here are some detailed tests I did between the 461 and 660.
461 - ended up with a 3x ported muffler. I actually tested this out against other setups and it was the fastest. I also took out the limiter tabs and was able to extract some more power going richer. I have it as good as I think I can get it with out other mods like porting etc.
660 - during the tests I switched muff mod combos. But I still haven't settled on one particular muffler mod yet. Limit tabs were not removed as I still had room. So I guess I feel like the saw might have more to go yet on the muff mods.
Both saws are R version with HO oiler.

20" bar - both saws share a slightly used (2 test cuts) Stihl RS chain & also a slightly used (2 test cuts) Stihl RSLH (sq. grd half skip) chain. 461 did cuts first then
1st 461 with RS chain
cut 1 oak log#1 - 10.7
cut 2 oak log#2-10.5
cut 3 cherry - 18.6
then 660 with same RS chain
cut 1 oak log #1 - 8.7 sec
cut 2 oak log#2 - 10.4 sec
cut 3 cherry - 16.7 sec
I did the cuts this way so the first cut would make sure the saw was warmed up (although I already warmed up the saw prior to cut 1) and also so the wood didn't change to skew results.
Next 461 with RSLH chain
cut 1 oak log #1 - 10.4
cut 2 oak log #2 - 11.6
cut 3 cherry - 18.3
then 660 with same RSLH chain
cut 1 oak log #1 - 9.6
cut 2 oak log #2 - 10.9
cut 3 cherry - 17.4
- 660 did beat 461 with both chains. Considering it went 2nd I give it a little extra applause.
- RSLH was about the same as RS with the 461.
- RSLH was slower than RS with the 660.
Over all I would say the 660 had a little more speed, but a lot more torque than the 461 with the 20" bar.
