Nothing but 32:1
660 and 880 running 12 tooth .325
its only called 3/8 because the difference between .367 and .375 is 3/8s of ef-all

The difference is really small, unless you use the wrong numbers to calculate theoretical chain speeds, like Madsens do....its only called 3/8 because the difference between .367 and .375 is 3/8s of ef-all
Isn't 3/8's the width of the chain?

Seems a little silly at first. But the distance between the 2 rivets on a tie strap may not be the same as the distance between the rivet holes on the drive link. By measuring 3, then dividing by 2, you get a consistent number.
As far as the width of the kerf, I think that varies with the design of the chain and cutters. Narrow kerf chain is certainly narrower. And all conventional chain gets narrower as it is ground/filed/worn away.

A similar 3/8ths running on a 7 pin and a .325 on an 8 pin will cut very similar.
A .325 has more cutters per foot but the 7 pin 3/8ths rim is bigger.

Surely, but what does that really prove - that I missed in earlier posts in this thread? My guess is nothing! :msp_wink:
Hello, I'm new to this site but wanted to know if my Dolmar with a .325 x 7 would be better with the 8 tooth sprocket. Also I put the 5100 muffler on and is this good enough for should i still port that? It has the stihl RC chain.
thanks
There is only one way to find out for sure, trying the option yourself. Rims are cheap....![]()

SawTroll - can you usually change a sprocket without having to add or remove a link from a chain?
Thanks.

I'll answer for the Troll. Yes. I go between a 7 and 8 on my 385 with no problem. More than enough play in most tensioners to make this work.
