The Ex-Hartwig Bertrams, Tebernum Team European GT Championship/Amalfitano Collection
1975 Porsche Carrera RSR 3.0 Carrera Competition Coupe
Chassis no. 911 560 9121
The historic Porsche RSR Carrera Coupe requires little introduction to such an experienced market. Amongst this most thrilling, attractive and today still widely useable series of competition cars this particular example chassis '9121' is one of the last 'customer' 3.0 RSRs manufactured by Porsche for the 1975 racing season.
There is a letter to a former owner, Mr Robert J. Luth of Darien, CT, dated November 10, 1983, in which the respected authority Jurgen Barth of the Porsche factory's Sport Department writes: "As to your 1975 RSR serial 9115609121 we searched in our files and can now give you the following information. The car was first delivered to Hartwig Bertrams. He most probably won the GT European Championship with this car." This letter also states that the car was fitted originally with engine no. 784 0167.

We understand that for the 1976 racing season the Tebernum Team combined with Georg Loos' Gelo Racing organization. Unfortunately accurate records do not exist to establish the individual chassis histories of the Gelo Racing Team RSRs, of which there were several. However, it is likely that this RSR was raced under the Gelo banner subsequent to the consolidation of the two racing teams.
This well raced and very successful Porsche 911 RSR was subsequently sold to the United States and in the early 1980's was obtained by respected specialist Ron Armour of Orange, California. A complete restoration was undertaken by Mr Armour with careful attention to the original RSR body panels. Work was completed in time for this famous RSR to compete in the 9th Annual Monterey Historic Automobile Races of which Porsche was the featured marque. As the only 911 RSR to be accepted, both the RSR and Mr. Armour performed well, especially considering the caliber of the cars in the run group.
Eventually the RSR was sold to Mr Bob Luth. The car was then acquired from Mr Luth by the late Michael Amalfitano in February 2002. Documentation is also preserved within the file accompanying this Lot recording engine work carried out by Andial Road & Racing of Santa Ana, California, during 1995, for which the bill totalled some $20,725. An FIA Historic Vehicle Identity Form is also offered, issued to the Amalfitano Collection in November 2002 by the World governing body's American affiliate, ACCUS, and covering this car, listing date of restoration as having been 1985. An engine test dyno run dated February 14, 1998, is also appended in which engine power output was recorded as 318.6bhp at 6,900rpm, allied to an average torque of 243ft/lbs.
As presently offered here this prime example GT-category endurance racing Porsche 911 RSR is in recently re-assembled condition, its engine having been rebuilt and freshly dyno tested as recently as last month, 2010. The power unit has been completely restored, all items crack tested, the engine equipped with new bearings, new fiberglass shrouds, new exhaust, the injector pump serviced by Bosch Germany, with great detail attention paid to all additional small parts, hardware, etc. We are advised by Amalfi Racing's well-known chief mechanic Klaus Fischer that "...this engine is pure RSR, it has the correct cylinder head stud spacing with original cylinders, also the cylinder heads are dated 1973/1974, completely rebuilt. The block is the proper type aluminum specification, valve covers are magnesium. Rocker arm shafts are solid (good for 8,000 rpm and above). The upper intake is, as it should be, sliders. During the 2001 Le Mans preparation we installed a set of original RSR cams. Everything else matches RSR specification apart from the ignition system which is MSD and not Bosch...". A dyno test performed as recently as July of this year recorded the output of the current motor at 300 bhp at 7,500rpm.
In addition, this Porsche RSR's gearing is set up for the Sarthe circuit at Le Mans, France (intended for competition in the Le Mans Classic event) . It was completely overhauled in 2001 with all new gears and ring-and-pinion. Mike Amalfitano did not in fact attend the Le Mans Classic and the car has covered very little mileage since that work was completed.
The Porsche RSR is the defining competition model and the ultimate 911 variant for many Porsche enthusiasts worldwide. Here we offer a fine example with impressive provenance, awaiting its return to historic competition in the hands of a new owner.
