Wiseco 372 dominant piston

[anysawpat]

So I've been reading about the wiseco dominant piston, is it a good choice if you want to bump the 372xp power up a bit. I know porting will wake them up ,but with out porting is this piston worth it?

I haven't heard of anyone using one personally but they look to be almost as much as a xpw entire oem top end so if you wanted to not port the saw and get a bit more power I would go that way.

I’ve used a half dozen of them. They do give a nice compression bump with only a gasket delete. Not quite as much as a pop up on a stock piston and turning the base or cutting the chamber.
