Andy Wallace on the development of the Crawford
By: Bill King

Yesterday, Butch Leitzinger told us that Howard-Boss Motorsports teammate Andy Wallace, who is Crawford's test driver would be able to tell us more about the winter development. "Absolutely not," Wallace said with a wide-eyed smile. "Then everybody would know."

Assured that we weren't asking for engineering drawings, Wallace offered, "We've done suspension work, engine work, gearbox work and aero work. How's that?

"Really, it's just continuing improvement," he continued. "You're always trying something new, expecially since we've had to change tires now from Goodyears to Hoosiers. So that's a whole new deal now with springing, damping, that sort of thing, because obviously there's different spring rate of the tire now. Nobody really knows where they are now, because nobody's raced on the Hoosiers yet. So the first few hours of the race it's going to be quite new for everybody."

Asked about how the Hoosiers were working after the January test and the first day of practice for the 24, Wallace said, "We don't have very much forward bite or, let's say, in-line grip generally is not very high. So stopping's a problem; and going's a problem. But the cornering grip's not too bad. So it's a case of needing to bias the car toward getting better straightline traction."

Wallace said that the new arrangement with Penske Technology Group was dovetailing very well into the development of the Crawford. "In that group, you have the wind tunnel and the 7-post rig and all those things, and we've done quite a lot of work with this car. We have a wind tunnel model, which we take in there and get quite a lot of information. Having this arrangement means we can spend more time there than we have previously."

Asked if he was still living in England or had moved to the Mooresville area, Wallace quipped, "There's not enough rain in Mooresville. I've been quite happy the last few days with this wet weather. I mean, it keeps everything clean."
