1971 Sebring 12 Hours – Race Profile

1971 Sebring 12 Hours – Race Profile Page Nine

Michael Keyser and Bruce Jennings bit the dust on lap 23 when their Toad Hall Racing Porsche 911S expired. I communicated with Keyser about his remembrances of the race and he responded with this:

“I don’t remember much about the race. I do remember we stayed at a motel on the right side of Route 27 headed south and right across from Lake Jackson.

It was my first time driving at Sebring and I was surprised how rough it was. At night practice I followed a car ahead of me who had gone off the circuit, thinking he knew where he was going…wrong. In the same practice, coming out of the Green Park Chicane, I guess I held up Jacky Ickx in the Ferrari 312P because he pulled alongside and slowed and shook his fist. A few years later when I got to know him I “reminded” him about that. “Who? Me??? I’d never do anything like that.” Right.

I started the race and on the first lap I had so much adrenaline pumping that my foot was jumping off the accelerator going down one of the runways. I had to hold my leg down with my right hand! I remember fighting with the #29 914/6 and then there was a big bang and I lost power. When I got back to the pits, there was a hole in the block and a lot of oil…and a badly bent titanium rod. End of story.”

Keyser and Jennings were soon followed behind the pit wall by the MGB of Jim Gammon and Dean Donley after their engine died. Before the checkered flag would be waved 22 more cars would suffer mechanical issues and fail to finish.

As the first hour of racing came to an end pit crews all along the front straight started getting ready for the first pit stop for their car. In the Gulf pits they had already determined what the fuel limits were on each car and each driver was told when to bring in the car. As a reminder to drivers a pit crew member was usually sent out to the pit wall to signal the driver with one word, “IN”.

Up in the pit box an observer saw the #1 Siffert 917 coming down the back straight and into turn 12. They shouted to the crew member at the pit wall that Siffert was coming so he could put up the signal which Siffert saw and signaled he had seen it.

The low-fuel light was already on and this worried Siffert but less than a lap awaited him. As luck would have it the car died after entering turn 10. For those of you who remember the old 5.2-mile circuit, turn 10 is the furthest point from the pits and at the tip of the almost mile long North/South runway.

Being out in the middle of nowhere was not lost on Siffert. Initially he decided to hoof it back to the pits for a can of fuel. However, at the last second, he decided to hitch a ride on the motorcycle of a corner marshal so off they went arriving at the paddock/pit area in short order.

This decision by Siffert has been second guessed for years because it was well known by all that, under these circumstances, a driver cannot accept assistance of any kind in getting back to the pits. To do so risked disqualification from the race. This is what happened to Stirling Moss in 1959 for doing the same exact thing. While the stewards didn’t disqualify Siffert they did penalize his car four laps. Added to that were the additional 19 laps lost before he got back to the car, now on foot, then fueling the car and driving it back to the pits for a fill-up. The failure of the stewards to disqualify Siffert did not set well with some Sebring veterans and suggestions of favoritism for big name drivers and teams was raised.

Both during and after the race the motoring press was critical of this “stupid mistake” and blamed Siffert for not pitting before he ran out of gas or blamed the pit crew for miscalculating how many laps could be run before refueling. Siffert’s use of a motorcycle to get back to the pits also came under harsh scrutiny. In the minds of many these actions may have cost the Gulf team the win.

In John Horsman’s 2006 book, Racing In The Rain, John Wyer’s chief engineer for the Gulf 917 team tried to explain what happened. According to him they had determined how many laps could be completed on the Sebring 5.2-mile circuit before they had to bring in the two 917s for refueling. These calculations were a result of their vast experience with both cars.


Siffert was told earlier to bring in his car on lap 26 and to remind him he was also signaled to do just that. Unfortunately, the car ran out of fuel after completing half of lap 26 and at the furthest point on the track from the pits.

After the race it was determined, by fuel consumption figures, that Siffert’s 917 consumed quite a bit more fuel per 100 kilometers than the other 917. Somewhere there had to be a leak so they ran numerous tests on the car and found nothing. They could only conclude that there “…was a fault in the metering unit, as no leaks could be found.”

  1. Hello Louis, Your 1971 Seabring race report is the best I’ve ever read. Qudos, on that. I was a sportscar racer starting in the early 1960s in a number of classes including HM, Osca SN 951. and then went sailing and went back into racing in A Sports in the 1990s in Floriida. I have plenty of time racing at Seabring. The point I want to make is your great report leaves out the lower displacement classes which I find to be disappointing. That said, your own racing background that makes you such a good reporter.

    1. My race profile reflects the research material I was able to collect. Sadly the newspapers and magazines of the time concentrated on the big name drivers and race teams and neglected the smaller cars and independents. Will try to do better research next time to see if I can correct this oversight.

  2. Lou,

    As usual, your writing skills are top notch. Your attention to detail is by far the best out there! Thanks again for all your hard work. You help keep the spirit of Sebring alive and for that, I and the generations that follow, thank you!

