Narrative:
Tower notified us to taxi into 'position and hold' on runway 27 san; and be ready for an immediate takeoff. The captain announced that he was going to 'spool up.' upon taking the runway; the captain did not stop the aircraft. I announced twice 'we are position and hold only!' captain said 'he'll clear us in a second.' meanwhile the engines are showing 60% N1 and the captain is dragging the brakes; with speed increasing. We had rolled almost to the delta intersection before takeoff clearance was given. Full takeoff power was not indicated until we had passed intersection D. Therefore; our takeoff data was invalid. Brakes would have been very hot for an abort. We also never had 'held' (in position) so it could be easily argued that we had begun our takeoff roll. Tower asked for our altitude before handing us off to departure. I wonder if we also violated a required climb gradient?

Title: A B737-700 FO RPTS THE CAPT DID NOT HOLD POS AND THEN SET FULL TKOF PWR AT SAN RWY 27 TXWY D THUS VOIDING PERFORMANCE REQUIREMENTS.
Narrative: TWR NOTIFIED US TO TAXI INTO 'POS AND HOLD' ON RWY 27 SAN; AND BE READY FOR AN IMMEDIATE TKOF. THE CAPT ANNOUNCED THAT HE WAS GOING TO 'SPOOL UP.' UPON TAKING THE RWY; THE CAPT DID NOT STOP THE ACFT. I ANNOUNCED TWICE 'WE ARE POS AND HOLD ONLY!' CAPT SAID 'HE'LL CLR US IN A SECOND.' MEANWHILE THE ENGS ARE SHOWING 60% N1 AND THE CAPT IS DRAGGING THE BRAKES; WITH SPD INCREASING. WE HAD ROLLED ALMOST TO THE DELTA INTXN BEFORE TKOF CLRNC WAS GIVEN. FULL TKOF PWR WAS NOT INDICATED UNTIL WE HAD PASSED INTXN D. THEREFORE; OUR TKOF DATA WAS INVALID. BRAKES WOULD HAVE BEEN VERY HOT FOR AN ABORT. WE ALSO NEVER HAD 'HELD' (IN POS) SO IT COULD BE EASILY ARGUED THAT WE HAD BEGUN OUR TKOF ROLL. TWR ASKED FOR OUR ALT BEFORE HANDING US OFF TO DEP. I WONDER IF WE ALSO VIOLATED A REQUIRED CLB GRADIENT?
