Another chainsaw dyno...

Wow lots of power and torque at low rpm. Nice job.

Nice job! What was the hp peak for stock? I couldn’t see it.

Nice job! What was the hp peak for stock? I couldn’t see it.

Stock: 5.61hp
Ported: 7.92hp

Peak was closer to 5.8

Like Joe said it was closer to 5.8hp. That 5.61 is just a rpm spot he picked on the graph.

I thought max hp should be the actual max hp on the graph. NO?

I feel dumb now, lol.

No worries man. I was confused too before another member pointed that out to me.

The numbers listed are the power at the thin vertical red line.

I can only pick one line, normally I pick the peak hp of the ported saw. Unless that peak is way higher than the stock saw.

On the 372 graph the line is at 10,100rpm. You can see that rpm listed in the far lower rt hand corner of the graph. Whatever rpm is in that spot is the rpm the numbers come from.

Ahh. Too bad the software cannot just pick out peak hp and torque of each saw and place it in the graph.

 

[MustangMike]

I was wondering why the graphs always seemed a little off from the stated #!

I just love this stuff! Really cool to Quantify vs “feels like”. Just add an awesome chain and smile a mile!

Just small tuning changes. Maybe 500 rpm each time. You can see how the impact it makes on the peak HP.

Oh, what fun we could have testing different fuels and oils
