NASCAR getting ready to test fuel injectors

The first on-track test of fuel injection in NASCAR's Sprint Cup Series could come as early as July 7 at Kentucky Speedway, provided NASCAR finalizes specifications for system hardware and software in time for teams to prepare. Because the Cup series will race at Kentucky for the first time on July 9, NASCAR has OK'd extra practice on Thursday, July 7. Cup teams are scheduled to spend four hours on the track that day, and Earnhardt-Childress Racing Engines chief engine builder Danny Lawrence hopes that will also provide the first test of fuel injection for the series.

"Hopefully they'll know (about specifications) in a week or two, because there's getting to be a pretty big push for people to run at the Kentucky test," Lawrence told Sporting News on Sunday at Martinsville Speedway. "They're going to have a test day before the race, and if they have everything spec'ed out by then, we'll try to run there – that'll be our first deal. I know they're working on it really hard, and hopefully, they'll have it figured out in a few days."

NASCAR announced in February at Daytona International Speedway that McLaren and Freescale Semiconductor will partner in the development and manufacture of engine control units (ECUs) designed to manage fuel and ignition systems in Cup cars. Fuel injection will replace the carburetors that have been part of Cup engines since the series' inception in 1949, with the transition targeted for the 2012 season. Sporting News
