B737 first officer reports on captain's pitot static instrument failures during takeoff. The takeoff...

Narrative:

A normal takeoff roll was begun with the captain flying. An eighty-knot callout was made by the first officer. The captain noticed that the airspeed indicator was not functioning. The takeoff roll was continued to avoid a high speed abort. The normal callouts were made by the pilot not flying and the captain (pilot flying) rotated the aircraft for takeoff. The captain saw that barometric altimeter and vsi were not working as well. Rather than fly cross cockpit; the captain turned the controls over to the first officer. Aside from the captain's pitot static instrument not working; a momentary hydraulic (hydraulic) light flashed and the well recall was pushed. The flight cont annunciation on the recall remained illuminated. No other caution or warning lights were illuminated on the overhead and hydraulic pressure check was normal. The level off occurred a 2;500 ft MSL and a normal traffic pattern was flown to an uneventful landing. An emergency was declared and emergency equipment was dispatched to standby for the landing. The aircraft returned to the gate and maintenance was called to troubleshoot and repair the problem.a functional check flight on the aircraft should have been accomplished prior to the aircraft being put back into service. The aircraft had the winglet modification installed.
