sorry bout that RR2... not ignoring you..never would. you have too good of info to ignore you!!
the saw does outperform the 660..the 066BB makes the bulk of its power in the upper 1/3 of the rpms....u keep it up in the powerband and it will really pull. it doesn't do bad down low it just really comes to life when u hit the upper 1/3.. actually having a bit of carb problems with the saw...nothing that dave did...he did great work on this saw!! it is just acting up a tad..ive talked to him about it and he is going out of his way to get it lined out...and we will get it going properly right away!! btw i ran the saw to start with with a 8 tooth and it pulled it real well..but i jumped back down to a 7(what i run on all my saws) and it will really pull it...when i get the chance im gonna put the tach on it while it is in the cut..i know it it pulling strong
If you feel the need for more exhaust, you have pleanty of room to put another pipe into the front muffler cover. Or you could just buy one already made from me. Loads of guys with modded saws are going with a "triple" ported saw.
What kind of wood are you cutting with those bad boys?
yea i haven't gotten that far not gonna lie. just curious,, what u charge for your covers??i typically use the factory dp covers on my saws.. as for the type of wood i cut. it is exclusively hardwood (alot of big red and white oak, hickory, beach, ash, poplar, hard maple, and a bit of river birch and soft maple-usually pretty decent sized stuff. 066/660 (24")is my big saws, that i run almost exclusively and 460/046BB (20") is my small ones that i use for bucking up logs.
i ordered some of the foam grean weenie airfilters(5) from madsens today and im gonna alternate between them and the K&N airfilter
