Another chainsaw dyno...

[Red97]

Lmao!!!

 

[Bigmac]

Holy hell Batman! That there was funny!

 

[Red97]

Laptop mounted to the dyno. Nice little flex arm. Should keep the vibration down.

8am dyno runs?

 

[Red97]

6" arm repeats a lot better from run to run

Echo was extra rich today. Can see it in the graph on the far side of peak power.



The red run was the cleanest run, but you can see peak power and tq hardly change.

All 3 runs have a .1hp spread...

I like the torque curve on the echo. Gets stronger the more it’s pulled down.

This graph doesn’t appear to be “backwards” reading. So I see a torque decrease with rpm. No?

Yes, the torque curve increased when rpm dropped instead of staying flat or decreasing.

Gotcha, so the runs are still starting on the right and going left.

Yes
What I circled is the torque curve. Unless I am seeing it wrong. It gets stronger as rpm drops.

 

[cuinrearview]

The runs start at WOT, or the right of the graph. Load is applied and that drops the RPM.

 

[MustangMike]

Let me fix that for ya, what I don't like is how torque drops as RPMs increase!

Just funning with ya!

Wasn’t 100% sure this new setup was the same.



Carry on, nothing to see here.
