Saw video thread

[Wolverine]

Isn't this pushing past the limit of the chain?!?

Never heard the DozerDan 17k+ stories?☺

 

[PA Dan]

There a real piece of wood!

All time best saw video ever!

Never heard the DozerDan 17k+ stories?☺

I would love to hear these stories! Please?

 

[Wolverine]

I suck @ tellin' a story. This saw can and has done 17+. Guess ya had to be there...

Doesn't sound like it's tuned real fast.
14k ?

 

[jmssaws]

Is the higher revs a characteristic of these hybrid saws?

That's what I hear.
I honestly don't know much about them
I've only built 3 and the other 2 were years ago and best I can remember ran like *s-word. Lol
I did some of what I heard and winged the rest. Got lucky on it
I got a couple more here to do so I'll see what there about it recon.

@Deets066 and @Canadian farm boy
Are the hybrid guys,I just followed what they already did.

Later in the day it was wicked up... no video.


Not my vid (Dan's):

Yes, but usually at the expense of torque. That has been the "mystery", to find the torque. Usually, a ported 046/460 will just out power them.

OK Jason, how much timing advance, and you gonna reveal the transfer changes, cause I think that is where the secrets are buried! Oh, and did I mention, I want a strong running hybrid ... BAD!!!

You are still using the non D cylinder?

It's a stihl branded 460 cylinder with a round chamber. I've never been able to tell any difference in them ported.
It's advanced a lot. 040
I changed the roof angle from the tunnel all the way out and put 1 more degree opening angle.
I did a couple hours work but only raised one side one degree.
The number isn't as important as what happens when the port opens.
I think rpm is all in the transfers and not exhaust height or intake duration.
Exhaust is almost 103 and 4 strokes past 16k.

 

[Deets066]

I think intake duration plays a lot on a hybrid too. There is a sweet spot, they really seem to free up around 80

 

[MustangMike]

Thanks guys, for your excellent comments. The beauty of a site like this is that the collective knowledge allows us to attain heights that likely no one would be able to achieve on their own.

Jason, I think the high RPMs are also driven by the reduced case volume, which acts like a crank stuffer, but it can also make torque difficult to find.

anyone that says hybrids don't make torque have never run deetsey-d's hybrid. fact.

I was very impressed with his hybrid (and the 2 others) at the CT GTG. Now I'm trying to determine why they were so different than previous ones I have seen. FYI, all 3 had D chamber cylinders!

The one I ran had tons of torque, so much that I commented I would add one to my all orange fleet in a heartbeat.

Very impressive to be running a 9 pin w/32" bar on a saw of that size. Any secrets you wish to reveal about what makes it so strong? Also, do you find the D cylinders work better on these? Thanks.

Yes, I would like one also, but I want one with the torque! Right now, they are the exception (but yes, they are out there).

Not all D cylinders are great, the compression bump isn't needed. Easy enough to get 200 psi with a regular chamber.

The port timing is what makes a good runner. If a cylinder has good timing in the trans stock, then it will be a runner.

For me anyway, everyone has their own way

WOW! Deetsey that som-*b-word cuts
