Topic: external wastegate plumbing and tech inspection
First post here. We are in the process of sorting out our newly acquired POS and getting it running and shifting again. The aforementioned POS came with a turbo setup of unknown provenance with an Chinese knockoff external wastegate (which needs some TLC). The wastegate empties to a short dump pipe (about 18 inches) straight down vertically from the manifold. The pipe ends just under the radiator line.
Question: Does this need to be fully piped to behind the driver?
