I see you have some serious misconceptions about modern bowling. First, your hands and finger don't "torque that baby." The core of the ball has built in hook, and the more you try to hook it, the less it will hook. You don't throw the ball, you roll it, and unlike the old days, your timing should not be late, it should be leverage (neutral) timing. The idea is to get the thumb out first, and keep the fingers in the ball for as long as possible as you rotate through the ball rather than around it.
Since you are working with a coach (smart idea), I would suggest that you communicate your desire to increase your rev rate to him/her. Some of the advice that is offered up here and other bowling discussion sites can get you seriously screwed up.
Good Luck!
