That a 3120?

those look like 041’s to me bro, least a 3120 can pull its own weight lol

 

[Red97]

Well I think the dolly broke it again....

Going to call in the am and see if they have any warranty on the arm I just replaced.

[Bilge Rat]

Do we need to start a collection for a spare arm?
We can't have this thing going down cause we is addicted to the graphs.

Dang husky and Dolly's always breaking the dyno, guess we know what makes the power

Just some speculation here...

I believe you said the unit is rated for 30hp and a bunch of rpm... but...
Is there a spec for max torque?

I'd guess it doesn't care as much about hp as it does about torque.
When the input is geared 2-1, the torque applied to the arm is doubled.
I think the typical application for the land & sea unit is running directly off the crank.

Not sure how abruptly you can slow a saw down with the valve setup but I know on the disc brake dyno it was possible to get really large spikes in torque if the brake was a bit overly applied, like 4-5 times the saws rated output.

Then again maybe it's just seeing some bad vibe/harmonics, that sort of thing is really difficult to ferret out.

Technically the first to break it was a mofo 44/46 hybrid. I think my penchant for breaking things wore off on my saw...
