Safety at the Track

Call it a horrible coincidence. Call it a problem. Call it what you will. Just don't ignore it.

With the deaths of two drivers at nearly the same spot on the same racetrack within two months in remarkably similar circumstances, there is more going on than meets the eye.

"I think it's a combination of things," said Larry McReynolds, the crew chief on Mike Skinner's No. 31 Winston Cup Chevrolet. "But there's no doubt we've got a problem. We can't all just sit back and wait for the next one to happen."

McReynolds, in addition to being one of the best crew chiefs, is one of the more astute observers of stock car racing.

"Is it a problem with Loudon, N.H., any more than it is a problem with Indianapolis or Pocono or Richmond?" McReynolds said. "Anywhere where you've got a flat entrance with no banking to scrub the speed off, you've got the potential for a problem.

"Maybe I'm just missing something totally, but there's no question in my mind that it was just coincidental that both these situations happened at Loudon, N.H."

The death of 19-year-old Adam Petty on May 12, followed by the fatal crash of Winston Cup driver Kenny Irwin two weeks ago at New Hampshire International Speedway, has the whole racing world scratching its head and digging for answers.

The early consensus was, and to some extent still is, that the throttles stuck on both Petty's No. 45 Busch Series car and Irwin's No. 42 Winston Cup car as they entered the third turn.

While a problem at some tracks, a stuck throttle is not always life-threatening because the steeper banking enables the car to lose some speed before it impacts the wall.

At tracks with relatively little banking in the turns -- at New Hampshire it's 12 degrees, at Miami-Homestead 9.25 -- they don't have that luxury. Even with the driver jamming on the brakes, it only takes fractions of a second before a car hits the wall.

No one is positive, however, that a hung throttle was the cause.

"Specifically, we are still undergoing an investigation," said Mike Helton, NASCAR's chief operating officer. "We have not found anything conclusive at this point, but we looked at the car with a lot of help from different people within the garage area. Certainly there may be something that comes out of the investigation.

"NASCAR is always working on safety elements and issues, and after Adam's accident in May we heightened the look at accelerators, carburetors and the linkage in between and we're very heavily active right now trying to see what NASCAR may be able to react to."

There have always been hung throttles, and for myriad reasons. Often, the steel rod that connects the carburetor becomes pinched between the air cleaner and the engine during a race. A piece of tape may come off the air cleaner and cause the linkage to stick or a "booster", a device in each barrel of the carburetor, may break and cause the throttle to hang.

But there are remedies for that. The simplest is a toe strap, a device that fits over the end of the accelerator pedal much like the toe of a shoe, that allows a driver to manually unstick the throttle by pulling his foot off the accelerator.

That's fine, noted defending Winston Cup champion Dale Jarrett, if you have time to use it.

"I've had throttles hang," Jarrett said. "It's the worst feeling that a driver will ever have. I've told my son Jason, he's had it happen twice already and I told him, 'You've experienced the worst thing.' That and fire, but that's just the most helpless feeling, especially on a shorter type race track where you have no banking. You can't react quick enough. Your first reactions are to stomp on the brakes and that doesn't do anything when you're going wide open. It's a terrible feeling."

One step further, McReynolds said, is a kill switch located near the driver's hands on the steering wheel, but even that relies on a driver's reaction time. The third option is to take it out of his hands with an automatic kill switch.

"We've looked at what the modifieds run," McReynolds said. "It's not driver-activated. It's in a little tube and it connects to the throttle rod. It has a microswitch in it and if the throttle doesn't return and there's no pressure applied to the accelerator, that microswitch will come apart and it will kill the power to the motor.

"You think about all these things that a driver can do, but he's got only a millisecond to do it. Most of these places, you're pretty deep into the corner before you back off the throttle anyhow. An automatic kill switch might help."

The other area being closely examined is the walls themselves. All Winston Cup tracks have solid concrete walls, some with dirt banking behind them. At Indianapolis and both road courses on which the Winston Cup cars run, they also have Styrofoam barriers in front of the concrete.

The one or two feet of foam between the wall and the car, McReynolds said, could make the difference between a driver being sore and a driver not surviving a hard impact.

"I go back to two or three weeks ago and Jimmie Johnson's wreck in the Busch Series race at Watkins Glen," McReynolds said. "God knows how fast that boy was running when he hit that wall head-on. But there was a significant thickness of foam there and a guard rail behind it that has a little bit of give.

"I'm totally against guard rails by themselves because they're dangerous. But if you take a guard rail that has a little give to it and put a two-foot thick foam barrier in front of it, you might have something to solve a lot of this."

It is not a panacea, but it might be a step in the right direction.

"It is another thing we're looking at," said Kevin Triplett, NASCAR's director of operations. "For every action, there is a reaction. If somebody hits one of those barriers and kicks the rest of that barrier out in front of everybody else, what does that create?

"At a road course race three weeks ago, a team had to go to a backup car because of the damage done to their car when two cars in front of them hit a barrier and kicked it out in front of them. That's why when we react, we try to react with something that has more positives than negatives."

The key word, McReynolds said, is "react."

"The one thing you don't want to do is to say, 'Next year when we build new tracks we can do this,' " McReynolds said. "We need to fix it now. Loudon needs to be fixed before we go back there in September. We need for it to happen at Pocono before we go there.

"There's no question in my mind that they (NASCAR) are taking it seriously, trying to figure out where to go and what to do with it."
