Moparmyway ported 880
36” 404 RM 9 tooth in hickory
First few cuts, still tuning her

Pretty Bad ash! Were the sparks from the chain?

 

[Moparmyway]

Couldn’t load her up enough with the 404 and an 8 tooth

Sparks were from hickory ...... she blew down last month and has been getting harder & harder ever since

Were you running square or semi chisel Kevin?
Saw definitely has some powah!

Amazing power Kevin but to me, it almost sounds like it has nearly too much advance?? Is it popping in the cut a little?

Not really up on all muh codes.

Unreal beast of a saw, and a nice stick of wood too!

Where does one find a 9 pin rim sprocket? Is that a saw racing item?

Ddave sells them.

Saws that don’t suck pop with open exhaust and rich conditions. If it were timing advance, it would begin to pop more as the load increased

It’s definitely not for the dainty saws .......

I don't have an expert ear but those sounded like it was going to 4 cycle here and there in the cut... Just rich. Crazy strong saw right there.

Did you try slamming the brake on mid-cut to see if it had the powah?

I would have if it was my saw ...............

BUT

I do believe that she would have just walked across her brake without even a hiccup

9pin .404 is massive! I personally don't own a saw with the balls to pull chain in Aussie hardwood with a 9pin in .404 RS and 25inch bar I'd smoke clutches is about all lol

I'm with you. Changing from an 8 pin to 7 pin sprocket gives you a 12.5% increase in torque (maybe more if you add in the reduced chain frictions) and still produces great cut speed.

IMO, unless you really have a monster saw (or just want to cut softwood cants) it is the way to go.

For most of the hardwood that I cut, I have found that full comp chain and a 7 pin rim is the best way to go.

IMO, the 7 pin also puts a lot less stress on your bar, clutch and saw.

Do you mean 7pin in 3/8 or .404?
I like 7pin in .404 the chain speed is close ideal for me and my stock and lightly modded bigger saw's and what I cut. I think that's why a lot of guy's go 8pin 3/8 that's close to 7pin .404 as far as chain speed goes it's a good chain speed for a bigger working saws IMHO or maybe I'm way off lol
7pin 3/8 is like low range 4x4 gearing.

 

[MustangMike]

You are correct, but I prefer 7 pin in both sizes and would only use 404 on my larger saws.
