Narrative:

We got the PWK2 departure and were assigned a right turn to heading 030; 1 mile after departure. The first officer was the flying pilot from the left seat; I was pilot in command in the right seat. This was a part 91 leg without passengers. We briefed the departure; for a tight right turn. I had in the back of my head that we have to keep the speed low; to make this turn tight. The departure had no speed restrictions; nor did ATC assign a speed restriction. With the departure demanded to stay east of O'hare radial 345; I figured that 210 KTS would be a good speed for the turn. Our clean wing speed was 205 KTS. After take off the first officer called for autopilot and auto throttles to be engaged; he called for clean wing; and asked me to flight crew [flight level change] him to 250 KTS. This would be normal procedure and he knows that this aircraft is very unsafe at slow speeds; in turns; with a clean wing. I retracted the slats; since this is the procedure at clean wing speed; so that the slats don't get damaged. I advised against 250 KTS; pointing out; that this will increase the turn radius; at which point he twisted the speed bug up to 250 KTS himself. ATC was advising that our turn got too wide. At this point I partially took control and bugged 180 KTS. Without slats and in the turn we were close to a stall; so I increased the speed to 210 KTS. The first officer wanted to increase the bank angle to 45; which I did not allow due to the slow speed and clean wing; and being so close to stall. Apparently; at this point we had gone beyond the 345 radial for a brief time; and got the notification from ATC to call a phone number; when on the ground.I would suggest; to develop a new SID; one that includes a speed restriction. This will help pilots to determine configuration for the aircraft.