  3. You’ve done it again my friend –
    Your story brought back many memories as I was there too. And once again, your photography is just outstanding. Your work as a corner marshal gave you the opportunity to get up very close and you made the most of it with your camera. Would that I had been anywhere near as good as you in those days. Congratulations also on a great story with several back-stories adding to it.
    Chuck Mclaughlin

  4. Louis. Great stuff as usual. I was there. I saw Pedro in the pit lane a bit later and asked what had happened between him and Donahue. With a smile he said ‘he reversed into me’!

  5. This material is simply astounding!. Thank you so much for the history and beautiful photos. Looking forward to the 65th running, I hope you stop by the Turn 2 Crew viewing trailer for some refreshments and food and have you take some pictures from its vantage point.

  6. You were just a few years after me at Uof F. I attended the race some 7 years in the 60s. A couple years I hitchhiked to the race from about across Sorority row. and got rides right to the track within 15-20 minutes! A couple years we ended up in the pit area at race’s end and helped pushing the winning car on the Alitalia ramp

  7. Our feet trod like paths but different years. My wife and I joined the SCCA- Central Florida Region-in the mid-80’s starting as corner workers. She ultimately chose to work grid and I ended up Chief of Tech. If ever there can be a surreal experience it’s being a race worker during the 12 hour of Sebring race back in the bacchanal, x-rated infield days.
    Your writing captures the flavor of the event and the photos are excellent. I may have to dive into pile of my old pictures and see what surfaces.
    Story: We were working the Green Park Chicane when the nose of the Miller Porsche came adrift. Looking to save it for the team to retrieve we put it in the bed of my pickup truck parked near our corner station. As it started toward sunset I could see the animals in the infield plot to jump the fence and swipe the nose. Not that I cared but I figured the damage that was gonna be done to my truck might be a wee tough to explain to my insurance man. We had control tell the Miller team to please come get their body parts or we were going to toss it to the crowd. They did.

  8. The Abarth 2000SP of Toly Arutunoff pictured at the hairpin was driven by Brian Goellnicht (not Bob). This was my first professional drive.

  9. Louis…
    Another superb article on the ’71 12 hours of Sebring race…thanks for including our team in your coverage… !

  10. Was a Grad Student at Colorado Univ. in 1970, and got involved with Del ‘Russo’ Taylor from Denver for this race in his Alfa GTA. Del T. was a ne’er-do-well huckster, but had won his class at Sebring a year or two prior. I towed Del’s GTA from Denver to Sebring with a volunteer crewman, Clark “The Happy Hippy” Hanson, we practiced and qualified, but then Peter ‘Perfect’ Gregg pitched a bitch to the organizers that our U2L class was too slow and a hazard…..and our entire class was NOT allowed to run the race. If I coulda’ got my hands on Peter Gregg I’d have gladly strangled him. After the race, I was in someone’s hospitality tent and Carroll Shelby stumbled in. They popped a bottle of champagne for CS, and we drank champagne straight out of the bottle with Carroll S., so the trip was memorable……not a total loss. It was one of those life experiences you cherish & never forget!

  11. Beautiful job putting this together Lou. This might even have been better than being there…..because there would have been no way to see it all in real time. Although I really would have loved to be there. Thank you for sharing!

  12. Page eight, Thanks for sharing Janet Guthrie’s email. Could you I.D. the other drivers on her team shown in that photo on page eight? Wonderful article and photos. Thanks, Andrew Chisholm

  13. Now that’s really good stuff…went to Bucknell University on the GI Bill back in the 50’s so can relate to your background, just wish I could follow your grasp of race photography.Thanks for a job well done.

  14. Thanks. Great photos. 1971 was the last Sebring I attended as a spectator. Crewed for your friend Phil Currin in 1973. Wish you had photographed from the other side of the Esses because we always camped on the side from which you photographed. Might have proof then that I was there;} The sound of the cars coming out of the esses and through the long bend towards the hairpin sticks with you forever.

  15. Lou – thank you so much for including Gene Bussian’s photo of Pedro Rodriguez and Jo Siffert. Both together in the same photo and both to be lost to the sport they loved by the end of the year. A very human tribute to these two drivers who gave so much to the sport they loved. I remember the BBC broadcast of Jo winning a Brands Hatch in 1968 and the Autosport report of Pedro’s win at Spa.

