The fourth day of testing during the NHRA National Time Trials at Firebird Raceway produced good results for some and continued frustration for others.

Fram-sponsored superstar Cory McClenathan was the quickest at the Monday Phoenix session with a 4.473, 331.45. Tony Schumacher remained atop the Top Fuel pecking order with an early-lifting 4.442 at only 326.08.

Brandon Bernstein upped his performance with a 4.479, 329.83 for the overall third place.

Rod Fuller continues to test the mono-strut car and his best is a 4.530, 326.40 from Sunday. His Monday best was a 4.611.

Ron Capps remained at the top of the Funny Car list on the strength of a solid 4.678, 325.92. He opened Monday’s testing with a 4.711, 329.75 which proved the best for Monday.

Gary Scelzi also had a strong Monday effort with a 4.785/326.56.

Dean Skuza continues to reacquaint himself with nitro Funny Cars with a 4.866/295.01. Skuza is driving Mike Ashley’s Torco Race Fuels-backed Dodge Charger.

Kenny Bernstein moved one step closer to fulfilling his licensing by running a 5.146/271.13 during the final session of the day.
