I saw a BOV mounted to an intercooler on a rally-prepped Audi 80 a while back. Granted, I don't think this was stock, I think it was done due to space requirements, and this was the
ONLY BOV I can think of which was mounted in this fashion.
I've worked on Porsches, Mazda RX-7 turbos, turbo DSMs obviously, Subaru WRXs and STIs, aftermarket turbo Mustangs and turbo Hondas, as well as other Audis,
ALL OF WHICH have upper-intercooler pipe mounted blow off valves or compressor bypass valves. There has to be a reason based in physics; I simply don't know it.
