Highest Power / Lowest weight

[Rio95]

Not many folks run 681 Solo's, they're out of the game these days but those who own them know which saw wins the P:W ratio debate...

Just looked it up http://www.baileysonline.com/shop.axd/ProductDetails?edp_no=37338
Pretty impressive specs

Manufacturer claims:
Solo 681: 6.7kg dry PHO, 4.8kw = 0.72kw/kg
Dolmar 7910: 6.7kg dry PHO, 4.3kw = 0.64kw/kg
Stihl 661: 7.5kg dry PHO, 5.4kw = 0.72kw/kg

I've been working on a comparison table for this type of stuff - not finished, but I have attached what i have so far. Red numbers are estimates/unofficial.

What becomes more interesting is when you start comparing classes of equipment for instance pro 70-80cc backpack blowers, clearing saws in 40/50cc classes, 30cc trimmers etc. You start to notice a trend with Solo that the major 2 simply don't match.

How about 35cc top handles? Anybody got specs?

Here's my xls that has loads of saw data. It's actual results from a lab vice manufacture numbers. Metric units are hidden if you swing that way.

Here's an example.

I believe the new Stihl MS462C will take some beating.

What’s it weigh and how’s it do on bucking oak?

 

[pro94lt]

40cc? I own a 543xp, dolmar 421, and stihl 241. The 543 probably has this won even though I would much rather and do use the dolmar or stihl much much more. And the dolmar is actually lighter than the stihl... power wise the stihl edges out the dolmar but not in weight

 

[Chainsaw Jim]

I bet a 72cc 357xp has an edge in this discussion.

Just depends on what you're looking for.... actual test number look like this.

 

[sawfun]

The early 064's weighed 14.6 lbs and the Poulan 505 weighed 14.9 lbs. With a 32" or longer bar I would take those above a 7900. They can oil a 36" very well compared to the Dolmar.

How much R&d money did they spend on that 462 for a small gain over 460?

How much R&d money did they spend on that 462 for a small gain over 460?

They spent enough to make all the 460 owners rich men for the rest of their lives if they divided the money out equally among all 460 owners.

 

[rupedoggy]

This is just a WAG

50,000 460 owners and $50,000,000 research would be $1,000 each (you can plug in your own numbers) but apparently it doesn't take much money in Omaha to set you up to be rich for life.

 

[Deleted member 117362]

You could go out and buy a real saw with that $1,000. Husqvarna!

 

[dustinwilt68]

242xp 10.3 lbs-3.1hp and it turns 15,500 from the factory, hard to beat that at 42cc.

 

[stubnail67]

what about the echo 501p its around 10 pounds 6 oz? dry weight i believe in the 50 cc class... not sure if ya all are going by dry weight or fueled and oiled.....
