Husqvarna 357xp hybrid build

[beaglebriar]

This could be the baddest hybrid ever! Excited to see that video!

Here's a video of it. Not too bad and it does feel like 70cc power. Nothing started melting or falling apart. It definitely feels like it can gain quite a bit if I increase the intake duration.
The chain stayed pretty dry on these cuts so the oiler isn't working at full capacity. That definitely needs fixed.

Looks strong and sounds good too....PORT IT....PORT IT!!!

 

[huskihl]

Sounds good Jim. No porting yet in the vid?

Dude that's an awesome saw... How much you take off the jug?

No porting yet. I wanted to see how it runs before making that decision.

I took a good 16th inch from the squish band and nothing from the base.

Like you said, it has a strong sound to it. Ought to port nicely

 

[BGE541]

So what's the price (non ported)?

 

[lwhaples]

Nice strong sounding lite saw.

 

[smokey7]

Very nice work. I always enjoy the frankinstine saws like this.

I've been comparing its cutting time to other videos of my ported 372xpw in that same log and I believe it is stronger than I originally thought. It's running a 26", brand new skip chain and the rakers are filed down below where the sweet spot is for this saw.
Here's a video of that saw with a much faster chain to compare it to...

Hybrid isn't far off the mark at all.

I'd rather build another to sell. I'm porting this one to see what its potential is. I'm not going all crazy on it. The ports are smaller than what you'd normally see on a cylinder of that bore size so I'm just doing a little reshaping and I'll also put the ports where they need to be. The main thing is the tiny intake that's about 8-10° too high.

That's one hell of an impressive pile of sawdust there Jimbo! I'd say the hybrid is holding its own especially in wood that big. Chit it'd probably be a monster cutting 8x8's.

Oem or AM cylinder ? When I just did my 272xp I thought the intake was huge.

Oem.
Holding the 272 side by side with a 372xp and xpw shows a pretty good difference. It looks like it could be as much as 4° smaller.

I see, your talking duration not width. Thanks for documenting such a cool project.

The 359 bolt pattern isn't square is it?

 

[Chainsaw Jim]

No it isn't. The 272 cylinder collar keeps the alignment so you know exactly where to go with the holes.
