I recently purchased a used 372 xp which I absolutely love but now have an opportunity to buy a newer but used 372 xp w/ xtorq. Is the newer saw a better saw? What is the pros and cons to the xtorq over the non xtorq? Any help would be great.
 
I wouldnt say that the xtorq is better. The xtorq does get slightly better fuel usage and has a wider torq band being it is a strat saw
Ok, does that make it a stronger saw? Which saw has a better platform for modifications?
 
Brad, Is my thinking right or wrong? XTorq's have had a problem with burning down, due to running lean to decrease fuel usage. Seems like if you use less gas, using less oil and decrease bottom end lubrication?

I have not heard of that. I've not heard that about any strato saws. Matter of fact, in a stock saw, strato saws generally have more torque with similar reliability.
 
There was some issues with earlier 372 X-torqs in my neck of the woods with the lower ends, generally looked heat related. These generally failed early and were replaced under warranty. Haven't heard of any issues lately. I might add that these were saws used in commercial environments running near nonstop all day in the summer heat as well.

Guys, I appreciate the info. I just wasn't sure if I should buy the newer saw since it is same money as I paid for the XP, essentially. Didn't know if I would have a better platform for possible future mods. No question about it I absolutely love this saw. Remember that my previous saw was a 455 which served my needs but this saw serves my needs so much quicker. I think that I will just stick with the non-xtorq 372 because it sounds like that would be best if I decide to mod it in any way.
What mods does this saw respond best to without sacrificing reliability?
 
For easy gains on the 372, you can do a muffler mod and usually can remove the base gasket and replace it with sealant like Motoseal or Yamabond. You always want to check your squish if you take the base gasket out,but you normally can take it out it on this model without a problem.

The x-torq will weight around a 1/2 lb heavier than the 372. The x-torq cylinder is longer and heavier than the standard 372 but it it's also a strong runner that will use less fuel.

The weight difference is more like 4oz- it matters for us 240lb weaklings.

I remember Hamish and some other dealers posting about this in a thread awhile back. The subject was about 576 reliability issues and they agreed the 372 X-Torq's were having some bearing issues. I will see if I can find it.

Here it is.
576 xp. Any good?

Note, my 575xp is running fine. I purchased it new. She’s mean with a 28” bar with full skip chisel chain. I know it was replaced by the 576xp because of bearing bores in the case had problems I think.

The 372xp xtorq has two smaller thin vertical ports above the intake port. Not sure how that works yet.
 
The piston is def taller to accommodate the strat charges, but I am pretty sure the stroke is the same, resulting in the same torque lol.
Anywho I did see one video by Afleetcommand or it could have been hotsaws saying that the air charge for the X torque is just raw air with no fuel, resulting in less lubrication of the piston... I know for a fact that their is no air fuel charge and just air for my 455 rancher on the strato side, other saws may vary.

Btw Brad I’ve seen a few of your videos on YouTube, saws that had your work done, your famous bro! In a good way! Nice to see you post here!
 
My xtorq the upper section, half moon port there’s no separator between both upper and lower ports, the upper port is getting the fuel mixture. I think someone worked on it already.

Those two vertical ports could cause it to be lean. I’m thinking about running them all on 40:1.

My plan is to port and polish it all, change the port timing and advance the timing like on the huskys reps saw I put together.
