Narrative:

Cleared onto the runway to hold; asked by tower if we had preceding aircraft (just took off) in sight; (same type aircraft). We replied we did and were given a takeoff clearance. On climbout; we experienced the preceding aircraft's wake turbulence; full aileron deflection; we shallowed out our turn and climb rate but speed went well above 250 knots below 10K. Can't remember if pilot flying clicked off the autothrottles; I mentioned watch your speed but he was slow to correct. ATC 'never' said anything as we got switched to center from departure.we should have delayed our takeoff roll and/or asked ATC for a runway heading after takeoff to extend our ground track beyond the preceding aircraft's turn point.
