Narrative:
The departure procedure at sna is so complicated that neither pilot can monitor th east other because of the duties required on takeoff. When climb 2 power was selected at 800', the thrust management system did not command climb power. It was tried again before manually retarding the throttles. The aircraft was climbing at 4500 FPM. At this point, with a pitch attitude of 26 degrees, a turn was required 1 mi from the runway. With the throttle problem and excessive climb rate, plus the turn, we exceeded 3000' by 400'. While all this was happening, the new TCA was calling traffic. The vol cannot be turned down when the TCAS goes off. This was a traffic advisory alert, not a resolution advisory alert, yet it still diverts one's attention from the departure procedure.

Title: ALT DEVIATION OVERSHOT.
Narrative: THE DEP PROC AT SNA IS SO COMPLICATED THAT NEITHER PLT CAN MONITOR TH E OTHER BECAUSE OF THE DUTIES REQUIRED ON TKOF. WHEN CLIMB 2 PWR WAS SELECTED AT 800', THE THRUST MGMNT SYS DID NOT COMMAND CLB PWR. IT WAS TRIED AGAIN BEFORE MANUALLY RETARDING THE THROTTLES. THE ACFT WAS CLBING AT 4500 FPM. AT THIS POINT, WITH A PITCH ATTITUDE OF 26 DEGS, A TURN WAS REQUIRED 1 MI FROM THE RWY. WITH THE THROTTLE PROB AND EXCESSIVE CLB RATE, PLUS THE TURN, WE EXCEEDED 3000' BY 400'. WHILE ALL THIS WAS HAPPENING, THE NEW TCA WAS CALLING TFC. THE VOL CANNOT BE TURNED DOWN WHEN THE TCAS GOES OFF. THIS WAS A TFC ADVISORY ALERT, NOT A RESOLUTION ADVISORY ALERT, YET IT STILL DIVERTS ONE'S ATTN FROM THE DEP PROC.
