Three Cube Shootout!!!!!!!
« on: September 10, 2012, 08:36:01 pm »
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....

 8)  Nice and I am surprised by the outcome with the 2153 still running the 346 carb too.   ;D

Nice builds and details Randy.

Thanks for sharing with folks here so they can see the new ones ported too.

I've tried the Zamas from the 357s.....they sucked. The 199 is the way to go if a larger carb is needed......but Hell Kevin you already know that.  ;D

I could tell you 1 other carb that works like 199. But then that would create a shortage of that carb too.  ;)
