NASCAR announced more changes for Sprint Cup Series teams after the second day of testing at Daytona International Speedway on Friday.

Teams will receive a smaller restrictor plate with an opening of 29/32nd of an inch, down from 15/16ths, to decrease the amount of air intake to the engine. The radiator opening was shrunk from 3.5-by-18 inches to 2-by-20 inches, or from 63 square inches to 40. And the pressure relief valve is now 21 pounds per square inch from the 25psi they used Friday.

The top speed in Friday's test session was set 90 minutes into the afternoon by Kurt Busch. He ran a 206.058-mph average lap working in tandem with his regular drafting partner, Regan Smith. Busch hit 210.9 mph down the backstretch, the fastest portion of the track.

Testing for the 2012 Daytona 500 will conclude Saturday.
