"This car is working well - ours definitely seems to be very tunable, it feels very much like last year's car," said a slightly surprised-sounding Wilson. Obviously, everyone is nervous; it's a new car. You're not sure what to expect. We had last year's car for eight years, and I think they started out at the 218 range and got up to 228 when we were finished. It just takes time to work out the details and fine-tune it. I think the speeds are going to be just fine in qualifying."
With six cars already topping 220mph this early in the week of practice at Indianapolis, it seemed that the series organisers' announcement of an extra 1.5 PSI of turbo boost for Fast Friday, Pole Day and Bump Day might not have been necessary after all.
"I don't think it's going to change it beyond what we can't adjust for," said Fisher when asked how she felt the planned turbo boost would affect her drivers later this week. "I think they have a good comprehension of what changes it's going to make and be able to anticipate that, sort of like what we anticipated yesterday with a new car and a new situation with the aero package.
"As long as you're prepared, that's the biggest part of showing up," she added.
IZOD IndyCar Series vice president of technology Will Phillips explained that the extra turbo boost was to make sure the fans were satisfied with what they saw next weekend.
"Indy isn't just about the race, qualifying is also a big show as well," he said. "It adds work to the teams, they have to prepare for two different things [but] I think it's a good story from a PR perspective because it's something that wasn't different before."
But Phillips ruled out allowing the boost to remain for the race itself.
"I think there's concern at this stage, the original engine regs were meant to be at 130 KpA. I don't know whether they would last probably the most strenuous duty cycle that they'll see at more than that yet. We just don't know," he told SPEED.com
The teams had a full six hours of practice available to them on Sunday, after some threatened showed failed to materialise. 31 drivers took part and turned a total of 1138 laps on the day with Wade Cunningham putting in the most track time as he successfully completed the third and final phase of his Rookie Orientation program.
There were five cautions for a total of 51 minutes during the session, for routine debris clearance and track inspection.
