wastgates & boost controllers--general questions
I know there are two types--internal and external. I have heard external is the way to go due to the limitations of internal as far as boost pressure. Would someone care to explain how a boost controller interacts with the wastegate, and what the primary differences in external wastegates are among the different manufacturers?
Also, I have decided on a T3/T4 turbo, and I am wondering what the minimum PSI is that I can run with it until I get some fuel management. Is there such a thing as minimum PSI? What is the T3/T4 "default" boost pressure. Or does that depend on what wastegate I get?
Are there two versions of the T3/T4 turbo---one w/ internal wastegate, one set up for an external wastegate? If so, how does one tell between the two?
