Indy 500: Hondas running turned down in practice, says Power

Power and team-mate Helio Castroneves topped the times on the second day of practice at Indy, as the only cars to post an average lap speed above 224mph.

"As a team, we did a lot of homework in the off-season for this race, and we tested here twice, so we're getting the most out of our package," said Power.

"I know Chevy is working really hard, and obviously you can see that our speeds are pretty good right now.

"The Hondas are turned down quite a bit, we can see that.

"But I feel like our alone [no-tow] speed is actually good compared to what they were running.

"We're working together with Chevy and everybody else so that we can keep up the good pace and move forward."

Power added that he expects a more accurate picture to emerge later in the week when teams start preparing for the weekend qualifying sessions.

"It's all to do with whether people want to practice qualifying," he said.

"That's when you start to see some bigger speeds, and we don't get the [extra qualifying] boost until Friday and probably won't practice qualifying until Thursday."

Castroneves said it was important for the Chevrolet teams not to focus on Honda's performance this week.

"We've just got to focus on our work," said the three-time Indy 500 winner. "We can only speculate.

"We can't keep talking about [Honda], we can only focus on our way, and Chevy - as Will touched on the subject - is working really hard.

"Maybe with 1.4-bar boost [as used in qualifying at IMS], it might be different; at this point, even we don't know.

"But we don't see as much of the difference [between engine manufacturers] as last year, where they were strong.

"If they are, we've just got to make sure we have a better car."
