Finished porting the husqvarna 346xp. Big power from a little saw. Little red race saw build shows up too. for more product and service info visit the website worksaws.com/c...
Good stuff Joe. Can't comment on any experience with the oe 346, but I have a ne, ported by Mastermind. It's a good runner. Unfortunately, at the time, Randy was drilling out the tank vent mechanism, as it was causing a restriction with the increased fuel flow as reported by customers. Unfortunate, as after filling up, enough fuel had dripped out the tank venting into the intake elbow and into the air box housing that it backfired and caused a fire. The fire then melted the feed line, which sent more gas into the fiery mess. It caught the grass field on fire where I was cutting (was a dry early spring day, kind of spooky). I ended up throwing the saw in a pond to put out the fire. Randy fixed it all up, and I discovered that the echo tank vent works well, which he started using after that. I don't say this to gain clout or anything, just to give a warning about a bad vent.
Yeah man… that’s a freaking hilarious story in that I’ve had some crazy stuff happen and had a tree snap off in the middle underneath me from the whipping action caused by kicking off the top… giant chunk off another tree fling back towards and totally crush me and some crazy stuff… watching the area around you catching fire would definitely kick up the old heart rate some and you kept your head on and got it into the water so that was some great work of staying calm enough to handle business!!! Also great that mastermind is definitely the kinda fella who is going to make it right… there’s a good percentage who haven’t or won’t do that stand up thing.,. I’ve always been a 353 Lower rpm’s fan myself but they definitely can rip!
Great video, The 346 is my absolute favorite saw and i'm thankful to see the gains on the before and after porting. I WOULD LOVE TO SEE A 346XP TURNED INTO A RACE SAW WITH A 52CC BIG BORE PISTON, keep up the good work I love your vids
Sadly my 346 came with a totally destroyed big end to me. "running condition", thats life. After seeing these top results i may search for a spare part?
Does porting the 346 shorten the life or make it more prone to issues? I love my 346 OE but I’d be crushed if it shortened its life by trying something different with it.
That is insane! Considering that Husqvarna's new 550xp MKII is a pound heavier and "ONLY" 4HP -- what am I missing? Trade-off in durability or are newly mfg products just dumbed down from the factory to comply with manufacturing efficiency and EPA "green" agendas? Do you get 4HP from a stock 550 on your dyno? I guess there is always calibration / measurement uncertainty. That said, at least if repeatable, the comparison runs on the dyno are pretty telling! Just -- WOW!
You hit the nail on the head. I figure for general work, a 5hp saw that is lightweight carrying a 24” bar is just about ideal. Low fatigue and real world performance makes a great saw. These saws are so restricted that they add a bunch of weight that increases fatigue. So what is better? A large displacement heavy saw that is supposedly efficient or a lighter lower displacement saw that is tuned and breathing easy. My money is on the easy breather. If you are worried about longevity, add a little more oil to the mix to keep your saw happy. This goes for cars too by the way. Another thing, there is no way batteries can replace any of this. About the time you increase performance on a battery, you have an explosion and a real forest fire. These environmentalists are idiots. Emphasis on the mental.
@@dynojoemods2764Ok, thanks! Do you reckon it would make sense to combine a muffler mod with a base gasket delete on this saw? I mean, if your saw is in good shape and you don't feel like grinding away on your cylinder...
That's what I did to my 346. Now my favorite limbing saw. I don't exactly remember, but I think the squish was right in there desirable for a work saw without the base gasket.
