pipe length?

[Mike Cathey]

I have an Al Hobbs 11 cc pipe and I'm wondering if anyone knows what pipe length is a good starting spot for a 14 lb. roundnose 1/8th scale boat. It is very similar to the AB 67 pipe that was made prior to the turned billet ones they call the AB 67 now. I measure from the glow plug to the divergent/convergent seam.

11 1/2 and shorten as needed. Worked well on my RedMan pulling a `1460
