    They can turn alot more than that. Depends on saw. An alcohol 260 if set up for RPM might turn close to 18000 out of the wood.

    Haven't seen it, but I have atleast two saws that turn close to 17000.

    I see stock (without muffler screen) 200Ts hit 16k all the time. I turn then back... and the owner just tweaks them back up again.. Same on 026's

    My Fisherized Eager Beaver with the Mag-Lev bar/chain system revs so
    high, that variables of space, time and mass start to get things too complex
    to explain to you lesser folk, only my new engineer/r&d man, Simon, could
    explain.
    When the guys have used this saw, they have gone home and found their
    wives and children 10 years older, so as of now, we have no one that wants
    to run this hot little pistol, so we will likely switch back to liquid nitrogen
    and drop the "Fisher's" Synthetic Bar oil, and just use that crappy Stihl oil.

    I've built a 064 hybrid that turned 18,000 out of the wood on rich fuel and 19,800 leaned out. The saw was mighty thin though on the torque end of the scale.

    Just a dumb curiousity question here, how long can you keep a decent edge on a saw running at these speeds? :jawdrop:

    Well I built a Alcohol Sachs Dolmar 116 super that turned i tic over 20,000 out of the cut. I need to dig it back out and get some pink juice for her. Although a bud of mine had Jonsered SP490 and SP590's turning well into 25,000 range I did not push mine that hard.

    I watched Gypo in Clearwater Canada Have a 084 KD turn about 20K on a runaway till Rupedog got it turned off with a hand full of sod for a choke. One of the funniest things I ever saw.

    When I was in the Army learning how to fly UAV's alot of my instructors competed in various flying events one of wich was pylon racing. These little 40 cc demons swung 8 to 10 inch props at over 45000 rpms! They only had two throttle settings, off and WFO and when they fired you could really tell they burning either 95 or 100% nitromethane.:jawdrop:

    I don't want to go too far off topic, but Freddie Spencer ran an oval-piston V-4 Honda four stroke motorcycle in 1981 that redlined at 22000 rpm!.

    I have seen ms170's with that crappy carb on them do 15400 and apparently been that way out of the box. THe cylinder would be discolored on the outside from glowing, but still had good compression.

    You’re coming on a chainsaw forum looking for a pimp? That’s messed up.

    Some years back I had a Dolmar 116 with a Kriedler barrel/piston for a laugh we fitted a Gardner flat slide carb /EMC ignition Not really sure how may revs as the tach we had only went to 30,000 Rpm & a quick blip made it top out on the high stop Used to take it to shows & restrict it to a few demo cuts & put it away no idea how long it would have lasted or if it's still a goer as I swapped it for a 125 cc Kart motor

    I like when some of these interesting old threads get resurrected.

    Hey @Frank Rizzo, here’s some good examples of saws that would be ‘held back’ running relatively high compression.
    That’s what I’ve been talkin about anyway.

    Maybe this is what you’re shooting for?
    You’ve got a long way to go...
