I have been doing searches and can't find an answer to my question. I am going to built my own grainger style valve and i want to know what size nipples to use. The wastegate can has a 1/4 inch nipple on it. The ones I see for sale all seem to use a smaller nipple size then that. I plan on cutting the brake booster line to supply the line to keep the hose short. Would using the smaller nipples create a restriction slowing the wastegate to open causing a spike? Or would the added volume of a bigger diameter line create a spike? Second question. On the wastegate side of the valve I know it needs to vent the wastegate can when not in boost. What size hole needs to be there or would an adjustable bleed there allow me to fine tune my set up?
