Hi all im looking into fitting a dump valve, i know ppl say it cant be done but i have an idea, first buy a low psi valve about 5psi adjust/replace spring to lower it to hopefully 1psi if the valve still doesn't work i could then buy a Spiramax "supercharger" i fan in the induction pipe that will give a kick of about 2psi then hopefully i should get a dumpvalve sound im gunna spend £200 trying to do ill keep people posted on how it goes.

If any one has any ideas please tell.
