    911R prototypes

    This subject popped up in another thread. According to Paternie's little red book there were 3 911R prototypes based on 67 cars, 307670/1 and 305876, the rest had 68 VINs:

    If memory serves, the "silver weenie" was a '67...pretty rare bird indeed. It raced in the '67 (I think) Sebring race, Gary Wright at the wheel... Alan Johnson won in a sister car...I might be off on the year, but remember Gary telling me of a fading engine costing him the race, later backed up by reading a letter written by Terry B., who managed Porsche Cars Northwest...I'll post the pic again here...I think these cars deserve a seperate thread...

    PWD72 (et al):

    Was this "silver weenie" an all-steel car?

    If not... how much of it (bumpers, hood, etc) was fiberglass?? I'm just curious as to the mix of fiberglass and steel on this obviously a "non-911R" configuration. How about the engine...any specs available?

    A related question to all: Were the early "rally" cars all steel as well? how about any fiberglass/steel mix on those?

    cheers

    All the later Porsche rally cars I have seen were all steel (they needed to be for strength). The 1969 Tour de Corse (which was more of a race) 911R was a lightweight car. These had GRP front wings, bumpers, top and bottom of dashboard, tail light assemblies, front lid and engine cover. Some doors were GRP, some aluminium.

    There were actually 4 prototypes built in addition to the 20 'production' models.

    I have personally witnessed the ground-up restoration of prototype #3 & have provided Ernie Wilberg with detailed pictures of both prototypes #3 & #4 for display on his excellent website:

    I'm sure it won't be long before Ernie chimes in here...

    As far as I know, the silver weenie was all steel. But as it's race carreer went on, things "evolved"...as race cars tend to do. For example, I believe that is 2.0 engine "evolved" into a 2.5 by the time it ran it's last race...also, I don't think the term "prototype" was used when it was built, but could be wrong here..

    Were any of the "R"s converted to "S"s?

    My old mechanic in Miami said he bought one from Brumos in the late 60s and it had started off as a race car and then converted to an S. I never saw the car, but I remember him telling me about it. I think he passed away in the last 10 years.

    Again, scanned from my bookshelves. I don't know if the word "prototype" is the term ze engineers at ze fectory used to describe the experimental lightweight precursers to the O-ficial 911R. But they did exist-
