Narrative:
On departure from sjc airport on an IFR clearance from runway 30R flying the LOUPE1 departure we turned right at the 1.8 DME; mark as directed by the FMS. The departure states to a heading of 120 and were cleared to 5000 ft. The FMS directed us to continue the turn to about a 155 degree heading. As it did this we relooked at the departure procedure and were discussing that we should turn back to a 120 degree heading and that the FMS was directing us to a point not depicted on the plate. At that time the controller called and asked our heading. We replied that we were heading 155 and turning back to 120 at that time. The controlled confirmed that 120 was indeed the required heading. Approximately 1 minute had elapsed from the time we turned to the 155 heading and corrected back to 120. Additionally the controller mentioned that we should look at far 91-117 when we landed. After level off at cruise; we looked up the regulation and concluded the departure takes you back under the sfo class B airspace and speed is restricted to 200 kts. I would recommend that the departure specifically state a speed restriction of 200 kts if that is indeed the desire. It's not apparent on any sjc plates that we are below sfo class B airspace and should maintain 200 kts and the controller never asked us to maintain a speed (we were at 250 kts).
