Narrative:
Departed runway 1L sfo; left turn to intercept 350 degree radial on the offshore five departure. We started our left turn to 200 degrees at sepdy. Climbing at 5500 FPM through 6000 ft; just as we were handed off to norcal; the controller told us to stop our climb. I pushed the aircraft over to comply with the request. I stopped the climb at 8000 ft. We got a TA to monitor vertical speed; then an RA to descend. I was in the process of complying with the RA when norcal issued a right turn away from the CRJ200. I had the CRJ200 in sight during the TA and RA. The CRJ200 departed runway 1L at sfo ahead of our aircraft on the same SID. We had a much higher climb rate than the CRJ200 flight.

Title: LR60 DEP FROM RWY 1L AT SFO EXPERIENCED TCAS RA FROM PREVIOUS SAME RWY DEP; CTLR ISSUED SEPARATION TURNS.
Narrative: DEPARTED RWY 1L SFO; L TURN TO INTERCEPT 350 DEG RADIAL ON THE OFFSHORE FIVE DEP. WE STARTED OUR L TURN TO 200 DEGS AT SEPDY. CLBING AT 5500 FPM THROUGH 6000 FT; JUST AS WE WERE HANDED OFF TO NORCAL; THE CTLR TOLD US TO STOP OUR CLB. I PUSHED THE ACFT OVER TO COMPLY WITH THE REQUEST. I STOPPED THE CLB AT 8000 FT. WE GOT A TA TO MONITOR VERT SPD; THEN AN RA TO DSND. I WAS IN THE PROCESS OF COMPLYING WITH THE RA WHEN NORCAL ISSUED A R TURN AWAY FROM THE CRJ200. I HAD THE CRJ200 IN SIGHT DURING THE TA AND RA. THE CRJ200 DEPARTED RWY 1L AT SFO AHEAD OF OUR ACFT ON THE SAME SID. WE HAD A MUCH HIGHER CLB RATE THAN THE CRJ200 FLT.
