Interesting how much those curves are alike.

Would be cool to see a few more Hybrids Dyno tested from a couple more builders then all put on same chart.

I am going to guess yours has more compression...

Mine has somewhere around 190-200. I haven’t tested it in a long time

And new 70cc leader.

Dang that's a strong runner!!!

The hybrid Mike did for me is right there.the torque curve explains why I’m enjoying running .404 on mine. I’m not saying that my @CFB is as stout as this particular one but it’s no slouch.

Mike is super meticulous and pays attention to detail. He builds very strong saws. Anything from the Silver Eagle is a saw worth owning...[emoji106][emoji482]

A different 60cc battling for the lead...

Looks like MOFO gots the 60cc Stihls down...[emoji106][emoji631][emoji482]

Another stout 60cc



Another flat power curve on this one.

I knew I was right in the ballpark with the 361 hp when I guessed 7 ish. It was comparable to a stock 572 and stock 441 in timed cuts with same bar. Since the stock 572 made 7 on the dyno I figured 361 was in the ballpark.

I'm really interested to see how the dyno results equate to real life usage. If I recall correctly, the 262XP actually cut faster than the 361 in same wood, same chain. But yet the 361 clobbered the 262XP on the dyno.
SO... this is all very interesting.

Wood -same
Fuel - slightly different
Technique-Same saw guy

We try to test by taking all variables out of the equation as much as possible. Mostly use same chain and bar if possible.

Same wood is never the same wood

Straight stick of oak. We do the best we can. Come on. Work with me here. Lol

Not sure i could call a 4.2% different peak to peak "clobbered"
