I'll put it this way, my ported 372xp pulls a 28" bar wearing 3/8" round chisel chain equal to my old stock MS660 if I'm not leaning on it while being a good bit lighter and with way better A/V. With a smaller bar, it flat spanks my old 660. I do miss my old 660, but eventually a 395xp will be what I buy to replace it, again for the A/V concerns. I've run a ported 346xp which was very nasty and seen videos of MS261s that both Brad and Stumpy have built and there is some amazing potential in them, especially for their weight and size. I get a kick out of running bigger saws, but when I'm actually doing a paying cleanup/removal job, or spending the entire day cutting, I want the most production for the least weight within reason. I just bought my 562xp and have less than a tank through it, so it's still very tight, but some day both my 261 and my 562 will likely be ported. The throttle response and added power in the cut is addictive.
"but some day both my 261 and my 562 will likely be ported."
There are two words in that sentence that say your not gonna do it.....SOMEDAY and Likely...
I've always been taught that when someone uses the words Maybe, If,or Some Day....they'll never do it....
Some day.... means No day.....Procrastinator....:msp_tongue::hmm3grin2orange:
:hmm3grin2orange:
Actually in this case "someday and likely" are used to indicate that I am married w/kids and therefore broke. If I was still single they would both be done in less than a month!!! I will be modding the muffler on the 562 as soon as she gets loosened up a bit!
Much truth in what you say. I love ported saws, but saws like the 7900 came from the factory ported.:msp_tongue: IMHO it has more to do with sloppy execution by the manufacturers than the EPA or anything else.
Anytime you raise power you more than likely shorten the lifespan of the engine. Hell you're removing the plating on the port chamfers. Sure you may get more wood on the ground, but lets be honest, who has the hard numbers on that? I honestly haven't seen anything 100% conclusive. IMHO the best thing you can do to a work saw is mod the muffler.otstir:
The Devils advocate I play.:smile2:
I've only ever run stock saws
Warranties are not a reason to live life stuck on the on ramp.
I "port" mine by keeping the chain sharp.
...My struggle is that there is nothing without a downside in an engine, more power up top is less down low...
Fair enough. While a poorly-ported saw may be good only as a high-rpm cookie cutter, the builders on AS seem well aware of the advantages/necessity of low end torque in a work saw.
