Dump Valves

  •

Ok, so, i don't have a zx, but i still have plenty of zx based questions. One thing that I'm curious about is dump valves. Now, while they sound great, or at least i think they do, I've heard conflicting views about them, and whether they actually help, or hinder the engine, and only re-circulating dunp valves are actually worth considering. Anyone have a definitive answer, or perhaps can shed more light? Thanks

    I dont think there is 1 definative answer. Some people say that Dump valves are better some say that recirc valves are better.

    The idea of recirc valves is that it uses the air back onto the turbo spinning it up faster.

     

    I prefer recirc myself
