I bet my neighbors loved me this evening! I've been wanting to compare a bunch of saws and tonight was the night. Saturday is supposed to be in the mid 90s so I decided to get 'r done tonight while it was in the low 80s/upper 70s.
I was very curious to see how the 665/7910 hybrid would compare to my 372 and 2171, and to the 390 for that matter. I've also wanting to see how the 372 and 2171 compared. These were all running the same B&C
All of these saws are newer builds with little run time on them, with the exception of the 390. I've been running it for several years now. All are ported except for the 5105. It is only muffler modded.
First of all, you'll notice that I hit a pretty big knot in the wood on several of the cuts with the 372 and 2171, so take the cut time comparisons for what they're worth.
The chain was freshly filed and the rakers set using the soft wood setting on my progressive Oregon gauge. It's a hungry chain and self feeds very nicely. I'm not sure why, but I had trouble with my cuts when running the 372.
The 372 and 2171 are virtually identical. The 665 hybrid was 12% faster than the 372 and 2171. There's a little more in the 665 as I left it a little more on the rich side than the others. I'm still getting to know this saw. The 390 as another 13% faster, even with it being last to use the chain and the wood getting a little larger. All of these saws are phenomenal runners. I'm quite please with how they all compare, size differences taken into consideration.
What really surprised me was that the little 340 with the 346XP topend just barely edged out my 346XP. I wasn't expecting that. I do have some kind of tank vent or carb issue going on with the 346 though. Never the less, this little 340 walks the dog! Both were running the same B&C.
Cut times from the 5105 can't really be compared to the two Huskies. The Huskies are running .325 and the Dolmar is running 3/8. That give a pretty significant chain speed advantage to the 5105. I hope to port this 5105 on Saturday, so will use these cut times to compare it to.
372XP - Triple Port muffler
2171 - Single port muffler, ceramic bearings, Wiseco piston
665/7910 Hybrid - MicroBlue ceramic bearings, Falicon trued and welded crank
390XP
