Notebook: What works for the race doesn't work for qualifying at Pocono

LONG
POND, Pa. -- At no other race track are qualifying and race setups more
radically different from each other than they are at Pocono Raceway.
Why?
Because the 2.5-mile triangular track has three vastly different
corners. For qualifying, crew chiefs have to reach a compromise that
works for all three turns, but in race trim, it's advantageous to nail
Turn 3 at the expense of the others.
"Getting
ready to qualify, you can't give up any (of the corners)," Martin Truex
Jr. told the NASCAR Wire Service. "You have to be fast through all the
turns. If you give up half a second in one of them, you're not going to
gain it back in the other two. You really have to do a good job
compromising. . . .
"In
the race, I still feel like getting off Turn 3 is probably the most
important. That's the corner that leads onto the longest straightaway,
where you can do the most passing -- or lose the most spots by getting
passed. So that's probably the most important for the race. But to be
fast for (qualifying), you have to be fast in all three."
In Saturday's qualifying lap, Truex lost momentum off Turn 1 and will start 23rd in the Pocono 400 presented by #NASCAR.
TIRE MISNOMERS
Drivers
routinely refer to tires as "hard" and "soft," -- hard tires supposedly
being the norm for a newly repaved race track such as Pocono.
In
reality, that's an oversimplification, because when Goodyear chooses a
tire for a resurfaced racetrack, the primary concern is heat tolerance,
not a "hardness" factor. Simply, on a smooth, repaved track, tires
retain heat because they don't wear, and because speeds don't fall off
significantly.
Rick Campbell, Goodyear's project director of tire development for NASCAR racing, explained the distinction.
"There's
very little wear, and one of our most efficient ways of dissipating
heat is through wear," Campbell told the NASCAR Wire Service. "Repaves
are not abrasive, so we don't get much wear. So we have to have to make
sure we have enough heat resistance built into the tire to be able to
tolerate a very low wear rate.
"Obviously, grip is a consideration, but heat resistance and the ability to run under those conditions is first and foremost."
Accordingly,
Goodyear made both construction and compound changes to the tires
selected for Pocono after an April test on the new surface. The
right-side tires Cup drivers are running this weekend are the same used
successfully on new pavement at Phoenix International Raceway in
February.
"The
other thing that repaves present that's different from most tracks is
that there's very little fall-off in grip over a fuel run," Campbell
said. "So lap times and the doom cycle a tire has to deal with are
constant. There's no relief over a fuel run. They're not slowing down."
What
that means for Sunday's race is that drivers are likely to pit just
inside their fuel windows for the final run -- or gamble and pit just
outside the window -- and remain on the track for the balance of the
race.
With so little fall-off in the tires, sacrificing track position for new rubber typically won't be a smart move.
IN FACT, IT'S A GAS
Higher
speeds at Pocono will increase fuel consumption in Sunday's race and
shorten the pit intervals for most teams. So don't be surprised to see
the first stop come much earlier than usual (probably well before the
30-lap mark), given that crew chiefs will be inclined to play it safe.
"The
track is fast, incredibly fast, approaching 12 miles per hour faster
than it was last year," says Howard Comstock of SRT Motorsports
Engineering, which supports the Penske Racing Dodge teams of Brad
Keselowski and AJ Allmendinger. "That's a big deal, and it makes a big
difference. . . .
"We
all know that this is a very important place for fuel economy. You
can't risk running out on the backstretch on a flat track, or you'll
never get back to the pits. So the speed is great, but how bad does that
hurt fuel economy? We're in the throttle so long around the track now
that it's using fuel to get the kind of speeds that we're seeing."
Accordingly, crew chiefs and race engineers will have to be particularly vigilant in keeping track of fuel mileage.
"I
think teams are going to have to be very careful about fuel economy,"
Comstock said. "They're going to have to be conservative for at least
the first stop, and I think they're going to have to watch it all day."
There will also be intense pressure on the fuelers to make sure the cell is filled.
