Also, your max rpm doesn't mean too much, apart from telling what your top speed is... you really want to be looking at how the rpm varies around the corners to get the boost set right... then set the turbo.
(and as syctherat and Benzhah have said, testing a motor unloaded is a sure fire way to making to stop suddenly as the rotor falls apart...)

Thanks all for your responses my question was aimed mainly to see if my telemetry was working correctly before putting on the track. I understand unloaded has no real use but at least I knew things were working right before going onto the track. For reference it was hitting 29,786RPM at the end of the straight I did try altering the gearing but this gave me the best temperature punch.
