A Tale of Three Saws

[blsnelling]

181lbs on the 660 eh? Fat bottom girl or what?

18# 11.6oz

 

[blsnelling]

Are you going to run them in various sized wood or just one of the big'uns???

For stock testing, I only intend to test with 24" bars. Once modded, I'll probably put 32" bars on them and stick them in some of that Oak. If I could quit my day job, I'd do all the testing you want

 

[luvsaws]

for those that care, the fluid capacities are as follows:
7900- 25oz fuel 13.5 oz oil
390- 28oz fuel 16 oz oil
660- 28oz fuel 12.2 oz oil

Wonder why the 660 has a smaller oil capacity?

Figured so, was trying to be funny, guess it didn't work eh!

As usual though Brad, I look forward to these builds, I wish I had more time to get all these saws done that I have here. Don't know where you find the time.

I think that may be under utilizing those saws.

I always assumed the oil capacity had something to do with fuel usage. I know the 441 has a greater oil capacity than a 440 or 460 as you go longer between refuel/refill of the bar oil. This is just a guess, as I have know idea how the 660 and 390 compare in terms of fuel usage.

From what I under stand, they design it so the gas runs out first. But you shouldn't let the gas run out! LOL

+1... 70cc and 90cc are pretty close in speed until you pull out the long bars or should I say bury the long bars.

exactly!

LOL, from what I hear, you've never buried the "long bar".

So the 390 is better on fuel than the 660.
Another test to throw in the mix for ya Brad:hmm3grin2orange:

This is just a speculation. I have no real world evidence of this. The only time I have run these models next to each other is at a GTG. They were both heavily modded and I didn't run a full tank through either of them.

You may be right, but I sure have tried! Is it my fault I have too much bar for the job! LOL

Depends on how there ported. If the intent was for small bars and speed the 390 will win every time. If the intent was for long bars and torque numbers the 660 is gonna hold its own, although he should have ordered the R model with the high output oil pump for that.:hmm3grin2orange:

Hmm, too long for the job! That's not what Brad said about your "Long Bar" our West Coast long bar, and your long bar is two totally different things. LOL! 28" is short around here LOL

 

[Andyshine77]

The newer stihl saws don't pump out enough oil for my taste, I think this has more to do with eco friendly oil pumps than anything else.

LOL! I usually just run the 25" on the 441 but I have a 32" for those special occasions! I have buried it in oak, maple and pine a few times. I run a 30" on the J-red. Most of the time these bars are overkill in the east. What we give up in length we make up for in hardness of wood.LOL

OH GEEZE the endless fun I could have with that one.

Hmmm, I usually burry my 36" 395, but alas most of the time soft wood. Oh well, whatever make you happy I guess. Just like trying to stuff a marshmallow in a piggy bank!!

 

[mdavlee]

I never weighed the 660 I had. It felt a lot heavier than the 390 but that shows that they are real close.

I must have a European long bar cause I can only bring 6" to the table
