Narrative:
On left engine start, as egt approached start limit, start was aborted. Egt was 578 degrees C for 1 second or less. Wind was 20 KTS with gusts up to 27 KTS directly up the tailpipe. Aircraft was repositioned with nose into the wind and a completely normal start was accomplished on both engines. Dispatch was notified of aborted start information via ACARS. No reply was received, so flight was continued. Almost immediately after takeoff text reply received that the flight was a no-go. Dispatch was contacted by radio on climb out and subsequently agreed that we should continue the flight. No further problems ensued and flight arrived at lax on schedule and with normal fuel reserves. Supplemental information from acn 633413: after 8 mins with no response and not finding any prohibitions in the manual, the captain elected to take off. Once airborne we received a 'no go' message via ACARS from dispatch saying we had exceeded a 545 egt limit.
