    Hello Guys

    What do most guys use as a rule of thumb on an 8 cyl application, when deciding whether our Turbo systems should have an O2 sensor per bank? Is it stricly due to the type of setup meaning single turbo vs. twin turbo?

    generally you put the o2 sensors in the Downpipe. So if you have a single turbo you use 1 o2 sensor and so on.

    Thanks for your response.
    I do understand that you put the O2 sensor/s in the downpipe/s. But is that the only factor that you look at when deciding this?

    How come most twin turbo setups I've seen have only 1- O2 sensor in the drivers side downpipe?
