Dyson Racing at the 54th Annual Mobil 1 12 Hours of Sebring

For Dyson Racing, “it was the best of times, it was the worst of times.” And although sports car racing tragedy doesn’t rise to the level of the French Revolution, Dyson Racing’s adventures at Sebring through the years have not been far short of dramatic. Although they have never won here, they have been as close as you can get. Who can forget James Weaver chasing JJ Lehto into the night in 1999, only to fall nine seconds short? 2006 was a year of high hopes – and low expectations. There was a car that might yet be a great car, a car that James Weaver described as “…a very nice piece…” with which the team has “…just scratched the surface. If we were testing here next January or February, we would be lapping in the 1:46s.”

Still, it was a very new car; the least tested on the grid. Between them, the two Lola B06 / 10 AERs had tested three times, about 1,100 miles. On two tracks of different lengths, that’s about 350 laps – 175 per car. That would be about halfway through the 54th Mobil 1 12 Hours of Sebring if nothing went wrong. Chris Dyson echoed Weaver’s assessment after a very satisfying test at Road Atlanta, “It is the early days for a brand-new car, but we have to be cautiously optimistic for the 12 Hours of Sebring. We like our chances for the year. The car is so much better (than its predecessor at Dyson, the Lola B01 / 60 AER) in so many different areas, and this is only the beginning.” The high hopes were that anything could happen; of the nine cars likely to be at the head of the grid, four would start their maiden race; for two it would be only the second start in competition, and two, though well tested, were the team’s former Lola B01 / 60s, cars whose strength is not the endurance required for Sebring’s punishing twelve hours. Realistically, however, team manager Randall Kelsey spoke for all when he said, “We’ll be happy to get to the seventy percent (of race distance) and collect the (American Le Mans Series championship) points.”

Preparation at Sebring
Monday and Tuesday were “Promoter Test” days at Sebring, extra track time to test and sort. The #20 car, to be driven by Chris Dyson and Guy Smith, had a new engine to replace the one used in the very successful test at Road Atlanta. The #16 car got that engine as a replacement on Tuesday; the one previous was the very first AER the team received right off the “bench” in January, and had been a bit problematical. The team was fighting some leaks – major enough to cut Tuesday’s testing short, but minor enough to continue to run while awaiting parts from England. The two cars put forty-one more laps in the books Wednesday morning. “I think some of the problems we were having are unique to the #16 engine that we replaced yesterday,” said team manager Randall Kelsey. “We’re going to run today and replace parts tonight.”

Wednesday afternoon was nearly an unqualified success. The two Lolas ran well throughout the session. The minor leaks were gone. The reason? “J-B Weld – the leaks are gone. So much for “high tech.” In even the very top level of racing, there are still those things about which the shade tree mechanic can say “I’ve done that!” But it wasn’t all good. Guy Smith was piloting the #20 Lola and “we saw his tire starting to go down (on the telemetry from the car),” said Team Manager Randall Kelsey. “We radioed him, but he couldn’t understand us and kept his pace into turn 1, where the car ”went to full lock – he (Guy) did a great job saving it, he didn’t hit anything, but the tire came off the wheel, and the car had to be retrieved. There was some damage to the floor – we have a spare – otherwise it’s fine.” The team was getting a delivery of spares in the afternoon. A new engine for #16 had already arrived, to replace the temporary installation of the engine out of the #20 Lola.

At the end of Wednesday, Chris Dyson summed up the team’s progress. “We’ve had a good week so far.” As for the new Lola, “The package is good, that much we knew after testing the first car here and after a great test at Atlanta for the second car,” said Dyson. “Compared to the B01 / 60 this car is a big step forward in downforce, the engine is more drivable, the whole car is less pitch sensitive…, and while the ride height is still vital, it isn’t as absolutely critical as (it was) for the B01 / 60.”

“I set a 1:50.5 on my first flying lap here this week, which proves what a really good car it is,” said Andy Wallace, whose time in the car has been limited. “My second lap was spoilt by traffic, then Guy had his puncture in the #20 car and the session was stopped – but James and Butch have done about 50 laps in the car today.”

