The problem with these types of threads is that the reader is forced to rely upon the vehicle owners word and unverifiable, often inaccurate speed measurment systems and devices. Radar guns need constant callibration to be accurate, GPS is inherently inaccurate for short distances, speed traps are too easily manipulated and videos too easily faked.
IMHO, the only speed claims that can be even marginally believed are the results of sanctioned, monitored events - and even those generate enough controversy to put their results into question.
So go ahead and post up your numbers but I for one (and I hope anyone with common sense) will remain skeptical.
