Steve, Bit like my exhaust mod!

 

HI STEVE did the STIHL timber boys run a 661 when they 1st come out as there was big show germany was the you telling me about what bar size on it thanks jon

 

Hey Mendip, Yep we ran 661s in Germany, They did go quite well, Lot lighter weight wise. Not really had much more of a go on one then that though, i"m sure Stihl will have it sorted soon

Hi Steve, Great first impressions mate! Had a little run with her today she sings! and torque is way way better. Only some big willow today so not a real test but you can feel that the saw just wants to eat the wood!! Cheers Bud

 

I'll try to have some vids up soon guys, comparing my stock 660 with the Spudded 660, they are running differant sprockets at the moment so once they are both on the same size we'll have a good comparision.

 

Yep we'll have a day out with some saws sometime. I'll try and get some of the guys with hotsaws to show up

Hey Jon,

 

Ha Ha 10 out of 10 for effort but no saw is not for sale.

 

I would say a ported 660 is gonna be better, performance wise then a 661 due to the 661 being restricted for emmissions, Noise, Etc, But saying that, the stock 661 is going to be a good on fuel, emmisions, vibration, and it will still pull a big bar. we used a 18" on stock 661s for the world championships and they run great.

 

Not sure how many mods you will be able to do to a 661 due to the M-tronic, Spud may know more ?

 

Dont want to derail spuds thread to much but i'll try to get some vids of a stock 660 vs ported 660 and once the 661 shows up, we can race that!

 

Hope that helps a bit

That sounds good, I don't get the chance to put much of my work to the test so all input is greatly received.

 

The MS661 will be limited by the strato part of the saw, a mufler mod and slight internal mods may be a decent way forward.

 

For a "money no problem" option, experimenting with turning down piston crowns/squishbands and cylinder bases are a possible option to up the compression but with autotune, you have no control over the fuel system which is always a worry:blushing:

 

Thanks Chris for the input, all much appreciated.
