically built for Rally Sport is introduced to the world as the second rarest factory model in the eyes of experts at Porsche AG. This video has been viewed 782,905 times to date, yet the SC/RS has just recently popped into the conscious awareness of rarefied Porsche models over the last few years. Some of this recognition can be attributed to coverage in European Porsche magazines that inherently embrace rally sport and the SC/RS’s successful association with legendary Rothmans sponsorship. Another part can be associated to the recent popularity of the Safari Rally 911 builds that we see on social media being driven with no constraints in every imaginable off and on road scenario. And lastly, as more top tier Porsche collectors try to assemble complete 911 RS model collections, the SC/RS stands alone as the rarest Rennsport derivative apart from the original 911R. As such, we will take a closer look at this rare RS model with two examples that have lived completely different lives and have came through our sales department. A true homologation special: In 1984, the Porsche Motorsports department in Weissach built 20 examples of the SC/RS to satisfy the FIA’s Group B competition homologation rules.The SC/RS borrowed freely from the 911 RS/RSR lightweight construction methods from a decade earlier. Typical deletion of standard street parts and the addition of factory lightweight items helped produce an 911 with a curb weight of 2160 Ibs. That is approximately 1,000 pounds lighter than the 911SC street car at a price of $72,000 in 1984. Due to the extreme lightweight nature of the SC/RS, the 290 hp engine propelled the 911 to a record 0-60 time of 4.0 seconds, as tested in 1984 by Automotor magazine in Germany. Impressive facts and numbers no matter which generation of Porsche is up for debate. An exercise in power to weight ratio: In true Rennsport deletion style, the SC/RS was an extreme example of a weight loss program.Deletions included: Rear seats Power window system Radio, speakers and SC heating system Hood springs and brackets Clock Heat exchangers Glove box door Door pockets FIA “Gruppe B” Porsche rally substitution SCRS parts: Lightweight body shell Aluminum hood, rear engine deck lid, door panels, and front hood prop. Aluminum six point “Matter” safety roll cage with removable door bars. Type 935 Recaro Racing seats “Glaverbal” lightweight glass Fibreglass/Kevlar front and rear bumpers Front aluminum skid plate (bolt on) Rear aluminum skid plate (bolt on) Full belly pan Fabricated aluminum gas heater protective cover Factory 3 point rally seat belt passenger side, 5 point racing belts on driver’s side FIA rear wheel gravel guards Factory front tower strut brace 80 liter fuel tank with mini-spare inclusion 917/930 turbo derived brakes RSR type hand fabricated exhaust system 7 & 8′ Alloy Fuchs road wheels Adjustable Bilstein struts plus coil-overs Front brake cold air system Hydraulic hand brake system with control valve Eberspacher gasoline heater 180 MPH (300 km/hr) speedometer External & internal “battery off” master switches Pair of “Oscar” hood- mounted rally lights (optional) Turbo 930 rear wing Heavy duty torsion and anti-sway bars 3.0 liter 290 hp engine with 10.3:1 compression with Bosh/Kugelfisher mechanical injection and dry-sump lubrication Engine oil cooler system Custom rally air cleaner system with central port conical filter housing 915/71 Transaxle with cooler, RSR clutch, close ratio gears and 40% limited slip deferential The Matsuda Collection SC/RS VIN# 018 VIN #018 is one of the last SC/RS’s to leave the Porsche factory in 1984. It was sold to Japanese industrialist, Yoshiho Matsuda, and put on display in the “Porsche Museum of Japan: Matsuda Collection”. It was never rallied and was displayed among seventy other Porsche’s for about fifteen years. It was occasionally exercised on a close circuit track in order to keep the mechanical systems in healthy order. Since then, it has been featured in four different international Porsche Collections. As it sits, #018 currently has covered 1,700 kilometers and is one of three most original examples left in the world. Rothmans team car SC/RS VIN# 008 Only six SC/RS 911’s had the back door factory support of Porsche and the checkbook that only Rothmans could provide in order to be competitive on the world stage, all under the direction of Sir David Richards and his Prodrive team. Prodrive manufactured many of their own Bespoke parts for the SC/RS and also added chassis reinforcement bracing to each chassis. Chassis #008 is known as a survivor and remains in its original, un-restored condition. It is equipped with an original Rothmans/Richards Porsche engine #63E09004 – the engine that Toivonen used in this car to win at Ypres, Belgium. This particular SC/RS, ran 13 international rallies for the Rothmans Porsche team. It won five of those out right (full competition record is below.) With endurance and rally veterans – such as Henri Toivonen, Juha Kankkunen, and Saeed Al Hajiri – at the wheel, this particular car became the one all the others chased. As Jurgen Barth described the driving experience, he explained, “The RS proved to be very controllable even at the handling limit. With coordinated throttle and steering, it could be driven on a very tight line, without resorting to such spectacular drift angles as its indirect predecessors. The potential of this sports car could best be experienced on closed roads – and that, after all, was its intended purpose.” The 20 SC/RS cars rival the 1967/68 Typ 911R in rarity and mystique. Chassis #008 and #018 have lived divergent lives, but stand as testaments of pure design and Motorsports execution. In the end, the SC/RS represents the most custom built RS derivative ever built by Porsche. Is it as well known as some of the other 911 RS iconic derivatives, like the 1973 Porsche 2.7 RS or 2012 GT3 RS 4.0? No, it is not. But will it always be one of the most special 911’s ever built by Porsche, most certainly.SC/RS VIN# 0018 Competition history: April 1984: Circuit of Ireland Rally, Ireland. Henri Toivonen, DNF.

iamsuperdan Posted June 28, 2018 Share Posted June 28, 2018 As a longtime Porsche fan, I'll be watching. The RS cars are my favourite of all the Porsches. The ultimate dream car for me is a 964 RS, a little newer than this one, but of the same spirit. Quote Link to comment Share on other sites More sharing options...

afx Posted July 1, 2018 Author Share Posted July 1, 2018 (edited) Thanks Joe. Ever have one of those projects you think will be simple but turns out to be anything but? The rear wing one of those. I needed the deep undercut of the '76 Turbo wing (far left) and the intake grille and opening of the '85 Turbo (far right). The modified SCRS wing is in the middle. Consumed (2) '85 wings, (1) '76 wing and a few brain cells but very pleased with how it turned out. Edited July 2, 2018 by afx Quote Link to comment Share on other sites More sharing options...

Matt Bacon Posted July 3, 2018 Share Posted July 3, 2018 In case anyone reading this gets a Singer itch they need to scratch, it's worth knowing that Scaleproduction does the clever Singer fold-down rear wing in resin to fit a couple of different base kits... best, M.

I've seen the Singer wings on SP's website Matt - thanks for calling it out however. Been noticing a rash, could be Singer related, that I may have to address.

I've definitely caught the bug: I even bought the SP '73 RSR specifically for the body of a Singer build (I got a nice email from a lady at Singer saying that although, no, she couldn't give me scale drawings or 3D model files for their cars, and that the Singer is not EXACTLY like any other Porsche body, the 73 RSR was the inspiration for the look, and is the closest.) Just a shame it's only available as a "not cheap" resin transkit! best, M. Quote Link to comment Share on other sites More sharing options...