  16. The 1971 race at Sebring was my ninth year working timing and scoring at that race. I initially came to work at the track in 1963 as part of a group from the Cape Canaveral Sports Car Club. We all knew that the track was antiquated and we all had concerns about whether there would be another race after this year. All of us in the Central Florida Region of the SCCA had heard the rumors, but we all hoped there would be some agreement about safety improvements as well as technical improvements for people working the race and more improvements for spectators. But, that 1971 race certainly lived up to the kind of race that had one of the best fields we ever saw at Sebring. I had worked the Daytona race earlier that year (also doing T & S), so many of the cars were familiar to me. I think my boss (Dave Heinz) was racing in a Corvette with Or Costanzo that year. This car later became the fabled “Rebel Corvette #57” that won GT class a couple of years later at both Daytona and Sebring. But all of the cars I loved were there. I did not miss the Matra’s because they had to have been the loudest race cars ever built and by the time the last shift in the timing stand came around, you just wished those darn cars would go into the pits and never come back out. It was a great race, though, and I miss the original track with the “esses” that led onto the long gentle curve that led into the original hairpin, about 100 yds. from where the hairpin is now, and then the dash down the warehouse straight to Webster, a right-left combination that led cars out to the first of the back straights. Those were wonderful days to work timing and scoring, although the facilities were miserable. Sebring desperately needed updating as the 1965 downpour proved when the pits became a river and there was water all over the tables in the timing stand. But, in a masochistic sort of way, we all loved that place. The current track is much improved and much safer, but some of the “color” has been lost. As usual SCD has done a wonderful job of bringing all of that back for me. I went on, working timing and scoring until after 21 years there, I moved on to other masochistic forms of entertainment, long-distance ocean racing. But, I hope, Sebring will be around for a long time to come. It is a one-of-a-kind spectacle that we would miss greatly for its history and contribution to motorsports in America.

  17. Nice article, facts which have been unknown all these years. You know how to tell a story. I met Giunti when he was in Daytona for the 24 hour with the T-33 Alfa Romeo. He crunched it in practice, it was repaired but since the tubular frame was critical in carrying cooling from the engine to the radiator and had been bent and cracked, Alfa decided not to run the car. The quote at the time was, “We will not enter the fourth car. We will enter three cars and finish the three cars.” Which they did, finishing 1,2,3 in class. Guido Levetto

  18. Haven’t had a chance to read the article yet, but the photos are marvelous. Sobering to see so many departed greats.

  19. For anyone interested in prototype racing as I have most of my life,(worked at Sebring ’70, 71, and ’72) I invite readers to visit where you will find the only historical ‘insiders’ record of the full construction of the Alfa Romeo prototype “Type 33” cars from 1964 until the end around 1977. I have been privileged to live and work “Inside the Walls” of Autodelta in Settimo Milanese, (Milano) and was granted full authority to photograph everything inside (and outside !) of the secret complex. There exist no Ferrari, Lola, Porsche or Gulf factory images to be found on the Internet…secrecy has prevailed to this very day…..the only such image collection can be found in the series I photographed 40+ years ago along with 1972 Le Mans and that same years’ Targa Florio. Visit the site and be amazed. “I guarantee it or your money back! “

  20. OK, you did a hell of a lot of research; but, without your personal Sebring experience , photo-taking ability, and descriptive writing this fantastic account of the 1971 Sebring experience would not have been possible! Fantastic …… as usual.

  21. Good work as usual, Lou. I missed this race as well as the ’70 race thanks to Uncle Sam. Fort Benning in ’70 and Germany in ’71 (the latter not a complaint as there were worse places to be at that time!). I always enjoy the photos and tales of Pedro R. since he is still my favorite driver. Unfortunately, about 4 months later, I was about 100 yards or so away when he crashed in Herbi Müller’s Ferrari at the Norisring in Nürnberg in what was sort of a nothing Interserie race where Pedro went to have something to do that weekend. He was in the lead and pulling away when it happened. I didn’t see the crash itself but the black smoke was horrid looking. Then, only about 3 months after that, while returning from visiting a college friend who was on maneuvers at Grafenwöhr, I heard on Armed Forces Radio that Siffert had been killed, also in something of a nothing non-championship F1 race. As wonderful as that period in racing was, it did have a big down side. I look forward to your next article.

  22. “Step into the wayback machine Sherman” Another terrific account. Louis’ articles are far more detailed than anything at the time. Accurate and excelent photos. Thank You

  23. Lou, Another excellent article, your detailed writing and photographs really capture what the Golden Era of Sports Car Racing in Florida from the 60’s and ’70’s was like, almost as good as being there! I always look forward to reading all your stuff on SCD, you have done a wonderful job. Thank you!! – Lou S.

  24. Another Great Article Lou!! Did anyone notice the two corner workers had different opinions on who had the inside line for the same turn#9? I think the second report is more accurate for damage on the cars.

  25. Always enjoy reading, and then re-reading, your race profiles which are always accurate, full of interesting details, and packed with excellent photos.

  26. Here it is Christmas Eve and I am sitting in France reading this story again….must get a life! It was a great year at Sebring and I enjoy reliving it. Ed

  27. Sports Car Digest can publish all of your race articles every year and I will read each one every year ….. and enjoy reading your accounts and viewing the great photos each time !

  28. Louis,

    What a great article and fantastic photos, thank you. I was there and it was my first Sebring which so hooked me that I came to many more over the years. But the Porsche/Ferrari battles of that era were so exciting. I have some slides of this race that I will digitize and share. Even worked my way in to the pits during the race and got some shots of Mark Donohue. My first Sebring has a very special place in my heart.