The #16 Lola B06 / 10 received its new AER twin turbo engine on Wednesday night, but no sooner did it hit the track for Thursday morning’s session than things went wrong – turbo pressure, air flow. Symptoms that were the result of a split intake plenum, later traced to a team error in installation. It was back to the garage, with no running time – and no ignition mapping – on the new V8. I wouldn’t be the first time the team’s gone out for qualifying with an unmapped engine, and the answer we got from Randall Kelsey was a philosophical, “What’s the worst we can do, seventh?”

Meanwhile, they were chasing handling problems in the #20 Lola. After the session, they’d have to check everything, but were confident that they’d find the cause, probably damage as a result of Guy Smith’s puncture on Wednesday afternoon. About that they were half right. It wasn’t found before the qualifying session, but during, and yes, it was the result of residual damage from the Wednesday Turn 1 blowout.

Qualifying
The outcome of all that was that the two Dyson Lola B06 / 10s finished up in fifth and sixth, the team pleased that those positions could be accomplished with one broken car – #20 suffered suspension failure early in the session. Guy Smith had just set his qualifying time on his first timed “out” lap, and he reckoned a lower time still was on the cards - before he arrived at Turn One and felt the car suddenly go loose in the rear. The team later concluded that the failure was most a result of the #20 car’s puncture problem the day before.

With the loss of the morning session, and #16 with its unmapped engine, the two cars made up the third row of the grid, after the two Audis and the two Porsches.

Rob Dyson was philosophical – and consistent – observing, as he has before with his cars occupying the front row, that “They don’t pay the money on today’s result.”

The team participated with both cars in the night practice session with the primary goal of assessing tires for cooler temperatures. The #20 car’s driving strength was happy to see their car back in running order. “We weren’t concentrating on lap times,” Chris Dyson said afterwards. “These are our race engines and we’re trying to keep the mileage on the cars as low as possible.”

Friday’s single session, after qualifying, is one many teams skip, done with their preparation and not interested in risking the hardware. Dyson Racing wasn’t in a position to engage in that luxury. James Weaver was working with the set-up on a #16 car that was suffering from understeer, his best lap coming late in the session after going a bit “tighter.” Chris Dyson tested some new compound rubber, and was about to turn over to Guy Smith when a large volume of white smoke caused him to shut down while exiting pit lane. He immediately reported that the engine seemed to be fine; the shut down was precautionary. Later, it seemed it was the continuation of the relatively benign (but sometimes spectacular) turbo oil loss. Rob Dyson was explaining that and the position / performance of a scavenging pump in the paddock later, and told us, “I think we’ll be OK.” Race day was upon us. “Finally!” some would say. “Already?” would be another thought at Dyson Racing.

Morning warm-up was uneventful for most, but the two Dyson Lolas would move up a starting position on the grid, to fourth and fifth. The pole-winning #2 Audi R10 TDI had a heat exchanger failure, and the repair would cause it to be required to start from pit lane when it could not be repaired in time to make the grid.

The Race: The Beginning One-third – Little Problems Add Up, but in Second Place
This was a week of nearly perfect weather, and race day was no exception. It was 77° F. when the green flag flew at 10:45 AM for the start of the 54th 12 Hours of Sebring. Guy Smith challenged the two Porsches early, then just thirteen minutes in was back in the pits with a punctured right rear tire – that one again. Guy was in position four when he came in; he went out in fourteenth. So much for qualifying position in a twelve hour race. There were only eleven hours and forty-seven minutes to go now.

Unfortunately, it would be only twenty minutes before the Guy Smith / Chris Dyson Lola B06 / 40 AER returned to the team’s pit just beyond the entrance to pit lane (often called “pit in”). A second puncture relegated the #20 car to 19th position. Ah, well, there were still eleven hours and twenty-seven minutes to catch up, wasn’t there? Soon after, fifty-one minutes after the start, James Weaver brought the #16 Lola into the pits for a routine, fuel only, stop. Those Michelins would see another stint.

