None of the various hacks I have seen so-far do anything but work around an arbitary number. Changing the speed a motor will assist to does not make a motor susceptible to blowing - that is bad design and poor quality components. A design engineer working on one particular brand advised me that they can run double the peak output of their motor for several hours with no issues.
Exactly.
Agree, I wasn't clear that I don't think de-restricting your motor means you will blow your motor, just that if you have an issues, it may make warrantying it difficult. The main "issue" I have seen from derestricting is with the battery, as the system is drawing power for longer and more of the time, and the lifespan/range of the battery gets depleted quicker accordingly.
