Do 315 Tires slow your car down?

Yes, like they guy above me said it is a traction -vs- rotating mass/friction issue. If you are going for top speed with a soft launch the more skinny tire would be better... ala...the tires on the landspeed cars they race in the lake beds.

You also have to take into consideration the weight of your 11" wheel. The rotational mass of some is lighter or heavier than others. So you may or may not lose very much power, but like hitmanws6 said, the wider tire will provide more traction to plant more power to the ground.
