Rough way to put it is: X-torque gives chain speed at risk of heat and slightly less torque; better for falling where speed may be more... -

Older thread, but could be helpful… https://opeforum.com/threads/372xp-pre-xtorq-vs-372xp-xtorq.937/ I prefer the OE version. Around...

I went out today and dropped three trees in the mountains with the newly ported 272xp. One of them was a 24”+ standing dead rock solid...

I wouldn't have ever thought a saw could run at all with that amount of blowdown.

That makes sense. It sounds like I may benefit from a couple less degrees of blowdown (raise my uppers a couple degrees) to gain rpm in...

But to make certain we’re on the same page, blow down is the distance from when the exhaust opens to when the transfers open. It gets...

Not contradictory, just that I’m not relaying what I’m trying to say very well. Raising the transfers and raising the exhaust will both...

Had to reread it a time or 5, myself. I believe what he's getting at is a higher blowdown number (lower transfer roof) won't cut at as...

A couple more degrees of blow down usually makes it a little bit more forgiving, but won’t hold RPMs as well in a simple down cut. You...

Didn’t measure compression, but it definitely feels stronger. I put a ring in it less than a year ago, and it honestly hasn’t been run...

Yeh, No expert but I'd think the shorter stroke would call for less blowdown. I believe popular opinion for an 044 is 20 blowdown...

044 is 50mmx36mm 272 is 52mmx34mm I wonder how the bore/stroke ratio comes into play with blowdown. My 266xp that I ported without...

Mastermind was at least two seconds faster in the same wood. MOFO 440 hybrid was almost four seconds faster.
