An air carrier mdt turboprop was momentarily yawed abruptly when passing a taxiway intersection during takeoff roll causing apprehension to the first officer making the takeoff. He believes that all aircraft should be restr in making high power settings when tailed to a runway.

Narrative:
Flight was from phl to bum. We were told to taxi to runway 27R intersection taxiway east for takeoff. We started our takeoff roll down runway 27R. We were heavy and had a fairly long takeoff roll. As we passed taxiway north we were hit with a strong jet blast from an aircraft on that taxiway. We yawed abruptly but continued to V1, vr and rotated without incident. Had we been a little lighter, we would have become airborne at that point. It may have become very interesting. I think, when takeoffs are issued from this intersection, care should be taken to insure that all jets on txwys north and M are at idle.

Narrative: FLT WAS FROM PHL TO BUM. WE WERE TOLD TO TAXI TO RWY 27R INTXN TXWY E FOR TKOF. WE STARTED OUR TKOF ROLL DOWN RWY 27R. WE WERE HVY AND HAD A FAIRLY LONG TKOF ROLL. AS WE PASSED TXWY N WE WERE HIT WITH A STRONG JET BLAST FROM AN ACFT ON THAT TXWY. WE YAWED ABRUPTLY BUT CONTINUED TO V1, VR AND ROTATED WITHOUT INCIDENT. HAD WE BEEN A LITTLE LIGHTER, WE WOULD HAVE BECOME AIRBORNE AT THAT POINT. IT MAY HAVE BECOME VERY INTERESTING. I THINK, WHEN TKOFS ARE ISSUED FROM THIS INTXN, CARE SHOULD BE TAKEN TO INSURE THAT ALL JETS ON TXWYS N AND M ARE AT IDLE.
