NASCAR is still on target to move to fuel injection engines in 2011.

NASCAR vice president of competition Robin Pemberton says teams have been given parameters to use when testing fuel injection.

Pemberton says he's expecting NASCAR to receive more data in the next month.

Fuel injection is being explored in an effort to make stock cars more fuel efficient. The current cars have used carburetors since the 1980s, and the carburetor has little application to what is currently sold on showroom floors.
