                  Well there was a video of that guy who done the 914 efi mods, he was running a 914 without a prop,,, to full noise too, because it was efi, the fuel just cut off, so it limited it too the max revs.but i would say if it was set up to idle with a 72" prop at say 1800, i would think it would easily get to 3k prob more with no prop, cause at 1800 the prop is pushing a lot of air.
