    I JUST LIKE THE SOUND OF THEM ,READING UP ON THEM,APARENTLY The main reason to use an external is that it can allow for more flow and better boost control,on mostly modified engines..i know ppl with ford rs turbos with them....some one said i cant have a external if my turbo has a internal lol its alittle confusing....

    Can't use an external wastegate on a K03 as its internally gated and there is no point on a K03 even if you could really either...

    My GT3071 is internally gated and I could arguably get more power if I went external gated but its not a major issue.... If you are going big turbo and chasing numbers then go external gate, if you aren't chasing numbers then internally gated is fine.... works for me :)

    You sound confused fella, between what a dump valve is and a wastegate, internal or external..

    DONT run without a dump valve, you will cause the turbo to see high pressure surge and strain... you will get the chirp/flutter noise but this is not a good idea for reliable turbo function
