320guy 0 Report post Posted July 23, 2008 Log manifolds made properly can make good power. But the DA one isnt even a good design, it goes from a small runner from the exhaust port into a big chamber while making a 90* turn, any change in direction is going to slow the gases down (which means less energy to spool the turbo).