So, two punctures and a fuel stop, both cars were now on their way, and it should have been time for the Dyson team to take a deep breath. Nope. Almost simultaneously with James’ return to the track, Guy Smith slowed and stopped at turn 12. What now? It felt to Guy like it ran out of fuel, but the car had been refueled on the previous stops for punctures. It took two tries to restart (in these systems, that’s “recycle the ignition” as certain other checks and activities take place in the electronics; but it’s the same now with our street cars, isn’t it?), and Guy was into the pits again, this third time to figure out what had gone wrong. It was something that had not happened in 1,100 miles of testing. No time for standing around head-scratching of course, so they first had Guy engage the reserve fuel pump; that wasn’t it. All things considered, it really didn’t take long to determine the cause of the problem. There is a sensor for engine oil pressure of course, and a switch that will shut the engine down when that pressure falls below a pre-set value. That value’s initial setting was too high for these racing conditions, so it was reset to a still-safe lower value and the Lola B06 / 10 AER was once again on its way. At an hour into the race the #20 Lola was five laps down, while the #16 car was one of only four cars on the lead lap.

That wouldn’t last. Just a few minutes later, James came to a stop at turn ten. It was the same problem as the sister car, and the #16 car restarted, returned to the pit, did the reset, was refueled, had tires changed, and Weaver was on his way once again. It was noon. The on-course stop, and additional time in the pit had now put the #16 Lola three laps down from the leading #1 Audi at an hour and a half into the race. The #20 Dyson entry was further back still after its three incidents. The reasonable expectation to learn more about the car and complete seventy percent of the race laps for points was still in play. The more hopeful scenarios were remote at best.

Guy Smith finally put in a “normal” full stint of fifty-one minutes before refueling; no tires this time. The Michelins were able to go two stints; that’s good news. Two hours into the race, James Weaver was nearing the end of his second stint, and had picked up some ground; he was now shown on lap sixty-two just one lap behind the leading Audis. That’s about two minutes, not much in this race. Spirits were good. Chris Dyson said, with a smile, that the race pace of the two Lolas was, “Just fine. Good in the gasoline powered division.” James handed over to Butch Leitzinger after two hours and seven minutes.

Unfortunately, it would now be the #16 car’s turn to suffer different new car maladies. Sebring is relentless on all who race here. Fifteen minutes into his first stint he was back in the pits. A sensor had failed in the turbo oil circuit; that was handled simply by “turning off” the resulting “failure mode,” and Butch was on his way again, only to slow on the back straight. “I don’t think it’s (the engine) going to last much longer, it feels like ****,” said the exasperated Leitzinger. Butch was wrong…

But after selecting a back-up fuel map, he was again on his way. Meanwhile, Guy Smith had put in another trouble-free stint of fifty-eight minutes, and turned the car over to Chris Dyson two hours and forty-five minutes into the twelve hour race. The car was running pretty well now. Both were. For all of seventeen minutes. This is a busy business sometimes. Butch’s braking wasn’t feeling right, and instruments showed brake bias strongly toward the front in the “safety pin” hairpin – that’s the nearly 180 degree turn in front of the Chateau Elan hotel – indicating weakened rear brakes. The reading was even more toward the front after braking into the pit, so the team immediately went for the rear brakes. Bingo! A leak! Fix that, bleed the brakes, download a new fuel map, and out thirteen minutes later. Just before Butch’s stop, the clock marked the end of the third hour; #16 was three laps down, in third, while #20 was five laps down, in fourth place among the LMP1s. Leitzinger returned to the track thirteen laps down. Following a stop just past three hours Chris Dyson put in a run of sixty-four minutes between stops, between taking fuel and four tires at 2:34 PM. Unhappily, he was back on pit lane just six minutes later to serve time for an alleged pit lane speeding violation and for someone’s goggles up while over the wall on the previous stop. In the meantime, however, the #1 Audi went behind the wall with an overheating problem. Soon after the fourth hour, then, Chris would take over second place, ten laps back of the remaining Audi. Butch Leitzinger brought the #16 Lola in for fuel only just past four hours. Eight hours still to race, Chris Dyson’s ten laps something about eighteen minutes. One “bobble” up front and…..?

