MillerModSaws plays with a 440R/046D Hybrid

He allways does !!

 

there is a spot on the rh case i like to notch just because for safety ,with the slotted jug holes could be off a tad front to back ,this lil spot i remove with a carbide bit ,not required maybe ,but when my jug was loose could feel the piston hit slightly before bolted down ,something to look for anyways

 

And here's the intake. All I've did to it is widen it to the oem bevels and square it up. Sorry I forgot a before pic. I have not checked my ring end locations so I may widen it some more. We will see. Lol. By the time I finish this up it will land about 77°. On a 460 I lower the intake to 80°. I'm not going to on this one because of case volume. It will stay at the 77° or so I will give the final numbers.

 

Thank you. I'm still in mock up but I had not caught that yet..

 

The other cylinder may haft to get installed for a comparisson. I was just using my cases to port it but I have a couple 044 laying here that are mine. Just may haft to mod one of them too. Lmao

 

I was lying in bed and was thinking man if someone is following this thread. What if. I just wanted to make this clear that this is my saw and I will take it to the max. I believe where I am heading will make this an amazing runner but we will see. So please be cautious if you build one of these. The .072 and .040 is the max I could take. .062 and .030 would be closer to what I would do for a customer just to ensure longevity of the saw. Thank you for following along.

 

Top notch advice...
Following along.

 

Thank you. I just don't want someone to build the saw the same as me and it not handle it. If i take this saw to far I guarantee Ya'll will be the first to know. Lol.

 

Here's a before pic of the trans and they are marked at 102.

 

Here's the trans all done. I just cut the lip off the lower trans.

 

Here's the finished exhaust. Notice I didn't take any off the floor of the exhaust right at the piston. I'm at free porting now. So I didn't want to lower it at all.

 

Finished intake.

 

And this far back together. I need to check the intake still and see if I can raise it leave it etc.

 

I forgot to add I raised the squish band a little. It has .025 squish now. That's where u like to run a bigger saw like this. Especially if I'm gonna be pumping a lot of comp.

 

do you know what your elevation is ? Seems like compression raises some when i get my saws back from where they were done ,about a 2k feet elevation diff i think, i am about 300 ft above sea level

 

1030 ft.

 

.025 on both juggs or just the "D" chamber ?

 

On both jugs. There both gonna be pretty high comp and i like the security of the added squish. The other jug is on hold for know. I'm gonna put the 046D saw together and see what I got going and then I have a couple 044 laying here that are mine that I havnt got to yet so I'm gonna pull one of them apart and mock the other jug up on it so I can see how they run against each other. Or that's my plan anyway. The 460 jug is gonna be running a higher exhaust. That customer wants it built for a 20" bar.

 

I got it put together tonight and intial fire up. She has some issues so When I tear it back down to iron those put I'll get pics of the flywheel mod. It started and ran but acts like I may have a small air leak. And something in the carb box is funny. Won't idle down till I screw on the air filter. All little things but I will try to get them ironed so I can get you a vid.

 

I didn't post this last night I had lots of configuration on my mind. Lmao. But the numbers on this saw are 102/118/77. And comp well who knows. Dam comp guage have been a killer for me. Hopefully that fix is on order. My cheapo bit it, then my lisle bit it, and I don't think my motion pro is cutting it. So a new snap on is on order. Be here tue. Lol
