While executing the Teterboro Eight SID our aircraft lost separation with traffic operating to/from EWR. The loss of separation was reported to the crew after the fact by an FAA inspector. At the time of the incident there was no indication given by TCAS or ATC that there was a traffic conflict of any kind. Winds at 1;500 FT were in excess of 60 KTS and may have contributed to the loss of separation.
During takeoff on Runway 24 at TEB; and during the initial climb on the TEB 8 SID; Runway 24; we encountered strong winds at both the surface level and during climb; along with light to moderate chop. The surface winds were approximately 290 degrees at 20-25 KTS and low level windshear was being advised. During our initial turn on the TEB 8; we noticed while leveling at 1;500 FT the winds were 300 degrees at approximately 35-40 KTS. We initiated our turn to a 280 degree heading as per the SID at the appropriate time. Due to strong wind conditions I am concerned we encroached on the EWR final corridor. At no time was there instance of a TA; RA; or an ATC advisory or alert. We continued on the departure procedure and were given a climb and a northwesterly turn almost immediately upon check in with N90 TRACON. The initial clearance from TEB Clearance Delivery was the RUUDY SID; however we requested; and received; the TEB 8 SID.
HS125 crew is informed after the fact by an FAA inspector of a loss of separation incident departing TEB on the TEB 8 SID.  Low level windshear and strong surface winds added to the crews workload during takeoff phase.
