Over the past few years, a number of folks have tested a bunch of motors with pipes and cans and have a decent starting point for header length.
Problem is it's scattered all over the place between multiple forums and in multiple threads and between banter, LOL.
Brad and I have been slowly putting this stuff into a standardized spreadsheet format. I hope over the next week to finish updating the database and will slowly keep adding to the posts below. If you have any testing data, send it to me and I'll put it in our database and update the respective post. This way all of the data will stay at the top of this post and we can banter below and ask Q's or discuss results.
* 30-40cc Engines
* 50-60cc
* 80-100cc
* 100-120cc
* 150-180cc
* 190-220cc Quads
* Special (4-strokes, radials, etc)
Cheers
Trevor
