Narrative:
I was cleared for IFR departure at vny; after having had three larger aircraft (business jets) cleared for departure before me.the controller reminded me about wake turbulence avoidance. I made sure to lift-off in accordance with wake turbulence avoidance procedures. While on initial climb-out; I picked a vector that should have been offset from the business jets; but I clearly chose incorrectly.I hit significant wake turbulence and focused 100% of my attention on keeping the aircraft from rolling over.when the controller from socal came on the radio to tell me I missed the turn to 210 and was south of where I should be; I was shocked and corrected immediately.I know I should have declined the clearance and asked for more time for wake turbulence avoidance; but I thought there had been enough time. Clearly I was wrong; and lesson learned.I would also suggest that when controllers are clearing small planes for departure after larger jets; if there is to be a SID followed; that they wait some additional hold time.
