Do merge collectors work?
Do merge collectors work?
Yet they work–very well. The concept of a merge collector is similar to the theory behind a carburetor venturi, and in both cases, they work on the principle of building velocity through the venturi effect.
What are exhaust collectors?
Almost every exhaust system uses some form of a merge collector. The key role for this merge collector and the most obvious one is to combine the exhaust pipes of the different cylinder into one tailpipe, which could flow to the turbo or the tailpipe.
What do header collector extensions do?
What does the header collector really do? According to Hooker: “The major objective of the collector is to take advantage of the ‘secondary tuning impulses’ from the other pipes in the system. The influence of the collector is generally restricted to the rpm level below the torque peak of the engine in question.
What is a header collector?
Tri-Y Headers. The collector is where the primary tubes merge together. “4-1” and “Tri-Y” are the 2 main types of collector design. The 4-1 design brings all 4 primary tubes into one collector at the same point. The Tri-Y design (or 4-2-1) merges the 4 primary tubes into 2 secondary tubes.
How long should header collectors be?
Header collector length should be established so that its volume is at least twice the displacement of one cylinder of the engine in question.
What is a collector on a header?
What is header collector size?
Header collector length should be established so that its volume is at least twice the displacement of one cylinder of the engine in question. This provides an isolation between the header pipes and the atmosphere, ensuring that the collector does not appear as simply more pipe to the exhaust gas slug.
What size headers do I need?
