Narrative:

I was departing pdx runway 28R. Tower informed me of traffic crossing pdx airspace to land at vuo when clearing me for takeoff. Upon reaching about 500 ft; I had visual contact of the traffic and pdx indicated that I could turn to 310 degrees at pilot's discretion. I continued climbing in the turn. Upon reaching 310 degrees; tower asked me whether I would be able to overclb the other traffic. I had lost visual contact of the other traffic; and thought that it was below my cowl. I informed tower that I was at my maximum climb rate and that I could not see the other traffic. Tower requested me to maintain visual separation and contact pdx departure. When traffic appears to be in the pattern for vuo; aircraft departing pdx runway 28 right should not be turned northbound until reaching 15000 ft.
