In my fittest year, when I came close to an outdoor sub-5hr imperial century (4,400' of climbing, actual moving time of 5:15 and an Avg Power of 212W over 5 hrs), I had an outdoor riding FTP60 of 233 watts (3.2W/kg), an indoor trainer FTP60 of 259 watts, and a peak 2-3 second sprint output of 1,050 watts. And my power curve shows that while riding outdoors, I once held 300 watts for a maximum of 6.5mins., and riding indoors I once held 300 watts for 37mins.
A 300 watt outdoor FTP60 was WAY out of my reach.
