Fuel injection tests at Kentucky Speedway

UPDATE NASCAR Sprint Cup engine builders got a good look at how the new fuel-injection systems work with their engines when teams got to spend Thursday at Kentucky Speedway with cars outfitted with the new units. During the nearly of six hours of open Cup testing at the track, teams only could test one car – but can have a second car outfitted with fuel injection. NASCAR plans to begin using fuel injection with the 2012 Daytona 500. McLaren Electronic Systems and Freescale Semiconductor produce the engine control units, and teams buy the system directly from McLaren. Five engine builders had cars on the track testing the new system – Hendrick Motorsports (with Aric Almirola driving), Roush Yates Engines/Roush Fenway Racing (Ricky Stenhouse NOT Greg Biffle/Matt Kenseth), Earnhardt Childress Racing/Richard Childress Racing (Austin Dillon), Toyota Racing Development/Michael Waltrip Racing (Mike Skinner) and Penske Racing (Sam Hornish Jr.) participated. Many teams have tested the systems at other tracks, but this will be the first open test at a track where the teams actually race. NASCAR plans to have more tests throughout the year, and it will have the Cup teams at Daytona next January for further testing. SceneDaily

07/03/11 The Sprint Cup Series will not be the only thing making its debut next weekend at Kentucky Speedway. The track will also host the first test of cars designed with electronic fuel injection. During an open test day Thursday, originally scheduled so Cup teams would have extra time on a track they have not previously competed, teams will also be allowed to test cars with fuel injection. NASCAR officials expect each of the four manufacturers to have at least one car with EFI on the track. They will all likely be driven by drivers not competing in Saturday's Cup race.
