Hey, I done 182km/h according to my RSM. It kept a record of it. The speedo meter is very accurate with the stock's speedometer dial, but the Rev is not accurate. The revs on the RSM is exactly 200 more than the stock tachometer.
I done this on the southern express way in adelaide, but the road was too short to do 200. I think I could have but the road ended before i reach that... I dont know if theres speed limiter, may be the apex RSM got rid of it?? RSM has the feature of getting rid of speed limiter? Im not sure.
here's some pics anyway...
