To get more distance , try hitting the ball straighter instead of harder.  Concentrate on hitting the ball in the sweet spot of the clubface or with a square clubface at impact. If you have ever hit the sweet spot, you know that these shots fly farther than the shots you hit off-center in the heel or the toe.

For every quarter inch you hit the ball outside the sweet spot, you lose up to 10 yards of distance. So for maximum power, improve your swing technique to consistently hit the ball in the center of the clubface. 

To be consistent, you should strive to deliver the clubface to the ball square at impact every time. To keep your clubface square throughout your swing, you need to understand how your grip affects the clubface.

If your grip is too strong, then you will return the clubface closed at impact.

If your grip is too weak, then you will return the clubface open at impact.

Strive to achieve a neutral grip so that you can return the clubface to impact square for a straight, solid shot.
