Look at the transfer inlet AND the intake port. Then ask yourself how it makes 10hp using those small passages.Just something I noticed with these strato saws, figured it could start a good discussion.

One of these makes about 10hp and the other is around 4.5hp
Knew the intake was small, but didn't realize it was that small.

Carb isn't divided. Intake is though.Yes, bigger carb, but split design, as well as the big one doesn't go anywhere near the RPM of the little one reducing its requirements in that respect. A bunch of math will explain it best, I believe.

The strato inlet area appears similar.
The outlet area is for sure smaller on the 550.
I just found it mighty interesting is all
Yeh the 550 has a longer strato length. From the boot to the first entry to the cylinder wall.Like Randy said, it's the length. I can imagine it taking less than a blink in time to fill.
Look at the transfer lowers.Just something I noticed with these strato saws, figured it could start a good discussion.

550 has large lowers for sure. All the 5 series husky are rather large.Look at the transfer lowers.
Yeah, I think the stuffed huskies hold a lot of their case volume in the transfers. They also push the flow out to the sides a lot more abruptly.550 has large lowers for sure. All the 5 series husky are rather large.
