So, I understand the basic exhaust layout, and how the exhaust gases go from the manifold, through the uppipe, into the turbo, and out through the downpipe, all the while driving the turbine to compress the air going into the manifold, but I do get lost in the details...
Can someone explain the relationship between a boost controller, blowoff/bypass valve, and a wastegate? Do turbo'd cars come with wastegates stock? And as far as I know, the bov/bpv is only for when you take your foot off of the gas pedal and the turbo keeps compressing air, but it has nowhere to go besides back into the turbo, which is really bad. Is this all it does, or is it involved with the other two things I asked about as well to control the amount of boost?
