1970 Daytona 24 hour race
The fifth Daytona 24-hour race , also the Ninth Annual World's Championship 24 Hours of Daytona International Road Race, Daytona International Speedway, Daytona Beach, Florida , took place on February 1 and 2, 1970 at Daytona International Speedway and was the first race of the sports car world championship this year.
Before the race
1970 began the collaboration between the Porsche racing department and John Wyer Automotive , John Wyer’s team . Two weeks after the end of the sports car world championship in 1969 , the team was invited to test drives with the Porsche 917 . The test took place at the Österreichring , where the 1000 km race in Zeltweg was held 14 days earlier , in which two Porsche 917s met the Mirage M3 from Wyer. Wyer had traveled with the entire management team - David Yorke , Ermanno Cuoghi , Peter Davies and John Horsman - and extensively tested the car under the direction of Porsche technicians Peter Falk and Helmut Flegl . The tests were driven by Porsche works drivers Kurt Ahrens , Leo Kinnunen and Brian Redman, as well as by Piers Courage , who was hoping to get involved with Wyer. It was the decisive test for the Porsche 917, where John Horsman attached a wide plate to the rear of the racing car (similar to a Gurney Flap , only larger) and thus finally solved the aerodynamic problems on the vehicle. The contract between Porsche and Wyer included the use of two cars for the entire season and the takeover of the two Porsche works drivers Jo Siffert and Brian Redman. Wyer was allowed to choose the other two pilots. Dream driver Jacky Ickx was not available after moving to Scuderia Ferrari . Conversely, Pedro Rodríguez left the Italian racing team after just one year and switched to BRM in Formula 1 . Rodríguez had already driven for Wyer and is now returning to the team. Fourth driver would be David Hobbs , who was part of the regular Wyer team. During a test in the fall, a gearshift error by Hobbs destroyed all of the valves in the V12 engine of a 917. Ferdinand Piëch was so upset about this that he insisted on replacing Hobbs. Wyer finally had to agree and accept Leo Kinnunen as the fourth driver
In 1969 the Porsche team had won the world championship at great expense. In 1970, alongside Wyer, the Porsche Salzburg team led by Louise Piëch took on the works outings. The contracts of a large number of the pilots were extended. Porsche was hit hard by the fatal accident of Gerhard Mitters . Mitter was for many years and works driver during practice for the Grand Prix of Germany in 1969 on a Formula 2 - BMW F269 is killed. His friend and team-mate Udo Schütz then announced his resignation. The only exit concerned Rolf Stommelen , who switched to Autodelta .
The race
Three Porsche 917s were at the start in Daytona. In addition to the two Wyer cars for Siffert / Redman and Rodríguez / Kinnunen, a Porsche Salzburg 917 for Kurt Ahrens and Vic Elford . The Ferrari 512S , the Scuderia's new emergency car, made its racing debut . Three of the new 5 liter racing cars were registered by Scuderia and entrusted to the driver teams Mario Andretti / Arturo Merzario , Jacky Ickx / Peter Schetty and Nino Vaccarella / Ignazio Giunti . Luigi Chinetti's North American Racing Team reported a fourth 512S for Dan Gurney and Chuck Parsons . The North American Ferrari team came to the race with a large crew. In addition to the 512S, there were two 312P coupes for Sam Posey / Mike Parkes (who made a comeback as a driver) and Tony Adamowicz / David Piper , a 250LM for Gregg Young and Luigi Chinetti junior , a Ferrari 275 GTB / C for Harley Cluxton / Gordon Tatum and a Ferrari 365 GTB / 4 for Ronnie Bucknum / Wilbur Pickett . The two wealthy Italians Corrado Manfredini and Giampiero Moretti drove another 512S .
Matra Sports reported two MS650s . While Jean-Pierre Beltoise and Henri Pescarolo received a completely new chassis, Jack Brabham and François Cevert were given the car with which Beltoise and Piers Courage finished fourth overall in the 1969 Le Mans 24 Hours . The Matra van had an accident on the way from New York City to Daytona Beach . The two cars were so badly damaged that a third chassis had to be flown in from Buenos Aires . The car with which Beltoise and Pescarolo had won the 1000 km race in Buenos Aires served as a part donor for the two damaged emergency vehicles.
The two Wyer-Porsche 917s dominated the race. From the start, Jo Siffert and Brian Redman led the team-mates in the car with starting number 1. After three hours of driving, Brian Redman had to pull into the pit to an unplanned stop with a puncture on the right rear and lost the lead to Leo Kinnunen. Detaching rubber parts of the tire had damaged parts of the body that had to be repaired poorly. The brake disc was also changed. Coupling problems arose during the night. After the first refueling stops of the two Wyer-Porsche 917s, the Ferrari 512S of Mario Andretti and Arturo Merzario briefly took first position in the race and was in second place for a long time during the night. This was lost to the Siffert / Redman Porsche due to a repair on the suspension in the last phase of the race.
The Gurney / Parsons-512S was long in third place in the overall ranking. After a collision while lapping - Chuck Parsons was behind the wheel - this car too had to contend with a loosening body. As with the Siffert / Redman 917, tape was used at every pit stop . A gearbox failure led to the failure of the car after 464 laps. In the end there was a double victory for John Wyer's team.
The many SCCA pit marshals who caused some chaos in the pits and often gave the teams contradicting instructions caused displeasure. During the race, some team bosses at Bill France senior complained that this approach did not meet the standards of international sports car races .
