Thread: 044 vs. 046 for Stihltech

Hey Stihltech, I've owned both the 044 and the 046. There is not a whole lot of difference size wise. Technically what is it that makes the 046 so much more torquey than the 044? Thanx. Rich.

044 spins 12000 and 046M spins 13500

My 044 manual says 14,000 for max RPM's. Rich.

For starters, there is .5 ci difference, which translates into over one half horse more power. Transfer ports also make power. The power has been upped at least once on each model. Differences in intake and exhaust size.
I have cutters running both, most like the 046 for the extra power, but the guys with a better knowledge of cutting will use an 044 just as much, some prefer it for less weight. most of the logging around here is done with 046, only a few 066 users anymore.

Thats funny you say that stihltech, most the guys around here use the 066, they say the 046M boggs too much for their tastes.

I thought a 46 to a 44 was as a 66 is to 64, or even 88 to a 084
same size displacement but carb and muffler mods??

also whats the difference beteween mag's, supers', av, farm boss,
I hope its the carburator ?

mag and super your getting more displacement. av = anti vibe

You guys are pretty much right. The larger number saw does have more displacement, usually a larger piston, with crankbearing improvments. A carb alone is not how Stihl does it.
Mostly 20 inch bars around here as the big timber is about gone. No complaints about bogging. They are using 66's on wood processors.
Revs are great, but in a working saw, some torque will make more wood, IMHO.

Once I opened up the exhaust with a second port. My pre EPA 044 runs darn near as good as an 046. Rich.

Jiml , ibet your in alot of hardwood ,use mine when icut big hardwood, or in the bottoms cutting big pine.

yup mostly hardwood.
