Wow! Those are some shit hot numbers no matter what gear it's in.
I am impressed also that it was a Dyno Dynamics machine, whenever I see big numbers it always seems to be a Dynojet machine (they are always waaaay optimistic).
As for the gear thingy. Sure it does make a bit of a difference which gear you're in but 3rd to 4th isn't a big difference anyway, and it definatly gives us a good ballpark idea. As you all know HP = Torque x revs so sure a lower gear gives you more torque but at the expense of revs. That is why we use HP as a yardstick and not torque (you can get as much torque as you want, just ask Archimedes....lever long enough, place to stand etc.) So in theory it shouldn't make any difference, but it does. I think it's more because of the efficiency of the gears than the torque multiplication effect, as someone pointed out even if you use a 1:1 fourth you still have a 4:1 diff then who knows what wheel radius. Gear efficiency vary a bit depending on the angle the teeth are meshing at, loads on bearings etc. I think these may be more of a factor than the ratio itself (though these may be some of the side effects of the ratio).
Another interesting point in the HP/Torque thing is that it is possible to have huge torque and ZERO HP. DC Electric motors do this when they're stalled, they actually produce maximum torque at 0 RPM (they are switched on but loaded up until they can't rotate anymore, they will burn out if this is sustained).