The Race: The Middle One-third – Steady Running for one, Trouble for the other
It wasn’t long before that reverie was interrupted, though. Just as Dyson began setting a series of quick laps as fuel began to burn off, the #20 car again had a problem shutting down over the bumps into Turn 17. That brought Chris in a bit early, thirty-nine minutes after his last stop, for a check, tires, fuel, and a driver change to Guy Smith. The one hour, forty-five minute stint would be all for the American in the 2006 12 Hours.

Meanwhile, Leitzinger had completed two hours, thirty-two minutes in #16, and handed over to Andy Wallace for the latter’s first drive, in a routine tires and fuel stop. Things had been quite smooth, finally, for the car, through two stops and one hundred minutes. Something had to happen, and did. Just before five hours, and only a few minutes after starting his stint, Andy was back with a flat left rear tire. Sensors allow the team to see tires lose pressure, so again, Andy was able to pit for the change and avoided any on-course catastrophe. Meanwhile, Guy Smith had suffered another on-course engine shut-off, starting a sequence of problems that would finally sideline the #20 Lola for good. The combination put the two cars in second and third place, just seconds apart on the same lap, 141, eight behind the leader at the end of five hours.

Just twelve minutes later, Guy Smith came in, trailing smoke all the way down pit lane on his way behind the wall. With a further oil pressure loss, he shut down the AER V8. With 144 laps complete, the Lola would get an oil pump transplant in a one-hour, six-minute stop. At five and a half hours, Andy and the #16 Lola were in second place in LMP1, but had slipped to ten laps down, still within range if the Audi ahead had trouble. It was widely believed up and down the pits, that the Audi was running hot. Overheating had retired the sister car. #16 was running strong. In the midst of the first really major failure – the oil pump on the Dyson / Smith Lola – hope for a surprise was still alive.

Andy turned the #16 car over to James Weaver after a stint totaling 1:45, six hours and forty minutes into the race, and James drove an uneventful hour and a half before turning over to Butch just past eight hours.

At the eight hour mark, the car was in second, and had closed to within six laps of the Capello / Kristensen / McNish Audi R10 diesel. It hadn’t been that good for Guy Smith. His #20 had no sooner got back on track after the oil pump replacement than he reported the car “reeks of fuel.” Not good. So back behind the wall, for another repair, this time a fuel system gasket. That took an hour. Still, the team was intent on getting both cars to seventy-percent of the winner’s laps. They calculated they could still lose forty-five minutes and achieve that. Back to it, then, at 6:10 PM, seven and a half hours into the 54th 12 Hours of Sebring. Owing to attrition elsewhere in the class, the car was still fourth, but was sixty-seven laps back at the eight hour. Just when the effort looked to regain traction, a plastic bag lodged in one of the side radiators spiked the temperatures. Guy and the crew nursed the overheating car and fought the fight for the next thirty-five minutes, but would retire the Lola thirty-five minutes later at 7:20 PM, after more than eight and a half hours. No points scored for either Smith or Dyson, who were bitterly disappointed, after having one of the quickest cars on the track in the race, and who had hoped to start the 2006 championship campaign with a strong result. It was not to be.

The Race: The Last One Third – The New Lola’s first Podium Finish
By that time, Butch was well into his first hour-long stint. At hour nine, just before his first fuel and tire stop he was in second, six laps behind the leader. The Lola was keeping pace now with the diesel class, too. The second stint in this set was forty-six minutes; the next stop wasn’t entirely routine, the V8 would need a liter of oil – it took a bit to find the fitting – and there was some concern about engine temperature and oil pressure. Andy Wallace took over from Butch at 8:40 PM. At ten hours in, the #16 Lola had completed 284 laps to the leader’s 291. Still “lurking.” Two hours to go. Prospects Good. Much achieved.

