during mild to strong accel in the mid range od rpms. That's where it's used. But with dragging, you are always on the top end of the r's so it's never really a factor.
I'm sure your car will be sickly fast but RSR is right it might not make a good 1/4 miler. Unless you can build boost off the line and keep it up during shifts. Or you could just go with a 3 speed powerglide. Then you got a monster.
