I thought this was interesting. 572 a bit more rpm in cut and 7910 a bit more torque. Both great saws.

Seems like the 7910 edges it out slightly after both are ported. Close though.

he parked it at my cousins overnight and i was there when he took off the next day
he makes damn good money doing it

Who ported them?
Normally the 7910 must be stronger with the same port job. 10cc more

I ported both of them, here is the same 7910 and a 372xpw that was ported by Mike Lee. Both good saws.

Squeaked a little more out of the 7910 with carb work and timing advance.

Now, if you just had a ported 500i for comparison ...

What do u change on the carb?

What do u change on the carb?

I put new gaskets in it, thinned the shafts, adjusted the popoff and drilled the main nozzle bypass to get the H adjustment into a more acceptable tuning range. I also took about 2/5 off the flywheel key.

That would be nice to have one of those here. It would be a great benchmark.

Too bad the timing and carb adjustments are not shown separately, they can each make a big difference.

Together they were worth about 3-5% on this saw. Of course this depends saw to saw, certain models like it more than others.

Jonsered 2152 with an XS 346 cylinder, 3/8 chain, 18" bar. Very good torque, just like I wanted.

Ported 501p

Both are 50mm bore. The 044 is a touch more high strung. But both are fairly close in performance with a 32” bar.

Serious question, do you log with a tach?

Nah, only testing sir. Lol

Are you setting all these saws at a certain rpm or just curious what they hold in the wood??

Just curious what they do in the wood and check tune after cuts. I think I do better without the tach sometimes lol, it can be a distraction.
