Wiseco 372 piston

[mdavlee]

Any one running one of these or know someone who is? I think Brad got one for one of his saws. Thinking of trying it out in my 2171 I'm putting together.

Is that the domed "dominator" one?

I have one of the original Bailey's Wiseco dual thin-ring pistons in a saw I've been running off and on for about six years. Parrisw machined the jug for me back when he was still into saws. It's been a phenomenal runner all this time. I've fell timber with it using 28" to 36" bars. I guess I can pull it apart and see what it looks like internally.

Here's a video of him running one of those pistons:

 

[mdavlee]

That's the one I'm thinking about trying. The lighter weight might let the crank live longer at 15k+. Oem mahle is $80 or so. I'll weight a meteor and oem when the meteor get here in a day or two.

 

[jacob j.]

I've not bought one of these but I have dealt with the seller before.

 

[mdavlee]

If it will help the saw last longer on the bottom end it would be worth it.

 

[beaglebriar]

How much weight would you lose if you cut a pop-up?

 

[mdavlee]

Probably not 4 grams worth of aluminum.

 

[Chainsaw Jim]

I think you can order it directly from wiseco with a set of ceramic bearings.
Brad did a thread on it over on as with a link.

 

[mdavlee]

I'm not worried about the bearings. I talked with tree slingr and he made his own with ceramic balls.

Andrew Wellman (Dominant Saw) is a good dude.

I looked on their website http://dominantsaw.com/collections/...o-dominant-372xp-50mm-high-performance-piston
They have one of Snelling videos of a ported 2171 with the Wiscoe piston at the bottom of the page.

 

[mdavlee]

Brads the only one I know of that's tried one. Probably not worth it unless you want to go really wide with the ports

 

[RIDE-RED 350r]

$110 is pretty typical for a Wiseco forged piston of that size.

No 51.4mm piston..

 

[beaglebriar]

I saw that they offered an all black piston for a little less. Honestly the price wouldn't be a deal breaker for me if the performance increase was significant or if it was proven to help the bottom end last longer.

 

[Chainsaw Jim]

The price drop on cylinder kits makes this a tough decision. Though I'm sold. When I buy another piston it will be this one with the bearings.
