rpm's

[Pellethuntr2]

Anyone know roughly what the max rpm's are out of a stock 13hp Briggs?

IS the governor still on it?

 

[Pellethuntr2]

yes

3600

wow that seems pretty low...what does a 5hp get??

Most all sizes of industrial engines (including 5hp) like these come with Governor's that limit RPM's to 3600. Lots of us remove the Governor's to get more revs.

Same
about 3600

The difference between a 5hp and a 13hp is the amount of torque. You can figure out hp by using this simple formula: (MAX RPM x TORQUE) / 5252

Using this, you can figure out that a 5hp has about 7.25 ftlbs of torque and a 13hp has about 19 ftlbs.

RPM's and horsepower are unrelated.

I realize that...I just needed the numbers so I could calculate my top speed with the 13hp and then I was curious to how a 5hp compares...anyway thanks guys
