I was talking to Marty Roberts a year or so ago about what types of speed can the KR2 (that was what Marty flew) could handle. I was looking back then about a 120 hp engine that could get me up to the 200 mph range. He said he had his plane over 230 mph more than once and no problems. He also said his plane (and other KR2's) could handle 4-5 G's.
