I'm sorry and I know I may get flamed but I also think a few others may secretly want to know the answer too So Dump valve Blow off valve Recirculation valve What are the differences please I at present have a forge dump valve fitted but still have the old recirc valve as I can't fit the stupid blanking plate. I'm bore of the dump valve sound and have seen people replace for a forge recirc valve. What difference will this make. Sound? Performance I doubt thereis much. It's the sound more than anything.
