1. How EXACTLY does a boost controller work?

I understand what it is supposed to accomplish, i'm just a little unclear as to how. Does it bleed off boost pressure from the charge pipe or does it actuate the waste gate, or something else?


2. In regards to a stock FC turbo-

I don't have a waste gate actuator so could i just wire the internal wg shut and plumb in an external wastegate ( i have to make an exhaust spacer anyways)

1. It controls the wastegate allowing more exhaust to pass through it for less turbine rpm. http://en.wikipedia.org/wiki/Wastegate

2. I'm not familiar with the stock fc turbo, but I think you could do it, but it doesn't sound like a good idea.

You could wire/weld the flapper shut, but you would have to find someone who can weld on and external wastegate to the stock manifold and I don't know to many people that could do that.


Another way to do it is to have someone make a divorced downpipe for the stock turbo. Remove the stock flapper and put an external there.


What happened to the stock wastgate actuator?

I didn't come with one.

Wikipedia is definitely a pretty good place for basic turbo information. That said, there's some very good books on the market for relatively little money. Corky Bell's book is pretty good. Better yet, here's my own take on the subject that's about half the price of Bell's. It should tell you pretty much everything you wanted to know about turbos but were afraid to ask: http://tinyurl.com/yx4kbc
