It'll be close. My FD with 565 rwhp was trapping about the same as the ZR-1's at the Mojave mile. IMO they had slightly better aero than my setup but I had-400 lbs less weight. I've driven both cars and when TC is active it feels like the racelogic cycles quicker than the GM system. It felt less intrusive under hard accel.
Now if he throws s snout, pulley, E85 and a tune at his you won't stand a chance......
