Yeah, actually, it does, when the header has to be 18 feet long to work at 2000 rpm.


You told it your engine was 1 cubic inch in displacement.
Missed that part. Thanks!

The pipe doesn't have to be that long for harmonics to take effect, and would only need to be that long for ideal pulse scavenging, and then that would also depend on the amount of flow and the speed/density of that flow.
