1972 Porsche 911 – ‘73 RSR Brumos (Hurley Haywood Sebring winning) Tribute

1972 was a unique year for the Porsche 911 generation with the repositioned oil tank and external filler cap on the rear ¾ panel, known as the ‘Oil Klappers’. An engineering design to improve weight distribution for the ever so successful 911 chassis. The external oil flap, a rare and wonderful feature that quickly became a flaw to some owners, mistakenly filling with petrol! Resulting with Porsche to revert the design for the upcoming years. Today, the 1972 ‘Oil Klappers’ are extremely rare, one year production of the 911, which has become quite a collectable.

Das Fahrzeug im Detail

This RSR build is based on an original left hand drive 1972 911T (manufactured on 19th May 1972) for the American market – residing in sunny California. The 911T was then acquired to a collector in Japan where it was shipped from West to East and spent the most part of 30 years in Japan before its arrival in the UK (we will get to that shortly).

The 911T traded hands to Jun Sato, a Porsche collector and builder from Tokyo, Japan. Jun decided to breath a new sense of life and purpose into the ‘Oil Klapper’. A transformation to 2.8 RSR spec began to unfold, but this was to be something special, a tribute to what we may argue as the most iconic, unique and decorative 2.8 RSR of all time: The Brumos 1973 12hrs of Sebring winning 2.8 RSR, raced by Hurley Haywood, Peter Gregg & Dr Dave Helmick.

We did say this tribute is little special. Jun had a connection with the original Brumos car. At the time of build, the Sebring winning RSR was being maintained and stored in the UK. Jun travelled from Japan to the UK to meet the car and have a private viewing of the original RSR. During this time, he scanned the original RSR and captured key design details to accurately replicate for the ‘Oil Klapper’ build. This included all the Livery design (shape, colour, & sizes), also noting the RSR bubble arch profile, front bonnet fuel filler design and even down to the finite details like the age related patina from its racing past.

In 2015 the build was complete and by December 2017 the RSR arrived in the UK, where it has been truly loved and cherished by its custodian.

The RSR is a sight to view, a full blown 70s race car! However, the build is an improved version of the original, with a philosophy to handle and outperform a period RSR. Stripped out to save weight (as Porsche & Brumos did in period), a full welded cage (replicating the Sebring RSR design) fitted with ‘patinia’ effect to match the worn
in-race appearance. The interior was crafted by Simon Farrell @pf911interiors, with specific instructions to match the period black light weight RS/RSR carpet, source period RSR seats and a few period details. The work speaks for itself, an undiluted cockpit, beautifully simple but with a purpose for racing, no creature comforts here. Lastly, Schroth harnesses fitted to finish the period interior.

This car is destined for track and fast B roads. That said, is surprisingly tame, if you can handle the exhaust note, around town and cruising on the motorway. All the mechanicals overhauled with uprated parts, from the suspension which includes Bilstein RSR Coilovers, fully rose jointed, mono-ball top mounts, solid engine & gearbox mounts and RSR front & rear sway bars. Power is delivered aggressively by a racing spec 3.2 flat six with all new internals including high compression pistons, cams & lifters. A unique intake system normally found on Cup cars & a full Dansk RSR exhaust system helps the engine breath & run at optimal power. This combination creates some of the best air-cooled sounds known to man. Its loud, raw and angry.

Sticking to period tradition a rebuilt 915 gearbox with upgraded Wevo shifter makes shifting a joy, so precise and engaging. I see why so many people love the old school feel of a 915 box. A mechanical shifter that requires a driver to really concentrate about each up & down shift. Sensational.

With all the upgraded power, the braking system had a revamp, in the form of rebuilt 964 brakes (painted in RS mint green) with period cooling ducts provide the additional stopping power. Further, the RSR has a period ATL race fuel cell & competition battery with electric cut offs. Overall, it’s a recipe for a hot vintage racer with a net weight under a ton and peak power north of 300bhp. This is a real visceral driving experience, pure, undiluted with no driver aids. Go as fast into the corners as you dare, there is plenty of grip from the 11j rear Fuchs wrapped in period Michelin TB15 rubber.

This “RSR” is so special, an addiction to drive and even more to admire from distance, and witnessing everyone’s reactions to its aggressive presence & exhaust note is such a buzz.
