Here we go fellers......all this talk about which saw is the hottest in the 50cc bracket has me wondering if the 346XP can be unseated as the top dog in the class. In the interest of science we need to know. :msp_rolleyes:

This video comparison will be in the same piece of wood with the same square ground chain. The chain was ground by mdavlee and has not been modified.

Here in my shop we have a low hour Stihl MS261. It has been woods ported with the strato ports nullified. It's blowing 205 psi with a cut squish band. The muffler mod is all within the stock deflector and is fully screened.



Next we have a new 550XP. This saw is still fully stratified and autotune. I can't be 100% sure about it's compression because I don't have the correct gauge for the 10mm plug hole. With my Proto gauge and an adapter, it's blowing 165 psi which is about 30 psi low if I'm allowing for the adapter correctly. It has a cut squish band and is woods ported. The muffler mod is a welded on additional outlet and all openings are screened.



I also just so happen to have a nearly new woods ported Jonsered 2153 that is blowing 185psi with a cut squish band......it's had a little carb tweaking as well, but everything is from this saw. No different parts at all. The muffler mod on this saw is a larger welded deflector in the stock location and it is screened as well.



Here's the video....

Be interesting to see how the auto tune would deal with a destratofied system.

I wasn't sure about the size difference but low and behold the 261 is enormous next to the 550. I was stunned to say the least. And the cut times you posted aren't exactly making me like this 261 - and I haven't even used it yet lol. This is an awesome comparison. I can see the 261 being strato-gutted but not sure about the 550. How would you even start to remove the strato features? It's not a divided carb setup.

I would rather have the strato intact on these saws. Some of the strongest saws I had the pleasure of building are setup like the 550. The 562XP, the MS441.....
