Another chainsaw dyno...

[huskihl]

The 500 felt to me like it maintained better with a longer bar A little more forgiving

Maybe as the saw is lugged down and heats up in the real world, the fuel injection/autotune feeds it more... constantly tuning for max performance. Whether as the 461 your stuck with one tune until you tweak the settings. When you lean out too much in long cuts you usually loose torque.

I think they have to be pretty lean to actually lose torque. Like not 4 stroking at all and then some. That little dip in the 500i graph probably isn’t there under a more constant and consistent load and is what we’d actually feel running a longer bar

Appears like the 461 has it beat in hp/torque slightly from 8000-9000ish. Probably equals a slightly torquier feeling saw in the wood when lugged. Makes sense with the stroke on both saws. Although I’m sure you have to have the 461 tuned optimally to reproduce those results... whether as the 500i is always tuned. It will be more consistent.

This is why I asked about doing a slower or more “even” application of load. Was the saw not self adjusting fast enough? One would think the 500i should outperform the 461 even marginally especially with the short bar for the load testing. I have run the 500i and tuned 461s and I believe the 500i was better with the longer bars, more even power/torque when dogged in and leaned on. Personal opinion, obviously.

I’m curious if they actually have a timing curve to help boost revs, that’s almost what it looks like. It’s beyond standard cutting RPM and well pass peak power, so I don’t think he would feel it in anything larger than 12” wood. What rpm would they cut in the wood? 10k? 10.5k? That’s something that always interest me after seeing a dyno run, Is what rpm was it happy cutting at compared to the peak RPM on the dyno?

You don’t have to lie to me, I’m still your friend. Sort of.

So how did they fare vs deets hybrid? I cant see how much peak hp they made.

There may be a new leader in the 70cc class...
Maybe new leader in 60cc too!

There is

Awesome numbers for these Hybrids though .
These are the Shiznit!

 

[Red97]

Top hybrid


And new 70cc leader.

Another 044 hybrid real close to the 10hp mark.

 

[Sawrain]

Amazing, a combo combined with porting skill that really works.

And the value of an 044 around here just went up.

 

[dustinwilt68]

Congrats to all! Especially CFB for an amazing build!

 

[Deets066]

Where should we start the bidding on the@Canadian farm boy hybrid?

$1,000?
$1,200?



Nice lookin graph on that one

 

[RI Chevy]

Gotta be as good as if not better than insanoized or psychoized. Lol. [emoji1787][emoji3061][emoji2957][emoji106][emoji631]
They don't come cheap...

I'll sell mine fo 15 hunnid

I love the FLAT torque curves...[emoji106]
Nice job for both guys.
