Porsche Rennsport Reunion VI - Can-Am and Interserie

Porsche 917/10s attack the Corkscrew at Laguna Seca agin.

There were lots of reminders at Porsche Rennsport Reunion VI of Porsche's success in Group 7 via Can-Am and Interseries.  Laguna Seca is of course an appropriate place to bring these cars to as it held rounds of the original Can-Am series from 1966 to 1973.   Porsche won the last two Can-Am events at Laguna Seca - George Follmer in 1972 in a 917/10 and Mark Donohue in 1973 in a 917/30.

Each day at RRVI the Porsche 917/10s and 917/30s did exhibition runs.

Strangely enough, although Porsche ended dominating the Canadian-American Challenge Cup as it was properly known, their first win was a giant killing act.  The occasion was the 1970 round at Road Atlanta.  The big boys all hit trouble but Tony Dean's privateer Porsche 908/2 ran reliably and fast and took the win.  It was the first time in 19 races that the all conquering McLaren team had been beaten!   Tony Dean went on to finish sixth in the Championship.

From 1969 to 1974 the Watkins Glen Can-Am round was run as a double header with the World Championship 6 Hour endurance race.   Thus in 1970 and 1971 many Porsche 917Ks took the opportunity to enter the Can-Am round.  Jo Siffert, Richard Attwood and Vic Elford finished second, third and fourth respectively in 917Ks in 1970 at Watkins Glen.   Gijs Van Lennep and Brian Redman finished sixth and seventh, also in 917Ks.   Van Lennep was the highest 917K finisher in 1971 at Watkins Glen in ninth place.

We mustn't forget that the Porsche 917K was also a Can-Am car.

One of Porsche's first serious Can-Am efforts was in 1969 with the Porsche 917PA.   Although it didn't take any wins, Jo Siffert was to finish fourth in the 1969 Can-Am championship driving it.  Best result was a third place at Bridgehampton.   Milt Minter was to drive the car in 1971 finishing sixth in the championship and Sam Posey drove it in 1972.

Porsche's next serious Can-Am effort was in 1971 when Jo Siffert entered a STP sponsored Porsche in the series 917/10.  However, again he only finished fourth in the championship with two second places the best result.   With the 917 banned from endurance racing after 1971 it renewed its attack on the Can-am series with a revised 917/10 run by Roger Penske.   Thus in 1972 Porsche finally won the Can-am championship with George Follmer winning five our of the nine rounds in an L&M sponsored 917/10.  Mark Donohue also won a round and Milt Minter finished third in the championship in the Vasek Polak car.   McLaren had at last been beaten after dominating from 1967 to 1971.

The view that most competitors had of the car.

In 1973 Porsche gave Roger Penske the absurdly fast Porsche 917/30 to run in the Can-am series.  Mark Donohue drove the car and won the championship and took six wins in eight rounds.  This domination and the oil crisis pretty much killed off the series.

Whilst Mark Donohue was dominating upfront the 917/10s were fighting over second place.  Hurley Haywood finished third in the championship in the Brumos Racing 917/10 with one second place and two third places as his best results.  The car was at Laguna Seca as was Hurley Haywood.  They were reunited.

Some famous drivers were trying their hands in the Can Am cars at Laguna Seca.

Jochen Mass was driving the same car on Sunday but it broke down.

Interserie started in 1970 as a European version of Can-Am.  In 1970 it was dominated by the Porsche 917K.   In 1971 Leo Kinnunnen won in a Porsche 917 Spyder.  In 1972 and 1973 Leo won again but in a 917/10 against competition from Willy Kauhsen in a similar car.  The Willy Kauhsen Bosch sponsored car was at Laguna Seca.  It won two years running at Imola and also won two other Interserie races including 1974 at Silverstone.

Another Interserie Porsche 917/10 was the George Loos driven Gelo Racing Team car.  This was also at Laguna Seca.  It scored a number of second places.

Gijs Van Lennep won an Interserie race at Keimola in 1970 in a Porsche 917K and scored Can Am points in two consecutive years at Watkins Glen also in a 917K.
Willy Kauhsen drove a Porsche 917/10 in both the Can Am and Interserie championships.  He had four Interserie wins to his credit in the 917/10 and his best result in Can Am was an eighth place.
Hurley Haywood drove a 917/10 in Can-Am in 1973 and 1974.  Best result was second at Riverside in 1973.
Vic Elford scored the first win for the 917/30 at a Interserie race at Hockenheim in July 1973.
Brian Redman drove a couple of Can Am races in 1973 for Vasek Polak in a 917/30 but didn't finish either race.  In 1974 in drove one Can Am race for Roger Penske in a 917/30 finishing second at Mid Ohio.
