The speed restriction of I believe 200 is for below the class B and not in it, in class B it is still 250 KIAS for our restriction below 10,000. The reason for the slower speed below the class B is that this is where you are going to find the slower GA aircraft and it gives them time to find you in a see and avoid territory that they are operating in. As to the Loop departure our of SJC, if you exceed 200 KIAS, there is a good chance that your turn radius is going to increase to something larger than is being protected for the airspace that you are supposed to be climbing in. You have to remember that you are being separated from aircraft that are going into SFO, OAK and even HWD as well as numerous other airports. We don't build in restrictions if there is no need for them. As to coming out of class B and you keep your speed up, technically you are in violation as the controller can not waive that restriction to the FAR. If you don't have an inspector on your jumpseat, no one would probably ever know. If you are being assigned an airspeed and are not flying it (that is what I gathered from your post, if not I am sorry.) then in my opinion, you shouldn't be flying. Stated as a pilot and a controller in the colonies...
Here is the applicable FAR...
Sec. 91.117 - Aircraft speed.
(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).
(b) Unless otherwise authorized or required by ATC, no person may operate an aircraft at or below 2,500 feet above the surface within 4 nautical miles of the primary airport of a Class C or Class D airspace area at an indicated airspeed of more than 200 knots (230 mph.). This paragraph (b) does not apply to any operations within a Class B airspace area. Such operations shall comply with paragraph (a) of this section.
(c) No person may operate an aircraft in the airspace underlying a Class B airspace area designated for an airport or in a VFR corridor designated through such a Class B airspace area, at an indicated airspeed of more than 200 knots (230 mph).
(d) If the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed.
