25 Mod OMC

[csh15n]

I'm looking for some info on expansion chamber pipes for a 22CI OMC. I've heard that open pipes work better but with not being able to run open pipes I would like to stick with expansion chambers. I'm basically looking for a starting point if anyone has some info, dimensions ect. it would be appreciated.

omc expansion chamber

I am using a horn but I am waiting for an expansion chamber from Lee Teitz. If I get it and test it and it works half decent I'll let folks here know.

May want to contact JR

Erik,

I think John Robarge (from MI) originally tried his 22 OMC with an expansion chamber, but I'm not sure if he had much luck. I know he is now running an open megaphone exhaust.

His email is: jrobarg1@ford.com if you want to contact him.

Good luck.

Mark
