From 9k-7500 I had to fudge numbers my recording jumped from 9k down to 7500. Didn't want a gap in that area.

So the orange line must be horsepower and the purple line is how many kittens it could kill every second?

Interesting how it was making peak power while still "four-stroking"...

Other way.

Pulls go from the top down on these little guys.

Read from right to left

Have saw wide open at 14k 4 stroking. Apply load it starts picking up power. That little spike is the cleanup point. Keep loading it until the bottom rpm set. Which i had set around 6500.

What is interesting is where the max power is actually made..

Wonderful horsepower curve, peaking right in the working zone. Nicely done Joe.

Well, I may have created a one hit wonder with your saw...

I have a few ideas as to why. But i wouldn't be surprised to see it make even more power once fully broken in
