Currently running a Turbosmart 38mm Plumbback BOV on my GTM supercharged 370z making ~9 psi. Ive heard that other setups making a more “pleasant” noise when off throttle but haven’t heard a comparison. Anyone have input here or experience switching between different BOVs? The Turbosmart Raceport is larger than my 38mm BOV and also offers a plumb back option. Curious what you guys recommend as the best recirculating valve for my relatively low boost setup.
