My 441CM was faster than the 660. I put a DP cover on the 660 and the 441 was still faster. I put a 8 pin sprocket on the 660 and then it was faster. I'm sure in bigger wood the 660 would have been faster stock. The RPM's the 441 turns made it tough to beat.
My buddy has a 660. I'll do a race with him at some point vs the 441 and get video on my youtube channel. Not sure when, but I'll do it. I don't know how much quicker he'll get through. He's running a 32 inch vs my 25, so it may be more a level playing field than the same size bar[/QUOTE]
Stock for stock? Gonna be close. If modded? 460 wins!!! By a lot In wood under 25".... Over that, and the 660 shines it's true colors!
Both are unmolested... Am thinking of putting a few $$ into one of them, probably the 460 as the 660 only has like 20 hours on it
Stock 460/461's have more HP than 660's despite what the factory specs say....already proven with dyno tests. After porting, the 660 wins in HP at all rpm ranges.
A 8 pin might work with a shorter bar but I have a 25'' bar on mine. I don't think it would have the power to turn a 8 pin with a 25'' bar. The 441 is not a real torquey saw.
Yeah...I have a 25 inch bar and several chains for that size. I have never tried the 8 pin with that set-up. I have the 7 pin in the field bag for when I switch back and forth.
There's an easy way to find out....For firewood cutting, I love the 16inch bar 8 pin set-up. My friend with a 32 inch 7 pin 660 set-up is happy when I help out on ground work duty during his tree jobs. He thinks that my set-up is a firewood cutting screamer given that a 660 has lower rpm and better torque for felling and bucking large stuff but not great when cutting up smaller stuff or limbing. I score free firewood, and he keeps the cash. A sort of reasonable deal...his wife leaves him to earn all the money, so I help him out any way I can.
If I'm cutting something small I'll grab smaller saw with a shorter bar. The 034 super is a good all around firewood saw. When I get in something bigger I'll get out the 441 or 660. I really like the smoothness of the 441.
I don't have an in between. The 290 lives at my house where I cut stuff around the yard. My 441 is the firewood saw.
I think the factory dyno results were on AS but the ported charts were also posted here. Chad did all the dyno tests.
