Narrative:

Departed lakeland airport event as part of a continuous line of departures. The VFR departure procedure instructs to fly 'straight out' (in this case due west) until 3 miles from airport before turning on course (reference NOTAM). I departed runway 27 and flew due west at 800 feet and 95 mph. Shortly before turning on course to 240 degrees; at about 2.5 miles from the airport; a fast low-wing airplane crossed above me; from left to right; at about a 45 degree angle to the northwest. I didn't see the airplane until it was directly overhead and moving very quickly to the northwest. I recall that the aircraft cleared for takeoff behind me was a bonanza; which was very likely the fast airplane I observed crossing my path. Fortunately; I was flying below the typical 1000 MSL; so we didn't touch; but otherwise... My high wing and the bonanza low wing set up the perfect 'can't see and avoid' situation. This was compounded by the close sequenced takeoff timing at lal; the bonanza pilot turning on course before the 3 mile limit; and the lack of radar (transponder) advisories. In addition; bonanza pilot was apparently unaware that he was following a much slower aircraft (200 mph vs 100 mph cruise). On departure; he should have noted that slower traffic was ahead and moderated his speed accordingly. The NOTAM is very clear about matching aircraft speeds for the approach pattern and approach holding pattern; but is silent on the departures. If the bonanza had reduced power until the 3 mile point; then our separation would have been improved.

Title: After departing using the departure procedure described in the NOTAM; the pilot noticed a faster aircraft pass overhead. This other aircraft apparently turned earlier than the designated turn point.
