Turning my hips

So I finally have a pretty good swing down where when I miss a shot I know what I did wrong and know how to fix it. blah blah blah. One thing about my swing though is that it has little to no hip turn untill after I hit the ball and if i turn my hips too much before I hit the ball it causes a pretty big slice!! and since I am not using any hip turn during my swing I know i am losing distance on my drives (still hit about 260-270)

Why is it when i turn my hips I slice? could it be because when I am turning my hips that I make the club path to an out to in swing without realizing it?

260-270 stop complaining.  Pros get over 300 because the course are short and hard they get massive roll distances. So could i if I played that course condition.

There is nothing sacred about the hips turn. They do not have to reach any point in particular. Some instructors rejoice at such an extensive hip turn (one plane swing) other marvel at hitting against a firm left side. (2 plane swing)

There are 2 kinds of swings that have won big on the PGA tour,r big hip spin dragging the arms and little hip spin with the arms more on their own. Neither is better and they should not be intermixed. ie. dominating big hip spin while at the same time having dominating arms. The timing gets way way off when mixing techniques.

Think what you desire through:

For you to hit it straight your hips will be spinning a great deal around in a circle while at the same time your arms hands club must be be doing the same thing since they are attached to those spinning hips.

If your hands attached to spinning hips are going around in a circle then it stands to reason that if the ball is placed on that arc near your right arm when the ball is hit it will go into right field. IF THE FACE IS SQUARE TO TH ARC

If the ball is placed on the circular arc over to the Left arm area then  hit with square club face the ball will go to left field.

Anyway you should look at

Where the ball is placed on this arc in relation to the club head, face when spinning the hips a lot. Likely you will have to change the ball position a lot from where it is when not spinning the hips.  If not you will likely be hitting with an out to in path causing a slice. The set up used for less hip spin will not work.

You also have to alter your arm movements. The big hip spin will be pulling the Left shoulder away from the ball and you need to keep it out there.

Again There are 2 kinds of swings that have won big on the PGA tour big hip spin dragging the arms and little hip spin with the arms more on their own. Neither is better and they should not be intermixed.  ie. big hip spin  while at the same time having dominating arms.  The timing gets way way off when mixing techniques.

"Do you think he should his ball position? "    Only he knows by looking at his swing arc but I would guess 6 inches to the rear of present  to accommodate the swing change of extra hip rotation. But a huge factor is how is the club face altered by this hip change.  Personally I would not even be discussing this with myself because I would not introduce a hip change until I figured out how to fix the slice.  The point being hip change means bigger trouble and many adjustments.  That is the basic point of my comments. Hip change means other problems to go along with the slice.

As far as carry and roll. No blanket statement can be made.

I find the input on this issue interesting... I tend to find that when I'm slicing the ball it has more to do with me sliding my hips through the impact zone rather than opening them up and rotating through to face my target.  I currently definitely have a much more upper body focussed rotation and not much happening in my lower body on my typical swing and I'm working on initiating my downswing by opening up my right hip more rather than pushing it forward off my left (I'm a lefty).

When I first read the OP's question that's what immediately came to mind based on my issues...
