    OK, my location has been updated.

for 700  cords you could probably justify a firewood processor. Lots less work.

I’m trying not to get this post off course, but by the time you drag a wood processor into the sight, skid logs bigger than 6” (with some ten thousand dollar) skidder over to a seventy thousand dallor wood processor that they claim will cut and split 7 cords an hour, I can do just as good with a saw and sharp chain. We don’t skid logs, I chop them into pieces right where they fall, load then and I bet you that faster than a wood processor, “skidding logs take time and machinery, and wood processors take both”, thanks everyone for posting….

Still kidding around, huh?

7845Robert, it would help if you would edit your profile to show your location.   ..................

Yes mtngun, it would help       

i updated my pro, i'm cutting at 10,000 feet sometimes higher and sometimes lower at about 8,500 or so.... i should have posted that in my opening, sorry... Rob

You dont need a pop piston in a 066. Mine has been doing fine in big wood and small wood cuttings for years.

Even at the GTG's it was the 066 being chased at the top. Still running a stock oem piston with no lightening of piston or extra window opening.  Becareful of your builders, some charge $300 for added pop up pistons and their saws dont perform any better.

The builder has to know how to do more then just high compression with a pop up, it's all about the porting IMHO.

Buyers beware ask in PM's about builders. There is guys doing porting else where as sponsors that is just taking your $$$ for half the work. If it is all you have ever run you wouldnt know the difference, but when you show up to a GTG and see the real stuff. You soon be asking why.

Case in point guy shows up to Jan GTG with 2 saws from a very hyped up builder with pop up pistons a NE346 and 390. The 346 was one of the worst 346 i have ever ran woods ported. The 390 felt like a strong STOCK muffler modded saw IMHO. Both saws were 6 months old and SOLD after the GTG when owner seen how they compared to other woods ported saws.

Cutting at 10,000 feet is going to rob power for sure. Even at 6,000 feet you have 80% of the oxygen compared to sea level, and at 10,000 feet you have only 70%. Less oxygen, less power. So at your cutting altitudes, your 660 is like running a 440 at sea level (at best). Unlike humans, your saw cannot adapt to the higher altitude. A muffler mod would help greatly though. You need to get more oxygen into that thing.

How about a Turbo?

Now you're talking, i could just imagine after about three seconds or so it would start to wind up and that would be very cool, though heavier. instead of magnum or pro it would read Turbo Chain!!!
