[jmssaws]

They all sound awesome Jason. What's the compression on the new TSS build?

180 or 190 im guessing.
i didn't check it.

Cool. Real nice.

066. 7.2 7.0

Idk if these vids will help ya Jason. I just read this and I'm not sure where your at on numbers Or opening tunnels, so on. But hope they help. Lol. This saw is running lgx in crappy oak.

 

[Miller Mod Saws]

36" bar rs chain buried in oak. IIRC. Very nice thread btw.

 

[jmssaws]

the exhaust has been raised 3 times,the entry angle of the transfers have changed 3 times. its gained everytime.

the transfer tunnels have been worked on a lot.

gonna try opposite numbers on the other cylinder.

if it will run good with a high exhaust it should run good with a low one as long as it has enough bd and case compression.

i say the exhaust is high but not really,its around 98-99 with short bd for a quad.

The first video that says higher exhaust is at 97/121-123/80. 22 deg advance.

 

[Miller Mod Saws]

I'd have to look at my notes but I think the one I like md the most of the other 2 was at 100/118-120/81. All 3 saws are high comp saws though.

 

[jmssaws]

im going to try 102+ with 24+ bd and a intake in the mid 70's

 

[Deets066]

I bet 101-124/126 - 80 would make a nice runner

Excellent. Look forward to it.
