Im having new intercooler piping made and I want to know where the best place to install the blow-off valve is?
I’ve not seen any conclusive results that prove that one position is better than another, but many people have different ideas about this. Some say that it’s best to have it close to the throttle, since that’s where the back-pressure builds from when the butterfly is closed and it will respond quicker. Others say that it’s better to put it as close to turbo as possible so that the valve is venting hot air rather than post-intercooler cold air, so that the inlet pipes after the intercooler are still filled with cool air.
