I am trying to learn a lot more about motors than I now know. I have good knowledge of propellers but my knowledge of motors is non existent. When I was a kid I rebuilt one, only because I didn't have the money to buy a new one, but what little knowledge I had then I have lost with time and age.
I have never really understood the relationships between HP and Torque with different loads from different props and now it seems I need to know this information to further my research on propellers. I have a halfway acceptable power curve for a 350 CI motor with 292 maximum HP at 4,800 RPM, but I need the actual HP and or Torque numbers from a 1,000 RPM up to the maximum rated RPM at 250 RPM sequences for a motor so I can verify the REALITY of what is happening with specific props on a specific motor at any RPM. If I can get these numbers then I can prove to myself exactly what is going on at any specific RPM with that motor.
I have spent a lot of time and effort in building some spread sheets to identify everything I want to know that is going on. I just need the curves to verify or NOT verify what I think is happening. Below is a picture of the 350 motor information that I am trying to use to know what is happening at any point in time. This not the complete spreadsheet as it is too wide to place here and still be able to read the numbers, so I had to cut it.
So if any of you have a complete RPM and Torque curve I would appreciate it very much.
