i have a greddy type s adjustable valve for sale if you like the mixture of pidgeon noise and want to be able to re-circ - it can be used atmospherically too. to re-circ you'd need a length of samco hose......only reason i'm going back to the forge is because i've got the whole pidgeon noise thing out of my system now LOLhelloo, i need some insperation on what dump valve to get and how well they fit and where they fit, want to make it look nice and not just bodged on:thumbs:
