If you have a turbo/kit with zero lag, it means that you will not make power past 4000rpm, because in order to get "zero" (although there is no such thing) lag, you need a tiny turbine housing which just don’t flow enough in the mid/upper RPM’s. These engines rev to 7,500rpm, so use the RPM’s.
Superchargers…there are two kinds. There is centrifugal and roots type. With the centrifugal you will have your boost pressure (resistance to flow) increase with RPM’s. So there goes your “zero” lag out the window.
Roots type (Eaton for example) is a positive displacement pump, and builds boost instantly. However, it will only make good power in the lower RPM range, and suffer greatly up top, due to many variables that I won’t bother getting in to.
You do also realize that having a lot of power/boost in the lower RPM range is very hard on the engine/rods as well. This brings us back to the question, why do you want to have a “zero lag” setup?
