We look at the advantages of twin scroll turbos, discuss how they work and how to set them up. People have used twin turbos in the past to address many of the problems you hit with a single turbo and the twin scroll turbo offers a neat drop in upgrade and provides many advantages. Read More...

Inside an engine the rotational speeds typically reach 6-7000 rpm and, the higher the speed, the more critical it is to ensure that vibrations do not occur.… Read More...