Andy took to the track for a relatively uneventful fifty-four minutes, before pitting for fuel at 9:34 PM, ten hours and fifty minutes into the twelve hour race. Just bring it home, now, for second place. Not so easy, though. In nine minutes, Andy is back, reporting a “horrible sound,” and the car bottoming on the front straight. The crew jumps on the back of the car; are the shocks broken? A spring? They can’t tell. Andy goes back out, but reports it’s worse. (The jumping didn’t help.) So he returns, on leader’s lap 324 at 9:50 PM, just into the final hour. The crew replaces both rear shocks, and raises the ride height two turns. Andy heads back out. The leader has completed lap 328. Andy’s down thirteen laps now. Get it home. A full course caution comes out at 10:00 PM, the course is back to green twenty minutes later. Andy drives it to the finish just twenty-five minutes later, in second place in LMP1 (fifth overall). A podium the first time out, and an overall finish ahead of both Penke Porsches and one of the diesel R10s. And while the #20 car didn’t earn points for its third place in LMP1, the Dyson team enjoys the satisfaction of its drivers sandwiching the winning Audi pilots on the class podium.

The Gang is Satisfied - and Optimistic
Butch Leitzinger: "With a brand new car it was likely we'd have some difficulties, what was surprising was that we had so few. We are very happy to be standing here. As you drive around this track there is so much energy from the fans, you can tell its Sebring!"

“It is amazing how well the team came together for this race. The car was so new and had quite a few problems and not much practice, but they got everything right for the race. We went into this with our eyes open, knowing the challenge we faced with a brand new car. But for the car to run as strong as it has gives everybody a positive boost for the season

James Weaver: (how was the track this year) "It was consistently grippy. " (about the car) "When I drove it, it worked fine, it was Butch and Andy that broke it". (Is this car easier to handle than last year’s) "We've been working very hard this year to stay in shape, its definitely less work (to drive) than last year's car. I'm the oldest, so I guess I'm in the best shape."

“It was a typical Sebring week – fighting and struggling with a number of minor problems, but in the end, we got some good points. The car behaved itself amazingly well during the race, no major dramas and acquitted itself quite well.”

Andy Wallace: “The car is actually very nice to drive; it really is a good car. Of course we knew coming into this race that it was very new and we have had our fair share of teething problems. But it was dead strong during the race. It has very good feel which is very important in a race car and I very much enjoy driving it.”

Chris Dyson: “It is disappointing that the #20 car did not score points this event: the car was the best it’s been all weekend. But the whole program has to start somewhere and I am very pleased with my teammate, Guy Smith and how we worked together all week. I am sorry for the guys - they put in such an effort, but it is a building block for this year as we have learned an incredible amount these past six weeks. Congratulations to James, Butch and Andy for their great run.”

Guy Smith: “Little bit disappointed this weekend that we couldn’t score any points. That was our aim for the week, but that is racing and in particular endurance racing. But all in all it has been positive. We know the car is good and it ran well through the race. It is fast. With the engine we have some good data and we know what we need to continue to improve on our performance.”

Randall Kelsey: “I am so proud of our guys. No matter what problems the new cars threw at them, they rose to the challenge. We were lucky if we averaged four hours of sleep a night. It was a long week, but they still maintained their sense of humor. There is not stronger work ethic than what you find in racing and I will put our guys up against any team.”

Rob Dyson (left): “It would have been great if we had not had the overheating problems on the #20 car and the few minor problems on the #16. Dealing with a new package, you expect some more catastrophic things to happen, but the thing ran like a Swiss watch, and it was absolutely astounding how well we did.”

With the experience of a twelve hour race in its first outing, barely fifty days after it turned a wheel for the first time, Lola B06 / 10 and the Dyson team appear ready to take on what comes next. Testing, of course, and then that very different evening street race in Houston in May. They’re eager to get there.
