lenths of exhaust manifold

[ketan]

recommewnd me some standard book or a website for calculating lengths of exhaust manifold.we r using 4-2-1 exhaust system and about pressure waves.any cooperation wud be of gr8 help coz we r doin this for very first time.

If you are looking for a simple equation, you can google and get several links.

If you are looking for papers on theory, do a quick search on SAE.org. There are a ton of them, get one or two, skip the paper and take the Reference section to your library and get all those papers via inter-library loan.

Your third option is to get any acoustics book. Exhaust design uses the same equations as intakes but due to the simplicity of the system, they can be done in much fewer equations.

If you don't have any papers or equations to do your analysis with, on what did you make the decision to go with a 4-2-1 design?
