As we learned yesterday with Butch Hylton, crew chief on the No. 88 Snicker/Pedigree Ford Fusion, nothing is as hard as getting a clean lap around the hot, slick and very tight Chicagoland surface.
So we asked other veteran crew chiefs to give a look at the Chicago race and give a few more points of perspective.
Here's the word from Todd Berrier, crew chief for Kevin Harvick's No. 29 Shell Pennzoil Chevrolet, Paul Andrews, with the No. 43 Cheerios Dodge Charger and Bobby Labonte, and Billy Wilburn, crew chief on the No. 45 National Tire and Battery Dodge being driven by John Andretti.
Todd Berrier No. 29 Shell Pennzoil Chevrolet:
Chicago is really slick on sticker tires and the first six or seven laps are a balancing act like no other track. The trade off to get the car to not lose a second or more in that first few laps until the tires come in is it's so tight for the rest of the fuel run, it could be almost undrivable. So, you try to plan for how cautions you might see, how many stops you'll need to make it. Plan for what may play into your hand.
I'm sure there will be hard tire compound for this race and Chicago is known for long runs, total fuel runs and it could come down to gas mileage, having to make that very inconvenient stop with five to go.
With the current car we're running, the way we coil-bind these front ends, set-ups don't vary much from track to track. But being able to make adjustments is key. You got to stay ahead of the track conditions.
We've always had strong cars here. We'll race this race as hard as anybody
Paul Andrews No. 43 Cheerios Dodge Charger:
This time of year, at Chicagoland, the track is incredibly hot. With the heat and hard compound of these tires, the cars are going to be tight even as slippery as the track gets. We wind using some of our practice time to scuff tires as to take that newness off of them. That will make the tire better on the beginning of a run. That's the balance you have to have here, compromise has to be made. You'll see the whole fuel run. Strategy will come heavily into play.
Sometimes, that's the nature of intermediate tracks. You hope cautions fall your way, but you plan for the fuel runs.
The Busch race will see guys moving up into a second groove and you'll see some side by side racing on Sunday as well. But the bottom groove is still the shortest way around. This track is aging nicely, I think the surface gets better and better with every race. Both our drivers like Chicago.
Billy Wilburn No. 45 Tire Kingdom/NTB Dodge Charger:
A lap around Chicago from the crew chief's perspective: The car is going to have to have the right attitude, you run soft fronts and stiff rear springs. The car will get tighter as the race wears on and as you lose front grip. The pace will slow dramatically. You have to be easy getting into turn one, there's the bump over the tunnel and it can upset your car, and that's something the driver has to deal with, the rest of the track is really smooth. Coming out of turn two you carry a lot of momentum for the backstretch. The backstretch at Chicago not straight, it's still a sweeping turn that gets straightened out as much as possible. It's a fast part of the track and when you get to three and four, they are the easier corners to negotiate and you can get into them pretty hard. You want the car to be pretty free as those turns widen out quite a bit, even more so as the race wears on. Later in the race the groove through three and four is right out against the wall.
With John (Andretti), he's different in his approach to the corner than Kyle (Petty). John drives a deeper line, harder into the corner and tries to keep the car lower where Kyle charges the corner and drives a wider apex… so it's really a matter simple geometry and common sense to get the car working for John's style. You've got to have the adjustability to move as the groove moves up.
We tested at Kentucky a couple of weeks ago and we found some things in the aero package that we feel will work to our advantage with John. We moved the nose around a bit, spent some time in the wind tunnel and we're pleased with the results.
Tires are always big concern here as the front does lose grip very quickly. This track is hot and slick. We will scuff tires for qualifying and few sets for the race. You're still going to lose a second or two at the beginning of the run, but the scuffs will come in faster. This surface is going on eight years since it was repaved and it's seasoned well. It seems to favor the scuffs, where as with say Texas or another track, stickers may the way to go. Now as far as later in the race, guessing a four tire or two tire change, well Dale Jr. won a two tire change a couple of years ago, but it all depends on where you as far as track position. If I'm in the position of leading this race of running up front, I'm not going to shortchange myself, I'll want the best and newest stuff I've got on the car. If I'm running mid-pack, it'll be dictated to a large degree by what the guys behind me do as to what I'll do to get the best track position and looking to improve positions in the race. That will come as we approach the last couple of stops and see where we are on the track. Play the game in the way that's going to give you the best advantage.
