Post up your ported cylinder Artwork

The 660s I've done were equal to the 066 with aluminum flywheels.

Not me,not really close even but you run a higher exhaust than I do and that will even it up some.

Yep.

Little 7900 intake and lowers

MS660
Built to permanently run 36" 3/8 8 pin

Wow, thems some serious uppers there.

Also, what do you have going on with the base of the intake?

 

[Savage Saws]

There actually not that big Tony. I only had to raise them 3 degrees after machine work. There just cut realky flat with a super tight corner.

The intake floor is raised with Devcon compound F. It would have been fine at 83 for a saw running a 28" bar but this guy is a gorilla and i wanted as much velocity to fill those transferes and fingers as i could get! The saw holds mid to low 11's with the bar burried in a small leaf peppermint stump.

Ahhhhh its been filled.
Thats why they look like that.
My 066 running a 288 piston has its intake down around 82 and I have been thinking of raising it up to about 76

Where's the exhaust? 98-99?

What burr do u use to get that tight of a corner?

Beautiful stuff.

I'm trying to understand how fingers work on the intake side.

Seems like they'd interfere with loop scavenging.

I thought that too Al but, every time I've used them they seem to gain and hold better in cut RPM. They're main purpose is to get the previous charge moving towards/out the exhaust with a super high pressure burst of mixture with minimal volume.

It probably does add some additional volume to the new charge but it really about more efficent scavenging with minimal mix of the charge.

Thats my understanding of it anyway..... could be completely ass about.

 

[Savage Saws]

Same goes for opening the exhaust side transferes first on a quad port. Seems like it would form a wall of fresh charge infront of the previous charge causing mix of the two and incomplete purging of the cylinder.........if you get it right though, you better believe it works!!!

Jeez, thats working the memory.
99/123/82.5

I don't think it will gain much if any.

Looks really good

Nice port work

Thanks for sharing

Most importantly welcome to the site. Yes there is a difference here

Welcome, and thanks for sharing your beautiful work. I'm certainly no expert, but when looking at your finger ports I was thinking they would function similar to a bridge port.
