Narrative:
The flight was a routine training flight from vny. The clearance was the CANOG2 dp with the fim transition; altitude assignment 4;000 feet the departure was normal we were handed over to socal approach. Note this SID has an altitude restriction of 2.2 DME from the vny VOR at or below 1;700 feet. After meeting the climb restriction; the climb to 4;000 feet commenced. On a heading of 213 as required on the SID points directly toward a mountain range of around 3;500 feet with a 4;000 feet ATC altitude assignment. Because of the dp restriction requires an aircraft configuration change to climb to the 4;000 feet which resulted in a slower rate of climb to the assigned altitude. Conditions were VMC I could clearly see the mountain range. Additionally I used terrain avoidance tools such as twas and my mfd and a cross radial all for situational awareness. The 'fence' is a cross radial from a VOR (lax 316 radial) perpendicular to the flight path. This will help insure situational awareness on the departure and in the case of radio failure. As I reached my 'fence' I contacted socal approach questioning my upcoming turn as reminder to the controller and to confirm continued communication. The controller replied 'continue.' as I got closer to the mountains; I could see that I would clear the top possible by only 500 feet. I then requested a turn for terrain avoidance. The controller gave me the turn and vectored me on course. Almost immediately I received a low altitude alert 2x. My reply was I have visual contact with the terrain and expressed my dissatisfaction with the late vector. In my opinion this could be an item of safety had it been IMC or a possible an inexperienced instrument pilot. The takeaways from the flight are: the importance of pilot/controller communication and always maintain situation awareness. Use the terrain mode; taws/GPS and navigation cross radials. Additionally always brief high terrain before departure with the caption special conditions. Last but not least never be afraid to speak up whenever there is a question or doubt. If climb performance becomes an issue advise the controller.
