Felt like crunching some numbers

Hey all,
I was sitting at work today and felt like crunching some numbers. My 1025r amazes me at how fast the rated rpms are (3200). I decided that they were so high as to be able to use a good amount of gear reduction in order to get the most out of the engine. This makes sense since it would be able to keep the engine small and still get some good torque numbers. I decided to compare the 1 series to the 2 series since the 2 series don't have much more hp but have a much lower rated rpm speed (2500). Here are my findings, maybe they will interest some of you. If not, oh well, here is some idle reading. :munch:

1025r 40.7 ft/lbs @ 3,200 rpm
241.18 ft/lbs @ 540 rear pto
62.0187 ft/lbs @ 2100 mid pto

2025r 40.27 ft/lbs @ 2,500 rpm
186.42 ft/lbs @540 rear pto
47.92 ft/lbs @ 2100 mid pto

2035r 63 ft/lbs @ 2,500 rpm
291.67 ft/lbs @ 540 rear pto
74.97 ft/lbs @ 2100 mid pto
*results shown do not take into account losses resulting from the flywheel to the pto. Overall loss should be close to the same percentage across the board. These numbers are to only be used as a reference and should not be taken to heart.


From what I see it looks as if the little 1025 nearly keeps up with the bigger 2035 while overpowering the 2025. :thumbup1gif:
