Elaborate a little on where you got the dimensions for the templates??

 

[tree monkey]

I use porting and pipe software that gives me the pipe dimensions, basic math for the shape, and cone layout software for the pattern. calibrate the printer to the software with a printer and print the pattern.

That is some pretty impressive craftsmanship. And a lot of work!
Pretty cool. Mind explaining how and why an expansion chamber improves performance.

I gotta be more careful of what I post. yalls makin me type. I don't like to type.

i'll give ya a basic rundown of what I know.

the pipe creates a vacuum that helps draw the fresh charge into the cylinder, and the pipe. a sound wave pushes the fuel in the pipe back into the cylinder after the transfer port closes, before the exhaust port is closed. the center line length of the pipe determines the rpm this happens. long pipe, low rpm. short pipe, high rpm. a small belly in the pipe gives a wider power band. a larger belly gives a narrow power band and higher peek power. smaller stinger diameter make more power but more heat as well.

I don't know mutch about cone angles. my software takes care of that for me.

clear as mud eh

tree monkey, what all does that software need from you for inputs?

 

[Deets066]

Talkin to Treemonkey is like hookin a big fish, just when you think you got em on the line..... He jumps off and swims away.

Which style of pipe do you prefer personally? The wrap around style or the Viagra style?
