Yet another pipe length question

[BradV]

I searched this forum and there are lots of threads on pipe lengths for a CMB90 but no mention for a CMB1.0.

Does anyone out there know if the same length is suggested ie start at 12.5 inches and work back or should it be a little longer?

You can start at 13" and shorten it with experiments.

Does anyone here know what would be a good pipe length to start with for .12 size motor, using the MACs 1110, 2.5cc pipe. The motor is an O.S. .12 tr turbo. Thanks, Rick.

Richard, you should have started a separate posting for this one but seeing how you're already here, 6-3/4 to 7".

Hey Ron,

Is that measured from the glowplug, straight back or following the 180 degree curve of the manifold around. Thanks for the reply, by the way, did you ever start making those sponsons for the HH boat, I still need them. Thanks again. Rick
