Twin turbo set up
 

So if you were to run twin turbos, would you need two turbo boost controllers? Or could you run both from one?

It depends on how you have the intake plumbing set up, and if the turbos already have an internal wastegate or not.

To be honest from how you wrote your message it sounds like you need to do some more reasrch on the basics of turbos. Its easy to find info from google.

either way you oly have one boost controller. You must realize that thewastegate controls boost, the boostroller controls the wastegate.

If theres two internal wategates then theres two boost controllers.

find me a setup which runs 2 boost controllers! you dont want to run 2 boost levels into two differnt cylinder banks....

Phil means that one controller can run two wastegates.
