Narrative:

While talking to tampa and cleared into class B airspace I descended out of the class B airspace. I set up a normal cruise power setting and flew south off the coast. I then climbed back into class B and headed back east. I was new to a fast airplane and not used to the speeds it is capable of. In reviewing my flight I realized that I must have been at too high an airspeed below the class B airspace; about 230 knots. I will be sure to slow before descending below class B for now on.
