btw..if im not mistaken isn't a stage 4 for like all out drag races only?
uh.
When you drag, you want a small turbo.
the way it works is, the bigger the turbo. the more it has to spool to build pressure. the more exhaust the engine pushes out, the faster it will build pressure.
in dragging, you will be idling, and you dont want turbo lag.. so you get a small turbo so it doesnt have to spool as long.
twin turbo means that you have 1 big and 1 small turbo, that way you get no turbo lag.. and it increases your peak power.. because you can have a HUGE turbo.
