2 Power heads + 1 bar = ?

[Big Woody]

Wondering if anyone has used or seen used a 2 powerhead bar setup in recent times? I believe some have used this setup for milling. I realize they have to be tuned to similar rpms. I have seen claims that it is really no better than a single powerhead. Any first hand observations?

They do not need to be "tuned for similar revs" They do not need to be the same size or the same brand. A 7 hp saw will benifit form a 5 hp saw helping to move the chain and it will notice when the 5 hp saw stops running. Let's say I was pushing a car and you came to help me push, we don't produce the same horsepower but I would be glad you were helping push. If this were Hulk Hogan and Pee Wee Herman pushing the car, Hulk would still feel the load decrease when Pee Wee started pushing.

I feel the only advantage of a duel setup would be the increase in useable torque, i seen 2 Huskies 3170 bolted together last weekend at the saw races they were sharing 1 cutter bar looked impressive but the weight would kill you especially in a speed cut event. Over the years i have seen a few competitors running a twin setup but where are they now ??
Note the twin unit setup's were both Huskie powered.

It sounds like the idea that thay used to make that motercycle using 24 Dolmar engines,,,, again why?

Growing up, we used to use this kind of a setup for milling lumber, mostly planks. Anyway, we used one of these setups with Either two Mac 850's or when we got the 125C, the 125C on one end and an 850 on the other.

No rpm matching needed, the chain does a fine job of that.

Which reminds me...don't mean to hijack the thread, but what ever happened with the clip of the Oregonians and the 350 Chevy V8 chainsaw? Haven't seen that one in a while. More power always sounds like a large time to me!

I saw a set up bearing an 088 on one side and an 084 on the other, on-line some where. One of them was upside down and on of them was running backwards. Strange?

That is on Madsens site.


Sedanmans analogy of two people pushing a car is very correct.

I think if I look at that picture for very long it will give me nightmares.....I am not sure why. Maybe the thought of it spinning out of control like a big helicopter.

You wanna see that thing run??? come down to the Buckley Log Show in June.

is it reasonably possible to make the "other" engine run backwards so both engines can sit upright?

Where did you get the pipes. I would like to put one on my 460 or 361

kdhotsaw pipe on the 088 and a homemade on the 084.
