 Almost the forgotten Porsche now , the entry-level new

Porsche for the 70s had a remarkable succesfull racing

life. Debuted in April 1970 and several existing 911 race

teams bought one which led to 7 2-litre GT class wins in

the 1970+71 seasons ( see box below ). Teams like Max

Moritz , Squadra Tartaruga , Romand and Eugene Strahl

campaigned them in Europe. Other continued racing in

national GT events until around 1977.

America was a big export market and by the November    

of 1970 nine customer cars contested the Road Atlanta

champions race including Peter Gregg in the Brumos car

as several Porsche dealerships ran race teams. The car

would have a particularly long US career in IMSA GTU

racing until the mid-80`s. Its Daytona 24 record , some

in the World Championship some just the IMSA opener

was 1971 ( 7th ) , 1972 (13th ), 1973 ( 19th ), 1975

( 18th ), 1976 ( 13th ) , 1977+78 ( DNF ), 1979 ( 7th),

1980 ( 5th ), 1981 ( 13th ), 1982 ( DNF ). Remarkable

finishes for a 2-litre car. The US teams evolved the

914 with wide whell arches and spoilers to keep up with

progress and the 1980 class win beating 6 Mazda RX-7

at Daytona was a suprise. Also raced in 13 Sebring 12

hour races.

 PORSCHE 911 CARRERA RSR  ( group 4 )

( Le Mans class wins 1973,74,75,76+78 )

ENGINE :   flat 6 Cylinders 2800 cc ( `73) , 2993 cc ( `74 )

POWER :    290 BHP  ( Le Mans 1973 )

WEIGHT :   945 to 985 KGS ( Le Mans 1974 )

TOP SPEED :

PRODUCTION :

 Won on its debut at the Daytona 24-hour race , February 1973 when

the factory loaned Brumos and Penske teams a car each with the new 2.8

engine. Peter Gregg and Hurley Haywood winning for Brumos. The 2

cars actually ran in Group 5 Sports as the homologation to Group 4 GT

didnt start until March 1st. The pair repeated the win at Sebring ,

which unlike Daytona wasnt part of the world Championship that year

but at round 2 at Vallelunga and round 3 Dijon the new works car in

Martini livery won group 4 for Follmer/Kauhsen/Muller/Van Lennep.

By R4 Monza the  works cars returned to Group 5 as Motor Sport mag

explained. `The two Martini Racing works Carreras were ruled out of

GT due to having modified anchor points for the rear radius arms , so

the factory took advantage of being in the Prototype class and made

the rear aerofoil full width instead of the homologated engine-lid width`

So with the 2 works cars freightning the Ferrari and Matra sports cars

and indeed winning on the last world Championship Targa Florio it was

the customer teams , like Kremer to win the GT class in 5 of the

remaining 6 rounds , settling for 2nd in GT at Le Mans behind Ferrari.

The 1974 GT season was dominated by RSRs and the 2 red Georg Loos

`Polifac`cars won 6 rounds of 10. With the latest mods , such as a large

`tea tray`rear spoiler and vents in the wheel arches to cool the brakes.

Lead driver John Fitzpatrick won 5 of the world championship rounds.

RSRs won 9 rounds outrite in GT , only beaten outright at Le Mans.
