large cc saws

[miker]

I know that the old stihl 090 was 137cc, but why no modern saws that big, stihl 088/880 husky 3120 and dolmar 166 were all 120 ish cc, modern tech, the newer saws would eat the old 090, in terms of speed ( maybe not torque tho ) i suppose weight comes into it ?

 

Just thinking like !

Same reason no one makes 500cc two man chainsaws anymore.
Don’t need it.
The 090 was a great saw 40 years ago.
But its very heavy, inefficient with fuel, very slow chain speed in the wood 6-8krpm,

compared with an 881...
It’s like your 3.5 litre rover vs a 3 litre golf turbo.
One might have a bigger displacement but modern tech will win everytime.
Have you ever used an 070/090?
It’s literally an engine with a couple of steel tubes welded on for handles.

Stihl asked me what I would like for a big milling saw.
250cc was my first answer???
But after using the 881 for nearly 6 months, to my surprise I discovered I’d been wrong.
You don’t need massive displacement.
It’s all about the resistance/drag from the teeth in the wood vs power vs functionality.
This is why I use different chain set ups for different length bars with the 880/881.
30” bar cross cut stihl full comp full chisel.
54” bar milling stihl full comp full chisel or granberg ripping chain.
84” bar milling Oregon hyperskip.
The hyperskip chain allows you to use ridiculous bars on single power heads without excessive strain on the engine.

I’ll be doing some comparison videos of the different chain setups shortly.
